 ### Return Signed Orders (WIP)
 
-The UI compares all received quotes from solvers and chooses the quote from the best solver. Once the user's deposit is confirmed, the UI requests the solver for a signed order. The signer has to send back a signed order that matches with quote given (within expiry). It is important that the returned order is exclusive to the user & the UI's executor (see code). This is important since the Cross Cats UI can guarantee that the assets will be delivered through a UI controlled but user owned Bitcoin address.

 Once the signedOrder is sent & it correctly matches the expected quote, the vast vast majority of orders will be filled.
