Curve allows users (and smart contracts like 1inch, Paraswap, Totle ) to trade between DAI and USDC with a bespoke low slippage, low fee algorithm designed specifically for stablecoins and earn fees. Behind the scenes, the liquidity pool is also supplied to the Compound protocol where it generates even more income for liquidity providers.
Has Curve been audited?
Curve smart contracts were Audited by Trail of Bits.
However, security audits don't eliminate risks completely. Please don’t supply your life savings, or assets you can’t afford to lose, to Curve, especially as a liquidity provider.
Using Curve as an exchange user should be significantly less risky, but this is not advice.
How do I trade on Curve?
Before trading, you’ll have to approve Curve to interact with your stablecoin balance, similar to most DeFi applications.
On the exchange page, select the asset you would like to convert (e.g. USDC), and the quantity (e.g. 1,000) - the exchange rate, and quantity that you will receive (including and all slippage and fees) will be displayed. The exchange rate might surprise you - that’s the power of Curve.
Fees
Fees and pool parameters are decided by the Curve DAO.
Currently, the fee on all pools is 0.04%, of which 50% goes to liquidity providers, and 50% to veCRV holders (members of the DAO).
How to withdraw liquidity I provided?
Go to the withdraw page. If you want to withdraw some percentage of your liquidity (the preferred way), type that percentage in the top field. You can, however, withdraw in a form of individual coins (USDC, DAI, ...), having the exchange happening for you, if you type amounts in lower fields. You'll get charge with the exchange fee in the latter case.
