Every slot sealed on the XRP Ledger before the first pull. Not even we can move them.
The deck
Every slot filled and sealed before the first pull. They open in the order payments land, and nobody picks.

Grails and majors
Every grail carries a bounty. Pull one, then swap that Monx with us for a custom Monx 1/1, made for you.
Every prize
Provably fair
Every slot was sealed before the first pull. You don’t have to trust us: your browser checks each one.
- Before launchSealed
Each slot got its contents and a random salt. Its leaf is the SHA-256 of the salt, the slot number and the contents. Every leaf was published.
- On the ledgerAnchored
One hash of every leaf and the prize list, the anchor, was written to the XRP Ledger. Change a single slot and it breaks.
- Every pullChecked
Your pull comes with its salt. Your browser redoes the maths, then reads the anchor straight off the ledger.
Check any pull
Paste a payment hash, or tap a pull in the deck or the list.
- Rebuild the slot’s leaf from its salt and contents.
- Compare it with the leaf published at launch.
- Hash every leaf and the prize list: it must equal the anchor.
- Read the anchor off the XRP Ledger: it must be there, from before this pull.
Questions
- What can I win?
- Each slot holds an NFT or a blank. The prizes are Monx and NFTs from other XRPL collections, like Tessera, Pixel Ape Rowboat Club and xShrooms. Every grail is a Monx with a bounty on it: swap it with us for a custom Monx 1/1, made for you. The chances under “What’s inside” are live: prizes left divided by slots left.
- How do I claim a grail’s bounty?
- Accept your Monx like any other prize, then message us on X. We make your custom 1/1 and swap it for that Monx.
- How do I get my prize?
- The machine makes a sell offer for 0 XRP that only the address that paid can accept. Open that wallet and accept it. Only the network fee applies.
- Can I pay from an exchange?
- No. The prize goes to the address that pays, so a payment from an exchange sends it to the exchange. Use a wallet you control, like Xaman.
- What if I forget the tag?
- Without the destination tag the machine can’t match your payment to your spin, so the ledger turns the payment away and your XRP stays with you. Xaman fills the tag in when you scan its QR code. In Joey and most other wallets, copy the tag and paste it in.
- Who picks my slot?
- Nobody. Slots open in the order payments land on the ledger. Their contents were shuffled across the whole deck and sealed before the first pull, so no stretch of it is luckier than another.
- Can I check someone else’s pull?
- Yes. Tap any opened slot in the deck or any line in “Latest pulls”, or paste a payment hash under “Check any pull”.
