The DAO can use the Yearn.finance stETH vault to earn approx 4.8% APY (as of 3/22/22). This proposal will put 50% of Yam’s Treasury ETH into the pool.
Yam’s treasury currently holds 277 ETH which is currently idle. Investing would give a small amount of yield until better yields or investments could be found.
The YAM treasury (Yam.Finance: Treasury | Address 0x97990b693835da58a281636296d2bf02787dea17 | Etherscan) currently holds ~277.5 WETH. The proposal is to deploy approx. half of it (139 WETH) to the stETH yearn vault (yearn: yCRV/stETH Vault | Address 0xdCD90C7f6324cfa40d7169ef80b12031770B4325 | Etherscan) in the next on-chain transaction.
