# @haven1/wagmi-sdk

### Key Features

#### 1. **Chain Constants for Wagmi**

* Easily integrate the Haven1 blockchain into your project by using predefined chain constants in the Wagmi data type.
* Automatically configure the Haven1 chain in your Wagmi client setup without needing manual configuration.

#### 2. **Pre-Made React Hooks**

* **Connected Hooks**: Ready-to-use React hooks that connect to Haven1 smart contracts via Wagmi, making it easy to fetch user data, developer fees, and other blockchain-related information.
* **Smart Contract Integration**: Directly interact with Haven1 smart contracts, such as querying user information or retrieving developer fees, with minimal code.

#### 3. **Wagmi-Wrapped Hooks**
