When you place an order, Rialto requests a live price for your exact size from
every supported liquidity source, compares them by how much you receive after
network costs, and routes your order to the best result. This happens on every
order.
There is no venue to select and no routing setting to configure. Rialto selects
the source for you, drawing on its own propAMM, third-party propAMMs, and
conventional DEX pools.
When splitting an order across more than one source produces a better overall
result, Rialto does that automatically. You still see a single trade with one
outcome.
