# BatchMessageSender

> Example app of sending multiple messages in one transaction

## Methods

### executeMessage

```solidity
function executeMessage(bytes32 _srcAddress, uint256 _srcChainId, bytes _message, address _executor) external nonpayable
```

Executes a message called by MessageBus (MessageBusReceiver)

*Must be called by MessageBug & sent from src chain by a trusted srcApp*

#### Parameters

| Name         | Type    | Description                                                                    |
| ------------ | ------- | ------------------------------------------------------------------------------ |
| \_srcAddress | bytes32 | The bytes32 address of the source app contract                                 |
| \_srcChainId | uint256 | The source chain ID where the transfer is originated from                      |
| \_message    | bytes   | Arbitrary message bytes originated from and encoded by the source app contract |
| \_executor   | address | Address who called the MessageBus execution function                           |

| \_chainId | uint256 | undefined   |

#### Returns

| Name          | Type    | Description |

| trustedRemote | bytes32 | undefined   |

### messageBus

```solidity
function messageBus() external view returns (address)
```

#### Returns

| Name | Type    | Description |
| ---- | ------- | ----------- |
| \_0  | address | undefined   |

### renounceOwnership

```solidity

### setTrustedRemote

```solidity
function setTrustedRemote(uint256 _srcChainId, bytes32 _srcAddress) external nonpayable
```

#### Parameters
