const result = await HardwareSDK.cardanoGetPublicKey(
  connectId,
  deviceId,
  params,
);

Params​

Optional common params

Exporting single public key​

  • path - required string | Array<number> minimum length is 1. read more
  • showOnUKey - optional boolean determines if address will be displayed on device. Default is set to true
  • derivationType - optional CardanoDerivationType enum. determines used derivation type. Default is set to ICARUS=1

Exporting bundle of public keys​

  • bundle - Array of Objects with path, showOnUKey fields

Example​

Return public key of first cardano account:

HardwareSDK.aptosGetPublicKey(connectId, deviceId, {
  path: "m/1852'/1815'/0'/0/0",
  showOnUKey: true,
});

Return a bundle of public keys for multiple cardano accounts:

HardwareSDK.cardanoGetPublicKey(connectId, deviceId, {
  bundle: [
    { path: "m/1852'/1815'/0'/0/0" }, // account 1
    { path: "m/1852'/1815'/1'/0/0" }, // account 2
    { path: "m/1852'/1815'/2'/0/0" }, // account 3
  ],
});

{
    success: true,
    payload: {
        path: Array<number>, // hardended path
        serializedPath: string,
        publicKey: string,
        node: HDPubNode,
    }
}

Error

{
    success: false,
    payload: {
        error: string, // error message
        code: number // error code
