Deploying a smart contract on the blockchain without auditing can quickly spell “suicide” for most projects. Nowadays, hackers are constantly looking for potential code errors and vulnerabilities. Furthermore, most users have the experience of knowing they cannot trust unaudited DeFi and crypto protocols.

Fortunately, no project has to launch unaudited, especially with the abundance of professional auditors in the industry. These experts can investigate smart contracts, detect errors or vulnerabilities, and suggest fixes. Simply put, they increase a protocol’s chances of launching successfully and building community trust.

Here is a list of the top 6 smart contract auditing companies that help make the crypto ecosystem safer!
