# Read Tab

The Read Contract Tab enables users to access and query the contract's read-only functions to fetch data directly from the blockchain. These functions are used to retrieve information without making any changes to the blockchain, meaning no tokens or gas fees are required.

**Wallet Connection**

Allows users to securely connect their wallet to the interface. Although read-only functions don’t require gas or tokens, wallet integration ensures secure and authenticated interactions with the contract.

**Contract Information**

* **Public Functions:** Displays a list of all publicly accessible read functions within the contract. These functions provide data such as balances, token details, or contract status.
* **Expandable Functions:** Each function is listed with its name *(e.g., \_verifyTransfer)*. Users can expand any function to view input fields or directly execute a query to retrieve outputs.
* **Inputs and Outputs:** Some functions may require input parameters *(e.g., wallet addresses)* to fetch specific data. The output provides the requested information in real time.
