How to choose a dApp developer

1. Real on-chain track record, Ask what they’ve shipped that holds real value or volume.
2. Security & audits, Confirm they design for audit and coordinate a third-party review before mainnet, ideally against Solidity’s official documentation and a firm like ConsenSys Diligence. See our smart contract audit cost guide for what that review typically runs.
3. Full-stack, not just contracts, A dApp is contracts plus a real app, make sure they do both.
4. Fixed price + ownership, Avoid open-ended hourly; own the contracts and code.
