The sealed pack
Graded PSA and BGS cards, held in a vault, tokenised one to one. Odds published as live counters. Every reveal settles on a public beacon.
Demo rip
No wallet. No email. No payment.
Same odds table, same beacon, same maths.
The demo runs tonight’s counters against a drand round that has already closed. You get the full sequence — the sealed pack, the round it points at, the reveal, the floor value of what came out. What you do not get is a card, because nothing was paid for and nothing was minted. It is the shop with the price removed, not the shop with the numbers removed.

Demo rips settle from a completed round and a frozen copy of the live counters. Nothing mints, nothing ships, nothing is charged. Rip it as many times as you like.
Odds by tier
Seven Legendary cards left out of a thousand is a number you can count.
A percentage is a number you have to take our word for.
The odds are a readout of the vault, not a table we wrote. Every card in the pool is a graded slab with a cert number, a published floor value and a tier. Add a card and the counter moves. Pull a card and the counter moves the other way. The snapshot the contract used to price your pack is written on chain before payment clears, so the distribution you bought into can be read back afterwards, line by line.
A rarity table is a claim. A counter is a receipt.

A reveal lands on one index out of 10,000. Your tier is the band the index falls in — the same bands the recompute panel prints.
Counters update as cards enter and leave the vault. The snapshot attached to your pack does not.
Pull cooldown: a slab you pulled today sits out of your draws for 24 hours, so the same card cannot land on you twice in a day.
Every pack contains at least one card. There is no empty outcome.
How a reveal is settled
Most shops draw on their own server. Some draw in your browser with Math.random().
Either way the result exists before you see it, and whoever owns the machine can run it again.
The three steps
No re-rolls
01 / CommitInside our perimeter
At checkout the contract writes down three things: the odds snapshot, the vault inventory it was derived from, and the number of a future drand round.
At that moment the outcome does not exist — not on our servers, not anywhere.
Round number sealed, outcome not yet defined
02 / BeaconOutside our perimeter
On schedule, roughly 16 independent organisations jointly produce one signed random value. The network is drand quicknet and its schedule is fixed at one round every three seconds. No single participant can steer it, and no participant is us.
The BLS signature is checked on chain before it settles anything, so a forged round simply fails.
Signed value returns, signature checked on chain
03 / RevealInside our perimeter
Relaying the round is permissionless: if we go quiet, you post the beacon yourself and open your own pack. The reveal prints the two adjacent entries in the table and the exact distance in the beacon output, so the placement can be recomputed by a stranger.
No re-rolls, for anyone. There is no mechanism for one.

The placement digest is SHA-256 over the commit, the round number and the beacon output, in that order, joined by colons. The index is the first six bytes of that digest read as one big-endian integer, mod 10,000 — the band it falls in is your tier. Two ways to get the digest, and they have to agree.

Most packs open below what you paid for them. That is what the markup is, and we would rather print it than bury it.
Also on the shelf — Table Break. One pack sold as seats to different wallets. Everyone pays first, the slots are dealt afterwards, and the table reveals together on one round. Sixty seconds to swap seats before the pack is armed.
The shop opens at mint. Until then the rip is the demo — same counters, same beacon.

Consignment note · redemption of one graded slab
01 / Redeem
Open the card in your collection and press Redeem. Enter the delivery address. The token is locked at that moment so the same card cannot be sold twice.
02 / Burn
The token is burned on chain. That burn is the receipt: it is what proves the slab left the pool rather than being quietly re-shelved.
03 / Pack
The slab is pulled from storage, photographed against the cert number, sleeved, boxed and insured for its published floor value.
04 / Ship
Tracked courier, signature required. Tracking lands in your account and by email within 5 business days of the redemption.
Shipping $19 per parcel. Multiple cards to one address ship together at no extra cost.
Import duty and local tax are the recipient’s responsibility. Customs value is the published floor value.

