The Permanent Identifier for Sustainable Finance Disclosures
Every framework, SPO, impact report, and certification gets a permanent, content-based identifier — AI-indexed, version-tracked, and permanently citable. The infrastructure layer that makes labelled bond documentation machine-readable and audit-ready.
When issuers restructure their websites, the framework your investment committee relied on disappears. The SPO that justified the green label returns a 404. Impact reports that should demonstrate allocation vanish within four years of issuance.

How XFID Works
Identify
Every document receives a permanent ID computed from its content. Two copies of the same document, anywhere in the world, produce the same XFID.
Track
XFIDs link documents to issuers, bonds, analysts, and assessment providers. Version changes are detected and recorded automatically.
Cite
Reference XF-A3B7K2M-9 in an investment memo, regulatory filing,
or term sheet. The ID resolves permanently at xframework.id/XF‑A3B7K2M‑9.
Built for Every Participant in the Labelled Bond Market
Defend your due diligence
