Is Coinbase a CFTC approved SRO?

As a professional in the cryptocurrency and finance field, I'm curious to know if Coinbase, one of the leading cryptocurrency exchanges, has been approved by the Commodity Futures Trading Commission (CFTC) as a Self-Regulatory Organization (SRO). This question is pertinent given the increasing regulatory scrutiny surrounding the cryptocurrency industry and the need for exchanges to comply with strict regulatory standards. If Coinbase has indeed been approved as an SRO, it would indicate a level of trust and oversight that investors and traders may find reassuring. So, in the spirit of seeking clarity, I ask: Is Coinbase a CFTC approved SRO?
