SlabStake
Fractional funding

A penny buys a share. Every time.

Every card on SlabStake is split into 1¢ shares. The funding target you see is the card’s full cost — price, tax, shipping and the platform fee — so there are no add-ons at checkout, ever.

The lifecycle

From eBay listing to penny-exact exit

Five stages, all visible on the card’s page as they happen. Nothing is simulated — every shelf, cap table and log entry is live data.

01
Sourced

Cards come from eBay’s PSA Store, and every cert is verified against PSA before listing.

02
Funding opens

Members back the card at 1¢ per share. A live cap table and % funded sit on every card page.

03
Fully funded

We buy the physical card and ship it to the PSA Vault, logging every custody step publicly.

04
Trading opens

Once vaulted, shares trade on the secondary market — instant, wallet-settled lots at your price.

05
The exit

When holders of over 50% of shares support a sale, the card sells and proceeds split pro-rata — to the exact cent.

The guarantee

If the card can’t be bought, everyone gets refunded.

If a listing ends or its price rises before funding completes, the card is cancelled and every holder is refunded in full — automatically, with no support ticket. If the price drops, you keep your stake in a cheaper card and any funding it no longer needs comes straight back to your balance. Funding either ends with a vaulted card or with your money back.

How the money is held

Dollars in, ledger-backed, to the cent.

Crypto is how money moves in and out — balances are always US dollars. Every amount is integer cents on an append-only ledger: your balance is the sum of its entries, never a number anyone can edit.
