BNB Smart Contract dApp Development

I’m building a decentralized application and need a Solidity specialist who can design, code, test, and deploy production-ready smart contracts on BNB Smart Chain. The focus is entirely on smart contracts—no token launch, no supply-chain features—so every line of code must optimise for dApp functionality, security, and low gas fees.

You’ll start by discussing the core logic with me, translate those requirements into clear Solidity interfaces, then implement them using Hardhat (or Truffle) and Ethers.js/Web3.js for scripting. Once the contracts compile cleanly, we move to automated unit tests, integration tests on the BSC testnet, and a lightweight audit covering re-entrancy, overflow/underflow, and access-control checks. When everything passes, you’ll deploy to mainnet and provide a concise hand-off guide.

Deliverables:
• Well-commented Solidity source code
• Hardhat/Truffle project with tests
• Verified contract address on BSCScan
• Deployment & upgrade instructions
• Brief security audit report

Acceptance criteria: all tests green on testnet, contract verified on BSCScan, and no Critical/High issues in the audit.

If you’re comfortable with Solidity 0.8.x, Hardhat, and the peculiarities of BNB Smart Chain, let’s make this dApp live.
