How To Connect MetaMask Wallet to Binance BNB Smart Chain

3 min readJul 11, 2021

Installing and setting up MetaMask

MetaMask can be downloaded on Microsoft Edge, Chrome and Firefox, or on iOS and Android if you’re a mobile user. For the purposes of this tutorial, we’ll use the Edge version, but the instructions will be more or less the same for every platform.

Firstly, you’ll want to head over to the MetaMask Download page. From there, select whichever platform you’re using, and follow the steps to install it on your device. Easy!

Next, click on the Metamask Icon on the right of your browsers address bar then follow along with the setup specified by the app. Go ahead and click Create a Wallet. Write down the backup seed phrase somewhere secret (not on an Internet-connected device). Without this phrase, your funds can’t be recovered if your device is damaged or lost. Confirm that you’ve written them down on the next page.

And that’s it! You should now see your wallet, ready to send and receive funds.

Configuring the wallet

You might notice straight away that we’re still dealing with an Ethereum wallet. At best, this won’t work with the BNB Smart Chain. At worst, you could lose funds by sending them to addresses you can’t actually use.

Let’s change that. We want to access the Settings to point the wallet towards BNB Smart Chain nodes.

First click on the circle in the upper right corner of Metamask.

Then choose Settings from the dropdown menu.

Select Settings from the dropdown menu.

On the Settings page, we want to locate the Networks menu.

Select Networks in the Settings Menu

We want to click Add Network to manually add the BNB Smart Chain one — it doesn’t come packaged with MetaMask.

Click on Add Network Button
Custom Networks Settings

Below are the parameters to fill in for each.


Network Name: BSC Mainnet


ChainID: 56

Symbol: BNB

Block Explorer URL:

Fill in Network Details as above.

Click Save. Next we need to change the Networks from Ethereum Mainnet to BSC Mainnet. Click on Ethereum Mainnet dropdown menu at the top of Metamask.

Ethereum Mainnet is still selected.

Next, select BSC Mainnet from the dropdown menu.

Select BSC Mainnet

Note the top dropdown menu has now changed to BSC Mainnet. We are now ready to receive our BEP-20 Tokens.

Network is now BSC Mainnet.

Next follow our instructions on How To Add the KOINU Token to Metamask.
