Curve DAO is the DAO responsible for protocol governance and value accrual for the Curve Protocol.
Curve's main goal is to let users and other decentralized protocols exchange stablecoins (
USDC for example) through it with low fees and low slippage. Unlike exchanges out there that match a buyer and a seller, the behavior of Curve is different, it uses liquidity pools like Uniswap. To achieve this, Curve needs liquidity (tokens) which is rewarded by those who provide it.
Curve is non-custodial, meaning the Curve developers do not have access to your tokens.
The main purposes of the Curve DAO token are to incentivize liquidity providers on the Curve Finance platform as well as getting as many users involved as possible in the governance of the protocol.
Curve DAO has a token ($CRV) which is used for both governance and value accrual. Currently $CRV has three main uses: voting, staking and boosting. Those three things will require you to vote lock your $CRV and acquire $veCRV.
