How to use the Binance Chain to Binance Smart Chain Bridge

Some Exchanges (Coinspot, HitBTC, etc) trade BNB on the "Binance Chain Network". You will notice that the addresses on the Binance Chain Network will start with "bnb". These tokens will not be able to be transferred directly to wallets like Metamask or TrustWallet without doing a conversion to the Binance Smart Chain. This page will cover the conversion process using the Binance Chrome Extension.

Please Note: If you have an account on the Binance Exchange, then you can send your BNB coins there to convert.

Part 1: Download and Install Binance Chain Chrome Extension

1. Go to this address in your Google Chrome or other compatible web browser

Install Extension

• Click “Add to” to add to your browser’s extensions, then read the warning in the notification box and if you agree, click “Add extension”.

Accessing Extension

• The Binance Chain Wallet chrome extension is now accessible from the top of your browser whenever you may need it. You may choose to ‘pin’ it to the top bar by clicking the jigsaw piece icon and clicking the pin icon next to the extension.

Create and Secure Wallet

You may now choose to import an existing wallet or create a new one.

For the purpose of this guide; we will be creating a new wallet, as we are only using this extension to bridge between BEP2 and BEP20. It will not be our main wallet, we will transfer our BEP20 token to our Metamask wallet as the final step

• Create your wallet and select a strong password.

• Save your Mnemonic Phrase. This step is very important especially if you will be re-using this wallet/extension. If you do not properly backup this set of 12 words, you will have no way of recovering your wallet in the event of losing access to it!

• Press Continue to proceed to phrase verification

• Confirm your Mnemonic

• Congratulations — your BC Wallet chrome extension is now ready to act as a bridge for your BEP2 and BEP20 assets.

Part 2 Swapping BEP-2 to BEP-20

Now you will need to send your BEP2 asset to your new wallet from whatever exchange/wallet you have them on.

Sending your BEP2 to Binance Chain Extension Wallet
