Built by an atelier that numbers its own work.

Editioned is the Shopify app for merchants who treat each piece as an edition, not a SKU. Hosted provenance certificate per piece, EU Digital Product Passport export, no NFTs, no per-certificate fees.

Built by Guild 79

Editioned is built and maintained by Guild 79, a luxury jewellery atelier. Guild 79 produces hand-finished numbered limited editions of rings, bracelets, and necklaces through partner ateliers with long-running production relationships. No two pieces in an edition are identical. Each piece ships with a hosted provenance certificate generated by Editioned itself.

How Editioned came to exist

While building the Guild 79 storefront on Shopify, the team hit a wall: every existing app for tracking numbered editions required buyers to install a crypto wallet to view their certificate. Most jewellery customers, which is the segment Guild 79 targets, politely decline. So Guild 79 built the wallet-free version it needed for its own atelier.

After a few weeks the same problem kept showing up in other Shopify merchants' threads: how do you give buyers a verifiable certificate without putting them through Web3 onboarding? The internal tool got polished, submitted to the Shopify App Store, and published in May 2026.

What Editioned does

Editioned turns any Shopify product into a numbered limited edition with a per-piece verification token. The app provides:

• Hosted provenance certificate per edition (URL + QR code), wallet-free buyer verification
• EU Digital Product Passport JSON-LD export per edition, CIRPASS-aligned, ready before each sector's regulation deadline (batteries Feb 2027, textiles ~late 2028, electronics 2027-28)
• Six theme blocks for any Shopify Online Store 2.0 theme: edition badges, scarcity bars, remaining counters, edition trackers
• Auto-assign on order, auto-revoke on refund. No manual workflow
• Order metafields under the editioned namespace for downstream email tools (Klaviyo, Shopify Email, Omnisend, Mailchimp). Editioned does not send transactional email itself; merchants keep their existing sender, suppression list, and brand voice.
• 30-day Pro trial on every install, no card. Auto-downgrades to Free after the trial unless the merchant upgrades

The token security model

Every edition gets a cryptographic token at creation, generated with Node's crypto.randomBytes. This is the same primitive Node uses for session tokens and JWT signing, not Math.random(). Tokens are 10 characters: an hf brand prefix plus 8 random alphanumeric characters from a 36-character alphabet, giving 2.8 trillion possible combinations (36⁸). Tokens are not enumerable. Apps that use sequential IDs (/cert/1, /cert/2) leak every certificate to anyone who can iterate URLs. Editioned tokens cannot be guessed even after observing thousands of valid samples. When an edition is revoked (return, cancellation, transfer), the old token dies and a new one is generated. Old QR codes cannot be re-used to view the active certificate.

Pricing

Three plans: Free ($0/mo, 3 products / 15 editions, watermarked PDF), Pro ($49/mo, 50 products / 5,000 editions, full features), Studio ($99/mo, 500 products / 250,000 editions, all certificate styles + series drops). No per-certificate fees at any tier. A Studio merchant generating 100,000 certificates a year pays the same $99/mo as one generating 100. Every install starts with 30 days of full Pro features automatically. No card required.
