What Are the Key Features of zkSync Era?

✨
EVM Compatibility
Compatibility of the full Ethereum Virtual Machine allows Solidity/Vyper contracts to be deployed without changing their code through the use of the LLVM-based compiler.
✨
ZK Validity Proofs
The cryptographic proofs utilized in zkSync validate the transaction but do so while ensuring the security of Ethereum and do not require a trusted third party.
✨
Native Account Abstraction
The development of protocol-level enhancements to EIP-4337 has led to a much wider array of possibilities in terms of the kinds of functions that wallets can perform as well as the overall ease of use experienced by users.
✨
ZK Stack Modularity
A modular structure allows developers to create custom ZK chains that allow them to determine what is available to users (e.g., data availability), how tokens are used within their ecosystem (tokenomics) and how users interact with the chain (sequencing).
📊
State Diffs Optimization
Using output values from each transaction to update states results in greater cost savings than using calldata for updates.
✨
Low-Latency Proving
The combination of a high-performance ZK proof system and other optimizations have resulted in ~1 second network hops and minutes-to-Ethereum finality.
✨
Permissionless Smart Contracts
The ability to provide full smart contract composability via standard Web3 APIs, while maintaining most of the core EVM features.

Who Is zkSync Era Best For?

Best For

  • Ethereum users seeking lower transaction costs — With zkSync Era, the costs associated with using the platform are significantly less than those associated with using the mainnet, while still utilizing Ethereum's security model through the utilization of zero knowledge proofs.
  • DeFi protocol developers — The addition of full smart contract support to the platform enables developers to build complex DeFi applications and strategies that are compatible with the zkEVM.
  • High-frequency traders and applications — Faster finalization of transactions and lower costs for interacting with the blockchain provide better economic incentives for frequently performing on-chain interactions.
  • Projects building custom ZK chains — The ZK Stack Framework enables developers to create custom Layer 2 chains which share a common security model.

Not Suitable For

  • Users requiring maximum decentralization today — zkSync Era currently employs a centralized sequencer, however, if decentralized sequencing is necessary, consider either Arbitrum or Optimism.
  • Applications requiring instant finality — zkSync has proof generation latency. If you require sub second finality (i.e., if you need to be able to verify that a block has been added to the blockchain within seconds), consider using sidechains or validiums.
  • Teams unfamiliar with Ethereum ecosystem — Development of Layer 2 solutions requires knowledge of Layer 2 concepts as well as familiarity with Ethereum tools; if this is too complex, consider using a centralized exchange to transfer funds simply.

What Are Common Questions About zkSync Era?

zkSync Era is a Layer 2 zk- Rollup scaling solution designed for Ethereum. It supports both Solidity and Vyper Smart Contracts and offers significantly reduced transaction costs compared to Ethereum Main Net.

Due to the use of zk-Rollup technology, zkSync Era provides substantially lower transaction costs compared to Ethereum Layer 1. Transaction fees are denominated in ETH and depend on the degree of network congestion and the amount of gas used.

At present, withdrawals from zkSync Era main net to Ethereum Layer 1 have a 24 hour security delay following commitment. For updates regarding withdrawal status, refer to official tutorial materials and explorer resources.

Direct CEX (Centralized Exchange) transfers should not be used until the CEX has formally announced their support for zkSync Era. To avoid loss of funds when transferring assets, please utilize one of the third party bridges referenced on the zkSync Eco System Page to safely deposit/withdraw funds.

Yes, zkSync Era does offer fully generalized EVM compatibility in a permissionless manner. This means that dApps built for the Ethereum platform can migrate to the zkSync Era with only minor code modifications and maintain existing application states.

Yes, zkSync Era is the first zk-EVM chain to natively support Account Abstraction. This means that accounts can run arbitrary logic similar to Smart Contracts and initiate transactions such as those initiated by an External Owned Account (EOA).

zkSync Era is compatible with a number of popular Ethereum wallets including MetaMask, Trust Wallet, Zerion and Rabby. Please see the official documentation for instructions on how to configure zkSync Era in your preferred wallet.

Yes, zkSync Era has its own native token. Refer to the official documentation located at https://docs.zknation.io/zk-token for additional information on the ZK Token.

Is zkSync Era Worth It?

zkSync Era is a top-rated zkEVM Layer 2 that offers full Ethereum compatibility at a significantly lower cost than on L1 Ethereum. It does provide a "production-ready" version of layer 2 for Ethereum dApps; however, it has yet to reach full decentralization. Therefore, strong developer adoption, rapid ecosystem development, and its high degree of scalability place zkSync Era as a leading Layer 2 scaling option.

Recommended For

  • Developers building Ethereum-based dApps that are scalable
  • DeFi applications that require lower-cost transactions
  • Teams that want to leverage the EVM toolchain without changing their application codebase into bytecode
  • Applications that desire native account abstraction

!
Use With Caution

  • Users that need fast withdrawals from L1 (currently delayed 24 hours)
  • Applications that require immediate full decentralization
  • High-frequency trading platforms (first test performance)

Not Recommended For

  • Payment systems (zkSync Lite may be sufficient)
  • Non-EVM projects that need customized Virtual Machines
  • Cost-constrained projects that cannot afford to deploy an L2

What Are the Best Alternatives to zkSync Era?

  • •
    Starknet: Top zk-rollup built upon Cairo Language using STARK proofs. A more expressive form of proof than zkSync’s EVM compatible layer 2. Most suitable for teams looking to maximize both the expressiveness of their code and the level of decentralization of their application. (starknet.io)
  • •
    Polygon zkEVM: Type-1 zkEVM with full EVM equivalence and a large polygon ecosystem. Offers similar EVM compatibility, but uses a different sequencer model. Most suitable for projects that are already part of the polygon ecosystem. (polygon.technology/zkevm)
  • •
    Optimism: OP Stack is the leading Optimistic Rollup solution. Withdrawals can be made in less than one week; however, this comes with higher costs and the potential to transition to ZK in the future. This solution is ideal for teams that want to exit to L1 quickly. (optimism.io)
  • •
    Arbitrum: Arbitrum is the largest L2 ecosystem with Optimistic Rollups as its core technology. Arbitrum has the highest total value locked (TVL), and also has the most active developers but uses an optimistic security model. If you are looking to build on the largest L2 ecosystem, then Arbitrum is the best choice. (arbitrum.io)
  • •
    Base: Base is the first Layer Two (L2) on OP Stack, supported by Coinbase. With strong CEX integration and a consumer-focused approach, it offers fewer technical options than zkSync. The best option for those building for Coinbase or developing consumer applications. (base.org)
