ETHGlobal New York 2025 Closing Ceremony and Finalist Demos I Kartik Talwar

[Music] for our fourth event of the year. We're back in New York. There's over 950 attendees here. This whole weekend is about building things and actually making ideas come to life. The companies that have come out might be global since our beginning have raised collectively over $500 million.

That's just the ones we can count.

Excited to start begin hacking in like I don't know twoish hours.

Everyone's so welcoming. They're like, "Hey, how are you? How are you?" And I'm like, "I know nothing."

Everyone's trying to learn from each other.

Day two, everyone is like heads down on their laptops building, hacking so they can win their prizes on Sunday.

Like when you walk into the door and you see like, you know, hundreds of people kind of all very like focused on their on their screens and everything. Everyone is really pushing boundaries, high energy.

My favorite crypto community. Two days heads down building something and you're going to learn more than you would in 2 months on your own. I don't know if it's because it's New York, but we have a lot of projects ideas around combining finance and crypto.

New York is the capital of crypto. I remember my first time being a hacker. It's fun, but also very stressful.

You're like super tired. You're barely like kind of functioning, but somehow there's still that like adrenaline that keeps you going. Everyone has a different reason for being here. You're almost at like on the breaking point, that adrenaline of like even if you don't win, you're winning at pushing yourself in building and doing something with something you've never even tried before. The projects in New York have have been actually really cool.

We're seeing a lot of really cool projects that are consumer oriented.

A lot of people are integrating AI agents um to simplify experiences. It's going to be a really tough competition out there and I'm excited to see who wins. Good afternoon everybody. My name is Cartek, one of the co-founders of ETH Global and I want to welcome all of you to the closing ceremony for ETH Global New York. Love this.

Well, I'm going to ask you to conserve a lot of your energy because we're going to clap a lot for the next 30 minutes. You are at an ETH global event. Our mission is to onboard thousands of developers to the web3 ecosystem. And this weekend was a hackathon and our fourth time in New York. 950 people were in the building.

690 of them were hackers from 210 different cities, 51 countries, six different continents, and 37% of them were brand new to web 3. That means they were existing web 2 developers trying to see what's possible in web 3 for the first time. People came from all across the globe. You can see exactly every city where everybody came from. But not only just the hackers, we had 192 partners who were here all weekend to help you build the things that you're excited about.

21 dedicated mentors, 22 workshops, and zero talks because this is not a conference. Not only that, we also tried to do things onchain with these wristbands. And people ate a lot of food and they met each other a lot. and 400 workshops were attended. Oh, okay.

I was like, I don't like myself on screen. Let's go back to the slides, please. Um, we're giving $275,000 in prizes. And we're going to talk about who won what. And, uh, everything that you get to see that came out of this weekend will be shown to you as a live demo.

I want to thank 27 of our incredible partners. So for the first ask for a lot of clapping let's give a massive round of applause to each of these companies starting with coinbase develop platform flow layer zero artificial super talent alliance chandling chili circle dynamic ens flare hyera hyperlink katana ledger nora open the sea palpus the graph uniswap foundation walres circuit fern gemini hardhat lit privy and saga all of them are giving away a lot of prizes we're going to tell you who won what we have all those numbers and we also have something new we're going to announce at the end of this event today. So hopefully you stay up for the next hour. Okay. Now, this is a hackathon and the goal for this entire weekend was to focus on building things that we're excited about and showing everybody what we built instead of just talking about these ideas.

And all of you did just that. We had 690 hackers and we thought it'd be nice to kind of tell you a little bit about who they are. The most common places where people came from was New York as they should be and then we had San Francisco and Toronto as the second two biggest cities. People also coded the most in Typescript, Python and Solidity this weekend. And I ran these numbers and these three people have been to those many events at ETH global over the last six years.

So Esong has been to 41, Gabriel 35, and Kuran 34. Now the cool part about all this was I was like, did we actually do these many? Well, yes, but when we kind of started doing async events, people started participating from all over the world and we did anywhere from 10 to 20 a year. So, just in three years, people kind of stacked up on so many of these things. And the most interesting part is that for you and Kuran, the ratio of async to in person is like three versus well, that number minus three.

Um, everything was online. And this is like just an amazing way to see and show that you can actually meet the community that you've been working with online in person and use these weekends to get to know people you've been working with. So, not only did 690 hackers basically hung out with each other, they also submitted 275 projects. I mean, this is awesome. Such an amazingly round number.

It almost feels fake. And we thought we'd do some more things about this, too. So, we looked at some stats on the 275 submissions and DeFi and payments are the two biggest categories of what you're going to see from this whole event. AI being the third one. Flow, CDP, and dynamic were the most used integrations from all the projects.

And the most amount of deployments happened on Ethereum mainet base and flow. So I personally am surprised that mainet is the top of the list but that means we're actually starting to use mainet for things and uh this is an amazing trend. So give yourselves a massive round of applause. 275 projects and uh this is the thing I want to do is also thank our judges who took actually five hours this morning to talk to everybody. So, massive shout out to Alex, Antto, Brentley, Debbie, Gabriel, Jason, Mueale, Megan, Matt, Kaido, Josh, Sean, Nicholas, Shafu, Shane, Siobhan, and Victor.

Okay, 275 projects, submissions were due at 9:00 a.m. They worked on everything they could, and then they went to get their projects judged by those 18 judges. And from this, we have 10 finalist teams. We're going to bring these 10 teams on and they're going to demo what they built and show all of you live and then we're going to talk about all the prizes.

So, for the first time ever, please join me in congratulating and welcoming our 10 finalists for ETH Global New York 2025. Swap Pay, Pumpkin Spice Latte, Noah, Hardat 3 Lisure, Kim Pay, 402 Flash, Primer, TX Insurance Rival, and Pika Vaults. These 10 teams are going to come on. They're going to demo what they built. backtoback 10 demos and then we go into all the prizes.

And this is a list of every project that was submitted this weekend. Usually I have to get out of the shots here. So I'm going to crouch a little bit so you can take a photo. 275 teams here. I just want to point out that just because you were not one of these 10 teams does not mean you were not good enough or something was wrong.

