What is Rialto?

Rialto is an onchain spot exchange to trade crypto, equities, ETFs, and commodities. Your orders are routed to the best available execution across the sources Rialto supports.

Rialto’s defining liquidity source are propAMMs: onchain market makers that quote a price from their own pricing logic and inventory, rather than from a passive constant-product pool. Rialto quotes every candidate source onchain at request time, ranks routes by output net of gas, and settles the winning route. propAMMs compete alongside conventional DEX pools on every quote, so you get the best price without choosing a venue yourself.
