Answer: CRV tokens are used to provide liquidity to the Curve protocol, which is a decentralized exchange for trading stablecoin pairs. CRV tokens are used to incentivize liquidity providers to provide liquidity to the Curve protocol, as they receive a portion of the trading fees generated from the protocol. Additionally, CRV tokens are used to govern the Curve protocol, as token holders can vote on changes to the protocol through the Curve DAO. Finally, CRV tokens can also be used to access special features such as yield farming and staking rewards.
