A merchant [store]@ is an account [client state] that partitions a coupon by accepting ¢ents (a charge^) in an exchange with a vendor (on a shared "peer-to-peer" router).@@ An interface. ^^ hypercurrency Merchants, in turn, residually stabilize (anchor⚓) the tempo.
/// Each merchant acts as its own UUallet host. Merchants activity is represented by inflection points (tips) on a graph of the current.

To qualify as a merchant (bank=yes), the account must transact a minimum of one (1) coupon* in any given period (2600 seconds), or else it reverts to no bank status.** Active with a value of at least one ¢ent. (see u-u economics)
/// A vendor may simultaneously be a merchant, and vice versa.
