# Write Tab

The Write Contract Tab allows users to perform state-changing actions on a smart contract, such as transferring tokens, updating settings, or triggering specific operations. These interactions modify the blockchain's state and require wallet authorization.

**Wallet Connection**

Users must connect their wallet to execute write functions. This ensures secure interactions, allows authentication and facilitates the payment of gas fees required for the transaction.

**Contract Information**

* **Callable Functions:** The tab lists all available write functions within the smart contract *(e.g., batchTransferETH)*. These methods enable users to make changes to the blockchain's data.
* **Expandable Functions:** Clicking on a function name expands it to reveal input fields and options for user interaction.
* **Input Fields:** Each function displays the required inputs *(e.g., wallet addresses, token amounts)* that users must provide to execute the operation.

**Executing Transactions**

* **Execute Button:** Once all input fields are completed, users can click the Execute button to initiate the transaction. This will prompt the connected wallet for confirmation.
* **Gas Fees:** Executing write functions incurs gas fees. The estimated fee is displayed in the wallet confirmation screen, ensuring users are aware of the cost before approving the transaction.
