The main purpose of Convex Finance is to increase the distribution of users' CRV income by optimizing Curve Finance's gauge voting (boost), without users having to operate Curve Finance themselves.
CVX is the native token of the project.
Current use cases of CVX include:
Staking: Users can stake CVX tokens on the Convex Finance platform to obtain a portion of the platform fees
Liquidity mining: Users can provide CVX to liquidity pools outside of Convex Finance,
to obtain liquidity mining rewards and a portion of DEX transaction fees (such as Sushiswap)
Voting: Users can lock CVX tokens on the Convex Finance platform to vote on the CRV issuance of Curve Finance gauges.
