Function Signature

recoverEncryptedBackupByWallet(params: {
  accountAddress: string;
  walletMetadata: WalletMetadata;
  password: string;
  walletOperation: WalletOperation;

}): Promise<ServerKeyShare[]>

​
Description

Recovers and decrypts backup shares for a wallet. Returns the recovered shares — the SDK no longer caches them internally. Assign the return value to a local variable if you need to reuse the shares.

​
Parameters

​
Required Parameters

  • accountAddress (string) - The wallet address (must include 0x prefix). Must match walletMetadata.accountAddress.
  • walletMetadata (WalletMetadata) - The cached metadata for this wallet. Must include externalServerKeySharesBackupInfo.
  • password (string) - Password to decrypt the backup
  • walletOperation (WalletOperation) - The wallet operation that drives the recovery shape (which shares to recover)

​
Optional Parameters

  • shareCount (number) - Number of shares to recover (defaults to 1)

​
Returns

  • Promise<ServerKeyShare[]> — Array of recovered plaintext shares

​
Example

import { authenticatedEvmClient } from './client';
import { WalletOperation } from '@dynamic-labs-wallet/node';

const evmClient = await authenticatedEvmClient();

const walletMetadata = JSON.parse(await redis.get(`wallet:${accountAddress}`));

const recoveredShares = await evmClient.recoverEncryptedBackupByWallet({
  accountAddress,
  walletMetadata,
  password: 'user-password',
  walletOperation: WalletOperation.SIGN_MESSAGE,
  shareCount: 1,
});

console.log('Recovered shares count:', recoveredShares.length);
