Solidity Protocol Development Experts

I’m building an on-chain protocol and need a seasoned Solidity engineer to take ownership of the smart-contract layer from design through deployment. The work can involve writing new contracts or refining the snippets I already have—whichever path gets us to safe, efficient, and upgrade-friendly code the fastest.

Day-to-day you’ll architect the contracts, write thorough tests in Hardhat or Foundry, profile gas, and apply security best practices so the code is ready for an external audit. I’m flexible on workflow as long as we end with a clean, well-documented GitHub repo and a smooth deployment script.

Deliverables
• Production-ready Solidity contracts
• Complete test suite with >90 % coverage
• Deployment & verification scripts
• Short technical hand-off guide

Acceptance criteria: all tests pass, Slither (or equivalent) flags no high-severity issues, and the contracts deploy without exceeding the agreed gas limits.

If you’ve shipped or audited similar protocols, I’d love to see links or public addresses alongside your timeline to deliver an initial mainnet-ready version.
