Layer 2 & Scaling

Zksync Era

An open-source Rust repository implementing an Ethereum Layer 2 rollup that uses zero-knowledge proofs to scale Ethereum. It is EVM-compatible and supports Solidity and Vyper smart-contract development, with an LLVM-based compiler intended to support additional languages.

Understand the project

Practical overview

When it fits

Use it for Ethereum scaling work, ZK-rollup development, EVM-compatible smart contracts or investigation of rollup infrastructure. A custom deployment based on the repository is Likely compatible, subject to the documented risk of missing security updates, critical features and performance improvements.

Who it is for

  • Developers building or evaluating Ethereum Layer 2 infrastructure
  • Teams working with ZK rollups, smart contracts or Ethereum scaling
  • Engineers exploring custom rollup deployments and smart-contract tooling

Documented uses

  • Deploy Ethereum-compatible smart contracts on a ZKsync Era-based Layer 2
  • Develop tooling for Solidity and Vyper deployments
  • Experiment with the LLVM-based smart-contract compiler
  • Adapt rollup components for a custom Layer 2 deployment
Before you choose

Requirements & limits

The repository is public and active. It targets Linux, server and self-hosted environments. Licensing is documented as Apache-2.0 or MIT.

  • Ethereum ecosystem and EVM compatibility are central to the project
  • The primary implementation language is Rust
  • Zero-knowledge proofs provide the rollup’s scaling approach
  • The LLVM-based compiler may support work beyond Solidity and Vyper
  • Forking for a custom deployment requires attention to potentially missing updates, features and performance improvements

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
