Display the badge.
If your product passes every mandatory conformance suite, you may display the official "SignedReceipts compatible" badge. The mark signals to your users that an independent test suite vetted your envelope, signing, and chain handling.
How to claim
- Pass 100% of the mandatory conformance suites in CI for two consecutive weeks. Per-suite results must be deterministic and reproducible from a public artefact.
- Publish your CI configuration and your latest signed conformance report at a stable URL — for example
your-product.com/.well-known/signedreceipt-conformance.json. - Register your signed conformance key by opening a pull request against signedreceipts/badges with the URL above and an
x-product-idfor your listing. - The working group reviews submissions weekly. Approved listings appear in /implementations/ within seven business days.

Trademark and modification
The badge mark is licensed CC-BY-ND. You may redistribute the unmodified mark; modifications, recolouring beyond contrast adjustments, or composition into derivative marks are not permitted. The trademark "SignedReceipts" and the receipt-glyph logo are owned by the SignedReceipts working group and may only be used to indicate verified compatibility.
Misuse — for example claiming compatibility without passing the suite, or using the badge on a product whose listing has been revoked — will trigger a revocation procedure documented at /governance/#revocation.
