Thanks to Founder Dom for double-checking this referendum. Even though the CG URL has changed, the "APP ID" of "hydradx" is still the same. Therefore vote NAY on this referendum. The corrected call has been re-submitted as https://interlay.subsquare.io/democracy/proposals/113.
While I understand the intention behind this referendum is to add more liquidity, adding volatile tokens as collateral increases the overall risk of the Interlay ecosystem and thereby the risk associated with iBTC. Therefore, I am voting Nay on this referendum.
