Smart Wallet Launch-Ready Checklist

Test your app with Smart Wallet enabled on using the Beta SDK. See our guide.

If your app is using Sign in with Ethereum or similar, ensure you are ERC-6492 compliant. Viem's verifyMessage makes this very simple.

If your smart contracts do any signature validation, ensure they follow ERC-1271 when the account is not an EOA.

Your production app, or its wallet provider, should be using Coinbase Wallet SDK version 4.0 or later. See Release Plan for more details.

Magic Spend enables users to get "just in time" transaction funding from their Coinbase account. This is currently supported for ETH only on Base. To give users the best experience, apps should make use of the auxiliaryFunds capability, documented [here](#TODO /features/magic-spend) and ensure they are not blocking actions based solely on onchain balance checks.
