Private offers

Make funded offers on any tracked collectible, or list your own at a fixed price.

Private Offers are our built-in OTC desk, and it runs both ways: make a private, funded offer on any tracked collectible straight from its detail page, or list one of your own at a fixed price for anyone to buy. It is peer-to-peer with no oracles, so you deal directly with the owner, and it works on both EVM chains (Ethereum, Base, Polygon and more) and Solana.

Make an offer modal

To make an offer, set your amount in USDC and an expiry, then sign. Nothing is held in custody: on EVM you sign a Seaport bid order and on Solana you approve the USDC, so the owner always sees a real, funded offer they can settle at any time. Buying below market is the whole point of OTC, but there is a floor: an offer must be at least 70% of the card's fair market value. You can even pay with USDC from a different chain and it bridges over automatically before the offer goes live.

The owner finds every offer in their inbox at /o, split into Received and Sent, and can accept, reject, or ignore each one. When they accept, the trade settles on-chain atomically: the collectible moves to the buyer and the USDC goes to the seller, minus a small 1% fee charged only on the cash leg.

The desk also works the other way round. On any collectible you own you can hit List for sale, name a price in USDC and an expiry, and anyone can buy it outright at that price without negotiating. Prices go up to 30% above fair market value, so a listing is always something a buyer could realistically take. Listed cards show a USDC price button wherever they appear, and the switch beside the search bar filters the whole site down to what is for sale.

Listing keeps custody exactly where offers do: nowhere. Your card never leaves your wallet, you only approve the sale so it can be delivered the instant someone buys, and you can delist whenever you like. Buying a listing needs only a wallet, no account, and the buyer can pay with USDC from another chain and let it bridge over first; every sale is checked on chain before the listing is marked sold. The same flat 1% applies, paid by the seller, and once it sells you can see who bought it.
