proxiableUUID()
view
dev: Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade. IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the `notDelegated` modifier.

|---|---|---|
| — | bytes32 |

init2()
nonpayable
This function shall be called by previously deployed contracts.
pause()
nonpayable
Pauses the contract.
processMessage(_message: tuple, _proof: bytes)
nonpayable
dev: To ensure successful execution, we recommend this transaction's gas limit not to be smaller than: `(message.gasLimit - GAS_RESERVE) * 64 / 63 + GAS_RESERVE`, Or we can use a simplified rule: `tx.gaslimit = message.gaslimit * 102%`.
