With regards to SaaS contention:
I’m not fully sure yet on if the trust side of things of the smart contract should lean fully on the oDAO or on the SaaS provider.
But apart from that, as an institution we see high interest in ETH staking from various entities but they do not want exposure to a relative unknown and high risk ERC-20 token like RPL. By design RPL is needed to run minipools (or at least to be able to get RPL rewards as well). But the ROI via Rocket Pool is higher compared to solo staking of course.
Ideally we’d like to stake ETH on behalf of our customers while also having the opportunity to attract RPL from the open market (anons) (and custodial as well). In this way it can be a win-win for both parties in my opinion.
