Kunal Arora	c9085afd96	fix: add fix for checking for correct messageId in `OPL2ToL1Ism` and `ArbL2ToL1Ism` via external call (#4437) ... ### Description - In agreement with Chainlight team's recommendation, added a second isVerified() check after portal call to make sure an arbitrary call which passes the check for metadata length and messageId cannot be verified without calling is verifyMessageId(messageId) in `OPL2ToL1Ism` and `ArbL2ToL1` ### Drive-by changes None ### Related issues - fixes https://github.com/chainlight-io/2024-08-hyperlane/issues/2 ### Backward compatibility No, but the contracts aren't deployed anywhere ### Testing Unit testing	1 month ago
Kunal Arora	6f377f1743	feat: implement `OPL2ToL1Ism` contracts (#4319) ... ### Description Implementing the `OPL2ToL1Hook` and OPL2ToL1Ism` contracts for using the Optimism native bridge for sending messages from the L2 to L1. - Optimism needs double call encoding for the direct portal call because the portal itself calls the l1Messenger which then directs it to the ism. ### Drive-by changes None ### Related issues - fixes https://github.com/hyperlane-xyz/issues/issues/1346 ### Backward compatibility Yes ### Testing Unit testing with mocks for OP contracts	4 months ago
