Prepaid and unbounded streams: Some streams like ESOPs would need to be prepaid because employees would need assurance that some set of tokens are locked up in an escrow that will be given to them on the vesting schedule. Other streams like payroll, subscriptions will be unbounded - senders can top up the escrow to keep them running. Both these use cases are supported. Read more about these here.

Support for cliffs: Vesting of RSUs/ESOPs/Tokens involving cliffs is supported.

Cancellable streams: Streams are cancellable. Various different options are available to configure who is allowed to cancel and when.

Pausable streams: Streams can be paused and resumed. This is useful for payroll software which require employees to check in and check out. Options are available to configure who can pause and when.

Unbounded streams solvency detection: Unbounded streams may become insolvent if not topped up timely. There needs to be a way to identify them as quickly as possible and penalize the sender of that stream somehow. Read more about insolvency here.

A Solana on-chain program that maintains the state of all the streams on-chain. Other Solana on-chain programs can interact with it directly using Cross-Program Invocation (CPI for short).

An off-chain software that monitors the on-chain program and cancels streams when they become insolvent. Anyone can run this software and earn rewards for finding insolvent streams and penalizing bad actors in the ecosystem.

A typescript SDK to interact with on-chain Superstream program. Developers would use this typically when they want to create a typescript app and integrate streams into that. It's compatible with browsers and native environments (like React Native).
