Hello all:

I have been working on an exchange for nxt coins to bit coins and vice versa.  I have been using the nxt coin api to integrate with sending coins to our account.  As it stands right now to get the nxt coins in the user is required to submit a form informing us they sent us the coins to an account we generate for them.  This of course creates a dummy transaction in a pending state that we can use to poll against the nxt client to see if they in fact sent us any coins or not.  In looking at some of the other exchanges that take nxt coin, with the exception of dgex, it seems all the user has to do is send the coins to the account.  I am wondering if anyone could shed some light on if there is an industry standard way of doing this, if anyone else has created any sort of cryptocurrency exchanges involving nxt I would like to know if there is any one preferred method of depositing the coins into their trding account.
