- In Tycho Router - Fix integration tests - If the trade is cyclical, we can't do the balance check for the correctness of the amountOut transfers - In encoding, - if it is a wrap trade, the transfer should be just a normal Transfer (not TransferFrom nor a Permit2Transfer) - add test names to println! statements --- don't change below this line --- ENG-4315 Took 1 hour 0 minutes Took 30 seconds Took 21 seconds Took 16 seconds Took 17 seconds
