I remember we discussed this before. What exactly is the fee that you charge? Can you link to a few examples of Mercury withdrawal transactions so we can see what exactly they look like?

The withdrawal fee is currently 0.5% of the coin value - this is the only fee - unlimited (within the timelock constraint) swaps are free.

This is an example of a deposit tx:

and the corresponding withdrawal tx:

The fee address is currently fixed, so it is trivial to find all withdrawals:

We are working on a new feature where the fee can be paid upfront before deposit, either via a LN payment or separate bitcoin tx, enabling users to have no on-chain link to mercury.
