Stage 1 — Neutral-assisted settlement (live).
A Neutral sets up the matter; the Payor funds; the Recipient accepts. This is what is available now.
Stage 2 — Peer-to-peer settlement (planned).
Two parties settle directly, with no Neutral. The Neutral product becomes a thin layer on top.
Stage 3 — Machine-to-machine settlement (live).
Software agents can settle programmatically through the Solis Agent API. This is the machine-to-machine direction covered by the provisional patent.
