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

Deep Tide TechFlow news: On May 30, DxSale released a statement about a recent security incident, saying the vulnerability was caused by a compatibility issue between the newly launched Atomic Transaction feature on BNB Chain and early v1 lock-up contracts.

The team said the affected contracts are the v1 lock-up contracts deployed in 2021. The team has completed issue identification and analysis. According to the official statement, lock-up contracts of v2 and above are not affected. The relevant contracts have been audited by CertiK, and the locked assets are secure.

DxSale emphasized that, at present, lock-up funds in all subsequent versions such as v2 and v3 have not been impacted by this incident. The vulnerability’s impact is limited to the early v1 architecture.

Previously, an on-chain security community disclosed that DxSale was allegedly involved in the withdrawal of funds from more than 1,400 liquidity pools due to contract backdoors or permission issues, involving assets of approximately $7.3 million, which drew broad attention in the market. In response, DxSale’s latest reply attributed the incident to the exploitation of vulnerabilities brought about by BNB Chain’s atomic transaction mechanism, rather than the existence of security flaws in the lock-up system of later versions.
