A new wallet with a randomly generated private key can be created by supplying Wallet.generate.
import { Wallet, WalletLocked, WalletUnlocked } from 'fuels';
// use the `generate` helper to make an Unlocked Wallet
const myWallet: WalletUnlocked = Wallet.generate();
// or use an Address to create a wallet
const someWallet: WalletLocked = Wallet.fromAddress(myWallet.address);Alternatively, you can create a wallet from a Private Key:
// unlock an existing wallet
let unlockedWallet: WalletUnlocked = lockedWallet.unlock(PRIVATE_KEY);
// or directly from a private key
unlockedWallet = Wallet.fromPrivateKey(PRIVATE_KEY); You can obtain an address to a private key using the Signer package
const signer = new Signer(PRIVATE_KEY);
// validate address
expect(wallet.address).toEqual(signer.address);
