CertiK
CertiK, the largest Web3 security service provider, uses AI and formal verification to protect and monitor smart contracts and protocols, securing the Web3 ecosystem.
OpenZeppelin
OpenZeppelin is the security standard for onchain finance: the smart contracts, standards, and security services behind the industry's most critical systems.

Immunefi
Crypto and DeFi teams use Immunefi to find critical vulnerabilities before attackers do. An Audit Competition puts the code in front of Immunefi's researchers before launch, and a Bug Bounty Program keeps it there once the code is live. Managed Triage saves engineering hours by removing duplicates and spam and taking on the analysis and escalation, so the team only looks at what is really important. 93% of post-launch critical crypto vulnerabilities disclosed through bug bounty platforms come through Immunefi. Researchers on Immunefi surface more than 40 confirmed critical vulnerabilities every month.
Code4rena
After 5 years of securing DeFi, Code4rena is closing its doors. Active competitions and bounties are being seen through to completion.
