Tips from the field

  • 1.

    Use wagmi + viem as your foundation. They're the most modern and well-maintained options.

  • 2.

    Always handle loading, error, and disconnected states explicitly. Web3 has many failure modes.

  • 3.

    Test with real wallets on testnets, not just mocks. MetaMask behaves differently than test mocks.

  • 4.

    Cache RPC calls aggressively. Users on slow connections and RPC rate limits will thank you.

  • 5.

    Build mobile-first. Many users access dApps through mobile wallet browsers.
