Nubank Pauses Brazil Crypto Deposits, Withdrawals on Provider Issue

By Daniel Okafor

Nubank paused cryptocurrency deposits and withdrawals for customers in Brazil on Friday, Nov. 6 after an issue involving an outside service provider, interrupting both directions of customer crypto transfers.

In a statement Friday, Nov. 6, Nubank said: "Customer assets and information were protected." The company also said "the issue was unrelated to its own infrastructure" and did not put customer security at risk. The cited statement did not describe a loss of customer funds or any unauthorized transactions.

Nubank serves about 120 million customers in Brazil, giving the interruption potential reach across a large retail user base. That total describes the platform’s customer base, not the number of accounts affected by the pause, which the company did not disclose.

What has stopped?

The pause applies to deposits, which move crypto into a customer’s account, and withdrawals, which move it out. Customers therefore cannot use either route to bring crypto onto Nubank or take crypto off it while the restrictions remain in place.

Nubank said its other cryptocurrency products continued to operate normally. The announcement describes a targeted interruption rather than a shutdown of the fintech’s crypto business, although it did not identify the other products or explain how the remaining functions work around the paused transfers.

What caused the disruption?

The company placed the disruption with an outside provider and said its own infrastructure was not involved. Operationally, that means an external issue can interrupt a customer-facing function without implying a failure of Nubank’s core systems or a compromise of customer records.

Nubank did not disclose the provider’s identity, the nature of the issue or the number of affected customers. The announcement also gave no restoration time, leaving users without a stated timetable for when deposits or withdrawals would return.

The missing details matter for risk assessment. A total customer base of about 120 million indicates potential reach; without an affected-user count or a technical explanation, neither the scale of the interruption nor its underlying technical cause can be measured from the announcement.

What does this say about security?

Nubank separated the security question from the service disruption. Its statement said assets and information were protected and the issue did not put customer security at risk, but it did not quantify how many transfer attempts were interrupted or specify any assets involved.

That means the disclosed problem is availability, not a reported compromise of customer funds or records. The statement did not claim that every customer experienced the interruption, and it did not say how transfer requests were handled.

What happens next?

Any resolution depends on the unidentified provider and Nubank’s restoration of the two functions. The useful next disclosures would identify the provider, quantify affected accounts, explain the interruption and set a recovery timetable; none of those details appeared in the Friday statement.

With no restoration deadline disclosed, the near-term change is operational rather than market-wide: Brazilian customers cannot deposit or withdraw crypto through Nubank while the pause lasts, even as its other cryptocurrency products remain available.
