Overview

The Cross-Chain Swap Engine (the “CCSE”) is a non-custodial, bilateral Request-for-Quote (“RFQ”) system that enables eligible users to exchange supported digital assets between Canton Network and Ethereum without depositing assets into a platform-controlled account.

A user submits an RFQ to one or more eligible Liquidity Providers (“LPs”). Each LP evaluates the request independently and may respond with its own quote. Each quote is a separate proposal from an identified LP, and the user independently decides whether to accept, reject, or allow the quote to expire.

The CCSE does not operate an order book or matching engine and does not aggregate, rank, prioritize, or optimize quotes. Assets are not pooled or commingled, and the CCSE does not use a liquidity pool or automated market maker.

If the user accepts a quote, the resulting transaction is bilateral between the user and the identified LP. Interstice may itself act as an LP only when it is expressly identified and disclosed as the direct counterparty.

Cross-chain settlement is implemented through smart-contract mechanisms on Canton and Ethereum. Users and LPs authorize their own transaction steps through their own wallet infrastructure. Interstice does not hold user private keys or sign transactions on a user’s behalf.
