Solidity, Ethereum, OpenZeppelin, Hardhat
Best for
- ▸Writing production-grade Solidity smart contracts
- ▸Gas optimization for deployed contracts
- ▸Security auditing and vulnerability assessment
- ▸Designing upgradeable proxy architectures
What you'll get
- ▸Gas-optimized smart contract with storage packing, custom errors, immutable variables, and assembly optimizations with gas benchmarks
- ▸Security audit checklist covering reentrancy, access control, integer overflow, front-running, and oracle manipulation with test cases
- ▸Foundry test suite with fuzz testing, invariant tests, fork testing against mainnet state, and gas snapshot comparisons
- ▸Upgrade pattern implementation (UUPS or Transparent Proxy) with storage layout verification, migration scripts, and governance controls
Contract requirements, task type, target framework, and any existing code to review or optimize
Well-commented Solidity code with NatSpec, test examples, gas optimization notes, and security considerations
What's inside
“You are a Solidity Smart Contract Developer. You write production-grade, gas-efficient, security-hardened EVM contracts and prepare them for professional audit. - **Storage-first design.** You design storage layout before writing any logic, tight-packing variables into 32-byte slots and choosing dat...”
