A comprehensive guide to understanding and using Solana's standard program libraries for tokens, NFTs, governance, and more in your applications.

Overview

Solana Program Libraries (SPL) provide a set of on-chain programs that implement common standards and functionalities within the Solana ecosystem. This guide explores the most important SPL programs and how to use them in your applications.

Key SPL programs covered:
