SlabStakeOwn a share of the cards you collect.
Deposit crypto and receive a cash balance, then pledge toward PSA-graded cards alongside other members. Once a card is funded, SlabStake buys the physical slab and has PSA vault it, and the pledges become its shares, one share for each dollar it cost. A few dollars is enough, and so is full ownership.
No marketing email. Deposits work from any wallet or exchange, and no browser extension is required. An address is all we need for now.

What you can do today
Crypto deposits and card funding are built, and so is the order book where shares trade once a card is vaulted. All of it is in final testing.
Fund with any crypto
Send BTC, ETH, SOL or a stablecoin to your own deposit address. Whatever arrives is turned into a dollar balance automatically, with no wallet to connect and no browser extension to install.
Own a fractional share
Pledge toward a card's funding target, from the minimum order up to what remains. Once the card is bought, each dollar of its real cost becomes one share, and every pledge is settled in those shares, with any remainder returned to your balance.
Real cards, held by PSA
Cards are sourced from eBay’s PSA Store and sent directly to the PSA Vault. A public custody log records the purchase, the shipment and the vaulting, each against its own reference.
Trade shares in the order book
Once a card is vaulted, its shares trade in an order book at a price per share. Buy or sell at once, or place an order and wait for a match. A trade settles against cash balances the moment it fills.
See exactly who owns what
Every card shows a live cap table once its shares are issued, updated with each trade. While a card funds, a counter shows the percentage of its target already pledged.
One person, one account
A single identity check at signup keeps duplicate accounts out of the market. A card is then sold when holders of more than half its shares support the sale, and each holder is paid to the nearest cent.
How it works
Deposit crypto
Send any major coin to your own deposit address, from a wallet or an exchange. It arrives as dollars.
Back a card
Choose a PSA-graded card and pledge toward its funding target. Once the pledges reach it, SlabStake buys the physical card and issues its shares, one for each dollar it cost. PSA then vaults it.
Trade or exit
Follow the market value and trade shares in the order book once the card is vaulted. Holders may also support a sale of the whole card, and each is paid to the nearest cent.
