Hey everyone, reporting back from the Hyperlane team as promised in the above post. Here are answers to the UF’s questionnaire. Before we get started, we want to be clear, we are not proposing that Hyperlane should be picked as a standalone option, and only proposing it be considered as either an implementation option for the MMA design, or one of the options through an MMA design.

1. List 3 succinct reasons why you believe your bridge/solution would best serve Uniswap governance.

2. How long has the system been running on mainnet?

3. How much value has the system secured? (Current TVL, total transaction volume)

4. Provide a background on your team.

5. Please link your developer documentation.

6. Does the bridge support arbitrary message passing?

7. Has the current deployed bridge code been audited? By a third party? What attack vectors and vulnerabilities were identified, if any? Have the identified vulnerabilities been remedied?

8. Is there a bug bounty program?

9. List ANY portion of the functional bridge that is upgradeable and explain how the upgrade process works.

10. Do any contracts have an owner or owner-like entity? If so, what can the owner do?

11. What is the security model of the bridge? Please describe the security model for the current implementation of the bridge. What trust assumptions are you making?

12. How can an adversary pass a fraudulent message from Ethereum to the destination chain? Please give specific and concrete examples.

13. How can an adversary withhold a valid governance message from Ethereum to the destination chain? Please give specific and concrete examples.

14. What are the ramifications of fraud to the malicious actor(s)? If it is legal ramification, please share the suite of legal action you can provide. If it is slashing, please point us to the codebase of the slashing behavior and describe in words how slashing works in your system.

15. Provide any additional information you would like here.
