Each protocol is a set of Solana smart contracts plus off chain indexers and APIs. They are designed to be plug and play for any project on Solana. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
