Launched in May 2022, Odos is available on 15 EVM chains and uses a patented algorithm to deliver the best swap rates to retail and institutional traders. Our multi-token swap feature allows users to trade many tokens in a single atomic transaction, and our newly launched intent based order types are leading the way in advancing the Web3 user experience.
