Uh, it's it's glad to see you all in Taipei. So, I'm really excited to introduce you to Not. And I think most of you guys never heard of Not before. So I'm going to go I'm going to give you a quick brief of our product. So what is noted?
Ned is a fullstack web3 developer platform. Um so uh we provide high performance web3 data APIs real time web hooks um uh data stream and enterprise grade nodes infrastructure for um simlessness blocks and access. We support 12 uh 12 chains uh from major event chains like Ethereum base, optimism, arbitrum and and also we support um non-event chains as well and we are expanding support uh to more ecosystem as well. So I'm going to show you four key features of noted that you can use at the at this hackathon. So let's get started with elastic node.
This is kind of a fully managed blockchain node infrastructure. So it means we are like node provider service. So you can access to blockchain nodes with our RPS endpoints. So no setup and no maintenance is required. And you know when you when you interact with a nodes um blockchain nodes the the performance is really important right.
So our product ensures low latency, high high throughput processing uh with an optimized load balancing. So you can get the um quick responses of from our nodes as well. And we support multiple event chains like Ethereum base and other other event chains. So let me give you quick um demo. So when you first sign up for nic console you can see uh the first project is created already and under the networks tab you can see the all the list of chains that we are supporting and these are connected automatically when you create a project.
Under the dashboard tab you can find the API key. So with this API key you can access to uh any chains we are supporting and you can test you can do quick tests in our developer documents. So maybe this is the one of the most you're going to use um for for the JSON RP methods. So, let's copy and paste your API key into the header like this. And you can change the network you want to use, but I'm going to keep it with uh either remain for this demo.
And you can you can change the parameter values, but I'm going to keep the default value so that I can get the logs data of latest block. So, so you can get this kind of data using our RPC endpoints and also you can get the matrix data from our console. So you can select the targeting network and you can get this kind of data and also you can monitor the request logs on the left menu. So you can get the all the API calls logs that you made um in the past. So next up is web3 data API.
So sometimes you need um um more complex data data like structured data not not only for not only the row data. So if you want to get useful data from uh the blockchain node, you have to process uh and convert into convert it into uh the useful data. But uh web3 data API simplifies this process for uh giving you the ready to ready to use data. So we index, we pre-indexed and pre-process the onchain data and it supports the multiple event chains as well. Uh with this API you can get the token balances or token transfer events or you can get the transaction histories for uh analytics.
So let me show you how it works. So in in our developer documents you can find the the list of web three data APIs as well but each chains uh supports different APIs. So before using it, please make sure to uh this API uh covered your uh targeting chains. So I'm going to use this get tokens. I want to buy accounts API for demo to get the data uh to get the token balance data by uh owned by a specific account and I set it as I set the account with count value as true so that you can get the total number of token balances as well.
And also you can monitor this uh API calls through our uh console as well so that you can reduce the debugging time because you don't have enough time to build in this uh short-term uh hackathon. This will be the good features for using it. And as you can see, this account owns over 6,000 tokens. But with if you're using node APIs to get this data, you have to um make a 6,361 API calls to get this kind of data. But with our S3 data API, you can get this data in a single API call and we also support a pushbased notification feature which is called a web hook.
Um so instead of polling you can get uh notified uh in real time and we are supporting a predefined web hook event type. So you can get the uh day uh the useful data you want to use by these kind of event types. So with this feature you can monitor new uh transactions and token transfers and other events as well. So let me show you how to use it in our console. You can find the web hook menu on the left side here.
Let's create one and you can select the network that you want to use and also there are bunch of uh predefined event types here and also you have to input your web hook server URL to get get response from your our web hook. So I'm going to use web hooks site for testing. Now um I'm going to copy the URL of this web server and paste into here and set the required condition parameters here. And let's create button. There we go.
We just made we just create a a web hook for block period. It means you can get the block data every time the new block has been generated. So you you can get the block data with this event type. And there's another option to get the real time data. This is a data stream.
So you can subscribe the to the live blockchain events like blocks transactions or um your custom contract events. But the different thing is you have to u maintain the person connection for for uh receiving this kind of continuous updates. And we also support uh the the predefined event types for this feature as well. So you can monitor these kind of things as well. So there is a quick guide to use our stream feature as well.
Please scroll all the way down to the stream. You can find the stream quick start guide here and you can follow this step by step. Then you can uh configure your environment setup. Also there is a example code to run this one. I'm going to copy this one and paste into our my uh file and let's change the required field as that I want to use and also you have to paste your API key into this parameter as well and select the protocol network then save it.
Okay, let's run this script. Then it will give you the subscription ID ID and then we uh subscribe the block period as I did in for the web hook as well. So you can get the blockchain data like this. So both are the good options to get real time data. So you can try out yourself as I did.
So please scan our console to sign up and try it out. And also there is a uh um bunch of the tutorials and the guides for using our product. In the meantime, do you have any questions for our key features that I showed? No. Okay.
So key difference between web hook and stream. So uh for if you're using uh the web hook you have to build your web hook servers to get uh the response from our web hook and the if you're using the data stream you have to uh maintainance maintain the the connections uh to get the real uh the data updates. the test that's the main difference. Okay. And let's talk about the money the price.
So we have two tracks. So one is the DFS on base and the other one is M chain DFS. So let's break down break them down for the base track. So here's what you need. Of course, you have to build on the base chain.
It doesn't matter uh you're going to use mainet or test net, but I recommend you to use uh a test net because we we're not going to give you the real e um real tokens for mainet. So you can get the faucet uh for the the test net and you have to use at least two noted tools and we will judge it based on um practical usefulness, creativity and innovations. And we want to see how well you're going to integrate our features into your uh project. And your D app must for for the multi chain track your G must support at least two event compatible chains we are supporting Ethereum base optum optimism polygon and kaya for event chains please use them and for this track you use at least one Ned tool and we'll be looking for how effective your motion integration is and how uh innovative your um data utilization is and originally and depth of node integration as well. So, I'll be um I'll be in our booth for this hackathon period.
So, if you want to have if you have any questions, please come over to um come over to us or if you cannot find us, please uh contact us with these three channelers. So, and if you have any questions after this hackathon, you can leave your questions through our developer documents. There is a Q&A sections. So, prefer to use them. And let me show you how to uh add our noty port on Discord.
When you scan this QR code, maybe you can get sorry when you scan your when you scan QR code, you can get this kind of page. So, please add your Please add our notepod and a author author sorry author authorize this one. Sorry, it's hard to pronounce for me. And you can DM to our not like this. So if you if you want to get the quick help then please use this not okay and let's get back to so that's it from me.
So if you have any questions please come over to our booth and I wish you luck. um you're going to win any uh any tracks or main tracks and happy hacking. Thank you.