How the buyback offer worksScrolls sideways
| Claim | Guaranteed | Notes |

| At least one card per pack | Yes | There is no empty outcome. Stated before purchase. |
| Floor value of the pack | Yes | Published per tier before purchase and printed on the pack — $26 to $4,200 across the checklist. |
| The card is real and graded | Yes | PSA or BGS slab, cert number matches the token. |
| Physical delivery on redemption | Yes | To any of the 31 listed countries. |
| Odds snapshot cannot change after commit | Yes | Written on chain before payment clears — snapshot d7852e61…c4cbecc6, 2026-09-01 18:34:00 UTC. |
| Buyback offer | No | Discretionary. Priced at the time of the offer, and it may be reduced, paused or withdrawn. |
| Resale value on any third-party market | No | Set by that market, not by us. |
| That a pack opens above its price | No | Most do not. The markup is 4% to 15% and it is printed. |
Buyback offer — $1,040 · valid 48 hours
Discretionary. This is an offer, not a standing commitment.
No buyback offer on this card right now? You can still hold it or ship it.
Floor value
The published minimum value of the card you receive, set from graded sold comps and refreshed weekly. It is your downside, not your baseline: the floor of the worst tier in the pool is printed on every pack before you pay.
Custody
One slab in storage for every token in circulation.
No lending, no pooling, no rehypothecation.
A token you cannot redeem is a picture of a card.
Cards are held by named at mint at named at mint in a facility built for graded collectibles: climate held at named at mint, named at mint security, cards stored in their sealed holders and never removed except to ship. The holdings are insured with named at mint to named at mint. Inventory is reconciled named at mint against the on-chain supply by named at mint, and every reconciliation is published.
Cards stay in their sealed holders from intake to dispatch. We do not crack slabs and we do not regrade.
Paste any address, cert number or token id, and get the vault record back. Contract addresses, the redemption contract, and every card we custody are listed in one registry, so a lookalike site or a resold token can be checked in one step rather than trusted.
Negative result reads: not in the registry. If a site told you otherwise, it is not us.
The registry opens at mint, with the contracts.

Straight answers
The uncomfortable ones are near the top on purpose.
They are a readout of the vault, not a table we wrote. Every card carries a tier, a cert number and a published floor value, and the counter next to each tier is the literal number of slabs left — Legendary: 7 / 1,000 remaining, not a percentage. The snapshot used to price your pack is written on chain before payment clears, so you can read the exact distribution you bought into, and read it again afterwards. Add a card and the counter moves. Pull one and it moves back.
A drand round. drand is a public randomness beacon produced on a fixed schedule by a network of roughly 16 independent organisations working together; no single one of them can steer the output, and none of them is us. Your pack is committed to a round number before that round exists. When it lands, the round’s signature is verified on chain and the reveal is computed from it. Relaying the round is permissionless — you can post it yourself and open your own pack. There are no re-rolls, for anyone, including us.
Every pack contains at least one graded card — there is no empty outcome, and the guaranteed floor value of the pack is published before you pay. What varies is which card, inside a set of value tiers that are fully disclosed with live counters. It is a probability-based model over disclosed inventory, with a printed expected value and a printed markup of 4% to 15%. We say plainly that most packs open below their purchase price, because that is what a markup means. If what you want is a specific card, buy that card on the secondary market instead; a pack is the wrong instrument for it.
Yes. A pack is priced at the expected value of its contents plus a fixed markup of 4% to 15%, which means the typical pack opens below what you paid for it. The published guaranteed floor value is your downside, not your baseline. Both numbers — floor value and expected value — are printed on the pack before you pay, and the demo lets you see the distribution before any of your money is involved.
Your pack mints as a token and stays sealed. Nothing is decided at checkout. When you are ready, you arm the pack to a future drand round; until then the sealed pack is an ordinary token and you can transfer or resell it unopened. Arming is the one-way step: once a pack points at a round, that round decides it, and anyone can open it. The reveal prints the two adjacent entries in the table and the exact distance in the beacon output, so a stranger can recompute the placement.
Press Redeem, enter an address, and the token is burned on chain — that burn is the proof the slab left the pool. The card is pulled from storage in its sealed PSA or BGS holder, photographed against the cert number, double-boxed, insured to its published floor value, and sent by tracked signature-required courier. We ship to 31 countries including the United States, Canada, the United Kingdom, Germany, France, Italy, Spain, the Netherlands, the Nordics, Japan and Australia. Dispatch within 5 business days of the redemption. Import duty and local tax are the recipient’s responsibility.
Usually, and it is an offer rather than a promise. Each card shows a buyback offer with a price and a validity period; accept it and settlement lands in 24 hours with no listing and no counterparty to find. Buyback offers are discretionary: they are priced when they are made, and they may be reduced, paused or withdrawn. If there is no offer on your card at a given moment, you can still hold the token or redeem the slab and ship it.
The slabs sit with the custodian named in the Vault section above, insured to the value published there, one card in storage for every token in circulation. No lending, no pooling. Inventory is reconciled against on-chain supply on the schedule published in the same section, and every reconciliation is published.
Redemption runs against the contract, not against our front end: if the site goes dark, the redemption path and the custody agreement are what stand, and both are in the docs.
