SUMMON · $PLAYSET

Summon the next slab.

Burn $PLAYSET toward the card you want pooled next, then pledge how many units you'll take. Once pledges cover a whole slab, Playset buys it, vaults it and opens the pool. For the first 48 hours only summoners can buy, each at their place in line, and the line goes by burn.

  1. Burn. Your wallet burns $PLAYSET with a note naming the card. It's gone for good, and it buys a place in line, nothing else.
  2. Pledge. Sign a message saying how many units you'll take, up to a quarter of a slab. A pledge moves nothing and costs nothing.
  3. Last call. When pledges cover the slab, a 24-hour clock starts. Burns still count and can still change the order. Then the line locks.
  4. Open. Playset sources the slab and opens the pool. Your place is priced where it sits on the pool's line, so the front of the line pays the least.

If a card isn't covered in 14 days, it lapses. Nothing was taken, so there's nothing to give back; the burns stay burned.

WHAT RUNS WHERE.

Playset has no program of its own. Slabs, wrappers and the escrow run on Metaplex's audited, deployed programs; prices come from a small signing service whose every trade is a public Solana transaction. Your wallet signs only what the page showed you first.

Wrappers
Metaplex Core assets, one collection per pool. Each wrapper has its own wallet (Core's asset signer) that holds the slab's token — a Collector Crypt Core asset or pNFT.
Escrow
MPL-Hybrid. 100 units take a wrapper out of the pool; an empty wrapper buys nothing back.
Signer
— prices each trade on the line and signs its half. It holds unsold units — never more than a capped amount — and the SOL that pays for sell-backs. Nothing else.
Line
p(s) = p₀ · (1 + s / k), where s counts every unit sold, net of sell-backs — including the units a slab retires when it leaves, so a slab leaving moves nothing. With k = 100 the price doubles across one slab's units. Selling back pays the line's value at that point.
Depositors
the depositor of the j-th slab to leave is paid the line's value from (j − 1)·100 to j·100, by the signer, with a memo playset release <pool> j=<j>. The signer refuses any payout or sell-back that would leave it unable to buy back every unit buyers hold.
Fees
2% on buys and on sell-backs, a separate line in the transaction; 0.01 SOL to take a whole slab, plus about 0.005 SOL to Metaplex; 2.5% royalty if a slab is resold on a marketplace. Taking the card out, consigning a slab and depositor payments: free.
The rule
units held by buyers never exceed 100 × the slabs in the pool. The signer checks it on every quote and refuses anything that would break it.
The card out
the wrapper's owner moves the card to their own wallet with Core's execute and burns the empty wrapper in the same transaction. No Playset signature is involved, so none can be withheld.
