yCRV is Yearn's improved veCRV wrapper system. New yCRV can be minted in two ways: Lock CRV to Yearn's veCRV position (permanent 1-way lock) or Migrate from legacy tokens yveCRV and yvBOOST. Both operations mint yCRV to the user at a 1:1 rate. Users migrating from yvBOOST can use the zap at y.finance to efficiently unwrap their tokens to yveCRV and migrates to yCRV in a single step. Of course, users can also choose to purchase yCRV from the new Curve factory pool.
