Parameters

​
Required Parameters

  • keyShares (any[]) - Array of key shares

Example

import { authenticatedSvmClient } from './client';

const svmClient = await authenticatedSvmClient();

const offlinePrivateKey = await svmClient.offlineExportPrivateKey({
  keyShares: [
    {
      chainName: 'solana',
      keyShare: '0xYourKeyShare',
    },
  ],
  derivationPath: "m/44'/501'/0'/0'", // Solana derivation path
});

console.log('Offline Private Key:', offlinePrivateKey);

​

try {
  const offlinePrivateKey = await svmClient.offlineExportPrivateKey({
    keyShares,
    derivationPath: "m/44'/501'/0'/0'",
  });
  console.log('Offline private key exported successfully');
