deriveConfigPrivateKey

Derives the configuration private key from the wallet's root node. This key is used to encrypt wallet configuration data that can be synced across devices.

The key is derived from path m/5757'/0'/1, following the BIP44 recommendation for keys relating to non-public data.

Usage

import { deriveConfigPrivateKey } from '@stacks/wallet-sdk';
import { HDKey } from '@scure/bip32';
import { mnemonicToSeed } from '@scure/bip39';

const seed = await mnemonicToSeed('your 24-word seed phrase ...');
const rootNode = HDKey.fromMasterSeed(seed);

const configKey = deriveConfigPrivateKey(rootNode);
// Uint8Array — the raw private key bytes

Notes

• Returns the raw private key as a Uint8Array.
• Throws a TypeError if the key cannot be derived.
• This is called internally by deriveWalletKeys.
