Implementation Issues:
When thinking about validation, it is clear that we cant use EVAL_ASSETS for the locked coins as there wont be any enforcement of the gateways locking. This means we need a way to transfer assets into gateways outputs and back. It seems a tokenconvert rpc will be needed and hopefully that will be enough to make it all work properly.
Care must be taken so that tokens are not lost and can be converted back
Care must be taken so that tokens are not lost and can be converted back.
This changes the usage to require tokenconvert before doing the bind and also tokenconvert before doing a withdraw. EVAL_GATEWAYS has evalcode of 251
The gatewaysclaim automatically converts the deposit amount of tokens back to EVAL_ASSETS.
