I’m supportive of this initiative to adopt the SEAL Safe Harbor Agreement for the ZkSync Protocol.
As a contributor to the Security Alliance, I’ve been providing feedback on the development of Safe Harbor since its early inception. It’s come a long way in maturity and is now being adopted by security platforms such as Immunefi. Its been recently adopted by major protocols including Origin and Compound Finance, the latter of which I was specifically involved in sponsoring as Compound’s Protocol Security Advisor. You can read more about my reasoning and the Immunefi proposal that led to its adoption on Compound here.
My only caveat is that I do believe that the circumstances of when whitehats can perform an exploit within Safe Harbor should be carefully considered and limited to very specific circumstances such as front-running a malicious exploit transaction that has been submitted to the mempool with no other option left to stop the attack. In any other scenario, whitehats should report exploits to the ZkSync Bug Bounty program on Immunefi so that issue mitigation can be managed by the Matter Labs team and/or Security Council.
