zkSync Era is an Ethereum L2 network built on zero-knowledge proofs, developed by the Matter Labs team. You can check ZK token prices on the Binance Official Site, download the Official Binance App to trade zkSync ecosystem assets, and if you're on an Apple device, check the iOS installation guide first. zkSync Era's mainnet launched on March 24, 2023, and its defining feature is using SNARK proofs to verify every batch of transactions on the Ethereum mainnet, cutting withdrawal times from the 7 days typical of Optimistic Rollups down to just a few hours. As of April 2026, zkSync Era's TVL sits at roughly $2.8 billion, the highest among ZK Rollups.
zkSync Era's process runs in four steps. First, a user submits a transaction on zkSync Era, which is received and executed by a sequencer operated by Matter Labs. Second, the sequencer batches the transactions together and calls on Prover nodes to generate a ZK-SNARK proof, proving that the batch was executed correctly according to Ethereum Virtual Machine rules. Third, the proof, the state root, and the transaction data are all sent together to the zkSync contract on the Ethereum mainnet. Fourth, the mainnet's Verifier contract spends about 15,000 gas (roughly $0.50) to verify the ZK proof, and once it passes, the state is formally confirmed by the Ethereum mainnet.
The core innovation running through this whole process is "replacing re-execution with a single proof." The Ethereum mainnet doesn't need to re-run every transaction that happened on zkSync — it only has to verify one mathematical equation, the ZK proof. This approach means zkSync Era's throughput can theoretically reach 2,000+ TPS, while verification costs stay nearly constant.
Generating a ZK-SNARK proof is a computationally intensive task. Matter Labs uses dedicated, GPU-accelerated Prover clusters to generate proofs in batches, with each batch covering 1,000-5,000 transactions and taking 5-15 minutes to generate. The generation cost runs about $50-200 per batch, but spread across individual transactions, that comes out to just $0.01-0.05 each.
zkSync Era represents the ZK Rollup camp, standing opposite Arbitrum and Optimism's Optimistic Rollup approach — the two major schools of thought in the L2 world. The table below compares the key differences.
| Dimension | zkSync Era (ZK Rollup) | Arbitrum/Optimism (Optimistic Rollup) |
|---|---|---|
| Security model | Mathematical cryptographic proofs | Economic incentives + 7-day challenge period |
| Mainnet to L2 deposit | A few minutes | 10-15 minutes |
| L2 to mainnet withdrawal | 1-3 hours | 7 days |
| Per-transaction gas fee | $0.06 | $0.05-0.10 |
| Proof generation cost | High (GPU clusters) | Low (only when challenged) |
| Throughput | 2,000 TPS | 250 TPS |
| EVM compatibility | Compatible (not equivalent) | Equivalent |
The core advantage of ZK Rollups is fast withdrawals and mathematically grounded security. Withdrawing USDC from zkSync Era to the mainnet typically takes 1-3 hours, far faster than Arbitrum's 7-day wait. But ZK Rollups have two weak spots: first, weaker EVM compatibility than Optimistic Rollups (zkSync uses its own zkEVM, and some opcodes need to be adapted); second, the hardware cost of proof generation is high, currently relying mainly on NVIDIA H100 and A100 GPUs.
zkSync Era's technical evolution revolves around three core goals: EVM compatibility, lowering proof generation costs, and decentralizing the sequencer.
| Date | Upgrade | Impact |
|---|---|---|
| 2023-03 | Era mainnet launch | SNARK proof system goes live |
| 2023-09 | Boojum upgrade | Prover performance improves 10x |
| 2024-02 | EIP-4844 integration | Gas fees drop 80% |
| 2024-06 | ZK Stack open-sourced | Any team can build a ZK chain on top of ZK Stack |
| 2024-12 | Validium mode | Support for low-cost data availability options |
| 2025-06 | Boojum 2.0 | Proof generation speed improves another 5x |
| 2026 roadmap | Sequencer decentralization | First batch of shared sequencer nodes goes live |
Boojum is zkSync Era's proprietary proof system, using RedShift (FRI) polynomial commitments, which offers a significant performance edge over the earlier Plonk-based system. Boojum 2.0 lets zkSync Era process up to 10,000 transactions per batch, with proof generation time down to 3-5 minutes.
ZK Stack is the modular ZK chain framework that Matter Labs open-sourced in 2024, occupying a role similar to what OP Stack holds within the Optimistic Rollup camp. Teams can use ZK Stack to quickly spin up custom ZK Rollups or ZK Validiums, with all ZK chains sharing a common ZK proof infrastructure and cross-chain liquidity layer.
More than 50 projects are currently building on ZK Stack, including GRVT (a compliant perpetuals chain), Cronos zkEVM (Crypto.com's chain), Lens Network (a social chain), and Treasure (a gaming chain). This "superchain" model gives the zkSync camp a strong position in the wave of application-specific chains.
zkSync airdropped its ZK token in June 2024, with 17.5% of total supply in circulation right after TGE. The token allocation breaks down as follows.
| Category | Share | Notes |
|---|---|---|
| Community airdrop | 17.5% | Distributed once to early users |
| Ecosystem fund | 19.9% | Ecosystem incentives decided by the DAO |
| Team | 16.1% | 4-year linear unlock |
| Investors | 17.2% | 4-year linear unlock |
| Matter Labs (the company) | 16.1% | 4-year linear unlock |
| Token house | 13.2% | Governance treasury |
The ZK token's core use case is governance plus sequencer economics. The actual value-capture mechanism for the ZK token is still under DAO discussion, and there's no clear buyback-and-burn model yet, unlike Arbitrum. That's the core reason ZK's short-term valuation has stayed relatively weak.
