Build Smart Contracts for CritiQ -- 2

Our new platform, CritiQ, needs a suite of robust, reusable smart contracts. I already have the product vision, tokenomics draft, and high-level user flows; now I’m ready to turn that vision into audited code.

Here’s what I expect from this engagement:

• Architecture & specification – refine requirements with me and translate them into a concise technical spec.
• Development – implement the contracts in Solidity using best-practice libraries such as OpenZeppelin, with comprehensive unit tests in Hardhat or Truffle.
• Security & gas optimisation – apply industry-standard patterns, write clear modifiers, and run automated analysis (Slither, MythX, or similar) before handing the code over for an external audit.
• Deployment & hand-off – provide scripts for testnets and mainnet, full documentation, and a walkthrough so my in-house engineers can integrate the contracts with our front-end.

Although I haven’t finalised the exact chain, I’m open to Ethereum mainnet, Polygon, or BSC; advise me on cost, community reach, and tooling so we deploy where CritiQ gains the most traction.

Acceptance criteria:
1. Contracts compile without warnings, achieve >95 % unit-test coverage, and pass static-analysis scans with zero critical issues.
2. Documentation explains each public interface, constructor parameter, and role.
3. Deployment scripts succeed on one public testnet and mainnet.

If you have a track record of shipping secure, efficient Solidity code, I’m keen to collaborate and push CritiQ live.
