CashStream is a React web application to facilitate real-time crypto payment. It allows the user to open a continuous "stream" from one wallet address to another, where crypto assets will be transferred in real-time.
Our application is built for Goerli Testnet. It works for two Ethereum-based tokens, ETH and fDAI (stablecoin).
It includes a mock subscription service to demo "pay as you go" proof of concept. The service will be available only if the user opens a stream to the designated recipient address (0x45c01ceb87dbe6807ebecb9161408fc5c6acb5d1). (github repo) We also have a proof of concept for livestreaming content, like YouTube Live, Twitch, OBS, etc., which a viewer gains access to by initiating a payment stream. Video Demo and Github.
CashStream uses the Superfluid Protocol. Superfluid is a De-Fi company working to enable money streaming in subscriptions, investment, etc.
