## Usage

### LayerZero V1

```solidity
interface ILayerZeroEndpoint {
    function send(
        uint16 _dstChainId,
        bytes calldata _destination,
        bytes calldata _payload,
        address payable _refundAddress,
        address _zroPaymentAddress,
        bytes calldata _adapterParams
    ) external payable;
}

// Example
ILayerZeroEndpoint endpoint = ILayerZeroEndpoint(0xb6319cC6c8c27A8F5dAF0dD3DF91EA35C4720dd7);
```

### LayerZero V2

```solidity
interface ILayerZeroEndpointV2 {
    function send(
        MessagingParams calldata _params,
        address _refundAddress
    ) external payable returns (MessagingReceipt memory);
}

// Example
ILayerZeroEndpointV2 endpoint = ILayerZeroEndpointV2(0x6F475642a6e85809B1c36Fa62763669b1b48DD5B);
```
