# Solana SDK Use the Solana SDK Crate to write client side applications in Rust. If writing on-chain programs, use the [Solana Program Crate](https://crates.io/crates/solana-program) instead. More information about Solana is available in the [Solana documentation](https://solana.com/docs). The [Solana Program Library](https://github.com/solana-labs/solana-program-library) provides examples of how to use this crate. Still have questions? Ask us on [Stack Exchange](https://sola.na/sse)
