Add Custom opBNB Mainnet Tokens to Your Wallet

Now that you have set up your wallet to use the opBNB network, let's proceed to add some smart contract tokens to the wallet.

Step 1: Obtaining the Token’s Contract

At the time of writing, the opBNB chain is newly launched and wBNB is the only official token on the network and the network’s explorer is yet to stabilize. Therefore, for this guide, we will use GeckoTerminal to track opBNB and obtain the smart contract address of WBNB.

Visit the opBNB page on GeckoTerminal and click on any WBNB pair.

Copy WBNB contract GeckoTerminal

Scroll down to the smart contract section and copy the WBNB contract. This process is the same for any other smart contract token you wish to add.

Step 2: Add the Token to Your Wallet

Go to your MetaMask wallet home page and scroll down to the bottom of the asset list. Click Import tokens and proceed to enter the asset’s details in the form that pops up.

Import Tokens on MetaMask

Paste the contract address for the WBNB token  in the designated input box; other details will load automatically.

Paste contract address

At time of writing, WBNB shows up as WETH – while this will probably be fixed soon, you can click Edit to change the name to WBNB. We will proceed to add without editing to differentiate from the natively added WBNB.

Edit token name

You can also opt enter these details manually.

Click Add custom token to add the token to your MetaMask wallet.

Complete by importing tokens

To complete, click Import token.

Step 3: Proceed to Transact WBNB From Your MetaMask

Transact WBNB from MetaMask

Your balances for the added token can be seen in your MetaMask wallet. You can also send and receive the asset as usual. Note that these transactions take place on the Layer 2 network.

To use your token on the mainnet, you will need to bridge them via the opBNB Bridge. Ensure that you have enough BNB on your source wallet to pay for the bridging fee.

Final Thoughts

Getting hands-on with new solutions like opBNB is important as the space tilts towards newer and more effective networks. opBNB promises an improved experience for users and the BSC network as a whole. Ensure to verify every detail and install the network properly before transferring assets and connecting them to external platforms.

This guide is specific to the MetaMask wallet. Note that these controls could differ for other wallet applications. In any case, ensure to read the proper guide before using the application, and confirm that all details are correct before sending funds. Also, be wary of the signed smart contracts and how they interact with your wallet. As a standard, always do your own research before interacting with smart contracts and investing in any cryptocurrency.
