We can interact with the Testnet node by using the following example.
import { Provider, WalletUnlocked } from 'fuels';
const provider = new Provider('https://beta-3.fuel.network/graphql');
// Setup a private key
const PRIVATE_KEY = 'a1447cd75accc6b71a976fd3401a1f6ce318d27ba660b0315ee6ac347bf39568';
// Create the wallet, passing provider
const wallet: WalletUnlocked = Wallet.fromPrivateKey(PRIVATE_KEY, provider);
const signer = new Signer(PRIVATE_KEY);
// validate address
expect(wallet.address).toEqual(signer.address);In the code example, we connected a new provider to the Testnet node and created a new wallet from a private key.
Note: New wallets on the Testnet will not have any assets! They can be obtained by providing the wallet address to the faucet at
Once the assets have been transferred to the wallet, you can reuse it in other tests by providing the private key!
In addition to the faucet, there is a block explorer for the Tesnet at
If you want to connect to another node just change the url or IP and port. For example, to connect to a local node that was created with fuel-core you can use:
import { Provider, WalletUnlocked } from 'fuels';
const localProvider = new Provider('http://127.0.0.1:4000/graphql');
// Setup a private key
const PRIVATE_KEY = 'a1447cd75accc6b71a976fd3401a1f6ce318d27ba660b0315ee6ac347bf39568';
// Create the wallet, passing provider
const wallet: WalletUnlocked = Wallet.fromPrivateKey(PRIVATE_KEY, localProvider);
const signer = new Signer(PRIVATE_KEY);
// validate address
expect(wallet.address).toEqual(signer.address);
