Overview

Ruby interface for the Solana System Program (11111111111111111111111111111111).

The System Program is responsible for creating accounts, transferring SOL, and other low-level operations. Instruction data uses little-endian encoding: a u32 discriminator identifying the instruction variant, followed by any instruction-specific fields.
