3D render · card to come

When an object changes hands, its story should follow.

RELICKEEPER® is a custody protocol. A Seal on the object, a card in the hand of the one who keeps it, a gesture to pass it on: from the day it is sealed, the object will carry its story with it.

Sales are not yet open. Reservations for the founding edition will open soon, ahead of the Ulule campaign planned for mid-February 2027.

The manifesto

Why RELICKEEPER exists. Subtitles available.
Read the transcript

0:00 — [Night. A dark wooden table, lit only by a phone lying flat, screen up, showing nothing. In its cold light, one by one, appear an audio cassette, a floppy disk, a vinyl record half out of its sleeve, a comic album and a game box with a painted cover, all new. Music: a high, fragile pad. On screen: "We've never owned so much."] "We've never owned so much. Music, books, games."

0:05 — [Identical copies of the same objects appear in rows, from back to front, until they fill the table.] "Everything gets copied. Nothing gets passed on. And nothing is ours."

0:11 — [On screen: "Nothing is ours." The phone screen goes dark: everything vanishes at once. Black and silence; the text remains.]

0:13 — [A switch clicks. A low lamp comes on, warm and grazing: the table is empty. A cello comes in.]

0:15 — [The RELICKEEPER card falls onto the wood with a metallic sound and settles; its shadow settles with it.] "What is yours has weight." [On screen: "What is yours has weight."]

0:19 — [Close-up on the corner of the same game box, worn: scuffed edges, a glass ring on the cover. On screen: "This one has a story." The black Seal drops into its corner with a small dry sound.] "This one has a story. Once sealed, it becomes a relic."

0:25 — [Top view: a hand slowly pushes the sealed box across the table; its shadow slides with it. The card lies beside it. A muted piano joins the cello.] "Trust can't be downloaded. It's born of touch."

0:31 — [Closer: a second hand rests flat on the box, the first withdraws. On screen: "From hand to hand." The lamp dims to black.] "From hand to hand, one keeper to the next."

0:37 — [End card: the RELICKEEPER logo in white on black, then "Trust can't be downloaded." The music fades out.] "RELICKEEPER."

The observation

We rent our images, our music, our worlds. We no longer own them.

What we still hold, a cartridge, a box, a graded card, a figurine, changes hands and takes nothing with it: not who kept it, nor when, nor how it passed from one to the next. Its provenance lives in a folder of screenshots, which mostly reassures whoever put it together. And it vanishes with them.

RELICKEEPER starts there: giving back to physical objects the memory that the digital age has taught us to lose.

The protocol

Two objects, one bond.

The Seal will be a chip placed on the object, designed to resist copying, read contactlessly by a phone. The card will stay with its keeper: it is the card that designates them, and no transmission will take place without it. The Seal will record the date of sealing and the keeper who sealed it.

One gesture, at the same table.

Each keeper will keep their own card. What will change hands is the object and its history. The holder will place their card on the phone, the new holder will place theirs, and the relic will pass from the first card to the second. As the film puts it: one does not leave without the other.

You will need the RELICKEEPER app, free to download and with no RELICKEEPER account, but no marketplace between the two of you. The vault's register will keep a time-stamped record of each transmission, the one shown in the film. In Publique mode, the time stamp will be set by the trust service provider.

The weight of a transmission will be yours to choose.

The film shows the screen “How do you want to pass on this relic?”.

  • Souveraine: from hand to hand, offline, without revealing your identity.
  • Publique: the transmission will be signed electronically with a trust service provider, with identity verification and time stamping; it will therefore go online.

The level of verification will range from Ancrage to Maximale. The keeper decides how much weight to give their gesture.

The film

The Seal and the card, in under two minutes. Subtitles available.

0:00 — [Music: analog synths. In the evening, in a flat drawn in gold line art, a woman hangs a framed art print on the wall: a tree on a hill, under the moon. On a sideboard, her phone screen lights up with a blurry photo taken in a gallery: the artist signing the print.] “A print, signed tonight, in front of you. What will be left of that moment?”

