Fee Tiers on Uniswap v3
Uniswap v3 supports four fee tiers to match different volatility profiles:
Lower tiers suit stable pairs, while higher tiers accommodate volatile assets.
Quick Take
- Uniswap v3 now runs on ZKsync Era, cutting gas fees by ~90% while keeping full v3 functionality.
- Concentrated liquidity and NFT‑based LP positions stay intact, giving up to 4,000× capital efficiency.
- Four fee tiers (0.01%, 0.05%, 0.3%, 1%) let traders match risk and volatility.
- TVL on ZKsync is modest (~$450k) - expect higher slippage on large trades.
- Security comes from zero‑knowledge proofs, offering stronger guarantees than optimistic rollups.
What is Uniswap v3 on ZKsync?
When you hear Uniswap v3 ZKsync review is the integration of the leading AMM protocol with Matter Labs' ZKsync Era zero‑knowledge roll‑up. In plain terms, it means the same smart‑contract suite that powers billions of dollars of trades on Ethereum now lives on a Layer2 that batches transactions off‑chain and proves them with succinct cryptographic proofs. The result? Faster block times, sub‑second finality, and a drastic drop in gas costs.
ZKsync Era is an Ethereum Layer2 scaling solution that uses zero‑knowledge proofs to secure off‑chain computation while inheriting Ethereum's security guarantees. Unlike optimistic rollups (Arbitrum, Optimism), ZKsync validates each batch before it hits the main chain, eliminating the need for a fraud‑proof window.
Uniswap v3 itself launched in May2021, bringing the revolutionary Concentrated Liquidity is a model where liquidity providers allocate capital to a narrow price range instead of the entire curve. That design lets LPs earn fees on a fraction of the curve they actually care about, dramatically boosting capital efficiency.
Core Features That Carry Over to ZKsync
- Fee tiers: 0.01%, 0.05%, 0.3% and 1% - each tier matches a different volatility profile.
- LP NFTs are ERC‑721 tokens that represent a unique liquidity position, encoding price range, amount and fee tier. The NFT format stays the same on ZKsync.
- TWAP Oracles are time‑weighted average price feeds that require only a single on‑chain call, cutting costs for downstream protocols.
- Full support for limit orders, price range adjustments, and fee collection-all executed with ZKsync's cheap gas.
Performance & Cost Benefits
On Ethereum mainnet a typical swap of $1,000 in USDC/ETH can cost $10‑$15 in gas. On ZKsync Era the same trade usually settles for $0.80‑$1.20, a roughly 90% reduction. Confirmation times drop from 15‑30seconds to under 1second, meaning you can react to price moves much faster.
That efficiency comes with a trade‑off: the liquidity pools on ZKsync are smaller. ChainBroker reports total value locked (TVL) of about $450k, a drop‑in‑the‑bucket compared with the $1.2B TVL on Arbitrum or the $2.5B on Ethereum. For small‑to‑medium swaps the impact is negligible, but a $50k trade could see noticeably higher slippage than on a deeper pool.
How It Stacks Up Against Other L2 DEX Deployments
| Network | Security Model | Avg. Gas per Swap (USD) | TVL (USD) | Typical Slippage for $10k Trade |
|---|---|---|---|---|
| ZKsync Era | Zero‑knowledge proofs | ~0.90 | 450k | 0.30% |
| Arbitrum | Optimistic roll‑up | ~1.20 | 1.2B | 0.12% |
| Optimism | Optimistic roll‑up | ~1.10 | 800k | 0.15% |
| Polygon | Side‑chain (Plasma) | ~0.65 | 600k | 0.18% |
Zero‑knowledge proof security gives ZKsync an edge over optimistic roll‑ups, but the smaller ecosystem means fewer pools and lower depth. Polygon still beats ZKsync on raw gas cost, yet it relies on a different security assumption.
On‑Boarding: From Wallet to First Swap
- Install a ZKsync‑compatible wallet (e.g., MetaMask with custom RPC, Argent X, or zkSync Wallet).
- Visit app.uniswap.org, click the network selector, and pick ZKsync Era.
- Bridge assets from Ethereum mainnet to ZKsync via the official zkSync Bridge. Expect a 5‑minute wait for the proof to settle.
- Choose a pool, select the fee tier that matches the token volatility, and set your price range if you’re providing liquidity.
- Confirm the transaction - the UI will show an estimated gas fee in USD before you sign.
The flow mirrors the Ethereum version, so existing Uniswap users feel right at home. The extra bridge step is the only friction point; however, many wallets now offer one‑click bridge widgets that hide the complexity.
Pros & Cons - A Straightforward Summary
- Pros
- ~90% gas savings vs. Ethereum mainnet.
- Sub‑second finality improves trading experience.
- Zero‑knowledge security eliminates fraud‑proof windows.
- All v3 features (concentrated liquidity, NFT positions, four fee tiers) are fully supported.
- Community incentives (Layer3 quests, CUBE rewards) boost early‑adopter engagement.
- Cons
- Liquidity depth is low - larger trades can suffer slippage.
- Bridge step adds a delay and requires a small amount of mainnet ETH for fees.
- NFT‑based LP positions are less composable with other DeFi protocols.
- Documentation is split between Uniswap and ZKsync, making onboarding a bit messy for beginners.
Future Outlook: Uniswap v4 and the ZKsync Ecosystem
Uniswap Labs has announced Uniswap v4 is a hook‑based upgrade that will let developers embed custom logic into pools, potentially lowering fees further. While v4 is still in testnet, the ZKsync team has signaled intent to be a first‑class host, meaning future versions could benefit from even tighter integration.
ZKsync’s roadmap includes “zkPortals,” which aim to bring cross‑chain composability without sacrificing proof‑based security. If those land, we could see a surge of liquidity moving from Ethereum to Layer2, narrowing the TVL gap noted earlier.
For now, the key to ZKsync’s success hinges on community builders like Oku Trade is a front‑end DEX built on Uniswap v3 contracts on ZKsync, offering advanced charts and limit orders adding richer UI layers. As more tools appear, the friction of bridging and managing NFT positions should drop, making ZKsync a go‑to playground for DeFi power users.
Bottom Line
If you value cheap swaps and lightning‑fast confirmation over massive pool depth, Uniswap v3 on ZKsync Era is a solid choice. The protocol retains every advantage of v3-concentrated liquidity, flexible fee tiers, NFT‑based LPs-while slashing gas costs dramatically. Expect higher slippage on very large trades until the ecosystem grows, but the security guarantees and emerging tooling make it a promising foothold in the Layer2 future.
Frequently Asked Questions
Do I need to hold ETH to use Uniswap v3 on ZKsync?
You only need ETH for the initial bridge transaction. Once your assets are on ZKsync, you can pay fees with the native token (ETH on ZKsync) or supported stablecoins, depending on the wallet.
How does gas cost on ZKsync compare to Polygon?
Polygon typically offers the cheapest per‑transaction cost (~$0.60), but ZKsync’s zero‑knowledge security is stronger than Polygon’s side‑chain model. The difference is modest-about $0.30 per swap.
Can I provide liquidity using the same UI as on Ethereum?
Yes. The Uniswap web app automatically switches to the ZKsync version when you select the network. All settings-price range, fee tier, liquidity amount-work exactly the same.
What security guarantees does ZKsync provide?
ZKsync uses zk‑SNARK proofs that are validated on Ethereum before finality. This means every batch is mathematically proven correct, eliminating the trust‑less wait period required by optimistic roll‑ups.
Will Uniswap v4 be available on ZKsync?
The roadmap indicates a ZKsync‑first rollout for v4 hooks, but the exact timeline is still pending. Keep an eye on Uniswap Labs and zkSync announcements for the latest updates.

