Arbitrum/Orbit L2 => L1 Hook and ISM

Open nambrot opened this issue 2 years ago • 5 comments

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.

@nambrot is it still being worked on? Or would like to give it a try.

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

@exp7l want to claim this after you finish L1?
