Nubank restored cryptocurrency deposits and withdrawals in Brazil at 10 p.m. on Friday after an external data provider disruption halted services on November 6. The digital bank said its own infrastructure was not responsible and that customer assets and information remained protected, while other cryptocurrency products continued operating normally. Mercado Pago, MercadoLibre’s financial services business, temporarily blocked some transfers to external wallets after a provider responsible for transaction-risk monitoring and anti-money-laundering controls experienced problems. Incoming deposits could also be delayed, with pending funds to be credited automatically once systems recovered; the company had not publicly confirmed full restoration in reports dated November 7. Neither company identified the provider, and there was no confirmation that the incidents involved the same company. Both have previously worked with Paxos, but that relationship does not establish its involvement. The disruptions show how external screening, compliance and custody services can interrupt crypto access even when underlying blockchain networks continue operating. The incidents followed a separate Mercado Bitcoin security breach on November 2 involving approximately $48.5 million in suspicious transfers and Binance’s $6.3 billion hack, after which withdrawals were suspended before gradual restoration on November 1. MercadoLibre’s 2025 annual filing had already warned that failures at external cryptocurrency providers can restrict trading, custody and transfer functions.
