Verification methodology
Every badge on this site states exactly how much evidence sits behind it. We would rather show a weak tier honestly than imply a verification we did not perform.
| Tier | What it proves | Evidence required |
|---|---|---|
| Tier 0 · Observed | Compiled from public sources. Nobody has claimed this record. | No proof — treat as a lead, not a verification. |
| Tier 1 · Self-attested | Someone proved control of the wallet and asserts it belongs to this entity. | Wallet signature over a usd.net linking message. |
| Tier 2 · Domain-verified | Authority over the entity's corporate domain was also proven. | Wallet signature plus a verified corporate-domain email. |
| Tier 3 · vLEI-verified | Backed by an official GLEIF trust-chain credential. | Qualified vLEI issuer credential. Coming soon — not yet issued on usd.net. |
How a Tier 1 signature is checked
- The browser builds a fixed message: the address, the LEI and an ISO timestamp. No transaction is created and no approval is requested.
- The wallet signs it with
personal_sign. The signature never leaves the request in which it is submitted. - The server recovers the signing address using EIP-191 recovery and rejects the link unless it matches the claimed address exactly.
- Signatures older than 30 minutes are rejected, so a captured message cannot be replayed later.
- The LEI is re-fetched from GLEIF at link time. Links to LEIs that do not exist are refused.
What a badge does not mean
- It is not a KYC, sanctions or AML check on the entity or its counterparties.
- It is not a statement that the entity is solvent, licensed or trustworthy.
- It is not authorisation to pay. Confirm payment addresses through an independent channel every time — this registry is corroboration, not a control.
- Demo-flagged records exist to populate the registry while it is new. They are always labelled and never presented as verified.
Common questions
Does a verified badge mean the company authorised the wallet?
No. Tier 1 proves someone controls the private key and asserts a relationship to the entity. Only Tier 2 adds evidence of authority over the corporate domain, and only Tier 3 relies on a GLEIF trust chain.
Where does the entity data come from?
The GLEIF Global LEI Index, queried live and cached. Legal name, jurisdiction, legal form, registration status and next renewal date are mirrored from that record, never edited by us.
How do I remove a wallet I linked?
Open your dashboard from the same browser you signed with and delete the link. Removal is immediate on the public pages.
What happens when an LEI lapses?
The entity page shows a lapsed badge and existing wallet links keep their tier but are visibly flagged. A lapsed LEI means the registration was not renewed, not that the company disappeared.