Those 10 teams are what our judges thought were really cool projects that all of you should see. But all of you took the entire weekend to build something that you were excited about and things that you wanted to show off to the people you care about. And uh you should be proud of that. Just there's so many people who are going to win prizes from this list. And uh I am just constantly amazed to see that so many things were built because somebody decided to just do that.

And uh yeah, I honestly I just want to give all of you a big round of applause one more time. So, congratulations to every single person who submitted a project and walked up to a judge to show them and got the feedback. We're going to go into our first set of demos, but two things for people especially on the live stream. Everything here is public. So, you can go on our showcase website on eglobal.

com/showcase and see the list of all 275 projects. And um and before we go into the very first demo, I want to take a quick second to ask everybody, all of you hackers to scan this QR code and fill out the five question feedback form that uh we would like you to tell us about for your experience at this event. There's simple one to 10 rating questions and then one question saying anything else you would like us to know. Uh we do these events every few weeks which means every few weeks a thousand people or more come in and we want to make sure that if we're doing anything that we can improve on we get to imply that apply that immediately and in two weeks have a much better experience for the next thousand people and things that we should not be doing well we want to know that ASAP and things we should continue doing we also want to know that and improve basically the onboarding experience for everybody who attends these events whether it's in person or online I read all of these comments I try to correct a lot of these things myself. Our team spends a whole week implementing these things and we try this again every time.

So, please do this. We're also going to raffle off some of these hoodies for just New York uh for everybody who fills out this uh feedback. And this just saves us time and gives us the feedback to know where we should be spending most of our time. Enough talking for me. We're going to get ready with our very first demo.

So, please give a massive round of applause to our first finalist team, X42 Flash. Welcome on stage. [Applause] [Music] [Applause]

Can you hear me?

Give me a big shout if you've had a very fun weekend. [Applause] So our project X42 flash is an extension of Coinbase's X42 standard for microp payments. The way it works is by asynchronizing the communication between the client and the server. And the purpose of this is to annihilate the settlement latency for the standard. And I don't want to keep on boring you with all this theory.

So I'll hand over to Kel. He'll show you some fun demos. Hello guys. I'm Kel and I'm going to show you guys a basic demo. So basically I've set up a local server that is basically doing like a hello world on my computers and I'm going to first call with the standard X42 then I will try to call it with our X42 flash.

Okay. So before that I want to meanwhile explain the whole technical architecture. So when user is is calling the server with the normal X42 he needs the server needs to wait for the transaction to be settled on the blockchain in order to send the request back. That's like a normal way. So first we have we have to test that for now.

So so actually we are right now using base and base blockchain confirmation time is pretty unstable. So right now it's 200 milliseconds. Now it I I'll try to call it without X42 flash. The way it works is first when when the client need to call the server for the first time using S42 flash. The client needs to uh allow the settlement contract which we built to allow it it to do token transfer and it will top up it to the escro account in the settlement contract.

Then after that the client and the server can just do the uh request and respond directly without worrying about the uh blockchain confirmation time and the sero the client and serve get is proportional to the amount the client stake in the escro account. Okay. So now let's try actually I'll pull up our basic front end to show you guys. So right now I've sp I have to stake a huge amount of money to get this amount of super performance. Okay.

So uh yeah so right now it's only like 100 milliseconds. Okay. So that's like a huge a huge difference between these two different data schema with the same X42 standards. And yeah that's basically that's basically it. And if the client don't have enough money to pay for the server, then the server can just get the money from the escro account.

That's basically how it works. Okay, so that demo was very impressive. It was like 20 times faster with our extension than the normal XR2 standard. 20 times I guess that's like the difference between the speed of a snail and using bolt. So what we want to show you is the request flow and how all the data gets transferred.

So Kel, do you want to show that?

Yeah, I basically said it, but yeah, it's basically we just use the answer accounts to ensure that the server the the server will always get paid no matter whether client has enough funds or not. That's basically like the whole user flow. Yes. Perfect. So we're going to talk about the future implementations of this project.

We are already in the process of writing a white paper so you guys can all read it soon. We're going to implement crosschain probably with something like uh USDC no I mean circle developer tools as we're already using their pay master and we're going to try to possibly implement cool staking tech to implement a new business model and before we finish just wanted to tell you we were actually four people but two had to leave for the airport about 5 minutes ago. So, can I have a big clap for Sean and Jonathan? [Music] [Applause]

Then just finally I wanted to show you the tech stack. So, we used a lot of different CDP tools. We also use Pay Master as I said. We also used for our web two expressjs next some usual tools and this is us on Twitter. Thank you.

Yeah, amazing. I love hacks that actually just extend an existing standard and just improve things. And this is a pretty amazing 20x improvement on on 402 payments. So, I hope that uh this becomes as a real thing. And why would I want 200 millisecond latency?

Okay, on to our second demo. And for this one, let's bring on Hardat 3 Ledger. Please give them a big round of applause. [Applause]

Uh hey everyone, I'm Eric

and I'm Andrew

and uh uh we're all from Waterlue. Go Waterlue. And we're also hard hat users. Um so we like um building uh using hard hat uh deploy smart contracts and most recently uh hard hat made an upgrade from hard hat 2 to hard hat 3 which added a lot of capabilities uh like solidity testing and multi-chain support. Um but we're also uh big on security as well.

So, we want to be able to use uh like uh physical uh wallets and we don't want to be uh like putting in our private keys in uh config files and everything. So, unfortunately uh when hard hat migrated to hard hat 3 uh uh they uh did not migrate some of the support with uh the integration to uh ledger or other hardware wallets. Uh so this is a gap uh that we saw and what we implemented at this hackathon.

Yes. Uh so I will continue to do the demo of our project uh to begin with. So what we're going to do is we are going to deploy just a very simple contract the very default counter contract onto hardhead network but we are going to use ledger to sign the transaction deployment transaction. As Eric said, the hard hat 3 deprecated the library uh primarily because the ledger team has made a lot of advancements in this field and uh they deprecated the old ledger library in favor of a new one. So we are integrating the new ledger DMK developer man device management kit to into the hard hat so that any developer can securely deploy their smart contracts.

So this example is going to just uh deploy the counter contract and afterwards it's going to send another transaction. It's going to increment it by five. Uh I'm pretty sure uh we the hardhead is using VM for this. The previous version was using ethers.js.

