Self-repaying loans paid down with LP token earnings / farming yield. This would diversify Alchemix's interest rate risk exposure by providing loans that leverage a different paydown mechanism, earned LP fees / farming rewards. I'm not a dev but I assume there would be quite a lot of complexities compared to the current Dai and ETH offerings.
To start, the protocol could use its ALCX/ETH reward pool, which could drive a nice flywheel effect to bootstrap the product concept. People see the current yield of 100% and want to participate. Demand goes up for ALCX because people are buying ALCX to LP against their ETH. They post their LP as collateral and take out alLP which is paid down with the ALCX rewards that are benefitting from rising demand for ALCX to LP. If the collateralization ratio alLP was something like 5:1, those loans would be paid down pretty quickly and potentially continue a virtuous cycle.
This all might be a crazy idea but wanted to share.
