DeFi Protocol Developer Needed
Budget: €3,000 – €5,000 EUR
My team is building a new DeFi protocol from the ground up and I need an experienced blockchain developer to architect, code, and thoroughly test the core smart-contract suite. The chain, feature set, and tokenomics are still flexible; I’m open to your recommendation after we discuss security, cost, and community factors for networks such as Ethereum, BNB Smart Chain, or Polygon.
Scope of work
• Design the overall protocol architecture, including the governance and utility token contracts.
• Write production-ready smart contracts (Solidity or Vyper) and deploy them with Hardhat, Foundry, or a comparable framework.
• Set up a complete test suite with unit tests, integration tests, and coverage reports.
• Connect the contracts to a lightweight front-end demo via ethers.js or web3.js so the team can interact with the protocol during internal reviews.
• Deliver clear, developer-friendly documentation that explains contract structure, upgradeability strategy, and key security assumptions.
Acceptance criteria
– All contracts compile without warnings and pass 100 % of the agreed-upon tests.
– Gas usage is optimized and benchmarked.
– Independent audits (arranged separately) return only low-severity findings or lower.
– Deployment scripts and instructions allow the team to reproduce each step on testnet and mainnet.
I’m ready to move quickly and will fund work in milestones tied to the deliverables above. If you’ve shipped DeFi products before—especially lending, liquidity pool, or yield farming protocols—let’s discuss how your expertise can shape this project.
