```
    // mainnet 
     const web3 = new Web3('https://fsc-dataseed1.fonscan.io:443');
```

### Set up account <a href="#set-up-account" id="set-up-account"></a>

If the installation and instantiation of web3 was successful, the following should successfully return a random account:

```
    const account = web3.eth.accounts.create();
```

### Recover account <a href="#recover-account" id="recover-account"></a>

If you backed up your account private key, you can use it to restore your account.

```
    const account = web3.eth.accounts.privateKeyToAccount("$private-key")
```
