Web3 security platform Immunefi has surpassed $100 million in total payouts to ethical hackers since its launch in December 2020, according to new reporting from The Block. Immunefi runs bug bounty programs for crypto and DeFi protocols, paying whitehat hackers to disclose critical vulnerabilities before they can be exploited. The milestone underscores both the scale of security threats in the Web3 ecosystem and the growing role of structured incentives to encourage responsible disclosure. Immunefi has positioned itself as a leading bug bounty and security coordination layer for blockchain projects, connecting tens of thousands of security researchers with hundreds of protocols and protecting user funds across major DeFi and Web3 platforms. Its model typically ties bounty size to the potential value at risk, leading to some of the largest single bug bounty payouts in software history, including multi‑million‑dollar rewards for critical vulnerabilities in high‑value protocols. Crossing the $100 million paid mark signals that security spending via formal bounty programs is becoming a normalized, large-scale line item in crypto, reflecting ongoing concerns over exploits and the industry’s attempt to move from reactive crisis negotiations with hackers toward proactive, incentive-aligned defense.
