Nubank, a crypto-friendly bank, has applied for a banking license from the U.S. Office of the Comptroller of the Currency (OCC) as it aims to expand its services into the U.S. market. If approved, Nubank plans to offer deposit accounts, credit cards, loans, and digital asset custody services. The bank, which introduced a cryptocurrency transfer function last year, currently supports Bitcoin, Ethereum, and Solana networks for crypto transactions.
