Curve Finance tweeted that after some peer-review of deployments, it was found that the current version of crvUSD needs a redeployment which will follow shortly today. In addition, veCRV wouldn't get fees with this one, due to a mistake in the deployment script.
Previously, Curve announced that the smart contracts of its native stablecoin $crvUSD have been deployed on the mainnet. The public release is not finalized yet because UI still needs to be deployed.
