sorted anyway congratulations from Chronicle [Applause] verify all right and finally we have mantle hey what's good let me just pull my telegram cuz crypto runs on telegram um it's just same same order as what we sent it should be cool all right um are you can see it here uh we have no winners cuz there's no winners in crypto we're all we're all winners of crypto we're very decentralized and horizontal so um the uh uh best defi uh split uh winners are goat and multiland so uh this and I'm sorry this is actually incorrect it's 12 $1,250 in MNT so you have to do some math so it's actually at least double double of this so you will will get more money um okay um for Best nft in gaming I have to apologize cuz we actually got quite a few incredible um applications for this one or

names if if you deployed a contract on mantle and you're not on this list I blame it on someone else not me because then we didn't get it in our spreadsheet uh but it's bet 3 goat uh proof of picture multiland reporter uh project craftable TCP sport sport X music VI a Sprint mint split 3 um asset link volatility Vista Aero da fluffy and Legacy link [Music] um every time I'm on stage I think of uh I think of cartic because he does this so well so cartic if you can if you can train us how to speak on stage one day that would be that would be great um yeah uh thank you for the organizers all the volunteers all the hackers all the co-sponsors um let's do it again next year thank you thank you [Music] woo and last but not least request Network these [Applause] [Music] guys hi everyone Hi hi hi t t one to hi um first of all we had 10 amazing projects thank you so much for your work during three days 2 and a half days thank you so much all of those 10 projects I strongly encourage you to check out our grants program you might have a surprise there but let's get on to the show the best project that we received out of these 10 amazing projects uh split three [Applause] congratulations congrats the uh second prize goes to proof of picture thank [Applause] [Music] you and since honestly they were all amazing projects and again it was 10 we were surprised by the amount of projects we have received um we decided to give some honorable mentions in uh Rec tokens which is our native token obviously and they go to uh perer Finance congrats [Music] guys um Starlight coffee invoice 3 and asset link congratulations and thank you for an awesome hackaton experience love you [Applause] all thank you thank you to all the sponsors and right now we can go to E for so Bounty winners and these are can I can I say something just give a short introduction we this was like a Hol day process about uh choosing the best projects uh but we want announced the E4 abantis 2 uh we had a couple of criteria which was uh Innovation value to user and U quality of the code and we also looked for the formalities so some projects had to be rejected because of that but yeah uh but it was really awesome to see all the projects we reviewed all of them and uh it was an awesome experience to see all the videos all your um decks all your infos and really appreciate your work that you've done for this and we chose six winners uh 1,000 bucks each and uh each of you that will be announced here will have a chance to speak at the stage and present your project uh if you're are not present or you don't want to we'll play the video but to submit it so let's go so the first winner is split free [Music] and can I guys invite you to the stage we will present your video and we can let you tell maybe a few words from you the video or yeah the video I mean uh we can play your video you can talk about the project uh or both uh I don't know that you didn't have time to prepare it's a surprise but uh yeah we'll take that into account and this is split Tre in group of friends so if you know split white similar about with crypto and security as Cod principles so let these are my groups where groups of people that I share expenses with so for example my flatmates my friends whatever so let's create a new group just need to give name and the members and let's go with the creation and under the hood we're basically deploying a safe multi wallet for managing everything about a group Okay cool so now our group is created and these are the people that I invited they actually need to join okay so I'm joining here with the other address okay so now all the members joined and so we can go and create a first expans so for example I paid for groceries a paid like three and they paid for everyone needs to share expense so let's create it this is initiating the multi proposal and basically now another person needs to approve the expense to actually put it in the in the balance so I'm approprate with another member of the group nice so now we see our deps so for example this others owes this one this amount and and these are what these addresses Ed okay so now let's pretend we made more expenses and it's time to close the group and settle our apps we can propose the creation of the group also with a multi proposal transaction o home and I'm going to approve it with this other address okay so now it's time to settle our dabs so we can either go and settle our dab by spont L paying what we owe to other people or the the Creditor can create a payment request and this is where we use request Network so under the hood we're actually creating a payment request right now and uh the deor uh is going to see