THE CASE

Three moves, then see it for yourself.

THE PROBLEM

Shopping a block leaks the trade.

Ask five desks for a price and five desks now know you’re a seller. The market moves before you clear — and you wear the slippage.

01 / 03

THE INSIGHT

Privacy as a protocol property — not a promise.

Canton enforces sub-transaction privacy. A rival never sees your bid because the ledger never reveals it to them — no auctioneer to trust, no ZK circuit to audit.

02 / 03

THE MECHANISM

Sealed bids in, one winner out, atomic settlement.

Invited counterparties submit sealed bids. The seller clears to the best one and asset-for-cash settles in a single transaction. Losers get escrow back and never learn the price.
