Confidential Exchange — Canton Network

The first NFT house where the price is a secret until you choose to reveal it.

Every public marketplace shows every bid, every wallet, every price — forever. Privé borrows the auction house's oldest trick: sealed bids and private treaty sales, made possible on-chain by Canton's sub-transaction privacy, where only the parties to a trade ever see its terms.

What we borrowed from the real art world

OpenSea and every EVM marketplace inherited one flaw from public blockchains: total transparency. Auction houses never worked that way — and now, neither do we.
Core Adoption

Sealed & Absentee Bidding

Christie's and Sotheby's have run sealed and absentee bid auctions for centuries — bidders never see competing offers. Public chains made this impossible: every bid is a broadcast transaction. Canton's privacy model lets us record a bid as a contract visible only to the auction house and the bidder, exactly like a paddle raised in a private room.

Private Treaty Sale

Galleries sell major works quietly, off the public record, at a negotiated price. We replicate this: fixed-price listings can be negotiated privately between buyer and seller with terms invisible to the rest of the network.

Confidential Cap Table

Company shareholder registries are never public. Ownership history here works the same way — full provenance is provable to the parties involved, redacted to everyone else.

Escrow-Style Settlement

Real estate closings use a neutral escrow to guarantee atomic exchange of title for funds. Our settlement layer guarantees the same atomicity — asset and payment move together, or not at all — without a visible public mempool.

Invite-Only Viewing Rooms

Just as a dealer only shows certain collectors certain pieces, Private Galleries here are visible only to allow-listed parties — a first for on-chain collectibles.

The Exchange

Public listings — visible to everyone, priced openly, exactly like a gallery's front window.

Live Sealed-Bid Auction

Bids are hidden from every other bidder until the auction closes — only your own bid is ever shown to you.

Closing in

05:00
Your bid is committed as a private contract between you and the auction house. Other bidders — and the public network — cannot see it, your identity, or whether you've bid at all.

Provenance, Selectively Disclosed

Full ownership history is provable — but only to the parties entitled to see it. Switch views below to see the same asset from two perspectives.

Three Ways to Sell

Public

Fixed Price Listing

Open, visible, instant — same as any marketplace today. Good for building a public floor price.

Semi-Private

Private Treaty Sale

List a floor price publicly, negotiate the real price privately with a serious buyer — terms settle without ever becoming public.

Fully Sealed

Sealed-Bid Auction

Best for competitive, high-value lots — every bidder commits blind, only the winning bid and price are ever revealed.

List an Item

Choose how visible you want the sale to be — from fully public to fully sealed.

Frequently Asked Questions

On EVM marketplaces, every bid, sale price, and wallet history is public forever. On Privé, only the parties to a given trade — buyer, seller, and the exchange contract — ever see its terms, because Canton only replicates transaction data to parties actually involved in it.
The same way a sealed-bid art auction has always worked: the auction house's settlement logic is enforced by the smart contract itself, so the winning bid is determined deterministically and the losing bids remain confidential — verifiable in aggregate without exposing individuals.
Yes — a Private Gallery is only synchronized to allow-listed parties. Outside that list, the collection simply doesn't appear in your ledger view, the same way a dealer's back room isn't on the shop floor.
No — full transaction history remains cryptographically provable to whoever is entitled to see it (e.g. a new owner, an auditor). It's selectively disclosed, not hidden from everyone; that distinction is the whole point.
Royalty enforcement is written into the same atomic settlement as the transfer itself, so the creator's cut settles automatically regardless of whether the price was ever made public.
