AFX Protocol reportedly loses $24M in bridge exploit
AFX Protocol reportedly loses about $24.15 million after an exploit hit one of its crosschain bridges on Arbitrum. Security firm Blockaid flagged the attack, while Offchain Labs said Arbitrum’s native bridge was not compromised. Stolen funds were reportedly moved to Ethereum and swapped for ether.
Key Takeaways
- AFX Protocol, a decentralized perpetual exchange on Arbitrum, reportedly lost $24.15 million in a bridge exploit.
- Blockaid said it detected the exploit at 9:30 p.m. UTC on Wednesday.
- Offchain Labs said the incident involved a third-party protocol, not Arbitrum’s native bridge.
- On-chain watchers said the attacker bridged 24.15 million USDC to Ethereum and bought ETH.
- Officials described the case as under investigation, with more details still emerging.
What happened in the AFX Protocol bridge exploit?
According to Cointelegraph, AFX Protocol reportedly lost $24.15 million on Wednesday after an attacker targeted one of its crosschain bridges. AFX is described as a decentralized perpetual exchange operating on Arbitrum.
Blockaid said it detected the exploit at 9:30 p.m. UTC. The report frames the loss as tied to a bridge operated by AFX, not to Arbitrum’s core bridging system.

Did the attack compromise Arbitrum’s native bridge?
No, based on comments from Offchain Labs. Co-founder Stephen Goldfeder said the team was aware of a reported bridge hack on Arbitrum and was investigating.
Goldfeder confirmed the transaction in question originated from a third-party protocol. He also said the Arbitrum native bridge has not been hacked or exploited in any way.
That distinction matters for users who bridge assets on Arbitrum more broadly. A third-party protocol loss does not automatically mean the network’s native bridge infrastructure failed.
Where did the stolen funds reportedly go?
Lookonchain said the exploiter bridged 24.15 million USDC to Ethereum. The watcher also said the attacker bought 12,467 ETH at an average price of about $1,937.
Those on-chain movements help explain why the headline figure is often rounded to $24 million. The underlying report cites a more precise $24.15 million USDC transfer path.
Cointelegraph noted this remains a developing story. More information may be added as investigators and the protocol share further updates.
Why does this AFX Protocol loss matter for crypto users?
Bridge exploits remain one of the highest-impact risks in decentralized finance because they sit between chains and large pools of liquidity. Even when a Layer 2’s native bridge is unaffected, apps built on that network can still be hit.
Users of perpetual exchanges and crosschain tools should treat third-party bridges as separate trust assumptions from the base chain. Cointelegraph said more details may follow as the investigation continues.
The reported AFX Protocol loss underscores a familiar pattern: rapid detection, fund movement across chains, and public clarification that core network infrastructure was not the failure point.
