Hello there, I'm curious about purchasing Grok tokens on UniSwap. Could you please walk me through the process step-by-step? I'm a bit new to decentralized exchanges and would appreciate if you could explain the prerequisites, such as what wallet I should use and how to connect it to UniSwap. Additionally, could you provide any tips or precautions to keep in mind during the transaction to ensure a smooth and secure process? Thank you in advance for your guidance.
