Download the MetaMask extension from the official website and install it in your browser. Fund it by transferring ETH from an exchange (like Coinbase) or another wallet.

Connect to a decentralized exchange (DEX) like Uniswap. Open the Uniswap website and click on "Connect Wallet". Then select MetaMask.

To swap ETH for $TIGRA, select ETH in the "from" field and choose $TIGRA in the "to" field using its official contract address. Enter the amount of tokens you want & press "Swap".

Verify your transaction status in MetaMask under the "Activity" tab. To see your new tokens, you may need to manually import the token to your MetaMask wallet by pasting in the $TIGRA contract address.
