In the fast-evolving world of blockchain technology, zkSync is emerging as a promising solution for addressing the scalability challenges of Ethereum. zkSync is a Layer 2 scaling solution that leverages zero-knowledge rollup technology to provide faster and cheaper transactions while maintaining Ethereum’s security and decentralization. Connecting zkSync to MetaMask, a popular Ethereum wallet, allows users to interact seamlessly with decentralized applications (dApps) on this layer-2 network. The integration of zkSync into MetaMask is a decisive step towards being able to interact with the network. In this guide, we’ll walk you through the steps to seamlessly integrate zkSync into your MetaMask wallet.

Alternative: Instead of adding zkSync from the list you can also click on “Add a network manually” at the bottom of the page. Proceed as follows:

4. Enter Network Details: In the new screen, enter the zkSync network details as follows:

  • Network Name: zkSync Era Mainnet
  • RPC URL:
  • Chain ID: 324
  • Currency Symbol: ETH
  • Block Explorer URL (Optional):

5. Save and Use: Click “Save” to add the network.

Adding zkSync to the MetaMask mobile app involves a similar process to the desktop version:

1. Open MetaMask App: Launch the MetaMask app on your mobile device.

2. Open menu: Tap on the network dropdown menu at the top of your screen and select “add network”.

3. Select Network: Search for zkSync Era Mainnet on the list and click “Add”. Check the network details on the screen and click “Approve”.

Alternative: Instead of adding zkSync from the list you can also click on “custom networks”. Proceed as follows:

4. Enter Network Details: In the new screen, enter the zkSync details as follows:

  • Network Name: zkSync Era Mainnet
  • RPC URL:
  • Chain ID: 324
  • Currency Symbol: ETH
  • Block Explorer URL (Optional):

5. Add and Switch: Add the network.

For developers or users interested in testing, adding an zkSync Testnet to MetaMask is beneficial. Be aware that several testnet options can be available.

1. Open MetaMask and Add Network: Follow the initial steps as described in the manual addition of zkSync.

2. Details for the zkSync Testnet (Sepolia):

  • Network name: zkSync Era Sepolia Testnet
  • RPC URL:
  • Chain ID: 300
  • Currency symbol: ETH
  • Block explorer URL:

3. Save and Switch: Save the settings to add the zkSync Testnet to your MetaMask.

In order for the tokens to be visible in the MetaMask, they must first be added. zkSync tokens are the equivalent of native ERC-20 tokens on Ethereum and represent a variety of assets and utilities within the zkSync ecosystem. Here’s how you can import zkSync tokens into your MetaMask wallet:

1. Access Your Wallet: Open MetaMask and ensure you’re on the zkSync network.

2. Find Token Contract Address: Locate the contract address of the zkSync token you want to add. This can usually be found on the project’s website or in the zkSync Block Explorer.

3. Add Token in MetaMask: Click on “Import tokens” at the bottom of the main MetaMask screen.

Why use the zkSync Network?

zkSync has gained attention for its innovative approach to Ethereum scaling. Here are some key reasons to consider using the zkSync network:

  1. Scalability and Speed: zkSync can handle thousands of transactions per second, significantly improving throughput compared to Ethereum’s mainnet. Transactions on zkSync are confirmed almost instantly, enabling quick and responsive interactions with decentralized applications.
  2. Low Transaction Fees: zkSync reduces gas costs by aggregating transactions and submitting them to Ethereum as a single proof, resulting in significantly lower fees for users.
  3. Security: zkSync inherits the security of the Ethereum blockchain using zero-knowledge proofs to validate transactions, ensuring that only valid transactions are recorded.
  4. User-Friendly: zkSync’s architecture allows users to interact with the network in a way that feels similar to using the Ethereum mainnet, with familiar tools like MetaMask. With easy onboarding tools like the zkSync bridge, users can transfer funds and start using the network quickly.
  5. Growing Ecosystem: More decentralized applications and DeFi protocols are integrating zkSync, providing users with a growing ecosystem to explore. zkSync offers robust tools and documentation to help developers build scalable applications, fostering an active and innovative community.

Jump Start for MetaMask CHANGE