Uh I'm going to quickly unlock my ledger because I don't want my password to be seen uh on stage uh obviously. And I'm also want to open the video video feed so that you can see on you can see the ledger in real time. So first thing we are going to uh start the hardhead node. Great. Afterwards I would like to fund my ledger.

Uh so I'm going to fund my ledger to uh with this simple script that's going to send a transaction that uh that basically funds for the gas fees. Right? Afterwards we can just run run the hardhead ignition script that will deploy that transaction. Deploy the contract. Our contracts get compiled and uh as you can see we have we have this blind signing notice because we are signing a transaction blind.

We continue we sign a transaction fully. Right afterwards we're getting another one. The second transaction is going to increment the counter. We sign it as well on the ledger. Great.

So the contract has been deployed and uh we made a simple call to increment the number in the contract. Um that's pretty much it. Our project the we will be uh this basically is somewhat different of a regular hackathon project because it's more of an open source contribution rather than like an actual project. But uh

that's it.

Yeah. [Applause] All right. Another simple useful hack. And the best part of this thing is that they just solved the problem for themselves which ends up helping everybody else who's trying to deploy contracts using hard hat. So give him another round of applause.

All right, we are ready for our third finalist demo. So let's give a massive shout out to Noah. That's the team, not his name.

Hey guys, this is Noah or we are Noah. This is Alexander. I am Julian. And really we are trying to address one of the problems that has been probably the most spe about uh with regard to consumer applications in crypto for years which is the issues that come when either you use you lose access to your hardware or otherwise you know bad things like happen like death. Um obviously your beneficiaries have no access to your crypto unless you've given them somehow your keys or your secret word somewhere which for many of you is likely impossible depending on how old or how young your family members are.

And really solving this has only turned to MPC wallets in the past. And we're looking to provide a solution that not only provides an easy accessibility for recovery of funds within crypto, but also rails to then take funds, off-ramp them, and provide really what would be traditional rails for the inheritance of cryptocurrency, but through bank accounts. as a quicker tech TLDDR. Really the core of it is we've built dead man switch technology combined with a variety of different liquidation methodologies to effectively one identify when a user has died by you know if they have not sent a ping to a server for a certain amount of time you just assume that they have passed or otherwise don't have access and then in addition to that providing again quite complicated methodology and utilizing a number of sources of pricing etc to ensure liquidations are performed effectively and funds are then sent to beneficiaries in effective manner. So, as a quick demo, the first thing you're really going to do is obviously it's Noah.

We set up your arc. At that point, you can determine whether you'd like to, you know, I mean, really, we do cover all ERC 721 uh functionality at this point. But for today, we were just doing ENS's. So, easy enough to transfer your ENS. I own Traversa.

dev oreth. I'd love my kids to have that. um more applicable for most just token addresses. So we set up a beneficiary. This is Vitalic.

Um you could load whatever own tokens you have, but today we're just using a mock token in our tests. First you have to give the contract approvals after which you have a few options. um you can offramp directly to USDC or PYUSD. In these two cases, the beneficiary that you've put above will be the beneficiary that actually will receive the tokens at the end of the liquidation process. However, alternatively, if your relatives don't want to touch your wallets or have no idea how this works, what you want is the ability to off-ramp your crypto in the eventuality that these funds are liquidated.

And to do that, we use firm. Um so, obviously, we didn't do KYC over the weekend. That's a little bit out of scope, but we created a kind of mock process for KYC. You first create your customer ID. With that, you create a payment account.

And from there, you can kind of store these until you actually need to make the withdrawal. Um, from there, you then you get a quote. And putting all these three into Fern, they actually give you an address that you can send funds to, which will then transfer them into a bank account that you've already designated. So the customer has already set this funds up and upon that you can actually then automatically guarantee everything's liquidated to that bank account and from there our assumption is or really just we would assume anyone would want is access through traditional legal processes. The bank accounts transferred to the beneficiaries in the same way that any bank account ever would be and any user can always guarantee regardless what happens to them um or their private keys their funds are safe.

Uh and obviously again this has been harped about for forever. Vitalic has written articles about it that go back five, six years even at this point. Uh, and it's just something I feel that really needed to be taken care of. So, what we're going to do is just use this and let's say a Dutch auction and we're going to build our arc. Now, we have a watcher going that's going to be watching the arc be built.

It should happen in a moment whenever the transaction goes through. And uh after that you have the ability for let's assume it goes through in one moment. So is having some troubles. There it is. So transaction goes through.

We've mocked a bunch of tokens, sent them out and in a moment you should see a method called flood called which is what happens when the deadline has passed and we provide a small incentive me incentive for third parties to come in and activate this infrastructure. We take no fees and everything should be able to be automatically run and through a single singleton contract without any further in intervention in the future. Um so again in another moment here there should be a flood method called after which you'll see an an auction begun and funds liquidated. Um, I'm not gonna make you guys wait for the whole process again. Oh, I actually forgot to set it correctly up here, but that's fine.

Deadline passes and funds are liquidated. Um, after that, you can go and take a look at your arc through management. Obviously, you need to ping it, make sure nothing goes wrong, change things, update them, and also most importantly, just take a quick look at them. Um, in this case, again, we set up a Dutch auction for USDC. I set a too long duration, so that's not actually maturing for a few more days here.

Um, but that's fine. And realistically, I'm just happy to, you know, be able to get the guarantee that should I lose my wallet, which I have before, a month from now, these funds will be guaranteed to be sent to another beneficiary, either onchain, I've decided, or to my bank account. Um, and really I I think that's the core of it. we've used quite a few integrations in in the process and uh really I think you know we're just looking forward to questions from anybody so if there's any interest or questions please come and reach out to us thank you another super cool useful utility and the part that I like about this is that they ended up integrating with with fiat so you actually can just transfer directly to your bank account from stable coins all right demo number four. Please give a massive round of applause to Pumpkin Spice Latte.

[Applause]

Hello everybody. I'm Peter. We are here to bring you some Defi Spice. And these are my friends.

Hey, I'm Seth.

I'm Denny.

And I'm Gilad.

And this is Pumpkin Spice Latte. So, what we're doing here today is building prized link savings accounts as a D5 primitive. Just show up with any ERC 4626 compatible yield source, whether that be Morpho on Katana, whether that be kinetic on Flare or any other yield source, and also bring a source of randomness, which can be chain link, VRF, or anything else as long as it's secure. And from that, you can create a prize link savings account. But what are those priced link savings accounts?

