Mercado Bitcoin to Resume Real Currency Transactions Following Cyber Attack

Following a significant security breach that resulted in the loss of approximately $49 million, the crypto exchange Mercado Bitcoin has announced plans to resume financial operations. Starting next week, customers will be able to perform deposits and withdrawals in Brazilian reais using Pix, the nation’s instant payment system. This development marks a step toward normalcy for users of Mercado Bitcoin, which is one of the largest digital asset platforms in Brazil.

Mercado Bitcoin will resume Brazilian real transactions via Pix next week following a $49 million hack.

Understanding Mercado Bitcoin operations

Access to the platform began to be restored earlier this week, initially allowing users to view their accounts in a read-only format. During this period, the exchange has directed customers to documentation regarding its security protocols and historical audits dating back to 2018, while also providing details concerning the recent incident. Fabricio Tota, the company’s vice president of new business, recently discussed the recovery process in a video update, though a formal timeline for the full restoration of services has not yet been published on the company's website.

Under the new operational guidelines, customers will be restricted to withdrawing funds exclusively to bank accounts held in their own names. Additionally, the exchange confirmed that it will credit user accounts with proceeds derived from the settlement of fixed income products. Despite these updates, all deposits and withdrawals involving cryptocurrencies remain suspended indefinitely, with no specific date provided for their return. A company representative noted that the resumption of services would be gradual, with further updates communicated through official channels.

The breach, which occurred on November 2, took place just days after a separate, larger attack on Binance where hackers stole roughly $6.3 billion in assets. In response to the theft, Mercado Bitcoin stated its intention to cover the losses by utilizing its corporate treasury and emergency fund.

Why it matters

The resumption of Pix-based transactions is a critical recovery milestone for the exchange and its client base, who have faced restricted access for over two weeks. While this change allows for the movement of fiat currency, the continued suspension of crypto-asset transfers highlights the ongoing security challenges facing major digital exchanges following large-scale cyber attacks.
