Web3 DeFi Protocol Developer -- 2
Budget: $3,000 – $5,000 USD
I’m preparing to push a new DeFi protocol from proof-of-concept to main-net and I need a seasoned Web3 developer to make that possible. The core idea and tokenomics are already defined; what’s missing is the hands-on expertise to turn them into production-ready smart contracts, wire them to a responsive front end, and make sure everything is secure before launch.
You’ll be working in Solidity and the usual Web3 toolchain—Hardhat or Foundry for tests and deployments, ethers.js or web3.js for the dApp connection, plus React/Next for the UI layer. I’m open to launching on Ethereum, BSC, or Polygon; if you have a strong case for one of them, I’d love to hear it.
Key things I need from you:
• Clean, gas-efficient smart contracts with full unit tests
• Seamless front-end integration that signs and broadcasts transactions smoothly
• Deployment scripts and clear documentation so the project stays maintainable
• A round of internal security checks (static analysis, fuzzing, edge-case testing) before any external audit
If you can also help refine the technical spec as we go, that’s a plus. Share links to at least one live DeFi project you’ve built or audited, your GitHub, and a quick note on your availability. Let’s get this protocol live.