You know, why do we bother with pumpkin spice? We could have just gotten a uh iced Americano like a regular person. Well, there's a problem in DeFi. 3 to 5% is what you can really expect for blue chip collateralized assets on DeFi. This isn't really exciting if your friend is making 100x on some random meme coin in their mom's basement.

Um, but usually DeFi protocols try to solve this by upping the risk. Whether that's sketchy collateral, more leverage, or any other Ponziike mechanism, a lot of these things cause a massive downside. Instead, we propose prize link savings accounts that take 3 to 5% yields and make them exciting by harvesting part of that yield into a prize pot that can get awarded out like in a lottery. So, this allows users to have some excitement on the upside without taking on additional credit risk. I'd like to hand it over to Golad for a demo.

Hello. So, this is Pumpkin Spice Latte. We're mobile first, so this is a mobile uh website. I've already deposited a dollar and a penny into the pumpkin spice pool on Flare Testnet, and there's already $41 USDC in this pool. Now, what I can do is deposit another $99.

Let's do it. That's going to pop open MetaMask. I'm going to confirm that. And then for the approval, and then for the execution, going to do another confirmation. Once that goes through, my balance is going to be updated and that's going to trickle down into the uh a DeFi vault under the hood and that's going to start acrewing uh yield which is going to be part of the lottery.

So you can already see we got 500 USDC now in the pool. There's already been uh fraction of a penny already in the yield and uh of course the principal you can see there. And so now it's time to try our luck. So, we've built a uh mechanic in which the probability of a winning lottery ticket occurring increases incrementally over time. And so, since it's been a minute uh quite a minute since the last drawing, uh it's at 100%.

So, I'm going to press try my luck, confirm that transaction, and we're going to see that I'm going to be the winner. I the probability has went back down to 0%. Uh, and if we're lucky, we're going to see uh the prize pools back at zero and we're going to see me as a lottery winner in the history here. Uh, and then once I'm done with the prize, uh, pumpkin spice latte prize pool, of course, I can withdraw my uh, USDC. So, I can just do 55 here for example, confirm the withdrawal and press confirm and my balance will be decremented.

talk about the future.

Yeah, in the future uh we hope to modularize this further and uh essentially you can think about it as a framework and this framework can be applied uh to add incentives to your DeFi uh protocol. And so we envision this as sort of going on top kind of like add some pumpkin spice just kind of on top of the protocol and uh incentivize uh behaviors but also sort of look uh to more consumer focused uh DeFi experiences.

All right. Well, that's it. Thank you very much for your time today.

Thank you.

Awesome. Another simple, useful, and ready to go DeFi app. All right, on to our next finalist. Please give a massive round of applause to Kaape. [Applause] Hello.

Hello. Wow, this is loud. Cool. Awesome. Sweet.

Good afternoon. We're team Kim. My name is Derek. This is Vivian, Jason, and Dan. Uh today we're going to show you guys what we built.

uh but I'm going to first talk about why we built it. Uh so I don't think there's any question around how the future is one with many stable coins. Uh with US regulatory clarity now more and more companies coming onchain and trfy building stable coins u the inevitable uh future of stable coins is near. However we believe that there's still fragmented liquidity and problems with stable coins. If we look at pool or curve, I mean uh there are many USDC, USDT, DI stable coin pools all fragmented into many many uh chains uh and obviously pools.

Unis swap is no different. As you can tell, there are many USDC and uh token pairs with other uh stables. And so today we present our implementation of orbital an AMM focused uh or specifically on stables designed and proposed by a paradigm. Our implementation basically takes the concept of a constant product unis swap pool and brings it into higher dimensions so that this stable coin or this liquidity pool a single liquidity pool can support three four hundreds thousands of stable coins all from a single pool. The advantage of this is incredibly low slippage, incredibly capital efficient swaps and obviously uh if you build the the cross-chain components of it, this solves the unified or the fragmented liquidity problem.

Uh so this is obviously really cool, but what would be even cooler is if we applied this to real life. And so today we present uh Ka Pay. This is actually a Stripe alternative uh for merchants looking to accept stable coin payments. The reason this is a Stripe alternative is because we can charge 10 times less than what Stripe does today, supporting more stables and more chains. This is a really brief architecture overview of how it looks.

The merchant can specify the stable coin that they want to accept. Any stable coin will work and the customer can pay with any stable coin that they wish. Kima will do this crosschain swap under the hood for them and they will leverage liquidity providers to offer the rock bottom fees that we can charge our customers undercutting Stripe entirely. and let's do a demo now. Awesome.

So, let's assume that you are looking for a article and the merchant has employed uh our product to accept stable coins. As a merchant, they can specify what stables that they want to accept. And as a user, I don't need to worry about what stable coin or what chain they're on. Uh but for the purposes of this demo, we're going to write or we're going to display that information. Uh, so when I click on this this article on the top left, I see that this is a paid article.

And when I click this, we're actually going to use Coinbase's uh 402 protocol under the hood to make a payment required response. Um, and so that triggers this this what you see here. What I'm going to do is I'm going to log in using Coinbase embedded wallets. I'm going to type in my email. All right.

I'm going to get my onetime passcode. Perfect. Okay. So, I'm going to verify. Awesome.

Okay. So, we can see that my wallet already has a bunch of stables in it. And normally in production, we would just see that this article costs $1. We wouldn't specify the chain or the token, but for the purposes of this demo, we've made that very clear. So, I'm going to swap I'm going to pay for this with USDT.

And uh when you're paying with uh tokens or stables specifically and you're doing these crosschain swaps uh you would expect some type of slippage. But for stable coins any type of slippage on a US dollar peg token just doesn't make sense. And this is why we employed orbital under the hood. So by continuing I can confirm this payment and execute this swap. There's this hash here I can type into base scan.

I'm going to let it actually complete first. Awesome. So, what it did was it uses Coinbases 402 protocol to verify and settle the payment. Uh, and then obviously when the payment is verified, it will return a 200 to the user and we will expose the previously paid article now uh to to the user. And if I put this on base scan, we'll see that it actually executed the swap.

