Curve Finance (CRV) has switched its fee distribution from the 3crv token to its own stablecoin, crvUSD. The change aims to increase crvUSD's utility and integrate it into the Curve Finance ecosystem. The shift to crvUSD will simplify the process for users, as the stablecoin doesn't need to be converted to be used in Curve Finance products. The distribution of fees in crvUSD will also encourage users to engage more with products and services that use it. Curve Finance is addressing potential liquidity concerns and risks associated with the transition.
