**zkSync is an Ethereum Layer 2 scaling solution that offers low transaction fee, highly secured and fast transactions**.

**zkSync 1.0** has been live in the mainnet almost 1.5-2 years. It provides a lot of great benefits for Defi users. Now, It’s important to know that **zkSync 2.0** already lived on the testnet since around Feb 2022.

**What’s zkSync 2.0?**

zkSync 2.0 is the first time that zkSync will be EVM compatible for Zero Knowledge rollups on Ethereum. It allows developers to build and deploy decentralized applications (dapps) with low transaction fee and highly scalable Layer 2 by using Solidity which is native programming language on Ethereum.

EVM compatibility has a lot of advantages and great impact in early implementations of L2 solutions. That means the moving forward from Ethereum to zkSync 2.0 will be simple than ever and of course zkSync 2.0 provides great efficiency and scalibility.

The design of zkSync 2.0 maximizes the combination of the following 2 technologies.

*   zk EVM: The EVM-compatible zkRollup which adopts L1 security and solidity smart contract support.
    
*   zkPorter: The off-chain data availability system which offers more scalability than rollups. It offers ultra low fees like side-chain.
    

**zkSync 2.0 key highlights**

*   Similar to mainnet security.
    
*   EVM-compatible smart contracts.
    
*   Using standard Web3 API.
    
*   Introducing some of new features such as account abstraction and meta-transactions
    

**zkSync 2.0 testnet walkthrough**

As mentioned that zkSync 2.0 has already lived on testnet for users in Feb 2022. What users can do now shall follow the following steps:

1\. Add zkSync 2.0 testnet on Metamask.

      1.1 Network Name: `zkSync alpha testnet`
    
      1.2 New RPC URL: `https://zksync2-testnet.zksync.dev`
    
      1.3 Chain ID: `280`
    

2\. Visit [https://portal.zksync.io/](https://portal.zksync.io/)

3\. Click faucet to obtain some test tokens such as USDC, wBTC, LINK and DAI.

4\. Use one of the Goerli Faucets to get Goerli ETH

      4.1 https://goerli-faucet.mudit.blog/
    
      4.2 https://faucet.paradigm.xyz/
    

5\. Click bridge to deposit some ETH from Ethereum Goerli to zkSync Goerli testnet.

6\. Click wallet and select “transfer“ or “receive“ where you can transfer assets to another zkSync wallet address or tell others send assets to your address.

7\. Click bridge to withdraw some ETH from zkSync Goerli testnet back to Ethereum Goerli if needed.

**Mute testnet on zkSync 2.0**

Mute, which is a ZK Rollup based automated market maker (AMM), farming platform, and IDO platform, also lived on zkSync 2.0 testnet.

Users can follow these steps.

1\. Visit [https://testnet.switch.mute.io](https://testnet.switch.mute.io)

2\. Swap assets and Add liquidity for available pairs of token.
