Cards tokenized by Collector Crypt

Real graded cards in a vault, each one a pNFT on Solana. A coin pairs with one card and its fees pay for it.

Cards and prices are live Collector Crypt listings on 8 Oct 2026. The coins and funding figures are examples.

The fees buy the card

On pump.fun, creator fees go to the dev. On Sleev, they go into a fund that buys the paired card. Then the card goes to the holders.

01

Pair a card

Pick a card listed on Collector Crypt. Its listing price becomes the coin's target. The card is a real graded slab in a vault, tokenized as a programmable NFT.

02

Launch the coin

The coin is created on pump.fun with the Sleev vault as its creator. Trading works like any other pump.fun coin. The card and the target are shown on the coin's page from the first trade.

03

Fees buy the card

Every creator fee claim goes into the card fund: 80% to the fund, 10% to the dev, 10% to Sleev. When the fund reaches the listing price, the vault buys the card on Collector Crypt. Nobody has to press anything.

04

Holders win the card

The card is auctioned to holders, with bids placed in the coin itself. The winning bid is burned. The winner holds the pNFT and can redeem the physical card through Collector Crypt. Then the coin pairs its next card.

Why a card

Fees that leave to a wallet are gone. Fees that buy a card stay with the coin, as a slab anyone can see in the vault.

A coin today

  • The dev's wallet receives the creator fees forever.
  • To cash out, the dev sells tokens into the chart.
  • Trading volume builds nothing. Holders own a chart.

A coin on Sleev

  • The creator fees buy the paired card, automatically.
  • The dev keeps 10% of fees and whatever tokens they bought, like anyone else.
  • Trading volume buys cards. Holders win them, and every win burns supply.

Built on pump.fun and Collector Crypt

Nothing changes for traders. The coin is a normal pump.fun coin with a normal bonding curve.

The coin
Lives on pump.fun, then on PumpSwap after migration. Standard creator fee schedule. Sleev adds no trading fee.
The creator
The Sleev vault, a program-owned address, is declared as the creator at launch. Fee collection on pump.fun is permissionless, so anyone can trigger a claim and the vault routes it into the card fund.
The card
A Collector Crypt pNFT. The fund swaps SOL to USDC and buys the listing through the Collector Crypt marketplace. If the card sells to someone else first, the fund moves to the next listing of the same card, or the dev pairs a new one.
What Sleev does not do
It does not stop snipers at block 0, and it cannot override pump.fun's own reassignment of a coin's creator. Sleev is independent of both platforms.