Obviously, if I go to this contract, we'll see the orbital pool that we used and all the complex math there. Um but for the purposes of this demo u we don't have time for that. Um yeah that's pretty much it. Uh if you're curious on how we implemented orbital all the math is here in term you know the ticks and uh yeah thank you very much amazing that was such a smooth demo and they actually implemented and integrated the orbital exchange the AMM which is specifically for specifically designed for stable coins. more production use cases of things we want to use day-to-day.

Okay, we are ready for our next demo. And for this one, I'd like to bring on team primer. Please give them a big round of applause. [Applause]

All right. Hi everyone. I'm Cynthia. I'm a rising sophomore at Stanford.

Hi, I'm Aaron. I'm a rising sophomore at UC Berkeley.

Hi, I'm Rishab. I'm a rising junior at Cornell. And this weekend we built Primer. It's a checkout feature on Amazon that allows for seamless crypto payments. We chose Amazon specifically because we think there's a huge TAM.

Everyone who uses crypto most likely has either heard of Amazon or uses it. There is significant overlap between the two. We had to reverse engineer some things because Amazon every time we refresh there's a new idea of login every single time. So it was a technical challenge but this is what we imagine the future of UX to look like. So really excited to talk about it.

Absolutely. So, we think it's a huge game changer because now our Chrome extension basically allows you to buy pretty much anything on Amazon with stable coin or other cryptocurrencies. And our project also came from a personal viewpoint because we kind of don't believe that the world can move into web 3 where the largest e-commerce platform still cannot accept digital assets or cryptocurrency as a form of payment. But yeah, let's dive right into the demo.

Cool. So, I'm just going to start out with the regular Amazon page. And Erin, what do you want to buy today? I a hair tie cuz I need a haircut in the city.

All right, let's search for hair ties. There's a lot of them. I'm just going to add it to the cart. As a reminder, this is what the normal Amazon UX looks like. We haven't really implemented anything yet.

I'm just going to proceed to checkout. As you can see, it's very normal. Use this payment method. And over here, you see place your order. We put primer into a Chrome extension format on the using Chrome developer tools because we think this is the best way for like easy installation and the best way to adapt to both mainstream and crypto users.

So I can just load unpacked and I'm just loading Primer into here. As you can see it's over here with my other extensions. I love these games by the way. But when I refresh this page, you'll notice something interesting. We have a checkout with cryptobuds in here like directly injected into Amazon's page.

And that's entirely on purpose. We wanted the design to be as seamless as possible. Almost like Amazon implement this feature themselves because this is really how you're able to win more users onto your platform and how you have like great user retention. So I guess if I press check out with crypto um the extension modal opens up item breakdown total. You can select a wallet.

I'm just selecting Coinbase wallet right now. I press proceed to payment and a new model opens up on a new tab. Again it has items breakdown. It has my current wallet connected to it because I demoed it previously. But if I disconnect right now, um you can see that the wallet sender address is not connected because my user I'm like the customer.

I haven't connected my wallet. However, there's an Amazon receiver address. This is just an arbitrary merchant wallet that we are using. Amazon listing price, etc. So, I'm just going to connect to my wallet right now.

Very simple flow, very pretty. And then the button has changed to like what I need to pay. I click again. Um, it gives me the asset changes. I press continue or confirm, it processes for a little bit and then it goes to this page which is which is a very simple congratulations page.

Right? So, as you can see here, if we go into the base scanner, you can see that the transaction was actually happening over the base mainet with actual USDC money. Um, this is Cynthia's address and this is our merchant uh wallet address where all the transaction will flow in. Uh, you can see here the gas fee is pretty negligible. Will happen around like what 2 seconds.

So pretty fast in my opinion. Um, and this is just a little sneaky behind the scene. And all the UI were also designed by us because we think web UI and UIUIX is really critical uh part of web 3 and we want to try to on board web two users like my mom who uses Amazon regularly. Yeah. So if I press go back to Amazon, I'm just going to also show you what payment looks like.

We do it with a very innovative bridge because we like we decided to use like automated gift cards. we don't have access to like Amazon's um incentives API and all that because that's out of scope for like 36 hours. So our workaround is actually using gift cards. And if I load the payment method, you see here right now we have no available balance in our gift card. I guess if I press check out crypto again and then complete checkout, it puts the gift card code automatically in here.

Press this apply. And then now I can just use this new payment method. As you can see, we didn't use any credit cards. There's no like balances being taken from like anything too centralized. It's just a gift card already applied to your account.

So, if I press like place order here, it actually works on Amazon um order to place. Thanks. I'm going to turn this off to avoid notifications happening when we're testing. But when we go back to the normal Amazon web 2 user flow, it still shows up. And what's really interesting is that the total is $0.

0. This is because we didn't use any of our credit cards to make the purchase arbitrarily. It truly was that gift card code that we were able to generate apply automatically. Um, and this is like basically how our uh basically how our demo works in terms of like actually automating it. We had to like pull the elements from the Amazon page every single time and figure out a way to standardize it because again we had to refresh and the ID changes.

But this is just what we imagined for this project. Yeah, in the back end we're using CDP data API to allow for payments. When the merchant address receives some transaction, then we would initiate a gift card purchase for that payment. Thank you.

Amazing. A true definition of a hack and a live demo. This is awesome. All right, four more demos to go. Let's welcome Transaction Delay Insurance.

[Applause]

Hi, I'm Jordan. It must be my lucky shirt that I score on home terrain. So, transaction delay insurance. Um, transactions can be delayed on any blockchain. Doesn't matter how fast the blockchain is, there's always a load that can break it, delay it.

And uh blockchains like Zirket even quarantine transactions that may be suspicious, but uh it's a scary thing. So I provide insurance against it. And this is really an alternative against EI alternative to EIP1559 uh where you pay extra to get your transactions to execute faster. So uh in this if I have an insurance again I have multiple policies uh that ensure different kinds of delays different kinds of amounts of money and uh how this works is a simple RPC proxy. I I send the transactions to my RPC proxy.

It's fully transparent. Sends all the transactions to the blockchain RPC and back except for two calls. One call is when the transaction is broadcast, I attach the current block number to it and I sign it. And then on the way back when it gets confirmed, it also gets signed. So those those two signatures can be uh ECDSA recovered in a smart contract to prove that a payout should be made to the claimer.

