The modular nature of Vesper enables strategies to route through other pools. This potentially enables many pools to upgrade simultaneously with a single upgrade to the pool that each routes through.
Maker-to-Vesper utilizes DAI loans via MakerDAO and vDAI to generate yield.
The pooled asset is deposited to a Maker vault as collateral
DAI loans are taken out against the collateral
DAI is deposited to vDAI
vDAI can utilize any strategies (likely direct-to strategies given the nature of DAI).
This strategy can be aggressive or conservative, depending on the collateral ratio employed and the strategies in place through vDAI.
