IIP-029: Receipt-backed settlement

IIP-029 Roadmap Record

IIP-029: Receipt-backed settlement is an IOI roadmap implementation record for the sas.xyz surface. It is marked Gated in Q4 2026 and belongs to the Demand track. The canonical scope is: Outcome services marketplace for Service-as-a-Software..

Surface Context

This IIP should be read as part of the sas.xyz roadmap, not as a replacement for source papers or product pages. The parent surface gives the broader context for why this milestone exists, what it depends on, and which IOI surfaces it supports. IIP-029 depends on the hypervisor, wallet, agentgres surfaces before it can fully mature. It does not currently unblock another surface directly, but it still contributes to the cumulative roadmap record.

Canonical Relationship

This page is the canonical implementation record for IIP-029, while the parent roadmap surface and linked research pages remain the canonical sources for broader product and protocol context. Internal links point here when the milestone status, phase, dependencies, or evidence trail for Receipt-backed settlement matters.

Roadmap Role

IIP-029 exists to clarify roadmap status, implementation scope, and evidence relationships. Technical concepts flow through this page to canonical research pages, while product or runtime context flows to the relevant surface page. This preserves a complete implementation trail without making roadmap records compete with deeper IOI papers.
