Mercado Bitcoin has temporarily suspended customer deposits and withdrawals after identifying and containing a security incident, the exchange said on X on November 2, 2026. The company reported that no customers suffered financial loss and that no data was leaked, and described the suspension as a preventive protection measure while its teams investigate.
Suspicious transfers flagged, but $40M not confirmed stolen
Hypernative, a blockchain security firm, reported spotting more than $40 million in suspiciously sized transfers across roughly 10 blockchains. Mercado Bitcoin and third parties have not confirmed that the reported amount represents assets stolen from the exchange or its customers, and the company has not published a breakdown of the flagged transfers.
Mercado Bitcoin publishes destination addresses to aid tracking
The exchange said it published destination wallet addresses linked to the movements under investigation to help track and identify assets. Those addresses cover EVM-compatible chains as well as Bitcoin, Solana, Stellar and TRON, the company said.
Investigation ongoing; limited technical details released
Mercado Bitcoin said its security teams quickly contained the incident and are mobilized to investigate, trace assets and coordinate with relevant authorities. The company did not disclose further technical details about affected systems or confirm whether any of its wallets were compromised. It also gave no date for when deposits and withdrawals would resume, saying teams were working to restore operations safely.
Customers were directed to follow the platform’s official communication channels for updates on the investigation and service restoration.
