Aptos: get public key

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

const result = await HardwareSDK.aptosGetPublicKey(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

Exporting bundle of public keys

• bundle - Array of Objects with path, showOnOneKey fields

Example

Return public key of fifth aptos account:

HardwareSDK.aptosGetPublicKey(connectId, deviceId, {
    path: "m/44'/637'/0'/0'/0'",
    showOnOneKey: true
});

Return a bundle of public keys for multiple aptos accounts:

HardwareSDK.aptosGetPublicKey(connectId, deviceId, {
    bundle: [
        { path: "m/637'/0'/0'/0'/0'" }, // account 1
        { path: "m/637'/0'/1'/0'/0'" }, // account 2
        { path: "m/637'/0'/2'/0'/0'" }  // account 3
    ]
});

Result

Result with only one public key

{
    success: true,
    payload: {
        path: string, // hardended path
        publicKey: string
    }
}

Result with bundle of public keys

{
    success: true,
    payload: [
        { path: serializedPath, publicKey }, // account 1
        { path: serializedPath, publicKey }, // account 2
        { path: serializedPath, publicKey }, // account 3
    ]
}

Error

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