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