In this tutorial, we covered how to use Solana's Program Library to build a simple application with pre-built functions. By leveraging SPL, you can significantly reduce development time and complexity. The SPL ecosystem is continuously growing, offering more tools and libraries to help you build powerful decentralized applications on Solana.
