Provenance & Authenticity
Every Grail, Verified
Each L.S.3.1st piece carries a numbered, on-chain certificate of authenticity — permanently bound to its physical patch. Scan it in AR, claim it by email, and keep a tamper-proof record of ownership for as long as the chain exists.
Numbered Editions
Every colorway is a numbered, limited release. Each unit ships with its own edition number recorded on-chain at mint — and the archive itself keeps growing as new sneaker, fashion and culture moments are added.
AR Graphic Scanning
Point your phone at the printed monogram graphic. MindAR recognizes the artwork and unlocks the certificate linked to that exact physical item.
On-Chain Record
Certificates live on Base — the same EVM-compatible network used by major brands for product authentication. Public, verifiable, permanent.

The Process
How Verification Works
- 01
Receive Your Piece
Every garment carries a sneaker-, fashion-, or culture-inspired monogram model from the Open Archive — each a direct tribute to a specific silhouette, colorway, collab, or moment. The L.S.3.1st artwork is applied as an ultra-high-resolution DTG / DTF graphic print intentionally designed to visually mimic the texture and materials of a real embroidered patch — simulated stitching, thread sheen, merrowed borders and twill backing baked into the artwork. Each piece is uniquely numbered and tied to a single certificate ID. Physical embroidered patches are reserved for select future colorways and limited collections.
- 02
Scan In AR
Open the camera on the colorway page or hit the AR button. Our MindAR tracker matches the printed monogram in under a second and surfaces its on-chain record.
- 03
Claim By Email
First-time scan? Enter your email to claim ownership. We send a one-time link — no wallet, no seed phrase, no crypto knowledge required to start.
- 04
Optional: Bind A Wallet
Want it fully on-chain? Add a wallet address later and we'll mint the certificate to it on Base. Until then, the email claim is fully valid proof.
- 05
Transfer Or Verify
Selling or gifting? Future owners can re-claim by scanning the printed monogram and providing proof of transfer. The chain keeps the full history.
Common Questions
FAQ
Do I need crypto to own one of these?
No. The claim flow is email-first. Your certificate is valid the moment you claim. Wallets are optional and can be added later.
What blockchain do you use?
Base — an Ethereum Layer 2 backed by Coinbase. Low fees, fast confirmations, and the same network used by major fashion and consumer brands for digital product passports.
Is this the first blockchain-authenticated clothing brand?
No — and we don't claim to be. On-chain authentication has been used by Nike, LVMH, Prada, Adidas and others since 2021. What's distinctive is the combination: an open, ever-growing archive of numbered streetwear, AR patch scanning, and a friction-free email claim — at independent-drop scale.
What if I lose access to my email?
If you've bound a wallet, the wallet is the source of truth. If not, contact support with proof of purchase and we can re-issue claim access for the same physical piece.
Can I verify a piece before buying secondhand?
Yes. Ask the seller to share the certificate page — every cert has a public verify URL showing edition number, current claim status, and transfer history.
