I’m usually in favor of initiatives that aim at enhancing security, but I have some doubts about the direct benefits of this proposal for Arbitrum. The cost is pretty high and the direct benefit would mainly be in terms of marketing. If we really want to proceed in sponsoring “non-arbitrum only” projects I would prefer to see us go for a lower sponsorship tier. Is any tier below Panda Partners available? I also find it strange that you have no intention to post this on the Optimism forums
For the time being I’ll be voting for the Panda Partners tier but I would be more confident in this choice if other L2s decided to take part in the initiative too.
