Summary
Code4rena, a competitive smart contract auditing platform, announced on May 13, 2026, that it will cease operations. Immunefi, a Web3 security firm, will absorb Code4rena's clients and security researchers. All ongoing contests and bounty programs will be completed as planned, with existing engagements properly concluded. Code4rena was known for its competitive audit model, where independent researchers competed to find smart contract vulnerabilities. The shutdown follows a challenging period for decentralized finance (DeFi) protocols, with over 20 crypto exploits reported in April 2026, the highest monthly count on record. Analysts from JPMorgan noted that ongoing security issues in DeFi are hindering institutional investment in the sector. The total value locked in DeFi protocols has dropped from approximately $160 billion in October 2025 to about $83 billion currently. Key Points: • Code4rena announced its shutdown on May 13, 2026, with Immunefi taking over its clients. • The closure follows a record number of crypto exploits in April 2026, impacting DeFi security. • Total value locked in DeFi has significantly declined from $160 billion to $83 billion.
