I’m not getting this, what do you mean by crypto real world transaction, is there anything as such? Real world transactions are like fiat.. That means a physical form transaction with cash.

But if you talk of online or digital form of transaction, then it has to do mobile transactions (mobile banking, PayPal, skrill,) and crypto transactions (Bitcoin, Ethereum etc.). So there is nothing like a crypto real world transaction, crypto is just crypto and nothing else.
