# Roles The main pool [operations](#main-operations) imply the following roles that enable the protocol to function and benefit from it: * **LPs** - Provide liquidity for solvers. Get yield from collected protocol fee. * **Solvers** - Make use of liquidity for solving. May also benefit from rebalance operations. * **PAs** - Receive increase in protocol usage. Attract new users and income. * **DAO** - Extends protocol for more solving possibilities. Ensures security for LPs and solvers. --- # 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.
