Overview

This guide shows you how to import existing Ethereum private keys into Dynamic’s MPC wallet system. This is useful when migrating from traditional wallets or integrating with existing systems.

​
Prerequisites

​
Import Your Private Key

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

const evmClient = await authenticatedEvmClient();

const wallet = await evmClient.importPrivateKey({
  privateKey: '0xYourPrivateKey' as `0x${string}`,
  chainName: 'EVM',
  thresholdSignatureScheme: ThresholdSignatureScheme.TWO_OF_TWO,
  password: 'your-secure-password'
});

console.log('Wallet imported:', wallet.accountAddress);
console.log('Public key:', wallet.publicKeyHex);

​
Security Considerations

  • Private Key Format: Must be 64 hex characters with 0x prefix
  • Password Security: Use a strong, unique password
  • Key Storage: Never store private keys in plain text after import
  • Backup: Ensure you have a secure backup of your original private key

​
Threshold Signature Schemes

Choose based on your security and availability needs:
  • TWO_OF_TWO: Maximum security, requires both server and Dynamic
  • TWO_OF_THREE: Balanced security and availability
