# Smart Contracts

The hBTC protocol is organized into several smart contract domains covering governance, user interaction, trading, and accounting. 

Governance contracts manage permissions, configuration, and safety controls; user-facing contracts handle deposits, withdrawals, and the hBTC token; trading contracts interface with external protocols for strategy execution; and accounting contracts manage NAV updates and the reserve fund. 

All assets are held within a dedicated reserve contract, providing a single, auditable asset layer across the system.
