What is the Uniswap V3 address?

Excuse me, could you please clarify what the exact Uniswap V3 address is? I'm curious to learn more about the latest version of the decentralized exchange and how to interact with it directly. Is there a specific address I should be aware of for transactions or interactions with the protocol? I'm particularly interested in ensuring that I'm using the correct and up-to-date information for my cryptocurrency endeavors. Thank you for your assistance.
