How to Set Up a MetaMask Wallet
If you don't already have MetaMask, it can be downloaded on Chrome, Firefox, or on your mobile device.
Head over to the MetaMask Download page, then select your browser or device, click the install MetaMask button, and follow the steps to download. Then continue through the setup as specified. This will vary slightly depending on your device.
During setup, you can use an existing wallet by importing your Secret Recovery Phrase, or generate a new recovery phrase to set up a new wallet. Be sure to write this down! A strong password is great, but if you forget it or lose access to your device, your recovery phrase will be needed to regain access to your wallet.
For extra security, we'd recommend not saving this on an internet-connected device. A notebook or sheet of paper you won't lose track of would be best. You'll need to confirm that you wrote these down, and in the correct order, during the process.
If you lose this phrase, there will NOT be a way to recover your wallet and any funds in it. You are in complete control of your funds here, but with power comes responsibility!
After your phrase is confirmed, your wallet is set up.
Configuring your MetaMask Wallet for BNB Smart Chain
By default, MetaMask will be set up as an Ethereum wallet, able to accept ETH and any ERC20 tokens on the Ethereum network. You might notice that the address begins 0x just like BNB Smart Chain (BSC) addresses. These are not interchangeable, however, and any funds sent on the Ethereum network to a BNB Smart Chain (also known as BEP20) address or vice versa could be lost.
This is why if you'd like to withdraw a token to MetaMask from your Binance.US account using the BNB Smart Chain (or use the BNB Smart Chain network to deposit to your Binance.US account), we'll need to configure MetaMask for the BSC network. To do so, head up to the Networks dropdown menu where it currently says "Ethereum Mainnet" and select Add Network.
From here, we'll need to select the Networks Menu from the left sidebar, then click the Add a network button in the top right.
We'll need to manually add the information for BNB Smart Chain, as it is not included in MetaMask by default. The information needed to add BNB Smart Chain to your wallet is:
After adding in this info, click the Save button.
You can also add the Testnet, though this is generally used by developers for testing purposes before launching on the Mainnet. Tokens in testnets do not hold any value, as opposed to mainnet tokens which use real assets and cryptocurrencies;
You'll then be taken back to the home-screen, where you'll now be connected to the Smart Chain. You can always switch back to the Ethereum network for ERC20 transactions by selecting it from the drop-down menu in the top right.
