 The payment code shall be prefixed with `paycode:`, and can be optionally suffixed with offchain communications networks it supports in URI, e.g. `?xmpp=johndoe@something.org&matrix=@john123:something.com`. If no additional suffix is detected, the default offchain relay method, a necessity for version 2, 4, 6 and 8, is Ephemeral Relay service (see below).
