ZKsync Era is a ZK-rollup Layer 2 on Ethereum built by Matter Labs that achieved a critical milestone: full EVM compatibility with zero-knowledge proof security — meaning any Solidity smart contract can deploy on ZKsync Era without modification, while benefiting from ZK-proof-based security and low fees. ZK is the governance token launched in June 2024 via one of the largest airdrops in crypto history (3.6 billion ZK tokens to 695,000 wallets). ZKsync pioneered the ZK-rollup space alongside StarkWare, and was the first project to demonstrate production-ready ZK proof generation for EVM-equivalent execution. Matter Labs raised $458M in funding from a16z and other top-tier VCs to build ZKsync.

How It Works
ZKsync Era architecture:
- Sequencer: Orders transactions (initially Matter Labs, decentralizing)
- Provers: Generate zk-SNARK proofs for transaction batches
- Verifier (Ethereum): Verifies proofs; updates state root on Ethereum
- Boojum proof system: ZKsync’s custom, high-performance SNARK proving system (upgraded from PLONK)
EVM equivalence:
ZKsync Era achieves EVM equivalence — Solidity/Vyper contracts compile to intermediate representation and then to ZKsync’s circuits. This means developers get ZK security without rewriting contracts in a new language (unlike StarkNet’s Cairo).
Native account abstraction:
ZKsync Era has native account abstraction at the protocol level (not as an add-on like ERC-4337 on Ethereum), enabling smart contract wallets and sponsored transactions as first-class features.
ZK Stack:
ZKsync’s framework for building custom ZK-rollup chains (“hyperchains”) that interconnect with each other and Ethereum. Similar to Optimism’s OP Stack but ZK-based.
Tokenomics
| Metric | Value |
|---|---|
| Max Supply | 21,000,000,000 ZK |
| Airdrop | 3.675B ZK (17.5% supply) to users |
| Ecosystem | 49.1% (foundation reserve, grants) |
| Team | 16.1% |
| Investors | 17.2% |
Use Cases
- Governance — ZKsync DAO voting on protocol decisions
- Gas fees — ZK token used for Era gas fees (along with ETH)
- Hyperchain — Coordinating ZK Stack hyperchains
- Ecosystem incentives — Funding ZKsync ecosystem development
History
- 2018 — Alex Gluchowski founds Matter Labs
- 2020 — ZKsync 1.0 launches (payments only, no smart contracts)
- 2022 — ZKsync Era mainnet launches with full smart contract support; first EVM-compatible ZK rollup
- 2023 — ZKsync Era TVL grows to $800M+; hundreds of DeFi protocols deploy
- Jun 17, 2024 — ZK token launches via massive airdrop (695K wallets receive ZK); controversial sybil filtering; significant community criticism of allocation fairness
- 2024 — ZK continues ecosystem growth; ZK Stack hyperchains launch (Lens Network, Cronos ZK, etc.)
Common Misconceptions
“ZKsync and zkEVM are the same thing.” Multiple ZK-rollups offer “zkEVM” implementations (Polygon zkEVM, Scroll, Linea, etc.). ZKsync Era was first to mainnet but is one of several EVM-compatible ZK rollup options.
“The ZK airdrop was fair.” The ZK airdrop was heavily criticized — 695K wallets received tokens, but many sybil accounts reportedly still received tokens while some genuine users were excluded. Matter Labs acknowledged issues with the sybil detection criteria.
