This ticket encapsulates a hook and ISM that allows a Hyperlane message to be transported via Arbitrum's ArbSys precompile contract on L2 to L1. See more under https://docs.arbitrum.io/for-devs/cross-chain-messsaging

You will want to use a CCIP-read based ISM to allow the fetching of the OutboxProof data from the virtual precompile of the Arbitrum chain that can then be passed by any Hyperlane relayer to process the message on L1.

Submission of this bounty should include a demo on a testnet or mainnet with tx hashes.

Looks like no progress has been made, so I'd say you go for it

feat: support Arbitrum L2->L1 post dispatch hook (#3853)
f733379 
### Description

- Contract support for the enabling postDispatch hook with the Arbitrum
nitro bridge from L2 to L1
- asynchronously via executeTransaction call to verifyMessageId first
and then the relayer calling the verify message with no metadata (note:
this supports msg.value)
- synchronously via a single verify call which in turn calls
executeTransaction on outbox to gets the message verified in the
verifyMessageId (note: this doesn't support msg.value as ism.verify
isn't payable)
- Added a script for deploying the hook and ISM since the sdk doesn't
support it yet.

### Drive-by changes

- changing the type from "rate_limited_hook" to "RATE_LIMITED" to
maintain consistency

### Related issues

- fixes #2846

### Backward compatibility

Yes

### Testing

Unit and e2e with arbitrumsepolia->sepolia