So um what it does I already explained but uh uh the insurance the the insurance con contracts take care of policy factory policy creation purchasing and claims and the economics is tremendous. And why is it tremendous? Because if you try to buy a co a car insurance, one insurer will quote you 2,000 bucks and the other one will quote you 600 bucks and you don't know why the difference. But really the prices are so soft that you can uh you can make a lot and nobody complains about it. I even have a user interface we can which I can show now.

uh uh thanks to AI vibe coding I managed to even uh get uh a UI. So that's that's one. It's really not instrumental because everything can be done uh programmatically. But here are some policies and uh I can an administrator can create a policy. I will name it, comment something.

I'm gonna make uh 20 blocks delay pay out something. Uh create a I create the policy and uh it will create a policy and then anyone can purchase a policy and these are my policies. This is my new policy but I'll go into this standard policy that I know about um um and I can purchase insurance myself uh from this policy. I can purchase policy actually and this is my policy. Okay, I I have insurance and uh it it'll take a short time.

Yeah, it's here. So then I can send a sample transaction and hopefully I luck out that it's delayed. Uh don't hope too much. It's unlikely. Uh that's why insurers make a lot of money, but let's try.

Uh oops see let me see. Yes that was a race condition that I have to fix. So this is my uh transaction. All I have to do is remember the TX ID so I can claim the delay here. transaction was submitted, intercepted by the proxy and uh let me claim let me claim uh uh uh let me claim claim.

Sorry about this race condition but uh h they select ah I select a policy of course I select a policy here's my transaction and let oh yeah of course it's uh it's zirkus proof they're too fast it's fault they're too fast anyway uh I I can't fake this because I have to try many many times But I do have all the tests that pass and I can show uh uh all possible conditions uh that I handled uh by delays, non-delays, policy, not enough money, etc., etc. Uh so that's it. Uh we can [Applause] Awesome. Thanks, Jordan.

Didn't imagine buying gas futures for transactions. Nice. Three more demos to go. Let's give a big round of applause to Swap Pay. [Applause]

Hello everyone. We are Christian Santiago and Julio and we are from Colombia and we built swep swap pay. So let me go to okay so what's going on there? Okay appreciate. So, Flap pay with any token mix seamlessly.

We've been in the situation that we want to buy an asset in web three and we have the funds but we have it spread it into different assets and we don't have the sad that amount in exact asset that the merchant is asking us to pay. So we find ourselves paying uh swapping different tokens, clicking for approvals and having transactions fails. And this shouldn't be like that. We could do that with a simple interface. And this is why we built Swap.

Uh yes, let me go here. We built an SDK that allows checkouts in Web 3 effortless. Uh we give the opportunity to developers to receive the token they want to receive, allow the user to pay with the multiple tokens that they have and do that in just one transaction. So let me show you how it goes. This is our interface.

Uh the NFT is just an use case. So we connect the wallet. Then it shows us all the assets that we have and the amount that we have. And it uses chain link data fits to show the real PL the the price in real time. and we start choosing the different assets that we want to use to buy this NFT, this $52,000 NFT with the different assets that we have in our wallet until we complete the total allocation.

So we go and purchase the metamas shows us that we are going to do these approvals or all these tokens and that we are going to send this those tokens and that we are going to receive an asset and we confirm. We just wait for the blockchain to go and it is done. We made one single transaction that we made five swaps and acquired a single NFT. We uh under the hood we use the EIP5792 to batch transactions and B the transactions, the approvals and everything that goes uh through to do that transaction. And we can see here in the ether scan that we have uh all those um uh different uh movements that we just made with this single click.

Uh we also uh bought uh PayPal USD leave it there. We used the PayPal USD uh to buy the NFT and we gave it a small leverage of 1% so to allow the transaction to go through and the remnant that is going to uh to keep uh after the transaction is going to stay on the wallet of the user. So um uh it's uh this is just one single use case that we can have with swap pay. There are different options that we might look into the future. Now we are going to add the NFT to the wallet and with that we are going to complete the whole process.

The project is live on sepoleia and that's all. Thank you so much. [Applause] Amazing. It's live. All right, two more demos to go.

So, without further ado, let's bring on our second last finalist team, Rivals. [Applause]

Yo, what's up, Eth Global? We are the Rivals team. I'm Zach. This is Chris. This is Sydney.

Um, and Rivals is an augmented reality uh realtime um FPS shooter. Um, and we're just going to dive in and give you a quick demo. So, um, this is how you spawn in. Um, the mines are set, the mobs are hungry. Beyond the screen, every tap is a countdown.

Enter if you dare, losers leave lighter. So, you spawn in and you've got a bunch of zombies in front of you. If you uh tap the screen and and look at them, you can shoot them. Um and uh yeah, each bullet does one damage. The zombies have about 10 damage each.

And um yeah, they've got a um this is uh the AR is tracking the floor here. Um if you can see towards the bottom of the screen, there's like some dots. Um, so this maps out the the floor, the walls, the the whole environment. Um, and yeah, as you can see, it's it's kind of dangerous. Um, but uh yeah, the the zombies have a um a path finding, so they'll follow over all the surfaces.

And as you can see here, these are um traps. So this is the second half of the the whole game. Um, the idea is you fight the zombies and you get rival tokens. Um, and you can see those at the top of the screen. Um, oh, it looks like looks like we're on the local test net instead of the flow test net.

But if we were on, yeah, flow test net. Yeah, we can see three rival up there at the top. Um, and placing each one of these mines is going to consume one of those. Um, and if we were doing a multiplayer demo, um, I could come in from the other end of the stage. It's kind of hard because it's like based on GPS coordinates.

Um, so it's it wouldn't really work very well indoors potentially, but that's something that we would love to explore. Um, doing better like using Wi-Fi hotspots to to better triangulate your positions. But um, uh, yeah, like yeah, so the the tokconomics of it is is kind of interesting. So you kill the zombies to kind of bootstrap your rival tokens and then you place the traps using tokens as well. Um and so rather than um you losing your tokens to the zombies, you lose them to other players that are playing.

