DxSale responds to the $7.3 million security incident: only affects the 2021 v1 lock-up contract

2026-05-31 by admin

TechFlow news on May 30, DxSale issued a statement regarding the recent security incident, stating that the vulnerability stemmed from a compatibility issue between BNB Chain’s newly launched Atomic Transaction feature and the early v1 locking contract.

The team indicated that the affected contract is the v1 locking contract launched in 2021, and the problem has been identified and analyzed. According to the official statement, locking contracts of v2 and above remain unaffected, and related contracts have been audited by CertiK, ensuring the safety of locked assets.

DxSale emphasized that all locked funds in subsequent versions, such as v2 and v3, are not impacted by this incident, which is limited to the early v1 architecture.

Previously, the on-chain security community disclosed that DxSale reportedly saw over 1,400 liquidity pools drained due to a contract backdoor or permission issue, involving assets worth approximately $7.3 million, sparking widespread market attention. In response, DxSale attributed the incident to exploitation via BNB Chain’s atomic transaction mechanism, rather than any security flaw in the locking system of subsequent versions.

PANews, June 3rd — According to The Block, the U.S. Treasury Department on Tuesday imposed sanctions on Nobitex, Iran's largest crypto exchange, and three other local trading platforms as part of the Trump administration's "Economic Fury" operation targeting Iran's financial network. The Treasury's Office of Foreign Assets Control (OFAC) stated that Nobitex processed over 50% of all digital asset inflows into Iran in 2025, playing a key role in sanctions evasion, terrorism financing, and transactions linked to Iran's Islamic Revolutionary Guard Corps. Sanctions were also extended to Nobitex's chairman and co-founder, current CEO, and two other co-founders. The Treasury further sanctioned Wallex, Bitpin, and Ramzinex, accusing them of facilitating transactions for the Revolutionary Guard and other sanctioned entities. This sanction announcement came less than a week after the U.S. Treasury Secretary said the U.S. had seized approximately $1 billion in Iranian crypto assets. However, the data in Tuesday's announcement still cited the previous estimate of nearly $500 million, creating a discrepancy between the two figures.

PANews reported on June 3rd that, according to The Block, total futures trading volume on major cryptocurrency exchanges fell to approximately $2.9 trillion in May, a 12-month low and the lowest level since the end of 2023, far below the peak of $6 trillion to $7 trillion per month during last year's active trading period. Trading volume remains highly concentrated on a few exchanges, with Binance maintaining its dominant share, followed by OKX, Bybit, and Gate. Analysts suggest that against this backdrop, the CFTC's formal opening of crypto perpetual futures contracts to the US market—a derivative previously largely outside US regulatory purview—has made significant strides. Perpetual futures, with no expiration date, use funding rates to anchor contract prices to spot prices, and have become the dominant trading tool in the global crypto derivatives market. The significance of this regulatory opening lies more in institutional participation, more compliant infrastructure, and onshore liquidity free from regulatory arbitrage. The current challenge is whether regulated US exchanges can compete with offshore exchanges on margin requirements and liquidity conditions.

According to a report by The Block on June 2, the DeFi lending protocol Radiant Capital has announced it will officially cease operations. The protocol suffered a hack in October 2024, losing approximately $51 million, as attackers deployed a backdoor contract on Arbitrum and BNB Chain to gain unauthorized access. Earlier in early 2024, the protocol had also been hit by a flash loan attack, resulting in losses of around 1,900 ETH (about $4.5 million).After 18 months of recovery efforts, Radiant Capital stated it was unable to recover a significant portion of the stolen funds or successfully raise capital, and "the DAO has no viable path forward." The protocol will now enter a "maintenance state," with the frontend and smart contracts remaining accessible, allowing users to continue withdrawal, repayment, and position management operations. If any funds are recovered in the future, they will be returned to affected users.
