Step 1: Create a wallet -
Metamask.io is the best one.
Step 2: Get some Ethereum. You can buy it either directly from metamask or transfer from a centralized exchange like Binance or Coinbase.
Step 3: Visit Uniswap (
App.uniswap.org), connect your wallet and paste $Fren contract address in the "select token" field.
Step 4: Swap your Ethereum for $Fren coins - after choosing the amount of Ethereum you wish to swap for $Fren, adjust slippage to 1.2%, click swap and confirm the transaction in your metamask wallet.
