Compound has several stablecoins and I get that lending them out may risk them. But the DAI itself is tied to Spark so if Spark fails DAI basically fails so there doesn’t seem to be a point in keeping it in storage. I believe the APR is currently 6% on DAI, that’s 23.361 mil DAI making 1.4 million a year. There’s also close to 3 million eth that should probably be staked but the difficulty is who to to stake it, perhaps the withdraw keys themselves can be held and a staking service can be used with just the staking keys (sorry if I used the wrong name for the keys I forgot what they are called specifically).
There is also 30+ million in USDC…I assume that can be the first to be airdropped to COMP holders but also maybe the part that isn’t airdropped in the first year can be deposited with Compound?
