Sign Typed Data

This method allows users to sign typed data using their MPC wallet.

Method Signature

async signTypedData(config: SignTypedDataConfig): Promise<string>

Parameters

config: SignTypedDataConfig - An object with the following properties:

• network: Network (required) - The network used for transactions. You can use the Network enum to specify the network.
• data: string (required) - The raw data you get from dApps or WalletConnect.
• walletToken: string (required) - The wallet token of the wallet to sign the typed data for.
• refreshToken: string (optional) - The refresh token for authentication. Use this if you want to allow SDK automatically refresh the wallet token.

Returns

Promise<{signature: string, walletToken?: string, refreshToken?: string}> - An object containing the signature of the typed data, and the new wallet token and refresh token if the refresh token is provided.

Example Usage

const signature = await sdk.wallet.sign.signTypedData({
  network: Network.ETHEREUM,
  data: '0x', // Replace with actual typed data
  walletToken: 'your-wallet-token',
  refreshToken: 'your-refresh-token' // Optional
});
console.log(signature);

Response Example

{
  "signature": "0x7e335fd65539e5c6c726be97f93e3e69019d899969d21023d2c6da51622a817d016c2e036a06b734d6de93f01a63e49460d783af8d2eb467d95a487e2028f9751c",
  "walletToken": "your-new-wallet-token",
  "refreshToken": "your-new-refresh-token"
}

Additional Information

• This method requires a valid wallet token in the SDK configuration.
• The network parameter is required to determine which blockchain network's signing algorithm to use.
• The data parameter should contain the raw typed data message you receive from dApps or WalletConnect.