Um yeah, I mean there's anything else on like the demo we can show. Um so these are these should be running live on flow. Um, as you can see, 55 seconds ago. Um, and then, uh, this is our contract live and verified on Flow Testnet. Um, these are it's just kind of basic things that we're doing here.

Um, so if you die by a trap or you die by a monster, there's kind of slightly different behavior here on where the tokens get transferred to. Um, and then if you kill the monster, that's kind of the main way that that tokens get minted. Um, and if you spend it on a mine, um, it it burns the token. So, very simple. Um, this part's all on chain, the the token aspect.

Um, and it's updating in real time. Um, there's no there's no transaction uh there's no like transaction confirmation or anything. Um, you take it over.

Yeah, sure. Um, yeah, just to speak to this a little bit more, um, yeah, our server endpoint just manages a private key, so the user does not have to worry about gas or anything like that. We've implemented these custom uh mint functions where when any in-game actions happen um there's a call to the game server which then uh manages the token balance uh mapping for the user. Um so you can actually see these calls coming in in real time as we were doing that. And then if we were to actually go over to the database here, you can actually see um here is all of the mines that we placed.

So, um, with the app, again, it's not just, um, fighting monsters, but the whole point is you're kind of in this apocalyptic world where, um, it's kind of this real time, um, competitive game against everybody in the world. You can kind of imagine it like you're walking down the street, you get a notification on your phone, you just stepped on a mine, you have 5 seconds to get out of the blast radius or you're going to die. And so, um, if another player eliminates you, uh, just to reiterate, they get to take 20% of your stake. And then we also have a burn mechanism so that if you are killed by a monster, we actually burn 20% of what's in your wallet um, in the game. And then it's a full uh, Unity app, fully crossplatform.

Um, and I just want to shout out for any web 3 game developers out there, please check out Miximo. It's a product by Adobe. It's really great for quickly rigging models and getting demos like this um set up. We pulled a lot of late nights doing this, but this like immensely helped us. Um so big shout out to Miximo and thank you.

Awesome. That was such a fun realtime game demo. Okay, we are ready for our 10th and last demo for the finalist. So, let's give a massive welcome to Pika Vault.

Hello everyone. I'm Adair and this is Al and we are Pika Vault. So, uh, Pika Vault is a multi-chain vault that allows for both depositing, withdrawing, and holding of assets across multiple different chains. So, as more institutions come and enter crypto, um, there actually becomes a problem. We're going to have more and more application specific chains like Ono Finance or Plume for RWAS.

Um, and more and more institutions who want to put together assets that exist on these chains. So here we have Black Rockck Bidd, we have Onondo's S&P 500 fund and Plume Gold and Coinbase BTC to form Pika. But if you try to do this right now using existing D5 primitives, users are stuck with using multiple wallets, bridges, and gas across different chains, institutions currently lack the ability to custody these assets using their qualified custodians. uh because a lot of these assets when they're implemented they become wrapped and are therefore synthetic non-native assets. Um and for protocols this means that the liquidity is really fragmented across chains leading to poor UX and there's opaque risk from those synthetic asset providers.

So what Pika does is it gives you one vault that uh is able to issue shares issue and redeem shares um across multiple vaults on different chains. So the hub vault uh handles shares. Uh the spoke vaults handles deposits, redeems. Um anyone can deposit USDC on one of these spokes um and have the hub actually manage that um manage those share process requests. So the depositing of USDC is done via CCTP.

Um the allocation of the funds is processed using layer zero. Um, and then any positions that are made are also activated using layer zero messaging. Uh, the reason that we use CCTP in addition to layer zero is because when we're trying to access assets like Coinbase, XRP, or like these different assets on other chains, they need native USDC. They can't operate with these synthetic versions of USDC. And when you're placing multi-million dollar transactions, you can't deal with any slippage.

Am I missing anything? All good. Okay. Um the integrations we used were layer zero. We improved upon their existing OmniV standard which only allowed for um purchasing and redeeming shares on multiple chains.

We allow for holding positions across multiple chains. Um we use CircleCTP Coinbase for the embedded wallets uh and better experience and then chain link of course for net asset value calculation and nav pushing. So let's do a demo. Actually you did. So we have two parts demo.

One is uh front end. What was the Yeah. Yeah. You log in with your email. Coinbase manage wallet.

You don't need anything. You just enter your email and then you will receive a code and that's really it to uh start using the uh platform. Your uh wallet is already generated here and we just uh built a demo for you to see. Here you can see uh from any share. This is kind of weird because like I always expect the MetaMask or something else to pop up.

But uh no, it's just uh feels like a very polished user interface, web user interface. It's just done. And yeah, I deposited vault and actually received my shares. So uh that was it for the deposit. Uh for the redeem flow it's a little bit uh involved.

Uh it's there is something missing on the front end but uh I will show you sorry I will show you uh here a flow uh so you can deposit from uh base. Let's say this is all happening on chain. Uh now I am depositing $1 USD dollar to the hub uh on base Sepia and uh I am going to send this uh crosschain uh yes from base I'm sending those shares to uh Sapolia uh from base Sepia to Ethereum Sapolia that sorry uh now I have probably do have those shares or I don't know maybe I don't but let's see right now I am doing uh a request redeem from Sepia from Ethereum Sepia to base Sepia. So this transaction takes a little bit uh long like one one or two. Oh, okay.

Nice. Uh so now I have uh some claimable redeem and pending redeem. So, if I uh do just a second. Yeah, I need to send this claim redeem and then uh this would result on multiple transactions. But we can see uh probably layer zero transaction.

Uh hopefully. Oh, okay. I need to sorry uh I missed the point. So the whole point of uh asynchronous redemptions is like uh someone uh has to approve those uh shares like redemptions. Uh so I have to approve uh those redemption requests as a manager.

Uh after that uh they will be available actually. Yeah. Mark claimables. So I I am as an admin uh that there is not much uh claimable funds but since this is a crosschain transaction I mean uh there is an example on top of the uh here uh so basically after uh manager uh approves those uh claimable pending request then the user can uh finalize ize their redemption requests crosschain and they can choose where to receive their funds like their USDC. They can choose to have it on base Sepia or like uh Ethereum Sepia or any other chain.

Uh and uh it just works all through the hub chain. Uh doesn't matter uh which chain you are, you can uh both send and receive to any chain that is the hub connected to. Okay.

