firstly i cant believe that i have just now stumbled into this proposal.
Dai is a scarce asset, look at ALCX, they hold 10% of the existing Dai supply and have deposited it all in yDai.
Having ETH as a Bond might cause an issue with regards to existing pools. my recommendation is to keep the pool as is DAI/OHM with no additional OHM/ETH pool. the current pool has low liquidity as seen from recent price volatility.
Using ETH to purchase OHM should come directly from the protocol, and i believe the protocol should keep the ETH as is and not go through the direction of CDP.
Against CDP for the reasons below:
diversification of the DAO treasury
DAO holds
1) DAI (non-yielding)
2) SUSHI (through onsen rewards)
future
ETH
other US$ pegged stable coins (FRAX, alUSD, USDC)
The plan should be to keep the treasury as risk free as possible and that is by either keeping them in:
1) Wallet
2) Yearn Vaults (yETH and yDAI)
3) Compound (to earn Comp tokens as well as interest income)
4) AAVE ((to earn stkAAVE tokens as well as interest income + possible to take them to L2 and earn MATIC on top of the above)
5) deposit the DAI in CRV, and earn on trading fees as well as CRV tokens (we could in the future introduce an in house yvBOOST similar to what Yearn deploy to incentives users to provide them with CRV tokens to earn the 2.5x boost)
the main issue is how the DAO will value the ETH?
my immediate thought is that it should treat it the same way MKR would when minting DAI, and in this case minting OHM. at 150% collateral + no need for the stabilization fee.