the details of the request and can now say settle depth and the payment is going to be executed cool okay now as we can see our thatt is paid and so good so we can also deposit funds into a common pool for the group and then we mul tose proos we can decide how to use this money maybe for covering common expenses or stuff like that thank you for listening [Applause] bye yeah guys so if you want to just say a few words about the projects the challenges you met the problem you solved this is your moment yeah you want to first of all thank you everyone thank you it wor team for the amazing weekend thank you for the sponsor prizes I think the the main challenges were I don't know just coming up with an idea that we could use on our own and uh it's something that we experienced in all these trips to aadom and conferences so uh let us know if you want to try it and uh exactly next conference that you have to split EXP fens with a group of people or something like that just Bing us and we'll got you covered who wants this in production come on woo thank you again thank you guys congratulations thanks [Applause] [Music] guys all right and the next winner are Dash da all right they're coming ni congrat welome [Applause] congratulations okay so guys do you want to say a few words do you want to play the video y okay hey everyone let me introduce Dash da to make delegations great again this is our team different background one thing in common nobody slept last night now delegations are our only chance to make crypto work the problem is delegation sucks these are very important delegates talking about Sol the issues with delegations here we have the list no standards no tracking no alerts very ghost delegates lack of participation everything sum up into having no idea how your voting power is being used that's why we created dashboard your delegate tracking and alerts system now let me show you how it works you can hear you see all the Dos you are interested in participating you can choose from let's say we go to our friends from Jam here you will see all the most important delegates from jam and if you select the delegate you will see a lot of information this is very relevant to understand what this guy is doing participation rate voies wins and loses but most importantly you can follow the people once you follow a delegate you will have on your own profile all the information of the people you follow and you will get notifications so it won't be just seeing what happened but it will be real time alerts on what the delegate is doing and most importantly isn't doing like is he voting what happened with the last proposal like what is the participation rate you will get notified on everything you need to know to track your delegation participation to do this we deployed smart contracts that are apping followers addresses and delegates all together emitting locks on chain and we read from that to send the notifications using push protocol that's it hope you like it hope we can all make delegations Better Together see you next [Applause] time yeah so um didn't expect to win but like to say thanks for all the sponsors and the the the team for the great venue and and uh yeah so a little bit about our product is um basically we fa this issue where down analytics hasn't really changed over the past two years so uh one pain point is when tokens get delegated you don't know where it goes so that's the narrative we we try to uh improve there and yeah if you guys are interested feel free to contact us to use our product but yeah thank [Music] you congrats [Applause] guys all right guys the next winner is [Music] multiland hey guys come join us at this stage would Youk ladies and gentlemen welcome to the multi-end demo we're crossing borrowing and lending protocol built on mantle and and ding Chronicles for liquidations of seoan the issue with the current lending Market is that as a user you're compli to borrowing from the chain that you supply collat along allowing for isolated positions that damage user experience and usability our solution provides the intro ability that the lending Market needs with cross chain collateral assets on multiland are moved across chain through a node communication layer enabling low fees and decentralization our protocol is chain agnostic and supports any chain Chronicles of launch their price reads on enough talking and let's jump right into the demo let's begin the demo by connecting our wallet and supplying some usdc on sell I'm going to supply 1,000 usdc and click lend I'll be prompted to approve the contract to spend and finally Supply after a few moments it will appear in our positions I'm going to repeat the last steps for mantel and sepolia and I'll be right back with you moments later and we have three separate collateral positions on different chains now let's borrow against our collateral let's start by choosing a chain we want to receive our tokens on and inputting an amounts now let's borrow we will be prompted to confirm the transaction just a few seconds later and we see our barred position on Manel as you can see our collateral onello has went down by 125% of our debts giving us a cloud realization ratio of 80% let's take out another borrow position on suppo by repeating what we've done before now that we've taken out our positions let's take a look at the outbound transaction on cell and the inbound transaction on seio let's go back to our app and try to withdraw our