# Smart Contracts

The HBARX Smart Contracts play a crucial role in the Stader-HBARX protocol, serving as the fundamental building blocks of the entire network. These contracts form the foundation upon which various components of the system are constructed, such as the staking mechanism and the user interfaces for end user applications.

Here is the list of the HBARX Smart Contracts. This list serves as a reference point for HBAR staker, validators, developers, researchers, and enthusiasts who are interested in exploring the inner workings of the Stader-HBARX protocol and understanding how the different components interact with each other.
