zkSync Era marks a significant milestone in the Ethereum scaling narrative as the first zero-knowledge Ethereum Virtual Machine (zkEVM) to launch on the mainnet. Developed by Matter Labs, this Layer-2 solution leverages advanced zero-knowledge rollup technology to offer faster and cheaper transactions while maintaining the security of the Ethereum mainnet.
This guide provides a comprehensive overview of zkSync Era, its features, how to get started, and what to expect from its growing ecosystem.
What Is zkSync Era?
zkSync Era is a Layer-2 scaling solution designed to enhance Ethereum's throughput and reduce transaction costs. It uses zero-knowledge rollups to bundle multiple transactions off-chain, generate a cryptographic proof, and then post that proof to Ethereum. This process ensures security and decentralization while significantly improving scalability.
The journey began with zkSync 1.0 (now called zkSync Lite), which launched in June 2020. Although it didn’t support smart contracts, it still achieved over $170 million in Total Value Locked (TVL), primarily in ETH and stablecoins like USDC.
zkSync 2.0 entered a "baby-alpha" phase in October 2022, introducing EVM compatibility and smart contract support. This version was rebranded as zkSync Era in February 2023, when project onboarding began. The network opened to all users on March 24, 2023.
How Does zkSync Era Work?
At its core, zkSync Era utilizes zk-rollup technology to process transactions off-chain. The system generates a succinct validity proof for these transactions, which is then verified on the Ethereum mainnet. This approach ensures that all transactions are secure and trustless.
One of zkSync Era’s key advantages is its EVM compatibility. Developers can write smart contracts in popular programming languages like Solidity, Vyper, and Yul, making it easier to port existing Ethereum applications.

How to Get Started on zkSync Era
To begin using zkSync Era, you’ll need a Web3 wallet and some ETH to cover transaction fees.
Step 1: Set Up a Wallet
The official zkSync Era bridge currently supports MetaMask, making it the most straightforward option for users. Other wallets may be supported via WalletConnect on some decentralized applications (dApps), but for bridging assets, MetaMask is recommended.
Step 2: Bridge Assets to zkSync Era
The most secure method to transfer assets is through the official zkSync bridge. Follow these steps:
- Visit the official zkSync bridge website.
- Connect your MetaMask wallet.
- Select the asset (e.g., ETH or USDC) and the amount you wish to transfer.
- Click “Deposit” and confirm the transaction in your wallet.
Alternatively, third-party bridges like Multichain and Celer also support zkSync Era, offering more options for users.
Step 3: Add zkSync Era to MetaMask
If zkSync Era isn’t automatically detected, you can add it manually using the following details:
- Network Name: zkSync Era Mainnet
- RPC URL: https://mainnet.era.zksync.io
- Chain ID: 324
- Currency Symbol: ETH
- Block Explorer URL: https://explorer.zksync.io/
You can also use platforms like Chainlist to add the network with one click.
The zkSync Era Ecosystem
Although zkSync Era is still in its early stages, several dApps are already live:
Decentralized Exchanges (DEXs)
- Mute: A DEX with swapping and liquidity pool features. It has already attracted significant TVL.
- SyncSwap & SpaceFi: Other DEXs that are operational on the mainnet.
NFT Projects
- zkApes: The first NFT collection on zkSync Era, with a mint price of 0.08 ETH.
- zkSync Name Service: Allows users to create personalized .zk domain names.
More projects are expected to launch soon, including major DeFi protocols like Uniswap, Balancer, and Aave.
The Future of zkSync Era
zkSync Era is positioned to play a major role in the expansion of zk-rollups. While optimistic rollups like Arbitrum and Optimism currently dominate the L2 landscape, zk-rollups offer advantages in terms of security and finality.
There is also speculation about a potential token airdrop. Although Matter Labs has not confirmed any token plans, the CEO has indicated that a token may be introduced when decentralizing the sequencer, which could be about a year after the mainnet launch.
Users looking to qualify for potential airdrops are advised to interact with protocols on both zkSync Era and zkSync Lite.
