VaultiFi Ethereum Lending Contracts
Budget: ₹12,500 – ₹37,500 INR
I’m building VaultiFi, a DeFi application focused on lending and borrowing, and I’m looking for an experienced Solidity developer who can architect and code the full suite of smart contracts that will power the platform on Ethereum. The core of the job is to translate the lending-and-borrowing logic I’ve mapped out into audited, upgrade-ready contracts that are gas-efficient, secure, and easy to integrate with a React front-end.
You’ll be working exclusively on Ethereum, so familiarity with EVM quirks, OpenZeppelin libraries, Hardhat/Foundry testing, and typical ERC-20 collateral flows is essential. The contracts must handle interest accrual, collateral management, liquidation triggers, and role-based access control while remaining modular enough for future features.
Deliverables:
• Production-ready Solidity contracts for VaultiFi lending and borrowing
• Comprehensive unit and integration tests (Hardhat or Foundry)
• Deployment and migration scripts
• Concise technical documentation outlining contract architecture, key functions, and upgrade paths
Acceptance Criteria: the test suite must pass 100 % coverage for critical functions, static analysis tools (Slither, MythX, or similar) should return no high-severity issues, and gas reports must remain within reasonable limits for typical DeFi interactions.
If you have prior work on Ethereum lending protocols or similar DeFi primitives, attach links or repo samples—I’ll prioritize proven experience. Let’s make VaultiFi’s contracts rock-solid from day one.