The ZK token's initial unlock schedule was fairly aggressive — a large share of investor allocations began unlocking within a year of the June 2024 airdrop, and team unlocks started in June 2025. This unlock pace has kept the ZK token's price under pressure through 2024-2025.
The DeFi ecosystem on zkSync Era centers around a handful of native protocols.
| Project | Type | TVL ($100M) | Token |
|---|---|---|---|
| Maverick | DEX | 4.5 | MAV |
| Aave V3 | Lending | 3.2 | AAVE |
| SyncSwap | DEX | 2.8 | — |
| Mute | DEX | 1.5 | MUTE |
| Holdstation | Perpetuals | 1.2 | HOLD |
| ZeroLend | Lending | 1.0 | ZERO |
| Rollup Finance | Perpetuals | 0.8 | RUP |
| Velocore | DEX | 0.5 | VC |
zkSync Era's ecosystem is still at an earlier stage compared to Arbitrum or Base. Maverick is the highest-TVL DEX on zkSync, using a Dynamic Distribution Market Making (DDM) algorithm that, in certain scenarios, achieves 2-5x better capital efficiency than Uniswap V3.
zkSync Era faces several key challenges. The first is airdrop user retention. After the June 2024 airdrop, a large wave of airdrop farmers sold off immediately, and daily active on-chain addresses dropped from 800,000 to 120,000, with TVL falling from a peak of $3.5 billion to $2.8 billion.
The second is developer friction from EVM compatibility. zkSync Era uses its own zkEVM bytecode, and some Solidity libraries (such as contracts using the SELFDESTRUCT opcode) need to be modified before they can be deployed. That creates adaptation costs for projects migrating over from Arbitrum or Optimism.
The third is centralization of proof-generation hardware. Currently, all of zkSync Era's Prover nodes are operated by Matter Labs, making it a de facto point of centralization. Decentralizing the Prover network is a key item on the 2026-2027 roadmap.
zkSync Era's official bridge is maintained through contracts run by Matter Labs. Below is a comparison of the leading bridges.
| Bridge | Mainnet to zkSync | zkSync to Mainnet | Fee |
|---|---|---|---|
| Official Bridge | 10 minutes | 24 hours | 0.1% |
| Across | 5 minutes | 15 minutes | 0.1-0.3% |
| Stargate | 5 minutes | 10 minutes | 0.05-0.2% |
| Orbiter | 3 minutes | 5 minutes | 0.05% |
Third-party bridges have a clear speed advantage. But keep in mind: third-party bridges rely on liquidity pools or multisig mechanisms, and their security model has nothing to do with ZK proofs — they carry their own risk of the bridge itself being hacked. For large amounts (over $100,000), it's best to use the official bridge.
Q: Why can zkSync Era withdraw faster than Arbitrum?
Because ZK Rollups rely on cryptographic proofs rather than an economic challenge period. By the time a batch of transactions goes on-chain, the mainnet has already mathematically verified its correctness, so there's no need to wait 7 days. Arbitrum's Optimistic model has to wait the full 7 days to confirm nobody has challenged the batch before allowing a withdrawal.
Q: Is zkSync's ZK proof really impossible to cheat?
ZK-SNARK proofs are mathematically uncheatable — but only if zkSync's circuit implementation has no bugs and the Trusted Setup has no backdoor. In 2023, zkSync held a Powers of Tau ceremony to help ensure the security of its Trusted Setup.
Q: What's used to pay gas on zkSync Era?
ETH. zkSync Era hasn't swapped its gas token for ZK — all transaction fees are paid in ETH. This is consistent with how Base and Optimism handle it.
Q: Is the ZK token worth holding long term?
It's under pressure in the short term. Investor unlocks, team unlocks, and ecosystem fund releases are stacking up, and that sell pressure will likely continue through 2025-2027. Long term, the ZK token's value will hinge on how big the ZK Stack ecosystem gets and how the sequencer's net revenue ends up being distributed.
Q: What's being done about zkSync Era's Prover centralization?
Matter Labs plans to roll out a decentralized Prover network in 2026. Anyone will be able to stake ZK tokens to become a Prover node and earn ZK token rewards based on the number of proofs they generate.
Q: Which is better, zkSync Era or Polygon zkEVM?
zkSync Era leads in user base and TVL, while Polygon zkEVM has stronger EVM compatibility (closer to full equivalence). Developers migrating contracts from the mainnet will find Polygon zkEVM more convenient, while everyday users will generally find better liquidity on zkSync Era.
Q: How's the NFT ecosystem on zkSync?
Relatively thin. The main NFT marketplaces on zkSync are Element Market and tofuNFT. Liquidity is nowhere near what you'll find on Blur (mainnet) or Magic Eden (Solana).
Q: How do you judge a fair valuation for the ZK token?
Three key metrics matter: annualized sequencer net revenue, ZK Stack ecosystem adoption, and the actual circulating share once unlocks are accounted for. The ZK token's current FDV is around $3 billion, but annualized sequencer net revenue is only a few million dollars, putting its implied P/E on the high side.
The ZK token carries sell-pressure risk from ongoing unlocks, with 2025-2027 being the key unlock window. zkSync Era's Prover and sequencer remain centralized today, still some distance from the goal of decentralization. Like other AI-narrative projects, ZK-related projects also carry valuation premium risk. This article is compiled from publicly available data and does not constitute investment advice.
