Nubank Pauses Crypto Transfers and Speeds Up Its AI Agents
Hey Digital Banking Fanatic!
Two Nubank stories caught my attention, and they show two very different sides of running a digital bank.
First, Nubank temporarily suspended crypto deposits and withdrawals on Friday. It blamed instability at an external data provider, said the issue isn't in its own infrastructure, and says all customer assets remain protected. Its other crypto products kept working.
A social media post linked the pause to a hacker attack on a provider, but that hasn't been confirmed, and no provider has been named. Mercado Pago also suspended crypto deposits.
Second, Nubank shared how it tests its AI agents on simulated customers before they reach real ones. Synthetic customers with different profiles hold full conversations with the agents, so changes can be checked first.
The result: a new agent version now takes 4.4 days on average, down from 21.2 days. In offline tests, unnecessary handoffs to human support fell from 22.4% to 16.0%.
What links the two is trust. Customers expect their crypto and their customer support to just work, and at Nubank's scale, small problems reach a lot of people.
Of course, the crypto pause was still ongoing at the time of writing, so let's see how quickly it's resolved.
Here's what else is happening in digital banking today👇
See you tomorrow!
Cheers,
