Certik is a company specializing in providing security for the web three ecosystem. They offer services such as code analysis and vulnerability discovery for smart contracts, aiming to ensure the integrity and security of projects in the web three ecosystem. Certik's reports and recommendations are publicly available, allowing the community to see the flagged issues and their remediation. They also work with projects to address vulnerabilities but solely provide recommendations rather than fixing the problems themselves. The web three ecosystem has distinct security considerations compared to web 2, with a focus on smart contracts and blockchain-related vulnerabilities. However, the web three ecosystem also incorporates elements of web 2, such as wallets and exchanges, which bring additional security concerns. Surtek plays a role in the web three ecosystem by providing security scores and recommendations for assessing project risks. There are challenges in ensuring secure coding practices in crypto projects, and the industry is encouraged to prioritize secure coding and address vulnerabilities flagged in reports. KYC is important in crypto projects to promote trust and community recognition, but it is not yet widely adopted. Overall, ensuring security in the web three ecosystem requires a comprehensive approach that considers the unique aspects and interconnectivity of both web 2 and web three components.
