Interest/Staking/Passive Income?

Is there anywhere we can stake or hold our index holdings and earn interest? The underlying tokens on these indexes are highly liquid, have incentives and can be held to earn interest if we owned the underlying coins itself. Is there anyway to benefit from this? I see there is a proposal to turn back on staking, but it’s through the Ethereum mechanism which opens us up to IP. Who is running, or is this a community led project?
