Retrieves BIP32-Ed25529 extended public derived by given BIP32-Ed25519 path. User is presented with a description of the requested key and asked to confirm the export.

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
• showOnOneKey — 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, showOnOneKey fields

Example

Return public key of first cardano account:

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

Result with only one public key

{
    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
