In GSN meta tx, is there a way for the user to specify in their offchain signature a value like:
That will skim a small amount of tokens off of their tx and pay them to the msg.sender; the account that is relaying their transaction?
If not then you guys missed a HUGE opportunity and I really really hope that you add this feature in your standards. This would allow relayers to collect fees in terms of tokens and even set minimum fees in order to stay profitable and be totally decentralized.
This way you can ditch centralized paymasters all together !!! Relays would only relay a tx if they are being paid enough # of the ERC20 tokens.
