Every card here is a physical graded slab in insured custody, tokenized 1:1. It is marked to live sales comps, then haircut. Borrow up to 50% without selling.

A depositor puts a graded card into the vault and borrows against it. The card never leaves your control until you either repay, or the loan is auctioned. Every position is isolated in its own escrow.
Ship a graded card to the custodian in insured storage. It is tokenized as an on-chain receipt (an ERC-721) that you hold. The receipt is redeemable for physical delivery any time it is not locked in a loan.
One card, one position. Never pooled, never lent against another slab, never commingled.
An appraiser pushes the card's value on chain from live sales comps (PriceCharting, PSA auction prices). A haircut discounts it to a conservative mark. Your borrow limit is a fraction of that mark.
Draw up to 50% of the marked value in USDC. Interest accrues per second and is paid to the suppliers funding the pool. Repay any amount at any time; clear the debt and the slab unlocks instantly.
Keep the card, keep the upside. You only sell if you want to.
If the comp drops or the loan crosses the line, anyone can liquidate it. The slab goes to an English auction open to other slab holders, with a 15 minute anti-snipe. Bids are USDC.
Proceeds repay the pool first, the liquidator earns the penalty, and any surplus goes back to you. The winner gets the card.
When a loan is liquidated its slab is auctioned in USDC. Bidding is open to slab holders only. Win the card below market, the pool gets made whole, and the borrower keeps any surplus.
Supply USDC and earn the interest borrowers pay against real, vaulted collateral. Withdraw whenever there is idle liquidity in the pool.
