Nubank customers who hold crypto assets will be able to exchange between BTC, ETH, SOL or UNI and USDC. The feature is integrated with Nubank Cripto, which simplifies currency transactions through direct exchange, and this option supports lower fees compared to actually buying and selling in fiat currency.

Nubank customers will gradually use this feature in the coming weeks, and can exchange more token pairs "in the coming months." (Crowdfund Insider)
