Does Coinbase use arbitrum one?

Excuse me, could you please clarify if Coinbase, the popular cryptocurrency exchange platform, utilizes Arbitrum One as a part of their infrastructure or services? I'm particularly interested in understanding if Coinbase has integrated Arbitrum One, the Ethereum scaling solution, into their platform to enhance transaction speeds, reduce fees, or improve user experience in any way. It would be great if you could provide some insights into this matter.
