Program Crates
Use solana-program to build on-chain programs.
Pinocchio is a zero-dependency library to create Solana programs in Rust and can
be used as a replacement for solana-program to write on-chain programs.
Pinocchio is still in development and will likely have breaking changes in the near future.
Pinocchio includes program-specific crates for interacting with Solana programs:
