# 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.**[**​**](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/wallet-configuration#mainnet)

* Network Name: BSC Mainnet
* RPC URL: [https://bsc.nodereal.io](https://bsc.nodereal.io/)
* ChainID: 56
* Symbol: BNB
* Explorer: <https://bscscan.com/>

### **2. Add the opBNB network to your wallet.**[**​**](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/wallet-configuration#mainnet-1)

* Network Name: opBNB Mainnet
* RPC URL: [https://opbnb-mainnet-rpc.bnbchain.org](https://opbnb-mainnet-rpc.bnbchain.org/)
* ChainID: 204
* Symbol: BNB
* Explorer: <http://opbnbscan.com/>

## How to configure Metamask[​](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/wallet-configuration#references---how-to-configure-trustwallet-or-metamask) <a href="#references---how-to-configure-trustwallet-or-metamask" id="references---how-to-configure-trustwallet-or-metamask"></a>

1. Install [MetaMask](https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn)
2. After you install the metamask in your browser, you can go to \[Settings] -> \[Networks] -> \[Add Network] page.
3. Select add manual network and enter the network information.

### opBNB RPC Endpoints[​](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/opbnb-network-info#opbnb-rpc-endpoints) <a href="#opbnb-rpc-endpoints" id="opbnb-rpc-endpoints"></a>

You can use either public and private RPC endpoints to access opBNB.

**Public opBNB Mainnet RPC Endpoints(WSS is supported)**[​](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/opbnb-network-info#public-opbnb-mainnet-rpc-endpointswss-is-supported)

**Private opBNB RPC Endpoints**[​](https://docs.bnbchain.org/opbnb-docs/docs/build-on-opbnb/opbnb-network-info#private-opbnb-rpc-endpoints)

NodeReal supports the opBNB network, you can create your free opBNB RPC endpoints with your github or discord.

**NOTE**

To use the above private RPC endpoint, make sure to login to [MegaNode service](https://nodereal.io/meganode) and create your private endpoints.
