As a perpetual DEX on Arbitrum, AFX previously relied on an independently operated USDC cross-chain bridge. This attack once again exposes the risks of multi-signature or verification mechanisms. Blockaid and Arbitrum's quick collaboration continues the industry's incident response model, similar to the freezing paths after earlier attacks on bridges like Gravity Bridge.

In terms of capital flow, the attackers attempted to quickly cash out across chains but face freezing risks. The project team and Arbitrum are mobilizing security resources to minimize losses, motivated by collaboration to reduce systemic risks and strategically promote Layer 2's evolution towards safer native bridges and audit standards.

After multiple DeFi bridge incidents, the industry is self-examining. Similar third-party risks are common in Japanese or Korean projects. AFX is currently at a stage of growth in Arbitrum DeFi, but the shortcomings in bridge security are becoming apparent.

Structural Judgment

This essentially relates to regulatory changes and technological substitution. Frequent bridge attacks prompt Layer 2s like Arbitrum to strengthen cooperation with security firms, accelerating the shift from third-party multi-signature bridges to native or intention-based bridges. The mechanism lies in hackers exploiting low-cost verification threshold vulnerabilities, concentrating capital in protocols with real-time monitoring and freezing capabilities, and reconstructing the security pricing power of DeFi infrastructure.

Bridges are the Achilles' heel of DeFi, and freezing is the last line of defense.
Response speed determines the extent of losses; collaboration is more vital than individual efforts.
Every attack is a paid lesson in decentralized security.
