Is it USDT on the ethereum chain?
If so:
Get it all together on one wallet.
Go to https://leodex.io/?ref=monk (delete everything after the last / if you don't want me as an affiliate).
Connect the wallet.
Swap USDT-ETH --> CACAO.
Then swap CACAO --> LEO (currently this step can't be done due to arbitrum being down on mayachain, but they will get it going again at some point).
My USDT on bybit exchange and two other exchanges
i was wondering which blockchain the USDT was. Which "type".
Probably just plain USDT which is easily traded on LeoDex. What type of wallet are you using?
