Currently the hashing scheme for txs, which is used as witness and signed by user's L2 key, still seems to be buggy. Like:
In transfer and redraw tx, the hashed amount is divided by 1,000,000 (a hard coded magic number)
Nonce is not really being hashed in redraw tx
Old balance is planned to be involved in redraw tx, but I consider this is not a good idea because deposit and spotTrade both can change the current balance at any time and make the signed redraw tx invalided
Witness of order input lack of any fields for prohibiting aggregator replaying them (like put one order to multiple open slots)
