Nubank and Mercadopago Suspend Crypto Withdrawals Across Latin America

Two of Latin America's most prominent financial technology platforms, Nubank and Mercadopago, have suspended cryptocurrency deposits and withdrawals across their regional services. The companies moved to temporarily pause digital asset operations following technical disruptions linked directly to an external infrastructure partner.

According to the institutions, the sudden interruption in digital asset functionality stemmed from operational instability affecting an external data provider. Neither fintech platform indicated any internal operational breakdown within its proprietary trading interface, consumer banking systems, or core user account software.

Both Nubank and Mercadopago rely on Paxos as their third-party custody provider to handle custody, settlement, and technical infrastructure for retail cryptocurrency holdings. Because both platforms share this underlying custodial network, technical volatility or communication interruptions at the vendor level can quickly affect retail transactions across both services simultaneously.

The unexpected halt in transfers sparked widespread discussion across social media channels, where some market participants speculated about a potential security breach or cyberattack. However, no official reports or regulatory filings have been released indicating that either firm or their custody partner suffered a hack or unauthorized intrusion.

Over recent years, digital asset features rolled out by neobanks and e-commerce payment platforms have become a primary onboarding mechanism for cryptocurrency users across Latin America. Platforms such as Nubank and Mercadopago have enabled millions of retail customers to buy, store, and trade digital currencies directly within their primary everyday financial apps.

The current service pause underscores the broader fintech sector's heavy reliance on specialized third-party custody and data providers to manage custodial requirements and compliance frameworks. While outsourcing custody accelerates product deployment for major consumer apps, it also introduces centralized technical dependencies where vendor outages directly affect end-user access.

During the ongoing suspension, account holders attempting to deposit additional digital tokens or transfer their existing crypto balances off the platforms have been unable to execute transactions. Pausing deposit and withdrawal functionality is a standard risk-mitigation step taken by financial institutions during connectivity anomalies to ensure platform stability and protect balance records.

Market observers and retail users continue to await more detailed technical updates regarding the third-party instability and the steps being taken to restore normal transaction queues. Unscheduled outages in retail crypto products routinely draw public scrutiny, highlighting the importance of transparent communication during service disruptions.

For now, operations remain paused as the companies monitor systems alongside their infrastructure partners to achieve full technical stability. Customers and regional market participants will be watching for official notices from Nubank, Mercadopago, and Paxos signaling the complete resumption of transfer services.
