Basel, Switzerland — Cryptographic provenance for physical art

The art certificate that can't be forged. Because it's part of the artwork.

Prove.art bonds a bank-grade cryptographic chip to the work itself. Any buyer, anywhere, taps it with their phone and sees the verified record — artist, history, ownership. No app. No paper. No doubt.

In the demo, we tag a sample work live — you verify it from your own phone within the first five minutes.

The problem with provenance

Right now, somewhere, a certificate with a gallery's name on it is being photocopied.

Your certificate is your reputation — and it's paper.

A certificate of authenticity is only as trustworthy as the paper it's printed on. Scanned, reprinted, and attached to a copy, it puts your name behind a forgery.

Due diligence kills momentum.

A serious buyer's advisor asks for provenance documentation. Days pass. Emails. Scans of scans. The deal cools while everyone waits for paper to prove what a tap could prove in two seconds.

Provenance dies at the first private sale.

The chain of custody breaks the moment a work changes hands outside your gallery. Ten years later, at auction, nobody can reconstruct it — and the work is worth less because of it.

The art market loses an estimated $4–6 billion every year to forgery and misattribution. Not because experts fail — because records do.

Why prove.art

Paper can be forged. Databases can be disputed. The record should live on the work itself.

Paper certificate Online / blockchain registry prove.art
Physically bound to the artwork No No Yes — tamper-evident chip
Can be copied or reattached to a fake Easily The certificate is real; the link to the object is not No — removal destroys the chip
What the buyer needs to verify Trust An account, an app, a lookup Any phone. One tap.
Survives private resale Rarely If someone updates it Travels with the work, always

Digital certificates solved forgery of the record. They never solved the real problem: proving the record belongs to this object. prove.art closes that gap physically.

How it works

Three steps. Then it's permanent.

I

The chip is bonded to the work

A physically unclonable NFC chip is discreetly attached to the artwork — conservation-safe mounting, invisible placement, reversible options for sensitive works. It cannot be moved to another piece: removal destroys it, and a work that has "lost" its chip flags itself.

II

The provenance is sealed

Artist, title, date, exhibition history, prior ownership, certificates — cryptographically signed and written to the chip and to the Swiss-hosted record. Chip and record are inseparable; neither is valid without the other.

III

Anyone verifies. Anywhere. Instantly.

The buyer taps the work with any NFC smartphone. No app, no account, no reader hardware. In under two seconds: verified artist, full history, current ownership status — with your gallery's name confirming it.

Questions we hear from every gallerist

Before you ask.

Does the chip damage the artwork?

No. Mounting is conservation-safe and placement is discreet — typically the stretcher bar, frame, or verso, never the surface. For sensitive or historical works we offer reversible mounting reviewed with conservators.

What if someone removes the chip and puts it on a fake?

They can't. The chip is tamper-evident: removal destroys it electronically. And because the record notes that the work is tagged, a work missing its chip flags itself as compromised.

Can I tag works I already own or hold in inventory?

Yes. Retroactive tagging is the most common starting point for galleries — most partners begin by tagging existing inventory in a single session.

What if I have more works than my plan includes?

Nothing stops. Tag as many works as you need — additional tags beyond your yearly allowance are billed per tag (CHF 18 on Artist; on Gallery, at the rate we agree with you), or you can move up a plan at any time. Works already tagged stay verified forever, regardless of your plan.

What happens to the records if prove.art disappears?

We are building prove.art so that the answer never depends on trusting us: the domain and record archive are being placed under an independent Swiss association dedicated solely to their continuity, every owner will receive a signed, independently verifiable copy of their record, and records are timestamped in a public ledger. Ask us about the current status — we walk every partner through the continuity plan in detail.

Who controls what a buyer sees?

The owner. Public verification shows authenticity, artist, and title; ownership details and history are disclosed only at the level the owner chooses.

Does verification work without internet?

Verification requires a connection — every tap is confirmed live against our servers, which is precisely what makes it trustworthy: the result you see is the current, authoritative record, not a cached copy that could be stale or spoofed. Any mobile or Wi-Fi connection is enough, and verification takes under two seconds.
