Sponsor supported token checkout fees only where the token and route allow it.
Fee Delegation lets merchants configure sponsored-fee policies for supported permit-based token flows. Unsupported tokens fall back to normal wallet payment.
Fee Delegation is a policy and execution model for supported gasless token payments. It requires merchant policy activation, a compatible deployed router, relayer configuration, and a token that supports permit-style approvals.
