@ivarojha I have an idea to solve this problem. Why don't you ask your users to prepay 5x or 10x the platform fees, say 25k sats or whatever amount suits your requirements and then collect the escrow amount separately whenever the users want to trade? Let us say on average you charge 5k sats as platform fee per trade, the user can make 5 transactions with the prepaid amount. This will help you solve the UTXO problem as the platform fee for several trades is paid to you as a single transaction. This is just my suggestion and I am not sure if my suggestion would address your problem. If it helped, just let me know.