0:06 — [In an attic, among an adult’s belongings (a jacket, glasses, archive boxes), a teenager sits on the floor, an open card binder on his knees, holding a graded card in each hand and looking from one to the other.] “Thirty years of cards, in binders. If one day you were gone, it’d all go to a yard sale.”

0:12 — [At a retro video game fair, two strangers face to face, both hesitant. One holds the real B.A.T. box close, in colour, still shrink-wrapped; the other reaches out, then holds back.] “B.A.T., still shrink-wrapped: your retro-gaming grail. Facing a stranger, who trusts first?”

0:18 — [On black, the real B.A.T. box, alone.] “An object changes hands. Its story gets lost.”

0:23 — [On black, a gold title appears then fades: "The Seal".] “The Seal.”

0:26 — [The B.A.T. box on a table. The black Seal drops and settles on the corner of the box, with a gold glint. A hand brings a phone above the Seal; a cyan ring pulses around it: the phone reads it.] “A Seal. The phone reads it. The card confirms. Now it’s a relic. You’re its keeper.”

0:31 — [On black, a phone drawn in gold line art, and the real B.A.T. box floating, in colour. A hand lays the RELICKEEPER card on the top of the phone; its LED lights up and the screen glows. The B.A.T. box is drawn into the card, spinning, then dozens of other relics drawn in gold line art after it. The phone screen lights up on "My Vault" and fills, one by one, with photos of the relics. On-screen text: "Yours to keep — in one gesture." Fade to black.] “Yours to keep, in one gesture.”

0:40 — [On black, a gold title appears then fades: "The Transfer".] “The transfer.”

0:43 — [A hand holds the card against the back of a phone; the card lights up. The "My Vault" app screen appears and scrolls. Then, in close-up, the "How would you like to pass on this relic?" screen, set to Sale, Sovereign and Anchor. In the background, in half-light, two people face to face at the same table, drawn in gold line art: the holder holds the real B.A.T. box, the buyer listens. The Anchor button pulses; the Sovereign button sparkles and draws in three gold icons: two hands passing a relic, a masked bust, a crown. The screen switches to Public and Maximum; the Maximum button pulses, and the Public button, sparkling green, draws in four green icons: an ID card with a check mark, a signing pen, a PDF document, a clock. Labelled "RELICKEEPER mobile app". Back to the hand touching the phone with its card: its LEDs light up.] “The keeper opens the vault, and chooses how to pass it on.” “Between friends, hand to hand.” “For your grail, a signed transfer.” “Then signs with a single touch, without leaving the table.”

0:57 — [One hand passes the phone to another; on the table, the card and the B.A.T. box drawn in gold line art, its Seal at the corner.] “They hand over the same phone.”

1:02 — [The second hand taps its own card on the same phone; a gold button lights up. Then, large, the app screen filmed: "Transmission Sealed — The relic has a new holder", with the app’s gold and cyan fireworks; gold confetti bursts around the phone. Labelled "RELICKEEPER mobile app".] “The new holder taps their card, and confirms.”

1:09 — [One hand passes the B.A.T. box, drawn in gold line art with its Seal, to another hand, above two cards. At the same moment, the real box, small, leaves the first card and lands on the second, which glows gold. App screen: the Registry, "A timestamped record of all your transmissions", with the B.A.T. box line and its date. Labelled "RELICKEEPER mobile app". On-screen text: "A story handed down."] “A story handed down. One never leaves without the other.” “Keeper to keeper.”

1:16 — [Split screen. Left: two hands pass the real sealed B.A.T. box, its Seal at the corner. Right: two hands each touch the same phone with their card; their LEDs light up at the contact.] “Everyone leaves with what they came for.”

1:21 — [In gold line art, an adult hand places the real RELICKEEPER card in a child’s small hand; the card lights up in the palm.] “And one day, for your children.”

