Data: As of last November, the monthly transaction volume of crypto cards has risen to a historic high of 406 million USD

Castle Labs' latest research report points out that the infrastructure for "Onchain Banks" in cryptocurrency is maturing rapidly. Data shows that by November 2025, the monthly transaction volume of crypto cards has risen to a historic high of $406 million, with Visa's stablecoin-linked cards reaching an annual transaction scale of $3.5 billion.

The stablecoin payment platform RedotPay has exceeded an annual payment scale of $10 billion. In addition, etherfi's non-custodial crypto card product Cash has contributed about 50% of the protocol's revenue, with approximately 300,000 accounts and nearly 70,000 active cards. The report believes that onchain banks are gradually moving from scenarios such as payments, savings, and lending towards a traditional neobank model.
