# Usage Example Wallet

```
const aptosWeb3 = require('@martiandao/aptos-web3.js');
const walletClient = new aptosWeb3.WalletClient();
async function main() {

    // create new wallet (10 test tokens airdropped by default)
    console.log("\n=== Wallet Creation ===");
    const wallet = await walletClient.createWallet();
    const address = wallet['address key'];
    const signingKey = wallet['code'];

    console.log('Address:', address);
    console.log('Secret recovery phrase:', signingKey);

    // airdrop test tokens
    console.log("\n=== Airdrop ===");
    await walletClient.airdrop(wallet['code'],5000);
    console.log('Balance:', await walletClient.getBalance(address));

    // transfer tokens