1:24 — [The frame widens: dozens of card pairs exchange relics, faster and faster. Each relic named passes large: a signed art print, a graded card, the real B.A.T. box still shrink-wrapped, a figurine, a speedrun record. The relics turn into gold line drawings, then spiral into a vortex of light that tightens into a white flash. The music rises and stops dead at the flash.] “On platforms, your relic loses its story. Here, it keeps it. A signed print. A graded card. A shrink-wrapped box. A figurine. A speedrun record.”

1:39 — [In the white of the flash, the RELICKEEPER logo appears in black, backlit; rays of light converge on it, it draws in the light and turns white on black; then "Memory becomes matter.", in silence. The bottom of the frame stays clear: at the end, the page shows the "Reserve my place · €5" button there.] “Memory becomes matter.”

1:43 — [The end card stays on screen.] “RELICKEEPER. Reserve your place: five euros, returned after the campaign.”

What has no body.

The vault is designed to keep the intangible, sealed without a Seal: a speedrun record you set, or an image you authored. It is designed to pass the sealed relic to the next keeper: its entry, its sealing date and its history, not the file or any right in the work or the record. The RELICKEEPER card is designed to reveal, on screen, the master of the works the gallery presents, without handing over the file or any right in the work. The gallery, under construction, shows the principle: see the reveal under the magnifier.

The transmission protocol between two RELICKEEPER cards is the subject of a French patent application, FR2607321, filed by YTY on 2 June 2026, claiming priority from application FR2515238 of 12 December 2025. It is under examination at the INPI, the French patent office, and no patent has been granted to date.

The founding edition

RELICKEEPER cards ordered before the Ulule campaign closes will form the founding edition. Each will receive a founder number, assigned in order of reservation, then in order of campaign pledges: reserve early and you hold a lower number. Your number will be guaranteed if you order your card within 72 hours of the campaign opening. A number once assigned will never be reassigned, and no card made after the campaign will receive one.

Card sales are not yet open. Reservations will open soon: for €5, you will be able to reserve your founder number and your tier, and you will be told the campaign is opening before the public announcement. Your €5 will be returned after the campaign, whether or not you order, to your original payment method, within 14 days of its end; if it has not opened by 30 June 2027, within 14 days of that date. Tiers and their indicative prices are on the shop.

The founding edition will open with an Ulule campaign planned for mid-February 2027.

A universe, an origin

RELICKEEPER comes from a game. Olivier Cordoleani wrote B.A.T. with Hervé Lange, a cyberpunk universe released at Christmas 1989. The box you see passing from hand to hand in the film is that game.

A game for the universe, a gallery for the works, a protocol for custody: one author, one house.

Frequently asked questions

What is RELICKEEPER?

A custody protocol for the objects that matter. A Seal placed on the object, which a phone will read, and a card held by its keeper. From the moment of sealing, they will keep the object's history and allow it to be passed on, with that history, from one keeper to the next.

Does RELICKEEPER tell you whether an object is authentic?

No. It will keep a record of who holds the object, and since when. The Seal will record the date of sealing and the keeper who sealed it; what came before, the object's origin and past, remains whatever its holder declares. Authenticity is a matter for experts: an object that has been appraised or graded can then be sealed.

What does it add to an object that is already graded?

A grader's mark states an object's condition at a given moment. RELICKEEPER will keep what comes after: the hands it passes through, and its history, which changes hands with it.

What happens if I lose my card?

Your relics will not be stored on the card. With your 24 recovery words, a restoration service will let you reinstall your vault on a new card; the old one will become unusable.

Do I need a platform or an account?

No RELICKEEPER account, and no marketplace between the two keepers. The RELICKEEPER app will be free to download; using it requires a RELICKEEPER card. Publique mode will go through a trust service provider.

Where will my data be?

With you, on your phone; the backup and, in Publique mode, the signature will go through third parties, described in the privacy policy before the app is released.

When will RELICKEEPER be available?

The founding edition will open with a crowdfunding campaign on Ulule, planned for mid-February 2027. Reservations will open soon; their terms are already published on the shop.
