Making the
open
methods payable allows for natives to trivially be used in user requests. Native payment can easily be accounted for alongside ERC-20 tokens by using address(0). Adding thepayable
modifier will make it much easier for integrators to account for native payments. This logic also follows forfill
, as fillers might need to provide native payment to the settlement contract to fulfill the user's order. It seems like an anti-pattern to require handling native payment in functions outside of the spec.
