WEMIX loses $6.25M in smart contract exploit as crypto hacks mount

WEMIX, the blockchain platform behind the WEMIX token, lost $6.25 million in a smart contract exploit on July 27, becoming the latest target in a punishing stretch of crypto security breaches.

"The attacker exploited a vulnerability in the protocol's smart contract logic, draining funds directly from the ecosystem's treasury," a security researcher familiar with the incident said.

The exploit targeted the WEMIX smart contract on the mainnet, siphoning $6.25 million in WEMIX tokens and other assets. The breach follows a string of high-profile crypto attacks in July, including a $24.15 million bridge hack on Arbitrum-based AFX Trade and a $7.54 million exploit of the Verus Ethereum bridge — both occurring within hours of each other on July 22, according to security firm Blockaid. A separate $3.86 million attack on the B² Network, a Bitcoin scaling protocol, was also reported that week.

The incident tests investor confidence in the WEMIX ecosystem, one of South Korea's most prominent blockchain projects, and raises broader concerns about smart contract security across the Korean blockchain sector. WEMIX token price faces potential selling pressure as the market digests the loss, with the protocol's total value locked likely to decline as users withdraw funds. The exploit adds to a year in which off-chain key compromises and smart contract vulnerabilities have drained hundreds of millions of dollars from decentralized protocols, with Q2 2026 ranking among the worst quarters for crypto hacks on record.
