Recently, I have been trying out a certain on-chain banking application, and the surprise is that it supports directly applying for a U card on the chain. To be honest, the entire process was quite smooth. From account verification to card generation, there were basically no complicated steps, which is indeed a new experience for those accustomed to traditional banking card application processes. More importantly, once the card is activated, it can be used directly on the chain, saving many intermediate steps. I have tested a few transactions, and the speed and stability are quite good. If you are also interested in innovative applications like on-chain banking, this direction is definitely worth following up on.
