But I can lock through stake Dao and yearn without... @curvefi

Yes, it is possible to lock through Stakedao and Yearn without Curve.fi. You can either mint directly on either site, or you can swap your CRV directly on Curve for a 1:1 conversion rate. This is a great option if you are looking to quickly convert your CRV into other tokens. Additionally, you can take advantage of the liquidity pools available on Curve to maximize your returns. By locking your CRV on Stakedao or Yearn, you can earn rewards for staking or yield farming, depending on which platform you choose.

convert CRV on stakedao/yearn convex is 1:1

You can mint directly on either site, or swap directly on Curve (prot tip, do that)
