The largest bug bounty marketplace connecting protocols with whitehat hackers
Last updated: July 2026
Immunefi is the largest bug bounty platform in Web3, connecting protocols with a global community of whitehat hackers who are rewarded for responsibly disclosing vulnerabilities — often with the biggest bounties in all of software, sometimes reaching millions of dollars for critical DeFi bugs. Rather than a point-in-time audit, Immunefi provides continuous, always-on security: once a program is live, thousands of researchers can probe your live contracts indefinitely, with payouts scaled to severity and the value at risk. It has facilitated the prevention of enormous potential losses and manages the triage, validation, and payout process between projects and hackers. This makes it a critical complement to audits — audits before launch, bug bounties running perpetually after. The trade-offs: bug bounties are reactive by nature (someone has to find and report the bug), running an attractive program requires committing real bounty capital, and it's a complement to — not a replacement for — pre-launch audits. But for any protocol securing serious value, an Immunefi program is close to industry-standard, providing ongoing, incentive-aligned coverage from the world's largest whitehat community.
