RE: Streaming Swaps Coming Soon to LeoDex. What to Expect?

You should go to discord and tech support.

Open a ticket there and they will help you.
You will need information on the transaction and a complete written description of what you were doing.
You can get the exact information you need from the Hive-Engine website.
Sign in using Keychain and then go to the token Leo in your wallet and then to transactions, the last symbol in the list.
Then find your transaction sending Leo to Arb Leo.
Then click on the symbol at the end of the line listing your Leo to Leo Arb transaction. And a box will open with all the information you need.
Copy this and then go to your ticket and paste this information into it.
If you need more help, the person answering your ticket in discord can also help you find the information.
If you have questions about what I have written here ask me.
This is a little complicated, but you can learn it and you will have a better understanding of the blockchain afterwards.
The Inleo team will always take good care of you, so try not to stress. It may take a little time, but you will get your Leo back.
