Uniswap is the largest decentralized exchange (DEX) in the world, having processed over $3 trillion in cumulative trading volume since launching in 2018. In 2026, it commands 50-65% of all weekly DEX volume, operates across 13+ blockchain networks, and has undergone a transformative governance overhaul called UNIfication that introduced protocol fee collection and UNI token burns. In this comprehensive Uniswap review for 2026, we cover fees, supported chains, v4 Hooks, Unichain L2, liquidity provision, security, and the UNI token -- giving you everything you need to decide whether Uniswap is the right DEX for your trading needs.

What Is Uniswap?
Uniswap is a non-custodial, decentralized exchange protocol built primarily on the Ethereum blockchain. It is the pioneering Automated Market Maker (AMM) that replaced traditional order books with liquidity pools, allowing anyone to swap tokens directly from their wallet without creating an account, verifying their identity, or handing over custody of their funds.
Founded by Hayden Adams in 2018, Uniswap has evolved through four major protocol versions -- each introducing fundamental improvements to capital efficiency, customization, and gas optimization. The protocol is governed by UNI token holders through on-chain governance proposals, and its smart contracts are open-source, non-upgradeable, and extensively audited. With approximately $4.5 billion in total value locked and deployment across 13+ blockchain networks, Uniswap remains the dominant force in decentralized finance.
Unlike centralized exchanges such as Coinbase or Binance, Uniswap operates without intermediaries. You connect your wallet, select your tokens, and confirm the swap -- the underlying smart contracts handle everything else, including price discovery and trade execution through liquidity pools.
Key Features of Uniswap in 2026
Uniswap v4: Hooks, Singleton Architecture, and Gas Savings
Uniswap v4 is the most significant upgrade in the protocol's history. Launched on January 31, 2025, it has already processed over $110 billion in cumulative trading volume and hosts over 2,500 custom liquidity pools. The three headline innovations are:
- Hooks: Modular smart contract plugins that let developers customize pool behavior at specific points during a transaction lifecycle -- before or after swaps, and before or after liquidity position changes. Hooks enable limit orders, dynamic fees, custom oracles, on-chain TWAP (time-weighted average price) orders, auto-compounding strategies, and MEV protection. Developers create an average of approximately 100 new Hooks daily, building an expanding ecosystem of custom DeFi applications on top of Uniswap.
- Singleton Architecture: All pools now live within a single smart contract, replacing the one-contract-per-pool model of v3. This reduces pool creation gas costs by 99% and significantly lowers multi-hop swap gas costs, since tokens no longer need to be transferred between separate contracts for each hop.
- Flash Accounting: Tokens are only transferred at the end of a transaction rather than at each intermediate step, further reducing gas consumption and enabling more complex multi-step operations within a single transaction.
Uniswap v4 also introduced native ETH support, eliminating the need to wrap ETH into WETH before trading. This saves users roughly 15% on gas fees for ETH-pair trades. As of early 2026, v4 handles approximately 30% of all Uniswap trades, with v3 still processing around 60% and v2 handling the remainder.
Unichain: Uniswap's Dedicated Layer 2
Unichain is Uniswap's own Layer 2 rollup network, purpose-built for DeFi trading. Launched in 2024 and now processing nearly 50% of all v4 transaction volume, Unichain offers faster finality, significantly lower fees than Ethereum mainnet, and an infrastructure stack optimized specifically for decentralized exchange activity.
Under the UNIfication proposal approved in December 2025, Unichain sequencer fees (after L1 data costs and the 15% allocation to Optimism's Superchain) are directed into the UNI burn mechanism. This means that as Unichain adoption grows, it directly contributes to reducing the circulating supply of UNI tokens. Unichain currently generates approximately $7.5 million in annualized sequencer fees and processes around $100 billion in annualized DEX volume.
UNIfication: Protocol Fees and UNI Burns
The UNIfication proposal, jointly submitted by Uniswap Labs and the Uniswap Foundation in November 2025 and overwhelmingly approved by governance in December 2025, represents the most consequential economic change in Uniswap's history. The proposal established a comprehensive model for how the Uniswap ecosystem operates, where protocol usage directly drives UNI token burns. Key components include:
- Protocol Fee Activation: The long-discussed fee switch has been officially turned on. For v2 pools, protocol fees are set at 0.05% (with LP fees reduced from 0.30% to 0.25%). For v3 pools, protocol fees are set at 1/4 of LP fees for the 0.01% and 0.05% tiers, and 1/6 of LP fees for the 0.30% and 1.00% tiers.
