I do think this idea is worth pursuing further on the DPI product side. Redemption risk is the biggest barrier / concern to adding intrinsically productivity. Having a program in place first that locks staked DPI for 6 months / 1 year in place can reduce redemption risk to 0 given that the % AUV pursuing yield is always less than % locked in the contract. It also adds the ability for DPI constituents to be staked in native programs that lock up tokens for a period of time such as SNX, stAAVE, KNC etc, as long as the modules return the underlying to the DPI before the locking period expires.
Previously, the concern around @overanalyser 's 2% cash grab is that all DPI holders are exposed to the same redemption / liquidity risk through lending constituents and without a proper economic analysis, there wouldn’t be an optimal way to price what % of DPI assets should be staked elsewhere. By having an opt in locking mechanism, this segregates the risk of those who want a vanilla / redeemable DPI vs those who are in DPI for the long term (and of course there should be INDEX incentives associated to incentivize locking DPI to start).
Compared to the DPI yield farm, which is 2 separate products to segregate risk for customers, this is basically one DPI split into “sub-accounts” that segregate risk for customers.
