Background and Impact
At 13:45 on November 2, 2026, Odaily Planet Daily reported that Brazilian cryptocurrency exchange Mercado Bitcoin had confirmed a security incident and temporarily suspended user deposit and withdrawal services, while stating that customer assets were unaffected. The report said that blockchain security firm Hypernative had previously detected suspicious transfers exceeding $40 million across multiple blockchain networks; according to local media outlet BitNotícias, the abnormal fund flows may be related to this security incident.
At 15:47 the same day, PANews reported that Mercado Bitcoin had published the destination addresses for outbound fund transfers related to the incident, involving the EVM, BTC, SOL, XLM, and TRON networks, and stated that the addresses were published solely for identification and tracking purposes. The platform has not yet disclosed the scale of the assets involved, nor has it provided a timeline for restoring services.
Key information remains to be confirmed between the two reports: what Hypernative detected was suspicious transfers exceeding $40 million, and BitNotícias said they may be related to this security incident, but Mercado Bitcoin has not disclosed the scale of the assets involved, so the $40 million cannot be directly regarded as a confirmed loss. As for whether customer assets are completely unaffected, the materials contain only the platform's own statement, with no independent verification information; the purpose of the platform's publication of the involved addresses is also limited to identification and tracking.
In terms of impact, the suspension of deposits and withdrawals will directly affect fund inflows and outflows for Mercado Bitcoin users. The involved addresses cover the EVM, BTC, SOL, XLM, and TRON networks, and the related fund flows involve multi-chain tracking. For users following platform entry points such as Huobi HTX registration APP download, Zhima Gate.io registration APP download, Bitget registration APP download, Binance registration APP download, and OKX registration APP download, the information currently verifiable about this incident still centers on three points: the suspension of deposits and withdrawals, the publication of the involved addresses, and the absence of a restoration timeline; the next milestones are whether the platform discloses the scale of the assets involved and a timeline for restoring services.
