const importedWallet = importBscWalletFromMnemonic(
  'your twelve word mnemonic phrase here'
);

Cosmos Wallet

import { generateCosmosWallet } from '@stochain/wallet-sdk';

// Generate new wallet
const wallet = await generateCosmosWallet('cosmos');
console.log(wallet.address);

console.log(wallet.mnemonic);

Transaction Management

import {
  fromMnemonic,
  getBalance,
  sendTransaction
} from '@stochain/wallet-sdk';
import { ethers } from 'ethers';

const provider = new ethers.providers.JsonRpcProvider('YOUR_RPC_URL');
const wallet = await fromMnemonic(['your', 'mnemonic', 'words'], provider);

// Get balance
const balance = await getBalance(wallet);

// Send transaction
const tx = {
