Icon LinkCreating a wallet from a private key

A new wallet with a randomly generated private key can be created by supplying Option<Provider>.

use fuels::prelude::*;
 
// Use the test helper to setup a test provider.
let provider = setup_test_provider(vec![], vec![], None, None).await?;
 
// Create the wallet.
let _wallet = WalletUnlocked::new_random(Some(provider));

Alternatively, you can create a wallet from a predefined SecretKey.

use std::str::FromStr;
 
use fuels::{crypto::SecretKey, prelude::*};
 
// Use the test helper to setup a test provider.
let provider = setup_test_provider(vec![], vec![], None, None).await?;
 
// Setup the private key.
let secret = SecretKey::from_str(
    "5f70feeff1f229e4a95e1056e8b4d80d0b24b565674860cc213bdb07127ce1b1",
)?;
 
// Create the wallet.
let _wallet = WalletUnlocked::new_from_private_key(secret, Some(provider));

Note: if None is supplied instead of a provider, any transaction related to the wallet will result in an error until a provider is linked with set_provider(). The optional parameter enables defining owners (wallet addresses) of genesis coins before a provider is launched.
