Smart Contracts 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 ...

I’m ready to dive deep into everything required to generate flash-USDT and need a patient expert who can walk me through the process end-to-end. I already understand the basics of blockchain but have never attempted a flash loan or similar USDT operation, so I want guidance that starts with core principles and ends with a hands-on proof-of-concept I can replicate on my own. Here’s what I’d like from you: • A concise overview of how flash loans work specifically with USDT, including network choices (Ethereum, Tron, BSC, etc.) and the pros / cons of each. • Step-by-step instructions to set up the required environment—wallets, Web3 provider, Solidity or Vyper tooling, and an IDE such as Remix, Hardhat, or Truffle. • Annotated sample contracts or s...
