To purchase a token on Ethereum using MetaMask, first set up your MetaMask wallet. Download the MetaMask extension from the official website and install it in your browser. Create a new wallet by following the prompts to set a password and secure your backup seed phrase. Once your wallet is set up, fund it by transferring Ether (ETH) from an exchange or another wallet to your MetaMask Ethereum address.

Next, connect to a decentralized exchange (DEX) like Uniswap, SushiSwap, or 1inch. Open the DEX website and click on “Connect Wallet,” selecting MetaMask from the options. Approve the connection in the MetaMask pop-up to link your wallet to the DEX. This will allow you to trade directly from your MetaMask wallet.

To swap ETH for your desired token, select ETH in the “from” field and choose your desired token in the “to” field. Enter the amount of ETH you want to swap, and the DEX will show the estimated amount of tokens you’ll receive. Click “Swap” or “Exchange,” then confirm the transaction in the MetaMask pop-up window. Make sure to review all details before finalizing the transaction.

Finally, verify your transaction status in MetaMask under the “Activity” tab or on Etherscan using your Ethereum address. If the token doesn’t appear in your MetaMask wallet, manually add it by clicking “Assets,” then “Add Token,” and entering the token’s contract address, symbol, and decimal. Your new tokens should now be visible in your MetaMask wallet, and you can manage, send, or trade them as needed.
