Dear CoolWallet users,
Below is a complete guide to show you How to manage your CoolWallet assets on MetaMask.


Step 1. Open your MetaMask Extension, tap the top-right icon, and select "Connect Hardware Wallet".

*If you haven't owned a MetaMask account, please create a "new one" first. (DO NOT import with your CoolWallet seed phrases in MetaMask, as this may pose a higher security risk).

Step 2. Select "QR-Based" and continue to Step 3.

Step 3. In CoolBitx APP, go to "MarketPlace", scroll down and tap "MetaMask".

Step 4. Tap "Synchronize wallet with MetaMask" and a QR Code will show up.

Step 5. On your computer, tap "Continue",  turn on your web camera, and scan the QR code on your phone.

Step 6. Select the ETH addresses you want to connect to, and tap "Unlock" (if you only have one ETH address, select the first account)
Important: Only use the accounts that have been added to your CoolBitX APP. You can add up to five empty accounts.

Step 7. Good, your CoolWallet account is now synchronized with MetaMask.

Step 8. Add Arbitrum or Polygon RPC, click "Ethereum Mainnet" (Default) > "Add Network" and input the following information:

1. Arbitrum

2. Polygon

3. BNB Chain (BSC)


Click on "Save" once you finished.

Step 9. All done! You can now manage your assets on these networks. Import tokens if you need to. Simply visit the following explorers, find the token address, copy, and paste it on MetaMask, and you're all set!

*Please note that customized tokens on Polygon & Arbitrum are only available on MetaMask. They cannot be managed in CoolBitX APP for now.

Notice: MetaMask extension only accepts one hardware wallet at a time. Tap "Forget Device" before you attempt to synchronize the second one.
