Did you know that BuildBear now helps you find bugs in your smart contracts?By using our platform, you can take advantage of our recent partnership with CredShield, which enables vulnerability scans through SolidityScan on all contracts deployed to your personalized Testnet.To learn more about this exciting development, check out our recent announcement with CredShield <a href="https://medium.com/buildbear/announcement-credshields-and-buildbear-integration-making-web3-secure-4f0dbe6b392e">here</a>.In this article, we’ll walk you through the steps of getting your contract audited using BuildBear.Let’s beginStep 1: Create a Hardhat project.If you’re new to this process, you can refer to the hardhat documentation <a href="https://hardhat.org/tutorial/creating-a-new-hardhat-project">here</a>. Once you’ve created your project, navigate to the contract folder and add your contract code, or use the smart contract provided <a href="https://github.com/BuildBearLabs/Tutorials/blob/main/hack.sol">here</a>.<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*vQlVjDSH4MGZnqvsLDwZZQ.png" alt="" loading="lazy"></figure>Step 2: Creating a Testnet using BuildBear.If you’re new to BuildBear, please refer to our guide on <a href="https://www.notion.so/8e561563dd2e410c969874ba3c1684ee">how to create a Testnet using BuildBear</a>.Once you’ve created your Testnet, the next step is to add BuildBear to your networks.Click on Verify Contracts<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:688/1*DvGLVJDTdxsFVEmnRgOHAw.png" alt="" loading="lazy"></figure><figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*9sUtUiQ_PqS1V2OvS83nGw.png" alt="" loading="lazy"></figure>To add BuildBear to your networks, you’ll need to copy the first code and add it to the <code>networks</code> object in your <code>hardhat.config.js</code> or <code>hardhat.config.ts</code> file. Similarly, you'll need to copy the second code and paste it into the same file.Now that your Testnet is set up and BuildBear is added to your networks, let’s move on to step 3.Step 3: Deployment and contract verification.Navigate to the <code>scripts</code> folder and create a new file called <code>verify.js</code>. Add the verification code after the contract deployment scripts, using a format similar to the following:<pre><code class="language-javascript">const { ethers } = require('hardhat');
async function main() {
 const [deployer] = await ethers.getSigners();

 console.log("Deploying contracts with the account:", deployer.address);
 const Contract = await ethers.getContractFactory("Hack");
 const contract = await contract.deploy();
}
await run(`verify:verify`, {
 address: contract.address,
 });

main()
 .then(() =&gt; process.exit(0))
 .catch((error) =&gt; {
 console.error(error);
 process.exit(1);
 });</code></pre>To tell Hardhat to connect to BuildBear Testnet, we can use the <code>--network</code>parameter when running any task, like this:<pre><code class="language-javascript">npx hardhat run scripts/verify.js --network buildbear</code></pre>After the successful verification of the contract, you will see this.<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*1q1RKcMc5M0T05G7S-fKIw.png" alt="" loading="lazy"></figure>Click on the link provided in the terminal that will redirect you to the contract page you can view the <code>vulnerability count</code> and <code>Solidity score</code> directly on the contract page, as shown below: <a href="https://explorer.buildbear.io/Voluminous_R5-D4_40b9e510/address/0x926cA0443dAD6E16e319E18F152d575DEEA32221">contract Page</a><figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*XmGUSA6rTT-aMiXuPFovMA.png" alt="" loading="lazy"></figure>Clicking on the links provided in the <code>Vulenerability Count</code> or <code>Solidity Score</code> will take you to the SolidityScan page which will provide you with the details. Screenshot below:<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*rhKk21ACjmfye6FWl5rpiA.png" alt="" loading="lazy"></figure>To access more details about the vulnerability, click on “view detailed results” and sign up on SolidityScan. Select Verified Contracts, enter the contract address, select BuildBear, and enter the Node ID (which can be found on the home page). Click on “Start Scan” to initiate the scan.<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:706/1*L1lsGf1JP5LxQ_JReyyM_w.png" alt="" loading="lazy"></figure>After the scan is complete a detailed report is generated as shown below.<figure class="image image_resized" style="width:679.997px;"><img src="https://miro.medium.com/v2/resize:fit:699/1*WsBPvsOL3h2Po-K9m85QHA.png" alt="" loading="lazy"></figure>In conclusion, getting your contract audited is crucial to ensure its security and reliability. With BuildBear’s integration with CredShield, you can easily deploy your smart contracts to a customized Testnet and have them scanned for vulnerabilities through SolidityScan.<blockquote>What are you waiting for Use <a href="http://buildbear.io/">Buildbear.io</a> and get your contracts audited now.</blockquote>&nbsp;
