Since you are already supported LTC and you probably run litecoin node, may I ask if there a chance you can add support for Litecoin mweb addresses on your exchange?
This will increase overall privacy and you could be one of the first exchanges to add support for mimble-wimble in Litecoin.
Litecoin Core wallet already supports ltcmweb addresses, another wallet is forked ElectrumLTC.