So, last thing I'll leave you with uh is that the presentation had a diagram of exactly like the flow that he just described. Um and so just to clarify exactly what happened, uh we deposited it sent a message to the async composer on the hub. It sent a CCTP message, a layer zero message to the spoke. Um and then when you go to asynchronously redeem um the actual vault manager as he mentioned who's going to be the fund manager is going to um actually request or process those requests on the spokes um and then all of the messages are going to be executed asynchronously through layer zero um fully autonomously on chain. So thank you very much and this is Peter Paul.

Thank you. Amazing. Those were our 10 finalists. So, please join me in thanking all of these 10 teams again. So, massive round of applause to Swap Pay, Noah, Ka, Pay, Primer, Rivals, Pikov, TX, Delay, Insurance, X42, Flash, Hardat 3 Ledger, and Pumpkin Spice Latte.

Wow. The part that excites me the most is that all these things were live and you can just also play with them while they were doing these demos. And uh that's actually the biggest trend for the 275 submissions. more than 40% of them were deployed and uh I want to see more of that and this is absolutely absolutely incredible. Okay, how's the energy in the room?

Oh, this is great. Wow, I am actually surprised. Well, now you have to perform. Okay, we're going to get to all the prizes, but thing I want to talk about is being onchain. uh we want to do more things on chain not just as ETH global but also as a community to show that all the things that we're building here for fun or for profit are actually useful and ready to go and a big part of that what we're doing is the the packs uh everybody who hacked has a hacker pack that gives you access to the faucet and a bunch of other things but after today you'll actually be able to mint a bunch of other packs that come with more perks based on how many events you participated in or the prizes you're going to win today so you get to do anything from getting access to upcoming other events by our partners to higher limits on faucets, things like discounts on security audits and a bunch of other things from all this.

And a bunch a part of that bundle is also ETH global plus which is a way to access everything that's happening in the ETH global ecosystem all across the world. And you have things like obviously Pragma events. We do eim roaming for people going on. We have hotel discounts, hundreds of side events you can go to, the city packs people bought, startup credits that give you access to thousands of dollars of credits to simplify your work. And the thing that I'm super happy about is that just last month we ended up launching and offering access to Priority Pass through Elo Plus.

So all that is now happening on chain. You get to mint this as a global plus member and you get annual membership to party pass free and you can access an airport lounge and this is all happening directly and some of you will be able to use this basically in the next minute and on your way back if you're flying back today. So check that out. All that is on eco global plus eglobal.com/plus.

And let's go to prizes.h here sitting in these front few rows like all the rows has hacked at an inerson hackathon before. Okay, that's like 50%. What about in the last 12 months in person? All right, that's like 20%.

Great. So, most of you then don't know what game I'm about to play and we're going to have some fun with this. So, we have a hundred slides of prizes to go through. And the way we're going to do this is I'm going to talk about which team is going to win a prize for which company. And if you're sitting in the audience and you're that team, I want that team to shout.

And the loudest team across all slides will win a ledger ledger flex. That's the one you saw in the first demo, the good one. But every member on that team is going to win. And if you were a team that ends ends up winning two prizes and you were top of the chart before but didn't shout again, you got overtaken by somebody else and you shout again, you get dethroned. So you're going to have to keep up and there's a penalty for being too good.

So are we ready? You failed the first test. All right. Are we ready?

There we go. We're going to give away $275,000 in prizes. And we're going to start off with Coinbase Developer Platform. All right, I'm going to say this word. Just going to just be very careful here.

Only when you hear your name, you shout. If you see three names and you're one of them, I have no idea who's winning. So only after I say your name, that's when you shout.

So, hopefully we'll see some of these finalists there. And I want to congratulate everybody for winning incredible amounts of prizes and doing so many hundreds of projects. Give yourselves a massive round of applause. All this is on the showcase. The little energy that you have left, I'm going to ask you to reserve that for a one more minute.

And uh the thing I want to talk about is basically everything we said about the prizes, that's not final. So it's like 80% that Chase, but we're going to check a bunch of things before we give them out to you. And that means we have to walk through everybody's source code. We have to make sure that nobody cheated. We have to make sure that if you used AI, you actually properly integrated things and function are being called.

And we'll be doing that over the next 3 weeks. So the amounts may change. Some people may get disqualified. We may have to ask you for more proof. And our deadline and timelines to do all of that is the next 3 weeks.

And the prize will be distributed on September 12th. So prizes as well as your stakes will be returned on the same timeline. And the week before September 12th is when you get an email with all the confirmations for this is the final amount of the prizes and the categories and the totals. And this is where it's going to be sent. And that's where you'll be able to see and receive all the amounts.

Now, this is a part I'm excited about. This is something we've been working on for a couple years now. And uh you know us for doing one thing really well, but we also want to do other things and get really good at that. As much as I'm excited about this, I'm kind of a little bit sad because I would have to contradict a bunch of things that I have to say all the time at ETH Global. So, without stalling, we're going to be doing a massive conference next year as ETH Global and it's going to be one of the biggest events we've ever done.

going to try for more than 5,000 people here and it's going to be all about what's actually happening in Ethereum and who's building with the protocol. How do we actually improve things and how do we actually get everything back to where we would like it to be as stewards of this ecosystem, but also how we get the rest of the world to also care about what we're excited about. Eat is going to happen next June in New York City. [Applause] And I can't wait to say that this is going to be a conference. Everything is live.

We're going to publish the dates by the end of the month on the website directly. ecomf.com, the biggest event for Ethereum in the US next June. So, the last bit of energy that you have left, I'm going to ask you to go all in and thank everybody that helped make this event possible. So, we're going to just keep on clapping and the faster you clap, the faster we'll go through the slides.

So, on three, let's make sure we thank everybody who was part of this whole weekend over the last few months to the last hour. And uh I want to start off with all of you hackers. Give yourselves a massive round of applause. All of our judges, all of our mentors, all of our volunteers, all of our speakers, all of our partners, all of the venue staff, everybody we work with from photographers to videographers to caterers, to anybody involved, to the rest of the ETH global team. A massive shout out to George, Alex, Karen, Aubrey, Val, Pascal, Reach, Safia, Calvin, Maggie, Nuno, Anna, Emily, Jacob, Andrew, and Liam.
