Add the opBNB Network

Wallet configuration

You can use any Etheruem or BSC wallet with opBNB. For instance, I will show you how to set up Metamask for opBNB.

To configure your wallet to work with opBNB, you will need to add both the BNB Smart Chain (Layer 1) and the opBNB network (Layer 2).

Follow these steps:

1. Add the BNB smart chain to your wallet.

This is the Layer 1 blockchain that opBNB is built on top of.​

• Network Name: BSC Mainnet

• RPC URL: https://bsc.nodereal.io

• ChainID: 56

• Symbol: BNB

• Explorer: https://bscscan.com/

2. Add the opBNB network to your wallet.​

• Network Name: opBNB Mainnet

• RPC URL: https://opbnb-mainnet-rpc.bnbchain.org

• ChainID: 204

• Symbol: BNB

• Explorer: http://opbnbscan.com/
