Immunefi takes over Code4rena’s ‘wardens’ — Can DeFi survive 2026 exploit surge?

The competitive auditing and bounty platform Code4rena (C4) has announced plans to shut down. Amidst this, Immunefi, a Web3 security company, is stepping in to support the platform by absorbing its clients and security researchers.  For perspective, Code4rena is well-known for its "competitive audit" model, in which independent researchers, called "wardens," compete to identify vulnerabilities in smart contracts in exchange for compensation. Code4rena announced plans to wind down operations Given that Code4rena significantly influenced the development of crypto security, the shutdown is therefore a significant step.  Remarking on the same, Immunefi took to X and noted,  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. That said, the onboarding will give ImmuneFi access to one of the biggest communities of top-tier whitehats in the cryptocurrency space.  Additionally, the platform will also gain from professional mediation and triage services. The same have facilitated more than $135 million in bounty payments. Furthermore, ImmuneFi will get specialized assistance to ensure a seamless transition of C4 rules, reward systems, and scope. 2026 has already become the year of scams This occurs in the midst of widespread fraud and exploits in 2026. During this time, DeFiLlama reported that the total value compromised had reached $16.521 billion, with the total value compromised in DeFi coming in at $7.741 billion.  As AMBCrypto previously reported, over $600 million was drained in nearly 30 incidents in April alone.  Therefore, as crypto exploits continue to increase, Immunefi's intervention emphasizes the growing significance of security infrastructure. Final Summary Immunefi supports the decision of Code4rena to shut down, taking over the platform's clientele and security researchers in the process. A total of $16.521 billion had been compromised, of which $7.741 billion was compromised in DeFi.
