Assuming you already have an account on Coinbase, go to the “Accounts” page on the Coinbase website. Find the section labeled “Your Wallets” and select Bitcoin from the list. On the next page, select “Send” and enter your MetaMask address in the “To” field.
NOTE: WARNING: Before attempting to transfer Avalanche from Coinbase to MetaMask, it is important to note that you must have an Avalanche wallet set up in MetaMask and must ensure that both Coinbase and MetaMask are compatible with each other. It is also necessary to double-check that the address you are transferring from is the same one as the one you want to send Avalanche tokens to. If any of these steps are not done correctly, there is a risk of losing your tokens permanently.
Enter the amount of Bitcoin you want to send in the “Amount” field and select “Continue”. On the next page, review the transaction details and select “Confirm”. Your Bitcoin will be sent to your MetaMask wallet!.
