Ethereum Jobs

I’m building a new fintech platform and need an experienced Solidity developer to create the ERC20 token that underpins the entire product. Your job is to take the token from concept to mainnet-ready code, ensuring it is fully compliant with the ERC20 specification and written in modern Solidity (0.8.x). You will handle every stage of smart-contract development: architecture, coding, automated testing with Hardhat or Foundry, and deployment scripting for both a public testnet and Ethereum mainnet. Robust security practices are essential—please follow the latest OpenZeppelin patterns and include a concise internal audit so I can verify that common vulnerabilities (re-entrancy, overflow, allowance issues) are addressed. Gas efficiency, upgradeability considerations, and clear ...
