What is Coinbase vechainthor?

Could you elaborate on what "Coinbase vechainthor" refers to? As a professional in the field of cryptocurrency and finance, I'm familiar with Coinbase as a leading cryptocurrency exchange platform, but the term "vechainthor" seems to be a specific reference. Is it perhaps a feature, token, or integration between Coinbase and VeChain, a blockchain platform that specializes in supply chain management? Clarifying this term would help me provide a more accurate description and potentially discuss its relevance in the current cryptocurrency landscape.
