DeFi Lending Protocol

DeFi startup needed a multi-chain lending protocol that could operate on both Ethereum/EVM chains and Solana, with seamless user experience and gas-efficient smart contracts.

Developed smart contracts in Solidity for EVM chains (Ethereum, Polygon, Arbitrum) and Rust/Anchor for Solana. Built a unified frontend using React and Web3.js that supports both ecosystems. Implemented cross-chain bridge integration and gas optimization techniques.

Successfully deployed on 4 chains, $50M+ TVL within 3 months, 40% gas savings through optimization, zero security incidents, and 10K+ active users across all chains.
