LAST UPDATED 2026-10-08 · PART OF THE TERMS OF USE

Using Playset can lose you everything you put into it. These are the specific ways, and every power anyone holds over what you own here.

What Playset can do

  • Price trades. A signing service we run quotes every buy and sell-back on a published straight line and signs its half of the transaction. It could quote badly, or stop quoting. It cannot change a quote after you sign it: the quote is the transaction, and any change breaks its signature.
  • Hold unsold units. The signing service holds units that are for sale, never more than a set cap per pool, and the SOL that pays for sell-backs. If its key were stolen, the thief could sell or use those capped units — which can take slabs out of a pool — and spend that SOL. The rest of the unsold units sit in a separate operator wallet that no server holds.
  • Make units. The operator's wallet mints 100 units each time a slab is wrapped into a pool. Anyone can check on chain that a pool's supply is 100 × the slabs ever wrapped; in principle the operator could mint more. A pool can be closed — its mint authority revoked — after which its supply can never change. We will say on each pool page whether it is closed.
  • Change wrappers' metadata and add plugins. The operator holds the update authority of each pool's collection. That lets it change a wrapper's name and picture, and add authority-managed plugins — including one that could block wrappers from moving or burning. We commit not to; any such change is public on chain the moment it is made.
  • Decide on a consignment. Playset reviews each request and can approve, decline, or let it expire. Approval only makes an empty wrapper that belongs to you; the card leaves your wallet only when you move it.
  • Stop selling, or stop buying back. Sell-backs depend on the signing service having SOL; when it runs low it refuses them rather than over-promise.

What Playset cannot do

  • Take a slab or a card out of a wrapper you own. Only the wrapper's owner can move what is inside it.
  • Stop you taking the card out. That transaction is yours alone; no Playset signature is part of it.
  • Move units or wrappers that are in your wallet.

Price and liquidity

The line's price depends on how many units have been sold, not on what a slab is worth elsewhere; the two can diverge. Selling back depends on the signing service having SOL to pay, and on the service running. Taking a whole slab needs 100 units: if fewer than 100 are left unsold, the rest are in other buyers' hands, and you can only get them from those buyers.

Consigning a slab

Consigning starts with a signed request that moves nothing. If Playset approves, you move the card into the pool yourself. From that moment the slab belongs to the pool: anyone holding 100 units can take it out, and you are paid only when that happens — if no one does, you are never paid. The payment is in SOL and is set by how many slabs left the pool before yours, not by what the card is worth anywhere else; SOL's own price moves. A payment depends on the signing service running and holding the SOL; it refuses a payment rather than leave sell-backs unpaid, and pays when it can. The units are minted after Playset confirms your slab is in the pool; a slab taken out before then has its payment held until it is listed. An unsold slab is returned by hand, on request, only while the pool doesn't need it to back units buyers hold.

The cards and their custodian

The physical slabs are held by a third-party vault (Collector Crypt) and represented by its tokens, which sit inside the wrappers. Collector Crypt's tokens carry permanent freeze and transfer delegates: Collector Crypt can freeze or move any of them at any time, including one inside a wrapper. Grades, authenticity and condition are the grader's and the custodian's representations, not ours. Redeeming a physical slab is subject to Collector Crypt's own terms, fees and shipping.

Code

Playset has no on-chain program of its own; wrappers, the escrow and the token run on Metaplex Core, MPL-Hybrid and the SPL Token program, which we do not control and which can have bugs of their own. Our signing service and this site are software and can have bugs; neither has been independently audited.

Regulation and tax

The legal treatment of tokenised collectibles and fractional claims on them is unsettled and differs by jurisdiction. A regulator may take a view that restricts or ends Playset where you are. Trades may be taxable events. Take your own advice.

Beta

Playset is live on Solana mainnet as a beta: pools are small, the signing service and the Site have not been independently audited, and the fees and limits may change for future quotes. Put in only what you are prepared to lose. Devnet test pools (reachable with ?net=devnet) hold test cards with no value and may be reset at any time.

No advice

Nothing on this Site is investment, financial, legal or tax advice, and nothing here is a solicitation to buy or sell anything. A unit is 1/100 of a slab held in a pool — not a promise of profit.

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.
