Connecting 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",
        )?;

        // 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

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

block-explorer

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?;
