How to add the Zero-Knowledge Rollups mainnet to MetaMask

Zero-Knowledge Rollups (ZK-Rollups) are a type of Layer 2 scaling solution for Ethereum that uses advanced cryptography to achieve significant performance improvements while maintaining the security of the underlying blockchain. By leveraging ZK-Rollups, users can enjoy faster and cheaper transactions without compromising the integrity of their assets. This guide will provide a step-by-step walkthrough on how to add the ZK-Rollups mainnet to your MetaMask wallet, enabling you to seamlessly interact with ZK-Rollup-based applications and services.

Prerequisites

Before adding the ZK-Rollups mainnet to MetaMask, ensure that you have the following:

• A MetaMask wallet installed as a browser extension or mobile app.
• Some ETH in your MetaMask wallet to cover transaction fees.
• A compatible ZK-Rollup provider, such as zkSync or StarkNet.

Steps:

1. Open your MetaMask wallet and click on the "Networks" tab.
2. Click on the "Add Network" button at the bottom of the list.
3. In the "Network Name" field, enter the name of the ZK-Rollup mainnet you wish to add. For example, "zkSync Mainnet" or "StarkNet Mainnet".
4. In the "New RPC URL" field, enter the RPC URL provided by the ZK-Rollup provider. For zkSync, the RPC URL is https://mainnet-api.zksync.io, and for StarkNet, it is https://alpha4.starknet.io.
5. In the "Chain ID" field, enter the chain ID of the ZK-Rollup mainnet. For zkSync, the chain ID is 1024, and for StarkNet, it is 31337.
6. In the "Currency Symbol" field, enter the currency symbol for the ZK-Rollup mainnet. For zkSync, the currency symbol is ZK, and for StarkNet, it is STARK.
7. In the "Block Explorer URL" field, enter the URL of the block explorer for the ZK-Rollup mainnet. For zkSync, the block explorer URL is https://zksync.info, and for StarkNet, it is https://starknet.io/explorer.
8. Click on the "Save" button to add the ZK-Rollups mainnet to your MetaMask wallet.
9. Your MetaMask wallet will now be connected to the ZK-Rollups mainnet. You can verify this by checking the "Network" dropdown at the top of the MetaMask interface, which should display the name of the ZK-Rollups mainnet you added.

Additional Notes:

This guide assumes that you are adding the zkSync or StarkNet mainnet to MetaMask. The steps may vary slightly if you are adding a different ZK-Rollups mainnet.

It is important to note that ZK-Rollup-based applications and services may require additional setup and configuration within MetaMask. Please refer to the documentation provided by the specific ZK-Rollup provider for detailed instructions on how to interact with their platform.
