I think this is how it works:
You can not use credit card for crypto transaction in Nigeria, CBN do not allow that. You can only use P2P in certain kind of ways. I do not know how Treasura is working but I think it is a kind of P2P that makes transaction to be instant.
I checked my Kucoin app just now and I updated it and I clicked on third-party, but I did not see Treasura. I only saw Simplex.

I think we should wait for sometimes to see if we are going to see Treasura or not. It should listed among the third-party. It deosn not require card at all, it only requires bank transfer.
