I see the ideal exchanger as follows:
Select the exchange direction
BTС - USDT (solana)
Enter your BTС wallet address
Then there are 2 options: AML verification was successful, continue the exchange or AML verification was not passed, we cannot perform the exchange
it will be even more ideal if the refund process is automatic and doesn't require the technical department to get involved if the exchange input doesn't pass the AML verification.
