Architect & Build Smart Contracts
Budget: $15 – $25 USD
I’m at the very first, idea-only stage of a new Web3 product and need a full-stack developer who can take that concept and turn it into production-ready smart contracts. The immediate focus is Solidity contract design, architecture, coding, security best practices, automated testing, and deployment to at least one public testnet.
Because this is still only a concept, I’m relying on you to shape the technical approach. Your proposal should therefore read like a mini-roadmap: explain how you would gather requirements, suggest the most suitable blockchain (Ethereum, Polygon, BSC or another you recommend), outline the tools you prefer—Hardhat, Foundry, Truffle, OpenZeppelin, Slither, etc.—and map out milestones through testnet deployment and audit.
Deliverables I need to see:
• Complete Solidity source code hosted in a private Git repo
• Unit and integration tests with a clear coverage report
• Deployment scripts and reproducible steps for testnet release
• Short technical doc explaining contract architecture, upgradeability choices, and security considerations
Acceptance criteria: all tests pass, contracts compile without warnings, gas usage is optimized, and the code is ready for third-party audit.
Please send a detailed project proposal that addresses the above points, includes an estimated timeline, and highlights any comparable smart-contract work you’ve done.
