Solana Program Library (SPL)
The Solana Program Library (SPL) is a collection of on-chain programs targeting the Sealevel parallel runtime. These programs are tested against Solana's implementation of Sealevel, solana-runtime, and deployed to its mainnet.
Note
The Python SPL library is separate from the main Python Solana library,
so you import it with import spl
instead of import solana
.
You don't install it separately though: it gets installed
when you run pip install solana
.
