On July 23, three major DeFi protocols lost a combined $35.5 million within just six hours, highlighting the growing importance of crypto infrastructure security. This report reviews what happened, what these incidents reveal about today’s security landscape, and why building resilient protection systems has become a shared responsibility across the entire crypto industry.
On July 23, three separate security incidents resulted in approximately $35.5 million in losses within just six hours.
Although the affected projects belonged to different ecosystems, they shared one important message. Security is not a challenge unique to any single protocol, platform or architecture. It is a responsibility shared across the entire crypto industry.
As blockchain technology continues to evolve, so do the methods used by attackers. Every new layer of infrastructure—from bridges and validators to wallets and cloud services—creates new opportunities for innovation, but also new responsibilities for protecting users.
Rather than focusing on which project was attacked, these incidents encourage a more important discussion:
How can the industry continue building a safer environment for everyone?
| Protocol | Estimated Loss | Root Cause | Current Status |
| AFX Trade | $24.15M | Third-party bridge infrastructure | Negotiating with attacker |
| Verus Ethereum Bridge | $7.54M | Bridge import mechanism exploited | Investigation ongoing |
| B² Network | $3.86M | Investigation ongoing | Investigation ongoing |
Although the three incidents affected different projects, they revealed a common pattern: None resulted from failures of Bitcoin, Ethereum or Arbitrum themselves. Instead, attackers exploited supporting infrastructure such as cross-chain bridges and off-chain verification systems.
The industry’s infrastructure has become increasingly interconnected and so have the security challenges that come with it. As crypto continues to evolve, security must evolve alongside innovation.
Every innovation brings new opportunities and new responsibilities.
Whether assets move through decentralized protocols, centralized platforms or cross-chain infrastructure, protecting users increasingly depends on the strength of the systems supporting them.
The events of July 23 highlight three areas the industry continues to strengthen.
Security is no longer a feature added after products are built. It has become a core part of building sustainable crypto infrastructure.
Every major security incident leaves behind valuable lessons. Over the past several years, the crypto industry has continuously strengthened its security standards by investing in:
While no platform can eliminate every risk, each improvement helps raise the overall security standard for the entire ecosystem.
Security is not a destination. It is an ongoing process of learning and improvement.
Every major incident reminds the industry that preparation matters more than reaction.
At WEEX, security has always been approached as a long-term commitment rather than a short-term response. Our security framework combines transparency, operational resilience and continuous investment to help protect user assets.
Security is not something users should only think about after an incident. It should be something they can rely on every day.
No matter which products or platforms you use, protecting your assets should always remain the first priority.
Understand how a platform protects user assets before depositing funds.
Verify wallet permissions and smart contract addresses carefully.
Be cautious of products promising unusually high returns.
Diversify assets and avoid relying on a single protocol or platform.
Evaluate transparency, operational practices and security infrastructure—not just features or returns.
Security works best when platforms, developers and users all play their part.
The events of July 23 remind us that security is never a one-time achievement, it’s an ongoing commitment. Every incident pushes the industry to build stronger infrastructure, greater transparency and better protection for users.
At WEEX, that commitment guides every investment we make in security, because putting users first is the foundation of a stronger crypto ecosystem.
