GUIDE · THE MANUAL

Seven pages.

The same seven pages the manual opens, laid flat. Every number a pool uses — its fees, the next unit's price — is on its own page, read live.

01

One card, one grade, many slabs.

A pool holds copies of exactly one card at exactly one grade. Because every slab in it is interchangeable, a share of the pool is a share of any slab in it, and nothing has to be weighed or ranked.

02

Every slab sits inside its own wrapper.

Each slab's token — Collector Crypt's record of the vaulted card — is moved into a wrapper: a Metaplex Core asset with an account of its own. Whoever owns the wrapper owns what is inside it. Every pool page links each wrapper and its card on a block explorer, so you can see the card is in it.

03

Each slab is backed by exactly 100 units.

When a slab is wrapped into a pool, 100 units are made for it. A unit is 1/100 of a slab. The rule the whole system keeps: units held by buyers never exceed 100 × the slabs still in the pool. Every quote checks it before it is signed, and refuses anything that would break it.

04

A straight line sets the price.

Each unit costs a little more than the one before: the line runs through every unit ever sold, and across one slab's 100 units the price doubles. A slab leaving the pool doesn't move it. Selling back pays the line's value at that point. Buying and selling back pay 2% to Playset, shown as its own line before your wallet opens. The quote is the transaction: what the page shows is what your wallet signs, or nothing happens.

05

Hold 100 units and take a slab whole.

100 units swap for a wrapper — any slab in the pool, because they are all the same card at the same grade. Or buy a whole slab in one step: the page buys the 100 units and swaps them in the same transaction. The 100 units retire and are never sold again, so the rule still holds. Taking a slab costs 0.01 SOL to Playset and about 0.005 SOL to Metaplex.

06

Hand Playset a slab; get paid when it leaves.

Own a Collector Crypt slab of a pool's exact card and grade? Consign it from the pool's page. You sign a request — a message; nothing moves — and Playset checks the card, usually within a day. If it approves, you move the card into the pool yourself with one transaction, and once Playset confirms it, its units go on sale. When a buyer takes it out whole, you're paid in SOL: the line's value of the 100 units it retires — 1.5 × the pool's starting slab value for the first slab out, 2.5 × for the second, and so on. No Playset fee. You need an account with a confirmed email, so Playset can tell you what happened.

07

Own a slab, take the card out — free.

One transaction moves the card into your own wallet and burns the empty wrapper, its small deposit back to you. Playset signs nothing in it, so Playset can't hold it up. From there the card is yours: keep it, list it, or redeem the physical slab with Collector Crypt on their terms.

Terms used

Slab
a graded card in its case, vaulted by Collector Crypt and represented by its token on Solana
Wrapper
a Metaplex Core asset whose own account holds one slab's token; owning the wrapper is owning the slab
Unit
1/100 of a slab in a pool; an SPL token, made 100 at a time when a slab is wrapped
The line
the pool's price: each unit costs a little more than the last one sold; a slab leaving doesn't move it
Signer
the service that prices a quote and signs its half; it holds a capped amount of unsold units and the sell-back SOL
Take whole
swap 100 units for a wrapper through the escrow; the units retire
Card out
the wrapper's owner moves its card to their own wallet; the empty wrapper burns
Closed pool
a pool whose unit mint has been revoked; its supply can never change

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.
