Icon LinkConnecting to the Testnet or an external node

We can interact with the Testnet node by using the following example.

use std::str::FromStr;
 
use fuels::{crypto::SecretKey, prelude::*};
 
// Create a provider pointing to the testnet.
// This example will not work as the testnet does not support the new version of fuel-core
// yet
let provider = Provider::connect("beta-4.fuel.network").await.unwrap();
 
// Setup a private key
let secret =
    SecretKey::from_str("a1447cd75accc6b71a976fd3401a1f6ce318d27ba660b0315ee6ac347bf39568")
        .unwrap();
 
// Create the wallet
let wallet = WalletUnlocked::new_from_private_key(secret, Some(provider));
 
// Get the wallet address. Used later with the faucet
dbg!(wallet.address().to_string());

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

faucet-beta-4.fuel.network Icon Link

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 Testnet 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:

let _provider = Provider::connect(format!("127.0.0.1:{port}"))
    .await
    .unwrap();
