Core interfaces and clients for interfacing with the Alchemy Signer API. ## Enumerations | Enumeration | Description | | :-------------------------------------------------------------------------------------------- | :---------- | | [AlchemyMfaStatus](/wallets/reference/account-kit/signer/enumerations/AlchemyMfaStatus) | - | | [AlchemySignerStatus](/wallets/reference/account-kit/signer/enumerations/AlchemySignerStatus) | - | ## Classes | Class | Description | | :--------------------------------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [AlchemyServerSigner](/wallets/reference/account-kit/signer/classes/AlchemyServerSigner) | AlchemyServerSigner is a signer that can sign messages and typed data using an access key. It extends the SmartAccountSigner interface and uses the ServerSignerClient to sign requests. Primarily intended to be used server-side. | | [AlchemySignerWebClient](/wallets/reference/account-kit/signer/classes/AlchemySignerWebClient) | A lower level client used by the AlchemySigner used to communicate with Alchemy's signer service. | | [AlchemyWebSigner](/wallets/reference/account-kit/signer/classes/AlchemyWebSigner) | A SmartAccountSigner that can be used with any SmartContractAccount | | [BaseAlchemySigner](/wallets/reference/account-kit/signer/classes/BaseAlchemySigner) | Base abstract class for Alchemy Signer, providing authentication and session management for smart accounts. Implements the `SmartAccountAuthenticator` interface and handles various signer events. | | [BaseSignerClient](/wallets/reference/account-kit/signer/classes/BaseSignerClient) | Base class for all Alchemy Signer clients | | [MfaRequiredError](/wallets/reference/account-kit/signer/classes/MfaRequiredError) | - | | [NotAuthenticatedError](/wallets/reference/account-kit/signer/classes/NotAuthenticatedError) | - | | [OauthCancelledError](/wallets/reference/account-kit/signer/classes/OauthCancelledError) | This error is thrown when the OAuth flow is cancelled because the auth popup window was closed. | | [OauthFailedError](/wallets/reference/account-kit/signer/classes/OauthFailedError) | This error is thrown when an error occurs during the OAuth login flow. | | [OAuthProvidersError](/wallets/reference/account-kit/signer/classes/OAuthProvidersError) | - | | [ServerSignerClient](/wallets/reference/account-kit/signer/classes/ServerSignerClient) | ServerSignerClient is a client for signing messages using an access key. It extends the BaseSignerClient and uses the ApiKeyStamper for signing. Primarily intended to be used server-side. | | [SolanaSigner](/wallets/reference/account-kit/signer/classes/SolanaSigner) | The SolanaSigner class is used to sign transactions and messages for the Solana blockchain. It provides methods to add signatures to transactions and sign messages. | ## Interfaces | Interface | Description | | :---------------------------------------------------------------------- | :---------- | | [ErrorInfo](/wallets/reference/account-kit/signer/interfaces/ErrorInfo) | -
