Finch docs

Finch is a marketplace for real, graded trading cards — Pokémon, Magic, Yu-Gi-Oh!, and sports. Every card is a genuine, professionally graded slab that's physically vaulted and represented on-chain. You buy, collect, sell, and open packs, all settled from a single balance. The blockchain plumbing (bridging, custody, settlement) is handled for you.

You hold one balance — ETH on Robinhood Chain — and pay with it. When you buy, Finch bridges exactly what's needed into your Collection Wallet, purchases the card, and delivers it there. You approve a single signature; there are no bridges, gas tokens, or Solana wallets to manage. Prices are live and the total you approve already includes all costs.

See How to buy for the step-by-step.

Connecting an Ethereum wallet is your account — there's no separate sign-up. Finch provisions a Collection Wallet for you where your cards are delivered and held on-chain. On self-custody deployments you can export that wallet's private key at any time from Wallets → Export private key, after proving ownership by signing a one-time message. Anyone with that key controls the wallet, so keep it safe — Finch can never recover a lost key.

Packs are sealed, provably-fair drops (on-chain VRF). Buy and open a pack in one flow; the card you pull is real, graded, vaulted, and delivered straight to your Collection. The price shown is the price you pay.

List any card you hold for sale from your Collection or the Sell page. You keep custody until it sells; when it does, the proceeds land in your Collection Wallet in USDC, which you can withdraw. We show a live market estimate from real comparables so you can price it well.

Finch takes a small fee on trades, baked into the price you approve — you never see a surprise charge at checkout and you're never charged twice. Network and marketplace costs are handled within that price.

$FINCH is the Finch token. Its contract address is shown in the header (click to copy) — always verify it there before interacting with any token claiming to be $FINCH. Nothing here is financial advice or a promise of return; see the Terms.
