<p>Before you begin, ensure you have the following:</p>
<ul>
<li><strong>Foundry</strong>: Install from the <ahref="https://book.getfoundry.sh/getting-started/installation"target="_blank"rel="noopener noreferrer">official Foundry book</a></li>
<li><strong>Ethereum Wallet</strong>: A private key for Status Network testnet</li>
<li><strong>Testnet ETH</strong>: You'll need Status Network testnet ETH<!-- -->
<ul>
<li>Get Status Network testnet ETH from our <ahref="/tools/testnet-faucets">Faucet</a></li>
</ul>
</li>
<li><strong>Basic Knowledge</strong>: Familiarity with Solidity and command line</li>
</ul>
