How to scope a blockchain task so it gets delivered
Blockchain work goes wrong when scope is vague. Before you message anyone, write down the chain (Ethereum, BNB Chain, Polygon, TRON, Solana…), the contract addresses involved, which wallet(s) users will connect with, and what "done" means — for example "users can connect MetaMask, see their token balance and claim rewards on testnet".
Ask for delivery on a testnet first, then mainnet. Agree on who deploys contracts and who holds the deployer keys. Never share a seed phrase or private key with a freelancer; give them a fresh testnet wallet instead.
Checking a developer before you hire
- Ask for links to deployed contracts or live dApps they built, and check them on a block explorer.
- Look at a public GitHub repository — commit history says more than a portfolio image.
- Request a short paid trial task (2–4 hours) before a larger milestone.
- Agree on code ownership: the repository should be in your organisation, not theirs.
Paying blockchain freelancers in crypto
Most Web3 developers prefer stablecoins. Agree on the token and network up front — USDT on TRC-20, BEP-20 or Polygon are common because fees are low. Split larger jobs into milestones and pay each one after you review it. Read our crypto payments guide for a step-by-step checklist.
