Solidity Dev for Lending Protocol
Budget: $10,000 – $20,000 USD
Our team is midway through building a new on-chain lending/borrowing platform and I need a Solidity engineer who can take full ownership of the remaining smart-contract work. The core lending logic, interest-rate model, collateral accounting, liquidation flow and incentive token mechanics must be written, optimised and fully tested so we can move straight to external audit.
You will be working in a Hardhat environment (happy to switch to Foundry if that is your preference) and leveraging OpenZeppelin libraries where sensible. Gas efficiency, upgrade-safety and clean, well-documented code are paramount; I intend to keep the contracts lean enough for a formal verification pass later.
Deliverables
• Complete Solidity contracts for lending, borrowing, collateral and liquidation
• Comprehensive unit and integration tests with ≥95 % coverage
• Deployment scripts and minimal README so another dev can spin up the stack in minutes
If you have shipped production DeFi code before—especially lending protocols—let’s talk details and timelines.
