Mars Finance news, Castle Labs' latest research report points out that the infrastructure for crypto "onchain banks" 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 stablecoin-linked cards achieving an annual transaction volume of $3.5 billion. The stablecoin payment platform RedotPay has surpassed an annual payment volume of $10 billion. Additionally, 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 aligning with traditional new banking (Neobank) models from payment, savings, and lending scenarios.
