Security company Blockaid said that the AFX Trade vulnerability resulted in the extraction of approximately 24.15 million USDC's, which is a preliminary estimate of the damage caused by the intrusion of an Arbitrum based trading platform. The figure was provided by Blockaid, which flagged the incident as an attack on AFX Trade and pointed out that the stolen amount was approximately 24.15 million USDC-stablecoins pegged to the dollar issued by Circle.
This platform was identified as AFX Trade in relevant reports. CoinDesk reported that the Arbitrum based platform lost approximately $24 million after the bridge key was leaked. AFX Trade admitted the matter on its official X account, but preliminary reports did not mention the platform's specific response measures or the progress of any recovery work.
Why the reported losses are estimates rather than final figures
The stolen amount was described as "approximately 24.15 million USDC units" rather than final confirmation data. Early reporting of security incidents usually starts with preliminary estimates, and numbers may change as forensic investigations deepen. Since the USDC is pegged to the U.S. dollar, the scale of reported losses can directly correspond to the value of the U.S. dollar, making it easy for people to understand the impact of this incident. However, readers still need to distinguish this preliminary estimate from the final confirmation total that may be released subsequently by AFX Trade or the investigating party.
Blockaid plays the role of monitor here, responsible for issuing alerts rather than confirming the platform's own accounts. The company has previously provided real-time protection integrations in other parts of the ecosystem, including a collaboration with TRON DAO on real-time security.
What does this vulnerability mean for DeFi users
The reported breach immediately raised questions about the risk of exposure to funds from AFX Trade users and the risks of the platform. The bridging key leak mentioned by CoinDesk points to infrastructure risks rather than a single trading position failure. Bridging and cross-chain infrastructure have been key targets in the DeFi space, and the security status of these systems continues to attract regulatory attention, including officials weighing how to classify DeFi vaults.
Currently, the most critical next step is to wait for AFX Trade or other major sources to confirm the exact amount, the controls that have been taken, and whether the funds are likely to be recovered. Until these details are released, the figure of 24.15 million USDC units should be considered a preliminary estimate.