September 16, 2025 AT 22:14The ZK‑rollup architecture leverages succinct non‑interactive arguments of knowledge to compress transaction calldata, thereby achieving asymptotic gas reductions on the order of O(1) per batch. When mapping Uniswap v3’s concentrated liquidity positions onto the ZKsync state tree, the slot‑based representation remains invariant, preserving the quadratic fee accrual mechanism. Moreover, the immutable pool contract interface adheres to the ERC‑4626 standard, facilitating composability with yield‑optimizing vaults without additional wrapper overhead. From a protocol‑level perspective, the execution engine validates proofs via a deterministic verifier, which eliminates the need for on‑chain state witnesses that traditionally inflate gas. Liquidity providers can therefore re‑balance their price range allocations with a marginal delta, as the underlying tick bitmap is updated through a succinct state transition function. The fee tier bifurcation continues to serve risk‑adjusted capital allocation, with the 0.01% tier optimizing for stablecoin pairs and the 1.00% tier compensating for high‑volatility assets. On ZKsync Era, the effective gas price is priced in ETH equivalents but denominated in USD via the on‑chain oracle, aligning miner incentives with market dynamics. The integration also introduces a secondary settlement layer that resolves intra‑batch arbitrage opportunities through a deterministic ordering algorithm. Because the rollup aggregates signatures, the signature verification cost amortizes across dozens of swaps, thereby further compressing per‑transaction gas overhead. From a risk management standpoint, the proof‑generated state root ensures that any state divergence is cryptographically impossible without breaching the SNARK soundness bound. Developers can query the pool’s liquidity distribution via a GraphQL endpoint that mirrors the on‑chain slot layout, enabling real‑time analytics without additional RPC calls. The gas cost calculator embedded in the UI abstracts the underlying EVM bytecode cost model, presenting end‑users with a USD estimate that incorporates both base fee and priority fee components. Importantly, the cross‑chain bridge to Ethereum preserves the token provenance, allowing LPs to migrate positions without incurring double‑spend risks. The slippage tolerance parameters retain their original linear interpolation behavior, ensuring that price impact calculations remain deterministic. Overall, the synergy between Uniswap v3’s modular architecture and ZKsync’s succinct proof system yields a net efficiency gain that is quantifiable both in gas units and in user‑perceived latency. Consequently, the protocol’s capital efficiency curve shifts upward, offering a more attractive risk‑adjusted return profile for liquidity providers and traders alike.

