The storm raging over the security of crypto exchange platforms is not abating. The Brazilian giant Mercado Bitcoin, a real pillar of the market in Latin America, was forced to urgently suspend all deposits and withdrawals after the detection of a major security incident. According to cybersecurity firms, nearly $45 million in suspicious transfers have been identified across more than ten blockchain networks.
In brief
- Mercado Bitcoin has frozen deposits and withdrawals of funds as a preventative measure following a crypto hack.
- The company Hypernative spotted around $45 million in anomalous movements spread across at least 10 blockchains.
- The crypto exchange officially claims that no user assets have been lost and that no data leaks have been reported.
Sprawling Hack Affects More Than 10 Blockchains on Mercado Bitcoin
The alert was given in the early hours of the day this Monday, November 2, 2026, by the on-chain security firm Hypernative. The latter reveals abnormal capital movements initiated from Mercado Bitcoin infrastructures. The crypto attack stands out for its extremely sophisticated nature, affecting a wide range of blockchain ecosystems.
In total, the equivalent of 45 million dollars was extracted suspiciously, instantly navigating between several major crypto networks to complicate tracing.
| Blockchain Network | Status & Impact |
| Bitcoin (BTC) | Suspicious transfers identified on dedicated wallet |
| Solana (SOL) | Siphoning liquidity to external addresses |
| Ethereum & EVM (ARB, AVAX, POL, BSC) | Coordinated movements across multiple smart contracts |
| Stellar (XLM) & Tron (TRX) | Value units moved to relay nodes |
No harm to crypto users
Faced with the emerging panic on social networks, the management of Mercado Bitcoin quickly reacted by publishing a series of official press releases in order to clarify the situation and reassure its millions of users.
We quickly identified and contained a security incident in one of our systems last night. We emphasize that there was no harm to customers and no data leaks.
As a precaution, the crypto exchange is temporarily freezing deposit and withdrawal options while the breach is isolated. In a proactive transparency move, the platform also made public the list of destination addresses used by hackers (on EVM, BTC, SOL, XLM and TRON) so that the crypto community, on-chain analysts and other platforms block any attempt to liquidate stolen funds.
This incident occurs in a context of extreme nervousness for the global crypto ecosystem, particularly after the recent Binance hack. While centralized infrastructures face repeated and increasingly complex offensives, this attack suffered by the South American leader is a reminder of the vulnerability of systems to multi-network faults.
If the rapid reaction of Mercado Bitcoin’s teams made it possible to avoid a data leak and protect its clients’ assets, the complete reopening of the withdrawal valves will be closely scrutinized by the crypto market in the coming hours. Do you have funds hosted on regional platforms like Mercado Bitcoin, or do you now favor Cold Wallets despite their security crisis?