collateral on mantel we'll start by expanding it and clicking the withdraw button we will then confirm the transaction to withdraw and just like that the position has disappeared and we've gained our collateral back similar to how we borrow tokens across chains we can also repay tokens across train however we're more interested in our liquidation engine currently liquidations are only available on sapoia due to our Oracle provider Chronicles limited coverage at this time it's difficult to explain how a liquidation engine works in a short demo but you can view the full source code on our GitHub for the purposes of this demo we modified our liquidation function as we don't have time to wait for usdc to dpeg again let's try and liquidate our collateral on sepolia and just like that our collateral suppo has been liquidated and the lenders have been made whole that concludes our demo we thank you for listening our app is live on testnet and can be visited by the QR code on screen [Music] bye thank you everyone uh thank you to the sponsors thank you for the organizers uh we had a lot of fun the past few days making this product uh we wish to develop it further and um yeah keep it going thank [Music] you all right we have next winner which is this challenge [Music] accepted I will play the video I'm going to learn rust this [Music] year I will be eating hey starting tomorrow I will do 1,000s I want to run the marathon yeah yeah I get it we've all been there you want to do something great but ended up not doing anything at all but fear not after 2 days of tireless work we have found a solution introducing challenge accepted peer pressure on demand powered by blockchain technology social pressure and Fu fear of messing up with challenge accepted you can use your wallet to connect with your social graph to challenge and get challenged by your beloved friends create a challenge set a stake select a jury jury are like human validator nodes they manage the safe and verify whenever you succeeded or not and finally beneficiary a charity of your choice will get the money if you fail your challenge the challenge will be visible to all your friends don't mess it up now let's get to work we only have 3 weeks to get back to shape let's go [Music] [Applause] boy 3 weeks later the deadline has arrived jury now makes a verdict they are the owners of nosis safe and they will decide on the [Music] outcome if you fail you will lose all the money and respect of your friends if you succeed everyone will know how tough you are it all depends on you so let me ask you do you accept the [Music] [Applause] challenge [Applause] [Music] um GM thank you thank you for the Applause I really enjoyed it uh so the main idea of the project was to you know convert the smart contract into the social contract and I always like challenging my friends and my family to do some stuff but over time as I transition more to the to you know from the mid space to the um to the cyber space I started to have more friends um and on the internet and I like the possibility to challenge people you know from the Social Circles so yeah um we just came up with this idea that you know like it would be nice to you know use the open protocol to challenge other people and use you know like this uh um um be motivated by um other people so yeah thanks congrat guys I believe we have one more Wier and this are circuit berer [Music] UI guys guys are you with us would you like to join us oh nice so big big Applause one more [Music] [Applause] [Music] time to play video yeah maybe we actually um um we put our uh submission up I think it will take longer yeah set up okay maybe uh we just do the video and like explain a little bit to it you have the microphone so tell me when you're ready so hello guys and yeah this was very surprising now that we won we didn't expect that and yeah maybe we can start playing the video and hey guys I'm Philip hey guys I'm valo and we're circuit breaker UI um currently or in the past couple months circuit breakers have been pretty much in the hype in the security ecosystem of ethereum uh but it's a highly technical product and there is no real way to to manage them especially in terms of having a good UI uh good visual interface and for non-technical people there is basically no way to to interact with circuit breakers and that's what why what why um we have been building here at uh East Bara um we have basically built a and a visual security dashboard uh for circuit breakers um yeah so here we uh basically are tracking tvl over time we're trying to make it very easy for non-technical people people that are not taxy uh to understand socer Breakers and indirect with them um so we have built a visual dashboard for for example if you're trying to track TV all uh we have tracked over time we also have computed a protocol Health score we have um a firewall activity page where uh different Circle break events that have been uh emitted on the blockchain itself are getting listed uh and yeah that's that's pretty much it we're basically thriving to make circuit breakers more easy more understandable for non-technical people non-ac people and for us the goal is really to make circuit breakers inclusive in a way that people that do not necessarily have solidity skills can manage circuit breakers um and basically configure them without having to know these for that we also have like multiple Pages like the dashboard General page like the alerting