// Deposit ETH to L2
bridge.depositETH{value: amount}(
    minGasLimit,
    emptyBytes  // No additional data

IL2CrossDomainMessenger messenger = IL2CrossDomainMessenger(0x4200000000000000000000000000000000000007);

// Send message to L1
messenger.sendMessage(
    targetL1Address,
    abi.encodeWithSignature("someFunction(uint256)", value),
    minGasLimit
);
```
