Setting up your wallet to interact with the opBNB network is a crucial first step for anyone looking to explore decentralized applications (dApps), trade tokens, or engage in on-chain activities on this high-performance Layer 2 solution. opBNB, built on top of the BNB Smart Chain (BSC), offers faster transactions and lower fees—making it an attractive option for developers and users alike.
This guide will walk you through configuring popular wallets like MetaMask and Trust Wallet to work seamlessly with both opBNB Mainnet and Testnet. Whether you're a beginner or an experienced user, these clear instructions will help you get started quickly and securely.
Understanding opBNB and BNB Smart Chain
Before diving into setup steps, it’s important to understand the relationship between opBNB and BNB Smart Chain.
- BNB Smart Chain (BSC) acts as the Layer 1 blockchain that secures and supports opBNB.
- opBNB is a Layer 2 scaling solution designed to enhance speed and reduce gas costs while maintaining compatibility with Ethereum Virtual Machine (EVM) tools.
To use opBNB effectively, your wallet must be configured with both networks:
- The BSC network (Layer 1)
- The opBNB network (Layer 2)
Once configured, you can bridge assets from BSC to opBNB and begin interacting with dApps, NFT marketplaces, and DeFi protocols optimized for this fast-growing ecosystem.
How to Add BNB Smart Chain to Your Wallet
For MetaMask Users
- Open your MetaMask extension in your browser.
- Click on the network dropdown at the top and select "Add Network."
- Choose "Add a Network Manually."
- Enter the following details based on whether you're setting up Mainnet or Testnet:
BSC Mainnet
- Network Name: BSC Mainnet
- New RPC URL:
https://bsc-dataseed.bnbchain.org - Chain ID:
56 - Currency Symbol:
BNB - Block Explorer URL:
https://bscscan.com
BSC Testnet
- Network Name: BSC Testnet
- New RPC URL:
https://data-seed-prebsc-1-s3.bnbchain.org:8545 - Chain ID:
97 - Currency Symbol:
tBNB - Block Explorer URL:
https://testnet.bscscan.com

After entering the details, click "Save" to add the network.
For Trust Wallet Users
- Launch the Trust Wallet app or browser extension.
- Go to Settings > Network.
- Tap "Add Custom Network."
- Input the same configuration details listed above for either Mainnet or Testnet.
Once saved, you’ll be able to view BSC-compatible tokens and interact with BSC-based dApps directly from your wallet.
How to Add opBNB Network to Your Wallet
Now that BSC is set up, let’s configure your wallet for opBNB, the Layer 2 network.
Adding opBNB Mainnet
In MetaMask:
- Navigate to Settings > Networks > Add Network.
- Select "Add a Network Manually."
- Fill in the following:
- Network Name: opBNB Mainnet
- RPC URL:
https://opbnb-mainnet-rpc.bnbchain.org - Chain ID:
204 - Currency Symbol:
BNB - Block Explorer URL:
http://opbnbscan.com
In Trust Wallet:
Follow the same steps under "Add Custom Network" and input the above values.
Adding opBNB Testnet
Use the Testnet when experimenting with new dApps or testing smart contracts without spending real funds.
Configuration Details:
- Network Name: opBNB Testnet
- RPC URL:
https://opbnb-testnet-rpc.bnbchain.org - Chain ID:
5611 - Currency Symbol:
tBNB - Block Explorer URL:
http://testnet.opbnbscan.com
After adding, switch between networks easily using the dropdown menu in your wallet interface.
Tips for Optimal Wallet Performance
While the default RPC endpoints provided are reliable, performance may vary depending on your region. You can improve connection stability and reduce transaction latency by:
- Testing alternative RPC URLs published in official network documentation
- Monitoring node uptime and response times
- Using wallet settings to customize gas fees during periods of high congestion
Always verify RPC URLs from trusted sources such as the official opBNB documentation to avoid phishing risks.

Frequently Asked Questions (FAQ)
Q: Do I need BNB on both BSC and opBNB to use dApps?
A: Yes. You’ll need BNB on BSC to pay for bridging fees, and BNB on opBNB to cover gas for transactions within the Layer 2 network.
Q: Can I use the same wallet address on opBNB as on BSC?
A: Absolutely. Since opBNB uses EVM-compatible addresses, your wallet address remains identical across both networks.
Q: How do I get testnet tokens for opBNB?
A: Visit the official opBNB faucet (available through their documentation) and connect your wallet to receive free tBNB for testing.
Q: Is Trust Wallet fully compatible with opBNB?
A: Yes. Trust Wallet supports custom EVM networks, allowing full functionality with opBNB once correctly configured.
Q: What should I do if my transactions are stuck?
A: First, check the network status via the block explorer. If confirmed pending, adjust your gas fee and resend the transaction using MetaMask’s "Speed Up" feature.