- UNI Burn Mechanism: All protocol fees flow into an immutable on-chain contract called TokenJar. Fees can only be withdrawn from TokenJar when UNI is burned in a companion smart contract called Firepit. This creates a permanent, programmatic link between protocol revenue and UNI supply reduction.
- Treasury Burn: 100 million UNI tokens (worth over $590 million at the time) were burned from the treasury -- representing the approximate amount that would have been burned if fees had been active since Uniswap's creation in 2018.
- Protocol Fee Discount Auctions (PFDA): A new mechanism that auctions the right to swap without paying protocol fees for a short time window. Winning bids go to the UNI burn, effectively internalizing MEV (Maximal Extractable Value) that would otherwise flow to searchers or validators. Early analysis suggests PFDA could significantly increase protocol revenue beyond standard fee collection.
- Aggregator Hooks: Uniswap v4 is being transformed into an on-chain aggregator that can collect fees on external liquidity, expanding revenue sources beyond Uniswap's own pools.
- Interface Fee Removal: Uniswap Labs contractually committed to removing all interface, wallet, and API fees (previously 0.25%), aligning Labs entirely with protocol success rather than front-end revenue.
Cross-Chain Swaps via UniswapX
Through its integration with Across Protocol and UniswapX, users can perform cross-chain swaps across nine EVM-compatible networks directly from the Uniswap interface. UniswapX uses a Dutch auction mechanism and third-party fillers to find optimal prices across on-chain and off-chain liquidity sources. Fillers submit orders on-chain and cover gas costs, offering users gas-free swapping on supported routes.
Mobile Wallet and Self-Custody
The Uniswap Wallet (available on iOS and Android) supports ERC-20 tokens across all 13+ supported networks. It functions as both a self-custody wallet and a full trading interface, allowing users to swap tokens, manage NFTs, track portfolios, and receive push notifications -- all without giving up control of their private keys. Users can also purchase crypto directly within the app using a debit card through third-party payment providers.
Uniswap Fees Explained
Uniswap's fee structure in 2026 has four components: liquidity provider fees, protocol fees (newly activated), network gas fees, and interface fees (now zero). This is the most significant change since Uniswap launched, as the protocol now actively collects revenue for the first time.
| Fee Type | Amount | Who Receives It |
|---|---|---|
| LP Fee (v2) | 0.25% (reduced from 0.30% after fee switch) | Liquidity providers |
| LP Fee (v3) | 0.01%, 0.05%, 0.30%, or 1.00% (fixed tiers) | Liquidity providers |
| LP Fee (v4) | 0% - 100% (fully flexible, set per pool via Hooks) | Liquidity providers |
| Protocol Fee (v2) | 0.05% | UNI burn mechanism (TokenJar/Firepit) |
| Protocol Fee (v3) | 1/4 of LP fee (0.01%, 0.05% tiers); 1/6 of LP fee (0.30%, 1.00% tiers) | UNI burn mechanism |
| Interface Fee | 0% (removed December 2025) | N/A (Uniswap Labs no longer charges) |
| Network Gas Fee | Variable (chain and congestion dependent) | Network validators/sequencers |
The most common fee tier for major token pairs (ETH/USDC, ETH/WBTC) is 0.30% on v3, with the effective total cost to traders being the LP fee plus the protocol fee plus network gas. For stablecoin pairs, the 0.01% and 0.05% tiers are standard. On Layer 2 networks like Arbitrum, Base, and Unichain, gas fees are typically under $0.50, making small trades far more cost-effective than on Ethereum mainnet where gas can exceed $10 during congestion.
Importantly, the protocol fee is not an additional charge on top of what traders pay. For v3, the protocol fee is carved out of the existing LP fee -- so if a pool charges 0.30% and the protocol takes 1/6, liquidity providers receive 0.25% and the protocol receives 0.05%. For v2, however, the total fee increased slightly from 0.30% to 0.30% (0.25% LP + 0.05% protocol).
