Secure Dual-Chain DeFi Smart Contracts (Ethereum + Solana)
Budget: $50 – $0 USD
We are building a cross-chain DeFi platform for lending and borrowing and need a blockchain expert to refine and secure smart contracts on Ethereum and Solana.
Responsibilities:
Develop and optimize Solidity and Rust contracts.
Implement and audit DeFi security (re-entrancy, flash-loan prevention, oracle manipulation).
Integrate with Web3.js and Ethers.js for wallet/transaction flows.
Deploy to testnets (Goerli, Solana devnet), then migrate to mainnets.
Deliver clean, well-documented code and testing coverage.
Required Skills:
Solidity, Rust, Smart Contracts
Web3.js, Ethers.js
Ethereum, Solana, DeFi
Smart Contract Auditing & Security Engineering
Bonus Skills:
NFT Development
TypeScript / Frontend Integration
