+## Using CDP Wallets
+
+[Coinbase Developer Platform (CDP) Wallets](https://docs.cdp.coinbase.com/wallets/non-custodial-wallets/overview) support Builder Codes on user operations from smart accounts. Pass `dataSuffix` when you send a user operation so your Builder Code is appended; no contract changes required. This works across the React hooks (`useSendUserOperation`), Node (TypeScript), and Python SDKs.
+
+See [Builder Codes](https://docs.cdp.coinbase.com/wallets/using-wallets/smart-accounts#builder-codes) in the CDP Wallets documentation for setup instructions, including how to generate the suffix with `Attribution.toDataSuffix` from `ox/erc8021`.

 ## Using Privy
 
 Privy provides a `dataSuffix` plugin that automatically appends your Builder Code to all transactions—including both EOA transactions and ERC-4337 smart wallet user operations.
