Cessio is a confidential RFQ desk for large trades on Canton Network.
Ask the market makers you choose for a firm price on the whole amount,
take the best quote, and both legs settle atomically in one Canton transaction.
Losing makers never learn your price or size — and the network never sees the trade.
| Step | What happens |
|---|---|
| 1 · Request | A taker asks a chosen set of makers for a firm price on the full size. Nobody else is asked, and nobody else sees the request. |
| 2 · Quote | Each maker answers with a signed, ready-to-settle proposal that lives on the ledger — not an off-chain promise. |
| 3 · Take | The taker takes the best quote. The losing makers never learn the winning price. |
| 4 · Settle | Both legs move in a single Canton transaction, or nothing moves. No escrow, no bridge, no counterparty risk. |
That privacy is Canton's sub-transaction confidentiality, not a policy we promise to keep. Party keys are generated in your browser and never leave it — Cessio never holds your assets. Works with cBTC, cETH, Canton Coin and any other Canton token-standard asset.
