Problem Statement

Problem: Despite all the publicity of on-chain data, the marketing and product management in web3-projects are surprisingly uninformed and are built on intuition and common practices. Because of that, creators waste their time and budget on growth efforts that do not return the expected results. Particularly painful it is for token-based projects in the growth stage, when the token is not yet on the market, and creators can just guess who will be the future holders.Our solution: We build a user analytics platform to empower web3 project creators. Particularly, we concentrate on pre-mint stage and allow creators analyze their NFT mint list users as well as their on-chain activity. We use ML to surface insights on who are their community's most influential members, connect their web3 and web2 identities, find new opportunities for collaborations, create lookalike audiences for targeting, filter bots, and more, to give creators full control over their token-project launch or NFT mint.What is implemented in the submission:The landing page (slise.xyz) and the app (app.slise.xyz) with demo collections and mint list upload functionality, working on Ethereum."Dashboard" page with a short preview of wallets and mutual holders tables and information on Whales and BC holders (bots and social are not working yet).Sell-out prediction module where given "Mint price" and "Supply" the probability of sell-out is predicted for a given mint list."Mint list" page with a table view of individual wallets in the mint list and their features."Mutual holders" page with a list of collections with the largest interest of mutual holders as well as their stats."ML targeting" page with data cloud visualization and "export to a file" functionality of a list of new wallets similar to the mint list wallets by a given threshold.bots detecting, multi-wallets, and "social activity" pages are presented for demonstration of future functionality only and hasn't been implemented yet (2 weeks, c'mon). [[ There is a known bug with an empty name showing for new collections, just click on the empty row in the dropdown, the data will be displayed ]]We really pushed our limits to make it possible and thank the organizers for this opportunity."Mint out or die trying" (c) Slise

Solution

The Slise project was developed and uses a variety of APIs and algorithms to build analytics on collections and wallets. We used Node.js + TypeScript as the main backend language and also: PostgreSQL as the main database with Prisma ORM, Redis for caching, and Amazon S3 for file storage. Deploying to Heroku as a container. Github for version control.The frontend of the app was made using JavaScript, Next.js, MUI, HTML & CSS, and deployed to Vercel. We used Charts.js for dashboards, axios for communication with backend, and localstorage as frontend storage.We build REST API for communication with Frontend according to the Open API specification.To work with the blockchain, we used native web3.js, Bitquery, Moralis, NFT Port, Covalent. web3.js: getting the current Ethereum exchange rate Covalent: getting collection holders NFT Port: fetching collection info (rate, logo, supply, transaction stats) https://api.nftport.xyz/v0/transactions/, fetching NFTs https://api.nftport.xyz/v0/nfts/ Bitquery: fetching user token balances by address Moralis: getting user balances Moralis.Web3API.account.getNativeBalanceSince we have to process a large amount of data, we have divided the whitelist parsing into 2 asynchronous stages:After the user uploads the whitelist, we save it and create a parsing task for the queueIn the background process, we receive a task with wallet data from a file and asynchronously process each user: csv parsing in loop → get balance for user & get tokens for user → storing in our databaseOur ML service was written and python and deployed through FastAPI. As of submission date we only chose to tackle 2 big tasks (sell-out prediction and targeting) while bot detection and multi-wallet require much longer R&DThe first task was approached through linear regression trained on public data of NFT collections and implemented in scipy and sklearnFor the targeting wallets were encoded using OH encoding based on their NFT holdings and compared using cdist.
