Solidity Developer for DApp Build

Our decentralized application is almost ready for prime time; the only component still outstanding is the Solidity layer. I need production-grade smart contracts written, thoroughly tested, and deployed to an EVM-compatible chain (we can confirm the exact network together—Ethereum, BSC, Polygon, or another). Security and gas efficiency are top priorities, so well-structured code, comprehensive unit tests, and a clear audit trail are essential.

Deliverables
• Technical outline of the contract architecture
• Fully commented Solidity contracts compiled with the latest stable compiler
• Hardhat/Foundry test suite covering core logic and edge cases
• Deployment scripts plus a brief run-book so the contracts can be verified on-chain
• Post-deployment support for any critical fixes discovered in the first release window

Please highlight previous projects where you owned contract design end-to-end, and note any experience with security tooling such as Slither, MythX, or Echidna. If you enjoy clean, efficient code and can turn requirements into bullet-proof smart contracts, let’s talk.
