The answer to the question of whether crvUSD will be collateralized with CRV when it launches is uncertain at this time. While we have heard that crvUSD will most likely be collateralized with ETH, it is possible that CRV could also be used to collateralize crvUSD. This is something that the team behind crvUSD will have to decide and announce in the future. It is possible that the team could decide to use both ETH and CRV as collateral for crvUSD, or they could choose to use one or the other. Ultimately, it will be up to the team to decide which collateral they want to use for crvUSD.