Supported Chains and Tokens
Uniswap is deployed across 13+ blockchain networks as of 2026, making it one of the most widely available DEX protocols:
| Chain | Type | Versions Available | Typical Gas Fee |
|---|---|---|---|
| Ethereum | Layer 1 | v2, v3, v4 | $1 - $30+ |
| Arbitrum | Layer 2 (Optimistic Rollup) | v2, v3, v4 | $0.05 - $0.50 |
| Optimism | Layer 2 (Optimistic Rollup) | v2, v3, v4 | $0.05 - $0.40 |
| Base | Layer 2 (Optimistic Rollup) | v2, v3, v4 | $0.01 - $0.20 |
| Polygon | Sidechain | v2, v3, v4 | $0.01 - $0.10 |
| BNB Smart Chain | Layer 1 | v2, v3, v4 | $0.05 - $0.30 |
| Avalanche | Layer 1 | v2, v3, v4 | $0.05 - $0.50 |
| Celo | Layer 1 | v3 | Under $0.01 |
| Blast | Layer 2 | v3, v4 | $0.01 - $0.10 |
| ZKsync | Layer 2 (ZK Rollup) | v3 | $0.05 - $0.20 |
| Zora | Layer 2 | v3 | Under $0.01 |
| World Chain | Layer 2 | v3, v4 | $0.01 - $0.10 |
| Unichain | Layer 2 (Uniswap's Own) | v4 | Under $0.10 |
Approximately 67.5% of daily volume now occurs on Layer 2 networks, with 72% of TVL sitting on L2 chains -- reflecting the industry-wide shift toward faster, cheaper transactions. Any ERC-20 token can be listed permissionlessly on Uniswap, resulting in tens of thousands of available trading pairs. However, because tokens are not vetted, users must exercise caution and verify contract addresses before trading unfamiliar tokens to avoid scam tokens and honeypots.
How to Provide Liquidity on Uniswap
Providing liquidity on Uniswap is one of the primary ways to earn passive income in DeFi. Liquidity providers (LPs) deposit token pairs into pools and earn a proportional share of swap fees generated by that pool. Here is how the process works across different versions:
Concentrated Liquidity (v3 and v4)
Uniswap v3 introduced concentrated liquidity, which allows LPs to allocate capital within specific price ranges rather than across the entire price curve. This dramatically improves capital efficiency -- an LP providing liquidity in a narrow range earns the same fees as one providing across the full range with significantly less capital.
For example, if you believe ETH will trade between $2,800 and $3,200, you can concentrate your liquidity in that range. If the price stays within your range, you earn all the swap fees from trades in that band. If the price moves outside your range, your position becomes inactive and earns no fees until the price returns.
v4 Hooks for Advanced LP Strategies
Uniswap v4 takes this further with Hooks that enable auto-rebalancing positions, dynamic fee adjustment based on volatility, and auto-compounding of earned fees. Projects like Bunni, Silo, and EulerSwap have built sophisticated LP management tools on top of v4 Hooks, allowing LPs to deploy strategies that were previously only available to sophisticated DeFi protocols.
Impermanent Loss: The Key Risk
The primary risk for liquidity providers is impermanent loss -- the difference between holding tokens in a pool versus simply holding them in your wallet. When the relative price of the two tokens in your pair changes significantly, you end up with more of the lower-value token and less of the higher-value token. For volatile pairs, impermanent loss can exceed the fees earned. Stablecoin pairs (USDC/USDT, DAI/USDC) carry minimal impermanent loss risk, making them popular choices for conservative LPs.
Security and Trust
Uniswap is one of the most battle-tested protocols in all of DeFi, having secured billions of dollars in user funds since 2018 without a core smart contract exploit. Its security profile includes:
- Non-upgradeable smart contracts: Once deployed, the protocol code cannot be changed by anyone, including the development team. This immutability eliminates the risk of malicious upgrades but means bugs cannot be patched -- they must be addressed in new versions.
- Open-source code: Fully auditable by anyone. Each protocol version has undergone multiple professional security audits from firms including Trail of Bits, OpenZeppelin, and ABDK.
- Non-custodial architecture: Users retain full control of their funds at all times. Uniswap never holds your tokens -- trades execute directly between your wallet and the pool's smart contract.
- No KYC requirements: Trading is permissionless and does not require identity verification, though certain tokens may be restricted on the front-end interface due to regulatory considerations.
