The rules of the sale.

1. What Slabmatic is

Slabmatic is an online marketplace for graded Pokémon cards. Every card we list is professionally graded and sealed in its slab, and every payment on this site is made in Bitcoin — there is no card, bank or wallet payment option.

We own the cards we list and we ship them ourselves. When you win an auction, buy a card at the listed price, or have a Holy Grail offer accepted, the card comes from us directly.

2. Your account

You need a Slabmatic account to bid, buy or withdraw. You can create one with an email address and password, or with Google.

You are responsible for everything that happens under your account. Keep your password to yourself and tell us straight away if you think someone else has used it.

• Your sign-in stays on the device you used, so you don't have to sign in again every visit.
• One account per person. Your balance, bids, offers, orders and chat are all tied to that account.

3. Bitcoin deposits

To bid or buy you first send Bitcoin to the Slabmatic deposit address: bc1qtcm7x9mscwmldw4tjra08nggqm6qnnt0jz089j. After sending, you tell us your transaction ID and we check it on the public Bitcoin blockchain before crediting your balance.

A deposit is credited once the network has confirmed it and we have checked that it really paid the deposit address. Each transaction ID can only ever be credited once.

• Only send Bitcoin you own and control. A deposit from a transaction you don't own will be reversed.
• Network miner fees are on you — send the full amount you want credited.
• Your deposited Bitcoin belongs to you. You can withdraw it at any time under section 7, or get it back through a refund under the Refund Policy.
• Sending Bitcoin to any address other than the deposit address above is outside our control and we cannot credit it.

4. Bidding on auctions

A bid is a commitment to pay. When you place a bid, the Bitcoin worth your bid amount must already be in your balance — if it isn't, the bid is rejected and you're told how much more to deposit.

Each new bid must be at least 5% above the current high bid. Auction listings show the current high bid and the time left.

• Bids can't be taken back once they're accepted.
• If you're the highest bidder when an auction ends, the Bitcoin for your winning bid is taken from your balance and the card ships to you.
• While you are the highest bidder, the Bitcoin covering that bid is held back from withdrawal so your win stays covered. It's released the moment you're outbid.
• Winning lots are returnable for 30 days after delivery, exactly like a buy-now card.

5. Buying at the listed price

Buy-now cards show their price in Bitcoin, with the US dollar figure as a reference at the live exchange rate. At checkout you confirm a satoshi amount, and we reject any charge that comes in higher than what you confirmed.

You need enough available Bitcoin — your verified deposits, minus anything already spent on orders and minus Bitcoin backing bids you're currently winning — to complete a purchase.

• Once a card is paid for it is marked sold and no one else can buy it.
• Checkout collects a shipping name and address. That's the address we ship to, so double-check it before you confirm.

6. Holy Grail offers

Holy Grail cards are the rarest cards on the site. You can send us an offer of $500,000 or more. An offer is a request, not a sale: nothing is charged unless and until we accept it.

Prices shown for Holy Grail cards — from $3,000,000 up — are our asking prices. You can offer below them; we'll tell you if we can't do it.

• You can also buy a Holy Grail card outright at its listed price with Buy now. It's paid from your Bitcoin balance at the live rate, like any buy-now card.
• You can see the status of your own offers in the Holy Grails section.
• An accepted offer is paid from your Bitcoin balance, and the card follows the same 30-day return rule.

7. Withdrawing Bitcoin

You can withdraw your available balance to your own Bitcoin address at any time. The smallest withdrawal is 0.0001 BTC.

Slabmatic does not hold a wallet. Withdrawal requests are paid out by hand from our own wallet, and the payout transaction ID is recorded against your request.

• Bitcoin backing a bid you are currently winning can't be withdrawn until you're outbid.
• A request shows as Pending, then Sent with a link to the payment, or Rejected with the Bitcoin returned to your balance.
• Bitcoin network fees are taken from the payout. Send to an address you control — Bitcoin sent to a wrong or lost address cannot be recovered.

8. Shipping and order tracking

Every card ships with tracking. You can follow it in the Track order section: Paid, then Shipped with a carrier and tracking number, then Delivered.

The delivery date shown in Track order is the date your 30-day return window starts.

9. The cards we list

Cards are listed with their set, year, grading company and grade as printed on the slab. Every slab carries a certificate number you can check on the grader's own website.

We are not the grading company. The grade on the slab is the grader's opinion, not a guarantee from us — which is why every card comes with a 30-day return window.

10. Returns and refunds

Every card is returnable for 30 days from delivery. The full rules — what qualifies, how to start a return and when your Bitcoin is back in hand — are in the Refund Policy.

11. Things you must not do

We will reverse the transaction, keep the card and block the account if anyone:

• Submits a transaction ID that isn't theirs, or the same transaction ID more than once.
• Claims a deposit that was never actually sent, or tries to make a payment appear confirmed when it isn't.
• Uses the site to launder money, or for anything illegal where they live.
• Tries to break, scrape or interfere with the site, the chat helper or another buyer's account.

12. The chat helper

The chat in the bottom-right corner is run by Ash, Slabmatic's AI assistant. Anyone can chat with Ash without an account. Ash answers questions about graded Pokémon cards and about our own rules, and is always labelled as an AI assistant. Talking to a person needs an account.

Ash's answers are general information, not a promise about what a card is worth. When you tap Talk to a person, your messages reach the Slabmatic team and replies come from us, labelled Slabmatic team.

13. Changes to these terms

Listings, prices and auction times change as cards sell. We may update these terms too — the updated date at the top of this page is when they last changed, and the version live on the site is the one that applies to you.
