Components

Liquidity sources: propAMMs and conventional DEX pools that quote and fill orders. Each propAMM is operated independently and prices from its own logic and inventory. Routing engine: The layer that quotes every candidate source onchain for a given order, ranks the results by output net of gas, and selects the route. Settlement contract: The onchain contract that executes the selected route atomically and verifies that the output meets the order’s minimum. Swap API: The integration surface that returns firm quotes and ready-to-send transactions to wallets, frontends, and other routers.

​
Order flow

  1. An order is submitted through the Swap API.
  2. The routing engine quotes all supported sources against live onchain state.
  3. Quotes are ranked by output net of network costs and a route is selected.
  4. The settlement contract executes the route onchain in a single transaction and enforces the minimum output.

Where Rialto sits

Rialto operates between the application a user trades through and the underlying liquidity. Applications integrate the Swap API for execution, including rialto.xyz; liquidity sources integrate as quoting and settlement venues. Routing and settlement remain onchain across both sides.
