| ## Functions | Function | Description | | :------------------------------------------------------------------------------------------ | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [alchemyWalletTransport](/wallets/reference/wallet-apis/functions/alchemyWalletTransport) | - | | [createSmartWalletClient](/wallets/reference/wallet-apis/functions/createSmartWalletClient) | Creates a smart wallet client with wallet API actions. | | [formatSign](/wallets/reference/wallet-apis/functions/formatSign) | Formats a signature request for signing messages or transactions. | | [getCapabilities](/wallets/reference/wallet-apis/functions/getCapabilities) | Gets the capabilities supported by the wallet for the given account. Delegates to viem's `getCapabilities` and renames `paymasterService` to `paymaster` for consistency with the SDK's public API. | | [grantPermissions](/wallets/reference/wallet-apis/functions/grantPermissions) | Grants permissions to a smart account by creating a session. This allows another key to perform operations on behalf of the account. | | [listAccounts](/wallets/reference/wallet-apis/functions/listAccounts) | Lists all smart accounts for a given signer using the wallet API client. | | [prepareCalls](/wallets/reference/wallet-apis/functions/prepareCalls) | Prepares a set of contract calls for execution by building a user operation. Returns the built user operation and a signature request that needs to be signed before submitting to sendPreparedCalls. | | [prepareSign](/wallets/reference/wallet-apis/functions/prepareSign) | Prepares a signature request for signing messages or transactions. | | [requestAccount](/wallets/reference/wallet-apis/functions/requestAccount) | Requests a smart account address for the provided signer using the wallet API client. | | [sendCalls](/wallets/reference/wallet-apis/functions/sendCalls) | Prepares, signs, and submits calls. This function internally calls `prepareCalls`, `signPreparedCalls`, and `sendPreparedCalls`. | | [sendPreparedCalls](/wallets/reference/wallet-apis/functions/sendPreparedCalls) | Sends prepared calls by submitting a signed user operation. This method is used after signing the signature request returned from prepareCalls. | | [signMessage](/wallets/reference/wallet-apis/functions/signMessage) | Signs a message using the smart account. This method requests the account associated with the signer and uses it to sign the message. | | [signPreparedCalls](/wallets/reference/wallet-apis/functions/signPreparedCalls) | Signs prepared calls using the provided signer. | | [signSignatureRequest](/wallets/reference/wallet-apis/functions/signSignatureRequest) | Signs a signature request using the provided signer. This method handles different types of signature requests including personal_sign, eth_signTypedData_v4, and authorization. | | [signTypedData](/wallets/reference/wallet-apis/functions/signTypedData) | Signs typed data (EIP-712) using the smart account. This method requests the account associated with the signer and uses it to sign the typed data. | | [smartWalletActions](/wallets/reference/wallet-apis/functions/smartWalletActions) | Decorator that adds smart wallet actions to a wallet API client. Provides both Alchemy-specific methods and standard viem wallet actions. | | [undelegateAccount](/wallets/reference/wallet-apis/functions/undelegateAccount) | Prepares, signs, and sends an EIP-7702 undelegation to remove delegation from an EOA. Gas is sponsored by Alchemy (requires Enterprise plan). |
