Core Technologies & Integration

1. 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 Architecture

1. 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 Architecture

1. 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>
  );
};
