A live authenticity badge on your product pages

Two lines of HTML on your product page, and your customers see the live status of the product's certificate of authenticity, verified against the SealTrust registry, with a link to the public product passport.

Verified by SealTrust

Authentic product · Sac Cuir Edition Limitee · Maison Veritas

Checked Jul 27, 2026, 3:28 AM UTC

Three steps

1
Paste the script
Add the async script tag anywhere on your product page. It loads once, after your content. It never blocks rendering.
2
Drop the badge div
Place a div with your product identifier (uid_hash, token_id or certificate number) where you want the badge to appear.
3
Done: the badge is live
The badge shows the certificate's live status (authentic, revoked, expired) and links to the public product passport. Revocations propagate in under a minute.

The snippet

Replace YOUR-PRODUCT-ID with the product's uid_hash, token_id or certificate number.

Attributes

Everything is configured with data attributes on the div.

Attribute	Values	Description
data-sealtrust-badge	uid_hash · token_id · certificate number	Required. The product identifier the badge verifies: the same identifiers accepted by the public API and the passport page.
data-lang	en (default) · fr	Language of the badge text.
data-theme	light (default) · dark	Badge theme, to match your product page.

FAQ

Does it slow my page down?: No. The script is async (about 2 KB, no dependencies) and the badge itself is a lazy-loaded iframe rendered on SealTrust's servers. Your page renders first, the badge fills in after.
What about my visitors' privacy?: The badge sets no cookies and sends no visitor data. The iframe is loaded with referrerpolicy="no-referrer", so not even your page URL is transmitted. The only thing SealTrust receives is the product identifier you put in the div.
What happens if a certificate is revoked?: The badge switches to an explicit warning state within a minute (statuses are cached for at most 60 seconds). Unknown identifiers show a neutral "product not recognized" state, and network errors degrade silently. The badge never fakes a verification.
Where does it work?: On any HTML page: Shopify, WooCommerce, PrestaShop, custom storefronts. If your product list is rendered client-side, call window.SealTrustBadge.scan() after inserting new badge divs.

Every badge is a proof, and a doorway
