Crypto projects are facing unprecedented security threats in 2025, with over $3.1 billion already lost to hacks this year.
On 31 July, blockchain security firm Immunefi launched Magnus, an AI-powered platform designed to offer real-time protection against these threats.
Backed by a growing need for smarter defence systems, Magnus is being positioned to safeguard more than $180 billion in assets across decentralised finance (DeFi) protocols such as Arbitrum, zkSync, and Curve Finance.
Immunefi’s new platform aims to plug critical vulnerabilities as they emerge, reflecting a growing trend of integrating artificial intelligence into blockchain infrastructure for preventive security.
As DeFi adoption accelerates and cross-chain integrations become more common, security breaches are rising in both frequency and complexity.
Crypto hacks in 2025 already exceed $3.1B
According to blockchain security company Hacken, the total value of funds lost in crypto-related attacks this year has already reached $3.1 billion.
This figure includes both direct protocol exploits and phishing campaigns, affecting individual investors and large projects alike.
In response to this growing risk, Immunefi’s Magnus platform aggregates multiple monitoring tools into a unified security interface.
This centralised approach allows for instant alerting and faster threat resolution, especially during live exploit attempts when immediate action is required.
Magnus is compatible with several industry-standard monitoring solutions and does not require protocols to abandon their preferred tools.
Instead, it consolidates their threat intelligence and offers a collaborative dashboard, minimising the time between identifying a threat and acting on it.
Codexa AI scans blockchain vulnerabilities in real time
At the core of Magnus lies Codexa, Immunefi’s proprietary AI-based tool. Codexa operates as a continuously evolving database of smart contract vulnerabilities.
It is designed to monitor blockchain networks in real time, analyse threat patterns, and issue alerts before threats materialise into full-scale exploits.
Codexa draws from security disclosures, bug bounty reports, and public exploit databases to detect known vulnerabilities across protocols.
This approach enables Magnus to act proactively, not reactively, when a threat surfaces on the blockchain.
The platform is being deployed across ecosystems that together represent over $180 billion in total value locked.
Arbitrum, zkSync, and Curve Finance are among the protocols integrating with Magnus, according to Immunefi.
Immunefi steps up amid pressure to secure DeFi
The launch of Magnus comes at a time when investor confidence in DeFi is being tested by recurring security failures.
Immunefi, already known for hosting multi-million-dollar bug bounties, is moving further upstream in the security lifecycle—shifting from post-hack mitigation to preemptive protection.
Rather than relying solely on community bug reports or manual auditing, the firm is now offering protocols a dynamic security layer embedded within their operational infrastructure.
The integration of Codexa allows Immunefi to build an intelligence-driven model that flags threats even before they are publicly known or exploited.
Magnus also seeks to promote greater transparency and accountability by encouraging projects to maintain up-to-date threat dashboards.
While AI alone cannot eliminate all security risks, platforms like Magnus mark a shift toward automation in DeFi protection strategies.
