Avant.Dev Ventures · Vault
Art Certificates
Every work that leaves Avant.Dev leaves with a certificate of authenticity: frozen facts, a tamper-evident ledger, signatures backed by a verified ID, and a pass for your phone’s wallet. Yours to show. Never yours to expose.

The pass as it sits in Apple Wallet. Google Wallet carries the same certificate.
how it works
01 · issued
The gallery issues the certificate the day the work enters its Vault: the facts are frozen, hashed and written to a ledger where every entry references the one before. Nothing can be edited quietly.
02 · signed
The artist, the collector and the gallery each sign through a personal link. A signature can require a government ID verified with document and selfie, not just an email.
03 · in your wallet
The certificate becomes a pass in Apple Wallet or Google Wallet: the work, the artist, the certificate id, your stamps and a QR that opens the public page. Provenance in your pocket, offline.
04 · shared
Send it on WhatsApp or Telegram. The link unfurls as a card with the work and its stamps. Your name and what you paid are never on it; you decide what the public page shows.
05 · transferred
When the work changes hands the certificate is transferred, not reissued: the history stays whole, the new owner signs, the artist’s resale royalty is booked.
06 · offered
A collector can open a work to offers on the market. They reach the gallery, which brokers the sale and keeps the certificate’s history intact. Liquidity without losing the thread.
why this, and not paper
The formal art market keeps provenance in drawers. We keep it with the collector.
A ledger, not a letter
Each certificate is a record whose every change is hashed against the previous one. Anyone with the QR can check that the chain holds; nobody can rewrite it.
Signatures that mean something
Three parties sign, each through a personal link, each optionally with a government ID verified by document and selfie. The email alone is never enough.
Privacy by default
The public page shows the work, the artist and the stamps. The owner, the price and the history are the owner’s to reveal, switch by switch.
Royalties that reach the artist
A transfer books the artist’s resale royalty in the same ledger. The artist sees it, and so does the gallery.
Made in Mexico City, for anywhere
Avant.Dev is a gallery and a technology studio. The Vault is the part of our practice that keeps a work’s story attached to the work.
verify a certificate
Scan the QR, or type the code.
The id is printed on the document and on the pass; the code sits under the QR. Paste either, or the whole link.
