Problem Statement

MicroVest: Democratizing Web3 Investments with Verified PoolsWhat is MicroVest?MicroVest is a decentralized investment platform that bridges the gap between traditional investors and Web3 opportunities. By combining Web3Auth's seamless onboarding, Chronicle's reliable price feeds, and Sign Protocol's verifiable attestations, we've created a platform that makes Web3 investing accessible, secure, and transparent.Core Features1. Seamless OnboardingLogin with Google to get an instant Web3 walletNo seed phrases or complex wallet setups requiredGasless transactions for better user experienceInstant access to investment opportunities2. Verified Investment PoolsCreate or join investment pools with full transparencyEach pool is verified through Sign Protocol attestationsReal-time price feeds from Chronicle oraclesSmart contract-based security and automationLow minimum investments (starting at 0.1 ETH)3.

Solution

Core Technologies & Integration1. Authentication & Wallet Management// Web3Auth Integration for Seamless Onboarding - Implemented Single Factor Auth using Web3Auth - Firebase for authentication backend - Custom implementation with ethers.js for Web3 interactions // Key Integration const web3auth = new Web3Auth({ clientId: process.env.WEB3AUTH_CLIENT_ID, web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_MAINNET, privateKeyProvider: new EthereumPrivateKeyProvider({ config: { chainConfig } }) }); // Google Authentication Flow const signInWithGoogle = async () => { const auth = getAuth(firebaseApp); const provider = new GoogleAuthProvider(); const result = await signInWithPopup(auth, provider); const idToken = await result.user.getIdToken(); return web3authProvider.connect({ verifier: "microvest-auth", verifierId: result.user.uid, idToken }); };2. Price Oracle Integration// Chronicle Protocol Integration for Real-time Price Feeds contract MicroVestPool { IChronicle public immutable oracle; function getAssetPrice(string memory symbol) public view returns (uint256) { (uint256 price, uint256 timestamp) = oracle.readWithAge(); require(block.timestamp - timestamp <= MAX_PRICE_AGE, "Stale price"); return price; } }3. Attestation System// Sign Protocol Integration for Pool Verification contract PoolAttestation { ISP public signProtocol; function createPoolAttestation( address creator, uint256 poolId, string memory symbol, uint256 targetAmount ) external returns (uint64) { bytes[] memory recipients = new bytes[](1); recipients[0] = abi.encode(creator); bytes memory data = abi.encode( poolId, symbol, targetAmount, block.timestamp ); Attestation memory attestation = Attestation({ schemaId: poolSchemaId, attestTimestamp: uint64(block.timestamp), data: data, // ... other attestation fields }); return signProtocol.attest(attestation, "", "", ""); } }Smart Contract Architecture1. Core Contracts// Pool Factory Pattern for Scalability contract MicroVestFactory { mapping(uint256 => address) public pools; uint256 public poolCounter; event PoolCreated(uint256 indexed poolId, address pool); function createPool( string memory symbol, uint256 targetAmount, uint256 minInvestment ) external returns (uint256 poolId) { poolId = ++poolCounter; address pool = address(new MicroVestPool( msg.sender, symbol, targetAmount, minInvestment )); pools[poolId] = pool; emit PoolCreated(poolId, pool); } }2. Investment Logic// Innovative Investment Distribution contract MicroVestPool { struct Investment { uint256 amount; uint256 shares; uint256 entryPrice; uint64 attestationId; } mapping(address => Investment) public investments; function invest() external payable { require(msg.value >= minInvestment, "Below min"); uint256 price = getAssetPrice(symbol); uint256 shares = calculateShares(msg.value, price); investments[msg.sender] = Investment({ amount: msg.value, shares: shares, entryPrice: price, attestationId: createInvestmentAttestation( msg.sender, msg.value ) }); } }Frontend Architecture1. Responsive Layout with Tailwind// Custom Hook for Web3 Integration const useWeb3 = () => { const [provider, setProvider] = useState<any>(null); const [address, setAddress] = useState<string>(''); const connect = async () => { const web3authProvider = await login(); const ethersProvider = new ethers.BrowserProvider(web3authProvider); const signer = await ethersProvider.getSigner(); const userAddress = await signer.getAddress(); setProvider(ethersProvider); setAddress(userAddress); }; return { provider, address, connect }; }; // Pool Component with Real-time Updates const PoolCard = ({ pool }) => { const { provider } = useWeb3(); const [currentPrice, setCurrentPrice] = useState<number>(0); useEffect(() => { const fetchPrice = async () => { const price = await getAssetPrice(pool.symbol); setCurrentPrice(price); }; const interval = setInterval(fetchPrice, 30000); return () => clearInterval(interval); }, [pool.symbol]); return ( <div className="bg-white rounded-xl shadow-sm p-6"> {/* Pool UI */} </div> ); };Notable Technical Challenges & Solutions1. Price Feed OptimizationImplemented caching layer for Chronicle price feedsUsed WebSocket connections for real-time updatesAdded fallback mechanisms for price feed failures2.
