AFX Trade, a decentralized trading protocol built on the Arbitrum network, has suffered a major security breach. The attack resulted in the loss of about 24.15 million USDC, which is worth around $24 million.
Blockchain security company Blockaid detected the exploit and quickly alerted the crypto community. According to the initial investigation, the attack targeted a bridge operated by AFX Trade. The incident did not affect the Arbitrum blockchain itself. Instead, the problem came from a third-party bridge managed by the protocol.
The news has once again raised concerns about the security of bridges that connect different blockchain networks.
What Happened During the Attack?
The exploit took place on July 22, 2026. Blockaid reported that it detected suspicious activity at 9:30 PM UTC.
The attacker found a weakness in the bridge operated by AFX Trade and used it to remove approximately 24.15 million USDC from the protocol.
Soon after the theft, blockchain investigators began to track the movement of the stolen funds. The quick response allowed security companies to monitor every major transaction made by the attacker.
Although the attack happened very quickly, blockchain records made it possible for experts to follow the path of the stolen assets.
The Money Moved to Ethereum
After taking the USDC from the bridge, the attacker transferred the funds from Arbitrum to the Ethereum network.
Blockchain security company PeckShield reported that the stolen USDC was later exchanged for 12,467 ETH.
The value of the converted Ethereum was close to $24 million, matching the amount taken from the bridge.
Researchers also traced the ETH to a single wallet address as they continued their investigation.
This movement of funds is common after major crypto thefts because attackers often try to move assets across different blockchain networks.
Arbitrum Was Not Hacked
One important fact became clear soon after the incident.
The Arbitrum blockchain itself was not hacked.
Steven Goldfeder, Chief Executive Officer of Offchain Labs, the company behind Arbitrum, confirmed that the exploit came from a third-party protocol.
He explained that the transaction originated from AFX Trade’s own bridge and that the official Arbitrum native bridge remained secure.
This statement helped calm concerns among users who feared that the entire Arbitrum network had suffered a major security failure.
Blockaid Responded Quickly
Blockaid played an important role after the exploit.
The blockchain security company detected the suspicious activity almost immediately and began to coordinate with the Arbitrum team.
Early detection gave investigators a chance to understand what had happened and begin tracking the stolen funds before they moved farther across the blockchain ecosystem.
Security firms often work together during incidents like this because blockchain transactions remain visible to everyone.
This public record helps investigators follow stolen assets even after they move between networks.
Why Crypto Bridges Face High Risk
Crypto bridges allow digital assets to move from one blockchain to another.
These systems help users access different blockchain networks without selling their assets.
Although bridges provide useful services, they have also become popular targets for hackers.
A bridge usually controls large amounts of digital assets. If attackers discover a weakness in its software, they may steal millions of dollars within a short time.
Because of this risk, bridge security has become one of the biggest concerns in decentralized finance.
Experts continue to encourage stronger security checks before new bridge systems go live.
July Sees More Crypto Security Incidents
The AFX Trade exploit has added to a growing list of crypto attacks this month.
According to security reports, this incident became the 14th crypto security event recorded during July.
Hack losses for July have already reached about $97 million, which is higher than the roughly $75.32 million reported during June.
These numbers show that cybercriminals continue to target cryptocurrency projects despite improvements in blockchain security.
Every major attack reminds developers that security must remain a top priority.
Investigation Is Still Underway
The investigation into the exploit continues.
Blockaid, PeckShield, the Arbitrum team, and other blockchain experts are working to understand exactly how the attacker exploited the bridge.
At the time of the latest reports, AFX Trade had not released full technical details about the vulnerability.
Investigators hope their findings will help prevent similar attacks in the future.
Each major exploit provides valuable information that developers can use to improve security across decentralized finance projects.
What This Means for Crypto Users
The incident reminds crypto users that blockchain technology remains secure only when every part of the system receives proper protection.
Large blockchain networks such as Arbitrum may remain safe, but third-party applications built on top of those networks can still face security problems.
This difference is important because many users do not always know whether they interact with the blockchain itself or with another protocol.
Experts often advise users to research projects carefully before moving large amounts of digital assets through bridges or decentralized finance platforms.
Strong security audits, trusted developers, and clear communication all help reduce risk.
The Road Ahead
The AFX Trade bridge exploit, which resulted in the loss of approximately 24.15 million USDC, has become one of the largest crypto security incidents of July 2026. Security company Blockaid detected the attack, while PeckShield tracked the stolen funds after the attacker moved them to Ethereum and exchanged them for 12,467 ETH.
Officials have confirmed that the exploit affected AFX Trade’s bridge, not the Arbitrum native bridge, which continued to operate normally.
As investigators continue their work, the incident serves as another reminder that security remains one of the biggest challenges in decentralized finance. Stronger protection, careful code reviews, and regular security testing will remain essential as the crypto industry continues to grow and attract more users around the world.
