# Send Batch Transactions

A batch refers to a group of calls inside a single user operation. This can be an approve and send transaction in one call. The executeBatch() method is used.

| Parameter | Type       | Status     | Description                                      |
| :-------: | ---------- | ---------- | ------------------------------------------------ |
|   **to**  | *address*  | *required* | The address where the user want to send Tokens.  |
| **value** | *number*   | *required* | The amount of Tokens the user is sending         |
|  **data** | *Function* |            | Encoded Function Data for Smart Contract Methods |
