## Swap Auto Mode

Auto Mode is the new advanced routing mode, enabling users to just specify their preferences upfront via a gasless signature and BIM automatically selects the best route and executes it onchain. BIM Auto is designed to maximise efficiency, security and UX. BIM Auto plugs into a vast marketplace of fillers, solvers and provers to provide best chain-abstracted swap execution to end users.
