Yes, having the ability to add liquidity to these pools would be great. There are quite some trading fees to be collected.

Even better if we can add the LP tokens to the Curve Gauges, and also earn CRV rewards (and additional token rewards).

Current rewards are really juice, and have been for quite some time!

For reference, current rates (incl. CRV rewards)

yPool = 22% APR

EURS = 47% APR

sUSD = 46% APR

USDN = 54% APR

AAVE = 37% APR

SETH = 32% APR

STETH = 84% APR

This is without vote-locking CRV to further boost rewards.
