So I’m basing the USDC-ETH and WBTC-ETH as next on the fact that the community proposed them, they are very high on the Collateral Onboarding Prioritization Document, and the Domain Teams have already submitted the Oracle, Smart-Contract, and Risk Collateral Onboarding Assessments for them. The community already voted in USDC-ETH so all thats left is to put it in an Executive Vote. WBTC-ETH would still require a final Polling Vote. Notably these 2 pairs are also some of the highest liquidity Uniswap pairs which means they have the most demand.
I think promoting DAI liquidity is an interesting secondary benefit of the DAI based pairs. However, I think we still have to prove whether we can create demand for non-liquid LP pairs just by virtue of us adding them as collateral or whether we’re subservient to which pairs there is currently LP demand for. Until we confirm the former and can leverage it to bootstrap new DAI LP pairs, our resources are probably better spent taking the conservative approach and adopting LP pairs with existing demand.
Looking at the list of MIP6s, I see we already have applications for DAI-WBTC and DAI-YFI. Looking at which pairs actually have liquidity on Uniswap instead, I see DAI-USDC at 20M and DAI-USDT at 5M. There’s also some BAC and BAS based pairs with significant liquidity but those are highly risky to have exposure to. I think if someone submitted MIP6s for DAI-USDC and DAI-USDT those might be good pairs to target after WBTC-ETH and USDC-ETH.
