Or add it automatically from [Chainlist](https://chainlist.org/chain/698)

**Developers**\
For developers, we recommend using Ankr for reliable and scalable RPC endpoints. Visit <https://www.ankr.com/rpc/matchain/> for more details.

## **Adding Matchain Mainnet to MetaMask**

#### *Option 1: Automatic Addition*

1. Navigate to the [Rollup Info Page](https://rollup-info.altlayer.io/oram-primary-compromise/matchain_mainnet).
2. Click the "Connect Wallet" button.
3. Follow the prompts in MetaMask to add the Matchain network.

#### *Option 2: Manual Addition*

1. Open MetaMask and click on the network dropdown at the top.
2. Select "Add Network" and then "Add a network manually."
3. Enter the details listed above:
4. Click "Save" to add the network.

Looking for Testnet? For 99% of projects we would NOT RECOMMEND using Testnet, if you still need a testnet use [opBNB testnet](https://docs.bnbchain.org/bnb-opbnb/developers/network-faucet/).

## Network details

Matchain is identical to opBNB so we use opBNB testnet. [Faucet](https://docs.bnbchain.org/bnb-opbnb/developers/network-faucet/)
