Solidity Smart Contract Development & Deployment (EVM Chains)

I'll write, test, and deploy Solidity smart contracts on any EVM-compatible chain (Ethereum, Polygon, Autonomys, Base, etc.). Using Foundry for development and testing. Includes: contract code, unit tests, deployment scripts, and Blockscout/Etherscan verification. Experienced with DeFi patterns, token contracts, on-chain registries, and upgradeable proxies.
