ZKsync Era is a ZK rollup layer 2 protocol for scaling Ethereum using zero-knowledge proofs, implemented primarily in Rust. It is EVM-compatible (Solidity/Vyper) and includes an LLVM-based compiler toolchain for smart contracts.

Use cases

• deploy a zk rollup layer 2 on ethereum
• run a zksync era node
• redeploy solidity contracts to a zk rollup without refactoring
• compile smart contracts to zero-knowledge circuits
• scale ethereum dapps with zk proofs
• fork a zk rollup for a custom chain

When to choose

• you need EVM-compatible smart contract deployment on a ZK rollup
• you want to operate or fork a production-proven layer 2 with active development and audits
• you need an LLVM-based compiler path for writing contracts in languages beyond Solidity

When to avoid

• you need a simple, low-complexity sidechain or optimistic rollup instead of ZK technology
• you cannot track security updates - the project warns that forking while in alpha risks missing critical fixes
• you only need to interact with Ethereum layer 1 without layer 2 scaling
