Is Velodrome on base?

Excuse me, could you clarify what you mean by "Is Velodrome on base?" Are you referring to a particular cryptocurrency platform or exchange named Velodrome? If so, and you're asking if it's operational and accessible, it would depend on several factors such as whether it's still active, whether it's been subject to regulatory scrutiny or bans in your jurisdiction, and whether there are any technical issues affecting its availability. If you're referring to something else entirely, could you please provide more context or clarify your question?