Mark Camden
September 16, 2025 AT 22:30From an ethical standpoint, the reduction of transaction fees aligns with the broader principle of financial inclusivity. However, the platform must also prioritize transparency regarding the underlying zk‑proof assumptions. Users deserve clear disclosures about any potential centralization vectors introduced by the rollup operators. In sum, cost efficiency should not eclipse governance accountability.
Evie View
September 16, 2025 AT 22:39Your naive optimism ignores the systemic risk that zk‑rollups can introduce under adverse load. The hidden latency spikes could erode trader confidence faster than any fee savings. Stop glossing over the security trade‑offs.
Kate Roberge
September 16, 2025 AT 22:44Honestly, the community’s hype feels overblown; not every upgrade is a game‑changer. The core mechanics stay the same, so expect incremental tweaks, not a revolution. Keep your expectations grounded.

September 16, 2025 AT 22:50How does the proof verification affect finality times? Are liquidity providers compensated for additional proof‑validation costs? Clarify the impact on APY calculations.
Jason Brittin
September 16, 2025 AT 22:59Wow, another layer of magic, because we totally needed more abstractions 😂. Guess we’re all set for infinite scalability.
Amie Wilensky
September 16, 2025 AT 23:09The integration, while technically impressive, raises several practical concerns, notably the user onboarding experience, the documentation clarity, and the real‑time fee transparency. Moreover, the reliance on zk‑proofs, which are computationally intensive, could bottleneck transaction throughput during peak periods. Additionally, the UI’s gas calculator, although convenient, may oversimplify the underlying fee dynamics, leading to potential misinterpretations. Finally, the ecosystem must monitor for any emergent centralization risks linked to the rollup validator set.
MD Razu
September 16, 2025 AT 23:15Let me unpack why the purported gas savings are, in my view, a classic case of marketing smoke and mirrors. First, the baseline gas cost on Ethereum is already volatile, fluctuating with network congestion, so a static comparison understates the dynamic nature of fees. Second, ZKsync’s batching mechanism, while reducing per‑transaction cost, introduces latency that can be detrimental for high‑frequency traders seeking immediate execution. Third, the liquidity provision model remains unchanged, meaning LPs still bear the same impermanent loss risk without any compensatory yield boost. Fourth, the additional complexity of proof generation could increase the operational overhead for developers, potentially leading to higher maintenance costs. Fifth, the user interface’s abstraction may hide critical parameters such as proof verification time, which can affect the overall trade execution experience. Sixth, the ecosystem’s reliance on a limited set of validators introduces a subtle centralization vector that could be exploited in adverse scenarios. In conclusion, the narrative of “cheaper swaps” must be weighed against these latent trade‑offs before declaring the integration an unequivocal success.
Charles Banks Jr.
September 16, 2025 AT 23:24Sure, cheaper gas sounds great on paper, but you still need to understand the fee tier math to avoid nasty surprises. The UI tweaks don’t magically fix bad pool choices. Plus, the rollup adds another layer of complexity that most retail users will never grasp. Bottom line: savings = only part of the puzzle.
Ben Dwyer
September 16, 2025 AT 23:29The step toward ZKsync is encouraging for the ecosystem, as it demonstrates commitment to scaling. Keep experimenting with the new fee calculator to fine‑tune your strategies.
Lindsay Miller
September 16, 2025 AT 23:35I get that the lower fees can feel like a breath of fresh air. At the same time, it’s okay to be cautious about new tech. Take your time to test small trades first.

September 17, 2025 AT 00:00Everyone should share their experiences so we can all learn together. The rollup could be a big step forward if the community stays supportive. dont forget to report any bugs you find.

September 17, 2025 AT 00:09Some folks think the rollup is just a front for hidden data collection. I prefer to stay skeptical until the code is fully open.
