Yes, the percentage boost goes up when you lock CR... @curvefi

Answer 2: When you lock your CRV, you get an additional boost on your rewards. This is because locking your CRV allows you to earn additional rewards from staking and liquidity mining. By locking your CRV, you are able to receive rewards from the veCRV system, which is a reward system that pays out rewards to users who provide liquidity to the Curve platform. By locking your CRV, you are able to earn more rewards than you would without locking it.

Ah yeah thats right, you need to have veCRV to boost rewards. But its not necessary
