How to Add zkSync to MetaMask

zkSync Overview

zkSync is a Layer 2 scaling solution for Ethereum, designed to enhance blockchain performance and usability. This solution is implemented through zero-knowledge rollup technology (zkRollups), which processes a large volume of transactions off-chain and subsequently records transaction data on the Ethereum mainnet. This approach maintains Ethereum's security while significantly improving transaction speed and reducing transaction costs.

As of late 2024, zkSync's total value locked (TVL) has reached approximately $800 million, establishing it as a major Ethereum Layer-2 network. zkSync's technical architecture provides fast and cost-effective transactions, making it a popular choice for developers and users. The zkSync ecosystem is expanding rapidly, now hosting nearly 200 decentralized applications (dApps), spanning decentralized finance platforms (DeFi), NFT marketplaces, and various other application types. The network continues to maintain steady user growth and significant on-chain activity.

MetaMask, as a leading Web3 wallet, is a preferred choice for users interacting with Ethereum and EVM-compatible blockchain networks. Since its launch, MetaMask has accumulated over 100 million users. It provides a secure and multifunctional platform that enables users to interact with various dApps within the zkSync ecosystem.

How to Add zkSync to MetaMask

Adding the zkSync network to MetaMask is a relatively straightforward process that can be completed by following these steps.

First, ensure that you have MetaMask installed. If you haven't already, please install MetaMask on your browser. You can download it from the MetaMask official website. MetaMask is available as a mobile application for Android and iOS devices, as well as a browser extension. After downloading, follow the installation instructions and set up your cryptocurrency wallet.

Once installation is complete, open your MetaMask wallet application. Click the account icon in the upper right corner and select "Settings" from the dropdown menu. In the Settings menu, click the "Networks" tab and then click the "Add Network" button.

On the page for adding a new network, enter the following details for the zkSync network:

• Network Name: zkSync
• New RPC URL: https://mainnet.era.zksync.io
• Chain ID: 324
• Currency Symbol: ETH
• Block Explorer URL: https://explorer.zksync.io/

After entering these details, click the "Save" button to confirm the addition. Once the network is successfully added, close the Settings menu. Click the network dropdown menu at the top of MetaMask and select "zkSync" from the list to switch to this network.

Using zkSync on MetaMask

After successfully adding the zkSync network to MetaMask, you can begin performing various operations on this network. The zkSync network allows users to interact with various applications deployed on it.

The process of sending and receiving tokens on MetaMask is convenient. To send tokens, click the "Send" button in MetaMask. Enter the recipient's blockchain address and the amount of tokens you wish to send. Before confirming the transaction, ensure that your wallet contains sufficient ETH to cover transaction fees. After verification, click the "Next" button, then click "Confirm" on the confirmation page to submit the transaction.

To receive tokens, you can share your wallet address with the sender. You can find and copy your wallet address by clicking your account name at the top of MetaMask. When the sender transfers tokens to your address on the zkSync network, the tokens will be deposited directly into your wallet.

Conclusion

Adding the zkSync network to MetaMask is a simple and straightforward process that can be completed by following the steps outlined above. As a Layer 2 scaling solution for Ethereum, zkSync provides faster and more economical transactions compared to the Ethereum mainnet, making it an ideal choice for many users and developers.
