I believe ISXF will start providing identity & payment services to 'Crypto exchanges' as they couldn't earlier due to ASX connections. Clearpay however, as it's still 40% owned by NSX (Listed with ASX) will have some real challenges getting ASX off their backs. While I am not a blockchain expert, commence sense would indicate that Clearpay's tech should support such exchanges. As you said it is inevitable.
