PS10 · AN INDEX OF PSA 10 SLABS

PS10 —

reading…

One unit of every card on the list, valued at what that card actually sells for on Collector Crypt, over a divisor, the way the Dow is built. When the list changes, the divisor resets so the level doesn't jump because a card joined.

PS10 is a list and a number. There is no index token and there won't be one. Buying the index is one transaction that puts a unit of every card on the list straight into your wallet. $PLAYSET is the committee that votes cards on and off the list, and the only way to pay for a basket: its fee is burned.

Both lines start at 1000 on PS10's first day. The market line is a repeat-sales index: each week it compares every PSA 10 that sold to the same card the week before, so a week full of expensive cards doesn't read as a rally.

ON THE LIST

One of each——

Unit, market: the card's 30-day median sale on Collector Crypt (or its last sale, under three), divided by 100. Unit, Playset: the pool's next unit at spot, before the 2% fee.

BUY OR SELL THE INDEX

One transaction: a unit of every card on the list, each at its own pool's price on the line, straight into your wallet, or all of them sold back at once. No index token is involved. The fee is 2% of the basket, paid by burning $PLAYSET from your wallet in the same transaction instead of in SOL.

THE COMMITTEE · $PLAYSET

Burn $PLAYSET to vote a card onto the list, off it, or to keep it. Every Sunday at 00:00 UTC the week's burns decide: a card comes off when burns to drop it reach the minimum and beat burns to keep it, and a Playset pool goes on when burns to add it reach the minimum, most burned first, two a week, never more than ten on the list. Burning pays nobody and wins nothing; every vote is its own public transaction.

    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.
