Solidity developers write, test, and deploy smart contracts on Ethereum and EVM-compatible blockchains. Their daily work includes designing contract logic for DeFi protocols or token systems, writing unit and integration tests in Hardhat or Foundry, optimizing gas usage to reduce transaction costs by 30-60%, and conducting internal security reviews. They also integrate contracts with frontend dApps using Web3.js or Ethers.js and manage deployment pipelines across testnets and mainnet.
Solidity is purpose-built for Ethereum and all EVM-compatible chains like Polygon, Arbitrum, and BNB Chain, which collectively hold over 80% of total value locked in DeFi. Rust is used for Solana, Near, and Polkadot ecosystems. Solidity benefits from the largest developer community, the most battle-tested libraries (OpenZeppelin), and the broadest tooling ecosystem including Hardhat, Foundry, and Slither. Choose Solidity when targeting EVM chains; choose Rust for Solana or when building blockchain infrastructure at the protocol level.
Our audit process covers five stages: automated static analysis with Slither and Mythril to catch common vulnerabilities, manual line-by-line code review focusing on reentrancy, access control, and integer overflow risks, fuzz testing with Echidna using 10,000+ randomized inputs, formal verification of critical invariants, and a detailed report with severity-ranked findings and remediation steps. The full process takes 1-3 weeks depending on contract complexity, and we re-audit after fixes are applied.
Mid-level Solidity developers with 2-4 years of experience in ERC token standards and Hardhat typically cost $50-85/hour. Senior Solidity architects with DeFi protocol design, security auditing, and gas optimization expertise range from $100-180/hour. We offer flexible engagement models including dedicated monthly retainers starting at $8,000/month for full-time developers, and project-based pricing for defined-scope smart contract builds. All engagements include code reviews and security testing at no extra charge.
Our developers deploy to all major EVM-compatible chains including Ethereum mainnet, Polygon (PoS and zkEVM), Arbitrum, Optimism, BNB Chain, Avalanche C-Chain, Base, and Fantom. A single Solidity codebase can target multiple chains with minimal configuration changes, typically just RPC endpoints and chain IDs. We also handle multi-chain deployment strategies with deterministic addresses using CREATE2, enabling identical contract addresses across 5-10 chains for a unified user experience.
