Exporting WaaS Private Key

You can securely export the private key for a WaaS wallet account. For that, you’ll need to specify an HTML element to be used to inject an iframe containing the private key.

Usage

JavaScript

import { exportWaasPrivateKey, isWaasWalletAccount } from '@dynamic-labs-sdk/client/waas';
import { client } from './client';

const exportPrivateKey = async () => {
  const walletAccounts = client.wallets.getWalletAccounts();
  const walletAccount = walletAccounts[0];

  if (!isWaasWalletAccount(walletAccount)) return;

  await exportWaasPrivateKey({
    walletAccount,
    displayContainer: document.getElementById('display-container'),
  });
};

// Add a container in your UI to inject the iframe
// E.g: <div id="display-container"></div>

React

Use a ref to pass the DOM element to exportWaasPrivateKey:

import { exportWaasPrivateKey, isWaasWalletAccount } from '@dynamic-labs-sdk/client/waas';
import { getWalletAccounts } from '@dynamic-labs-sdk/client';
import { useRef } from 'react';

function ExportPrivateKey() {
  const containerRef = useRef<HTMLDivElement>(null);

  const handleExport = async () => {
    const walletAccounts = getWalletAccounts();
    const walletAccount = walletAccounts[0];

    if (!walletAccount || !isWaasWalletAccount(walletAccount) || !containerRef.current) return;

    await exportWaasPrivateKey({
      walletAccount,
      displayContainer: containerRef.current,
    });
  };

  return (
    <div>
      <button onClick={handleExport}>Export private key</button>
      <div ref={containerRef} />
    </div>
  );
}

Error Handling

• If the specified wallet account is not a WaaS WalletAccount, it will throw an NotWaasWalletAccountError error.
