The only way to know for sure when CRVUSD will be released is to keep an eye on the official Curve Twitter account or the Curve blog for updates. Additionally, you can reach out to the Curve developers directly to ask them when the launch date might be. It may also be helpful to keep an eye on the Votemarket platform to see if any incentives have been posted to speed up the process. Ultimately, the launch date of CRVUSD is out of anyone's control and the best way to stay informed is to keep an eye on the official sources of information.
