The Developers chapter presents technical information about Idle protocols (Best Yield and Yield Tranches), as well as details about Idle [fees](https://docs.idle.finance/products/fees) and [security](https://docs.idle.finance/developers/broken-reference).

All the key initiatives concerning the Idle codebase are available on the [Idle Labs GitHub ](https://github.com/idle-labs)and [Idle DAO Github](https://github.com/Idle-Finance).
