Currently OUSD’s Curve 3Pool strategy uses the official Curve gauge to stake 3CRV LP tokens in. By switching to staking 3CRV with Convex, we would expect to get approximately a 2.5x increase in strategy APY. This gain is from the Convex CRV boosting as well as selling CRVX reward tokens.
This would add some risk exposure from adding another project as a dependency. However Convex is from the same team behind Curve, and currently Convex has 4.8 billion dollars in it.
