#### Note

Read implemented and pollable before building against a driver. implemented false is a registry stub whose vendor contract is not verified; pollable false means the gateway has no merchant-readable status API, so its callback is the only channel and a lost callback is a lost payment. min_amount is the PSP's own floor in major units, and 0 means no floor.
