You’ve written your smart contracts and frontend — now it’s time to test like a pro before launch.

Here are a few tips to make your debugging smoother on the Metis testnets:

:wrench: Smart Contract Testing

  • Use Hardhat with Chai or Foundry for unit testing your contracts.
  • Mock external calls and oracles using tools like hardhat-network-helpers.

:test_tube: Frontend Testing

  • Use wagmi + Ethers.js to test contract interactions locally before pushing live.
  • Always connect your dApp to Metis Sepolia or other testnets with proper RPCs.
  • Check your console and inspect network requests — often it’s just a minor call issue!

:toolbox: Debugging Tools

  • Use Blockscout (Metis Testnet Explorer) to:
    • Verify contract deployments
    • Track failed transactions
    • View events/logs
  • Add extra console.log() or emit statements in smart contracts for better traceability during dev.

:white_check_mark: Pro Tip: Set up a clean script for resetting your test environment so you can iterate quickly.
