Manage self-custody wallets to allow for management of self-custody domains. ## Verifying Self-Custody Wallets Before you can initiate self-custody operations, you must first [verify the self-custody wallet](/openapi/partner/v3/#operation/getExternalWalletVerification) (only needs to be done once per wallet). This involves: 1. [Fetching a verification message to sign](/openapi/partner/v3/#operation/getExternalWalletVerification) 2. Collecting a `personal_sign` signature from the wallet owner 3. [Submitting the signature](/openapi/partner/v3/#operation/postExternalWalletVerification) to register the verified wallet After verifying a wallet, it will be returned by the Single-Wallet and Wallet List routes, with the type of `EXTERNAL`. ## Supported Self-Custody Wallets - Externally Owned Accounts (EOAs) - [ERC1271](https://eips.ethereum.org/EIPS/eip-1271) Smart Contract wallets deployed on Polygon
