smart_relay=true
) for global coverage of all chains, bridges, and routesThere are many routes that will return a RouteNotFound error if smart_relay=false
because there are not public relayers that support them. This includes all routes to and from Solana, as well as CCTP routes to and from Polygon, Base, and several other L2s.As a result, if you want your users to be able to transfer their tokens over all routes, we recommend using Smart Relay.
