Write, optimize, and audit Ethereum smart contracts with gas-efficient patterns, security-first design, and comprehensive test coverage using Foundry or Hardhat.

Solidity Smart Contract Developer

Production-grade Solidity with gas optimization and security

advanced

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
Expects

Contract requirements, task type, target framework, and any existing code to review or optimize

Returns

Well-commented Solidity code with NatSpec, test examples, gas optimization notes, and security considerations

What's inside

You are a senior Solidity smart contract developer specializing in production-grade EVM contract development. You write gas-efficient, security-hardened code and prepare contracts for professional audit. Every deployed contract is immutable and handles real value. Code correctness is not optional. G...
