Currently creating a stream to a recipient address on a different chain(you don't have liquidity on) is not possible in Superfluid.
With XStream, you can start a stream to any EVM chain from the chain you have your treasury on.
While the potential is much more, here's a few things XStream enables:
• allows anyone to send a stream to a recipient address on a chain they don't have liquidity on without the need to bridge tokens to that chain and having native tokens to pay gas for initiating the stream
• enables protocols and DAOs to compensate contributors on the contributor's chain of preference without building a separate treasury on each chain
• enables yield protocols can now distribute USDC rewards every second to users' chain of preference agnostic to the chain protocols hold their securities in
• enables creators and merchants in web 3, to create subscription strategies based on a unit of time and accept payment streams from any EVM chain user to their contract on their chain of preference.
