The ladder, walked

Each requirement is a binary question answerable from public state. An unknown blocks the stage exactly as a failure does — but it is shown differently, because they are different facts.

Stage 0 — The gate is observable. not reached

?
Can a stranger observe this token's transfer gate reach a decision?
unknown — not observed
✓
Does the contract answer basic ERC-20 reads, proving it is live?
yes

Stage 1 — Credential substance is checked and the terms are stated. not reached

?
Is an address holding no credential actually refused?
unknown — not observed
✗
Is the credential checked for substance — KYC, expiry — not just existence?
no
?
Are the insolvency waterfall and price basis stated on-chain?
unknown — not observed

Stage 2 — Refusals are durable and exit is proven. not reached

?
Does a refusal survive its own transaction, with the rule named?
unknown — not observed
?
Can a holder exit — redeem, or transfer to a reachable counterparty?
unknown — not observed
?
Is the issuer unable to pause, freeze, seize or upgrade?
unknown — not observed
A plain ERC-20 never claimed the standard, so it is not graded.

Conformance detail

4 passed · 9 failed · 14 not observable · 0 not applicable. Verdict NON_CONFORMANT.

Failing vectors:

Every vector cites the ERC-3643 clause it derives from, and carries its own grade for whether it can fail at all. See the ruler →

What else runs this code

This contract runs implementation 66b921341ab7f3f3 (direct, 1,895 bytes), and it is the only token here that does. Its result stands on its own.

The record an issuer can hand upward

The table answers a reader's question. This answers a supervisor's: a dated, content-addressed record of exactly what was checked, what the answer was, and what could not be checked and why — stated in the same voice as the findings, because a gap an auditor has to discover is a gap that was hidden.

It carries the sha256 of its own findings, so an edited copy stops matching. It names the block and the RPC, so it can be re-run rather than believed. And every vector in it carries the grade of the check that produced it — nobody is asked to weigh a verdict without knowing whether that check has ever been able to fail.

Download the audit record (JSON)

This is a record of transfer-control conformance. It is not an audit of the issuer, the asset, custody or reserves, and it is not a rating — the report says so itself, in its own limits section.

Re-run this yourself

The exact endpoint this measurement was taken from, so the command runs as written rather than needing a value filled in.
