 `m` is the mint URL. The mint URL must be stripped of any trailing slashes (`/`). `u` is the currency unit of the token keysets (see [Keysets][01] for supported units), and `d` is an optional text memo from the sender.
 
-`i` is the keyset ID of the profs in `p`, which is an array of `Proof` objects without the `id` field. We extracted the keyset ID `id` from each proof and grouped all proofs by their keyset ID `i` one level above (in `p`).

 Note that all fields of the `bytes` type encode hex strings in the original representation of `Proof`'s.
