I have been messing with it for a few hours. I cannot figure out how to buy Saitama Inu with it. As you can see above, I have seen videos on how to do it, but I cannot find the token on MetaMask even by listing the address manually, etc.
You need to copy and paste the contract address from CoinGecko or CoinMarketCap to Uniswap. Are you trying to in-app swap for Saitama Inu?
