The problem Solerris solves

Currently there involves no system that solves the streaming of payments on solana where a user can create a contract to send tokens within a finite amount of time and stop/pause the transaction within this limit.
Any wallet can create or recieve these tokens.

Challenges we ran into

Rust is a very low level and nearer to C and thus has a learning curve that required us to think in new patterns quickly. Frameworks around Solana have documentation that is great but still requires more detail towards using and building on them.
