Can you buy chain on Coinbase?

Could you elaborate on the possibility of purchasing chain tokens or coins through the Coinbase platform? I've been hearing a lot about chain-based cryptocurrencies and their potential, but I'm not sure if Coinbase supports their trading. Given Coinbase's reputation as a leading digital currency exchange, I'm curious if they offer the opportunity to buy and sell chain tokens. Would you be able to clarify if Coinbase indeed facilitates transactions in chain-based cryptocurrencies and if so, what the process entails? Thank you for your time and assistance in clarifying this matter.