page fire wall activity page which you can also say here on a like short view here and like you can also go into the details but also you can view and on the settings page even manage your uh dashboard where you can in depth like set up how you want to view the thresholds and in general circumstances and parameters of your circuit breaker inside your liquidity sensitive protocol yeah exactly so again the goal is very much to make a highly technical product uh available and inclusive for non-technical people make it easy to understand because that's we think the main problem in web fre as a whole is that the space is too technical yeah so just one thing to say there is Philip also going to give now explanation on circuit breakers um quick tldr and circuit breakers if you're not aware uh circuit breakers are basically a tool U to prevent hacks in real time and it's a highly technical Tool uh they have gained some Traction in the ethereum Eos uh in the ethereum security ecosystem because there has been an EAP published but the problem there is that it's a very technical tool and in order for it to realistically work you need a way to manage it especially for non-technical people and that's basically what the what our hack was for provide an easy way to to manage that tool and protect the protocol against getting hacked so for context just like a very short outline on what circuit breakers are you can in your smart contract track a parameter which in most cases will be the liquidity outflow you can drag it over time and if a certain threshold is passed you would then be able to reject a transaction or take any other form of measures to prevent the hack and the most important thing about that is there's a lot of tooling for security out there but most of it is not being able to or like actually all of it is not being able to prevent the hack single transaction hacks because the hack prevention has to happen inside the logic of the smart contract to be able while the transaction executes the hack transaction executes not being able to ex so I know it's a little bit complicated to explain but like this dashboard will help a lot we believe will help a lot to onboard new people into yeah the C it's basically about improving ux in web free because that's one of the big hurdles that web free as a whole has a bad ux and that's what what we wanted to fix there good UI good ux for a very technical product thanks a lot [Music] all right guys I believe we have one more last winner good job TCP [Applause] [Music] [Applause] to can we invite you here big Applause guys W hey we are TCP actually it's just a short hand but the full name in po means what's up P but in the English it actually is just dispenser you can think about this like that we built like Hardware powered project on top of olive zero and mantle and we want to show you how it works so stay tuned so let me show you how it works obvious says voice over right so now you see that incoming is coming a QR code we prepare two of them because we support Al zero and mantle so sub wallet for zero metam for manle so it opens the wallet with browser because we need the browser we need the wallet context right and when you click order drink we are doing photo of you right because we also prepared like order book where we store photos and the addresses so you can see like who the who was the last one order drink and you have all the Leist orders of drink so when you do this uh we're listening on events from our smart contracts and in those happenings we are starting pouring you a drinks uh obviously we need your cup right so we using proximity sensor so if the cup is not presented uh we want to put a drink when you have a drink you're happy to enjoy you you can sit drink sleep and enjoy your [Music] [Applause] day so forties uh we actually went for Al zero and MTO as our chains we support for okay gmgm thank you we stop the video because the second part is actually explaining software Hardware ET so I would say the boring part uh thank you for the heon it was a really great time I would say we build the the best project so far on all of the Hons the most fun and I totally encourage you to join us at the booth uh we can pour you some water uh you can try the project real life because it's working uh so uh about the problems and challenges so far uh close shops electronic shops and parts that was difficult and today when we came actually to like open and make it work our uh fluid pump was not working so we managed to fix so that's great uh thank you again and really happy to enjoy the [Music] haon hey guys that was the these are were like amazing projects and I hope you enjoyed being here we really are glad that you came to so and built amazing projects with us so congratulations one more time and thank you very [Music] much yeah guys so as we wrapping up um one short announcement we'll be cleaning up the whole venue we appreciate any volunteers to help up uh not obligatory but you know it's a community event so why not and uh we have at 600 p.m. in club spot we are starting the closing party uh drinks are on us the finger food is on us Matt will be dejing [Applause] there uh yeah and Adam too do we have Adam here he's not here but he'll make an awesome party too uh yeah guys thank you so much for the last what was it four days five days it was [Music] [Applause] [Music] [Applause] amazing yeah thank you to you and to all the team I'll see you [Music] soon
