TL;DR:
- Total amount committed: According to data from DeFiLlama, the crypto ecosystem has recorded losses of $16.521 billion so far in 2026.
- Asset transition: Immunefi will integrate the client base and the “wardens” researcher community of Code4rena following the latter’s closure.
- Impact on DeFi: Of the total capital committed this year, $7.741 billion corresponds specifically to decentralized finance protocols.
The Web3 security company Immunefi reported that it will hire the researchers and absorb the clients of Code4rena (C4), a platform that announced the progressive cessation of its commercial operations. With this action, the company seeks to consolidate security infrastructure during a period marked by a high incidence of vulnerabilities in smart contracts.
Today, we're announcing that Immunefi is partnering with @code4rena to onboard their bug bounty customers to our platform following Code4rena's decision to wind down operations.
Code4rena played a huge role in shaping crypto security, and they deserve real recognition. As they… https://t.co/fRJrXz5JUH

Consolidating security in the face of Code4rena’s closure
The Code4rena platform, known for its “competitive audit” model where independent researchers compete to find flaws, will close its doors permanently. Given this situation, Immunefi will step in to integrate the so-called “wardens” (security researchers) and ensure that projects under C4’s protection are not left defenseless.
The firm indicated that the transition will include specialized assistance to migrate reward systems, participation rules, and the scope of current projects. According to Immunefi’s report, the platform has facilitated more than $135 million in bug bounty payments to date, a figure that could climb with the addition of Code4rena’s talent.
Regarding the environment in which the migration is taking place, data from DeFiLlama at the close of the first quarter of the year indicates that the Total Value Locked (TVL) in DeFi shows high sensitivity to security failures. Analysts from the source suggest that the professionalization of triage and mediation services is now a priority for maintaining institutional trust.
The exploit landscape in 2026
The integrity of digital assets has been compromised so far in 2026. Industry data indicates that the total value committed in security incidents reached $16.521 billion. Within this volume, total losses for the decentralized finance (DeFi) sector have been 47%, which translates to $7.741 billion.
The current trend indicates that exploits are now more frequent; in April 2026 alone, more than 20 significant incidents were recorded. According to data from the source, this increase in malicious activity justifies the need for more robust bug bounty platforms with greater technical response capacity.
The integration of Code4rena into Immunefi will provide the latter with access to one of the most extensive “whitehat” communities in the sector. Market data suggests that this union could improve response times to new threats, as the unified platform will feature a greater diversity of researchers specializing in smart contract audits.
