Enumerations
| Enumeration | Description |
|---|---|
| CryptoErrorType | Error types for cryptographic operations. |
| IFrameApiErrorType | Error types for iframe API integration. |
| JwtErrorType | Error types for JWT handling and validation. |
| KeybanNetwork | The KeybanNetwork enumeration defines the various blockchain networks supported by the Keyban SDK. Each member of the enumeration represents a specific blockchain network identified by its unique name. |
| SdkErrorTypes | Enum representing all possible SDK error types. |
Classes
| Class | Description |
|---|---|
| CryptoError | Error thrown when a cryptographic operation fails. |
| IFrameApiError | Error thrown by the iframe API server/client layer. |
| JwtError | Error thrown when JWT validation fails or a token is malformed. |
| KeybanAccount | Abstract account bound to a specific chain implementation (EVM, Starknet, Stellar). Provides methods to sign messages and to transfer/estimate fees for native currency, ERC‑20-like tokens, and NFTs, when supported by the target network. Obtain an instance via KeybanClient.initialize. |
| KeybanBaseError | The KeybanBaseError class serves as the foundational structure for all custom errors within the Keyban SDK. It extends the native JavaScript Error class, providing additional properties to enrich error handling with more context and information. |
| KeybanClient | Main client for interacting with the Keyban API and associated services. This class provides methods to initialize accounts, retrieve balances, query NFTs, and interact with the Keyban blockchain. |
| SdkError | Class representing an SDK-specific error. |
Interfaces
| Interface | Description |
|---|---|
| ClientShareProvider | Represents a storage provider for the client share. |
| IKeybanAccount | Account service contract. |
| IKeybanApi | Aggregated API surface exposed through the iframe transport. |
| IKeybanAuth | Authentication service contract. |
| IKeybanClientShareStorage | Storage for persisting and retrieving the MPC client share on the integrator side. |
| IKeybanDpp | Digital Product Passport (DPP) operations. |
| IKeybanLoyalty | Loyalty operations for wallet passes and tier retrieval. |
| IKeybanSigner | MPC signer contract for a given curve (ECDSA/EdDSA). |
Type Aliases
| Type Alias | Description |
|---|---|
| Address | Represents an Ethereum address in hexadecimal format. |
| AuthConnection | Represents the types of authentication connections available. |
| AuthSendOtpArgs | Arguments for sending a One-Time Password (OTP). |
| AuthSignInArgs | Arguments for signing in a user. |
| AuthSignUpArgs | Arguments for signing up a user using email and password. |
| Balance | Represents a balance with optional metadata. |
| EstimateERC20TransferParams | Parameters to estimate an ERC‑20 transfer, without fees. Derived from TransferERC20Params by omitting fees. |
| EstimateNftTransferParams | Parameters to estimate an NFT transfer, without fees. Derived from TransferNftParams by omitting fees. |
| EvmFeeDetails | EIP‑1559 fee parameters for EVM transactions. Used by EVM account transfer methods to override gas pricing when needed. |
| FeeDetails | - |
| FeesEstimation | Represents a transaction fee estimation returned by estimation methods. The concrete shape of the details field depends on the underlying network: - EVM chains: EvmFeeDetails (EIP-1559 fields) - Stellar: StellarFeeDetails (fee per operation as string) |
| FeesUnit | Represents the unit of fees in a specific blockchain. |
| Hash | Represents a cryptographic hash value in hexadecimal format. |
| Hex | Represents a hexadecimal value in blockchain-related contexts. |
| KeybanApiStatus | - |
| KeybanAssetTransfer | - |
| KeybanClientConfig | Configuration options for initializing the Keyban client. |
| KeybanNft | - |
| KeybanNftBalance | - |
| KeybanOrder | - |

| LoyaltyRewardTier | Loyalty reward tier information. |
| NativeCurrency | Represents the native currency of a blockchain network. |
| Order | - |
| OrderItem | - |
| PaginationArgs | Arguments for paginating a collection. |
| Prettify | - |
| StellarFeeDetails | Stellar fee per operation represented as a string in stroops. In congestion, Horizon exposes a higher mode fee; otherwise it's the base fee (100 stroops). |
| TransferERC20Params | Parameters for transferring ERC‑20-like fungible tokens. |
| TransferNftParams | Parameters for transferring NFTs (ERC‑721 / ERC‑1155 on EVM chains). |
