How to Get opBNB: A Step-by-Step Guide

opBNB is a Layer 2 blockchain built on top of the BNB Chain using Optimism’s OP Stack. It’s designed to make blockchain transactions faster and cheaper, while still supporting Ethereum-compatible decentralized apps (dApps).

If you’re curious about using opBNB, this beginner-friendly guide will walk you through how to get started, from buying BNB to bridging it to the opBNB network.

How to Get opBNB, opBNB

What is opBNB?

opBNB is a scaling solution (Layer 2) for the BNB Chain. It processes transactions more efficiently by using optimistic rollups, which group transactions off-chain and then submit them to the main BNB Chain. This helps reduce congestion and gas fees.

  • BNB is the native token used on opBNB to pay for gas fees.
  • There is no separate “opBNB token.” When people say “get opBNB,” they mean using BNB on the opBNB network.
  • You’ll interact with BNB, but it will live on the opBNB network, not the regular BNB Smart Chain.

Here`s the step-by-step Guide on how to get opBNB:

Step 1: Buy BNB

Before you can use opBNB, you’ll need to own some BNB, which you’ll later bridge to the opBNB network.

  1. Create an account on a crypto exchange like:
  2. Buy BNB using your local currency or another cryptocurrency.
  3. Withdraw BNB to MetaMask:
    • Set your MetaMask to the BNB Smart Chain (BSC) network.
    • Copy your wallet address and withdraw BNB from the exchange to MetaMask on BSC, not Ethereum or other chains.

Step 2: Add opBNB Mainnet to MetaMask

To use opBNB, you need to add the opBNB network to your MetaMask wallet. There are two ways to do this:

Option 1: Manual Entry
Open MetaMask and enter these network details:

  • Network Name: opBNB Mainnet
  • New RPC URL: https://opbnb-mainnet-rpc.bnbchain.org
  • Chain ID: 204
  • Currency Symbol: BNB
  • Block Explorer: https://mainnet.opbnbscan.com

Option 2: Use ChainList

  1. Visit https://chainlist.org
  2. Search for “opBNB Mainnet”
  3. Connect your wallet and click “Add to MetaMask”

Adding the network allows your wallet to recognize opBNB balances and interact with opBNB dApps.

Step 3: Bridge BNB to opBNB

Now it’s time to move your BNB from the BNB Smart Chain to the opBNB network using the official bridge.

  1. Go to the opBNB Bridge: https://opbnb.bridge.bnbchain.org
  2. Connect your MetaMask wallet
  3. Select BNB Smart Chain as the source and opBNB as the destination
  4. Choose how much BNB you want to bridge
  5. Approve and confirm the transaction in MetaMask

After a few minutes, your BNB will appear in your wallet on the opBNB network.

What You Can Do With opBNB

Once your BNB is on the opBNB network, you can start exploring dApps and platforms built for fast, low-cost interactions.

Here’s what’s possible:

  • Swap tokens on decentralized exchanges (DEXs)
  • Use DeFi apps to lend, borrow, or earn yield
  • Explore NFT marketplaces
  • Play blockchain games that benefit from low fees
  • Try new projects in a cost-efficient way

opBNB is great for testing or using dApps without paying high transaction costs.

  • There is no separate opBNB token — you’ll use BNB on the opBNB network.
  • Always double-check links and network settings before connecting your wallet or sending funds.
  • Keep a small amount of BNB in your opBNB wallet for gas fees.

With this guide, you’re now ready to start exploring opBNB — a faster, cheaper gateway to the world of Web3 on the BNB Chain.