- Bug bounty program: Uniswap maintains one of the largest bug bounty programs in DeFi, with rewards up to $15.5 million for critical vulnerabilities, incentivizing responsible disclosure from security researchers worldwide.
- DUNI governance structure: In 2025, Uniswap governance adopted DUNI, a Wyoming DUNA (Decentralized Unincorporated Nonprofit Association), providing a legal framework for the DAO's operations and adding a layer of regulatory clarity.
The primary risks when using Uniswap are interacting with malicious or fake tokens (always verify contract addresses), impermanent loss for liquidity providers, high gas fees on Ethereum mainnet during congestion, and the absence of customer support to reverse erroneous transactions. Unlike centralized exchanges, there is no entity that can freeze or recover funds sent to the wrong address.
UNI Token and Governance
The UNI token is Uniswap's governance token, giving holders the power to vote on protocol upgrades, fee parameters, treasury allocations, and grant programs. Following the UNIfication proposal, UNI has evolved from a pure governance token into one with direct economic utility through the burn mechanism.
UNI Tokenomics After UNIfication
| Metric | Value |
|---|---|
| Original Total Supply | 1 billion UNI |
| Treasury Burn | 100 million UNI burned (December 2025) |
| Ongoing Burns | Continuous via protocol fees, Unichain sequencer fees, and PFDA |
| Governance | On-chain voting via DUNI (Wyoming DUNA) |
| All-Time High | $44.92 |
| All-Time Low | $1.03 |
The burn mechanism creates a deflationary pressure on UNI supply that scales with protocol usage. As Uniswap's trading volume grows, more fees are collected, more UNI is burned, and the circulating supply decreases. This is a fundamentally different economic model from the previous years where UNI was solely a governance token with no direct value accrual from protocol activity.
Governance Activity
Uniswap governance approved the "Uniswap Unleashed" program in 2025 -- a $95.4 million grants pool and $25.1 million operational budget managed by the Uniswap Foundation. Governance participation has increased since UNIfication, as token holders now have a direct financial stake in protocol decisions. Key governance powers include adjusting protocol fee parameters (which skip the RFC process and move straight to Snapshot followed by an on-chain vote for efficiency), treasury management, and approving ecosystem grants.
User Experience
Uniswap's interface is widely regarded as the gold standard for DEX design. The web app at app.uniswap.org provides a clean, intuitive experience that works for beginners and advanced users alike:
- One-click token swaps with automatic best-price routing across v2, v3, and v4 pools plus UniswapX off-chain liquidity
- Clear display of estimated output, price impact, minimum received, and network fees before confirmation
- Automatic wallet detection for MetaMask, Coinbase Wallet, WalletConnect, Rabby, and dozens of other wallets
- Limit orders powered by v4 Hooks -- set a target price and the order executes automatically when conditions are met
- Cross-chain swaps across nine networks via UniswapX integration
- NFT marketplace aggregation for browsing and purchasing NFTs across major marketplaces
- Network switching with one click to trade on any supported chain
The mobile app mirrors the web experience and adds portfolio tracking, push notifications, biometric authentication, and built-in wallet management. For beginners, the process is straightforward: select your input and output tokens, enter an amount, review the quote, and confirm the swap in your wallet. Advanced users can access concentrated liquidity position management, custom fee tiers, analytics dashboards, and Hooks-powered pool creation.

| Best For | Spot swaps, ERC-20 trading, LPs | Multi-chain DeFi users | BNB Chain traders | Perpetual/leverage trading | Stablecoin swaps |
Uniswap leads overwhelmingly in spot trading volume and total liquidity. For stablecoin-to-stablecoin swaps, Curve Finance often provides lower slippage due to its specialized bonding curve. Traders seeking perpetual contracts with leverage should consider dYdX or PancakeSwap. For BNB Chain-native tokens, PancakeSwap typically offers deeper liquidity and lower fees. SushiSwap provides broader multi-chain coverage but with significantly less liquidity than Uniswap on every chain where both operate.
Who Should Use Uniswap?
Uniswap is best suited for:
- DeFi traders who want non-custodial, permissionless access to thousands of ERC-20 tokens without KYC
- Privacy-conscious users who prefer trading without identity verification requirements
- Liquidity providers seeking to earn swap fees through concentrated liquidity positions on the most liquid DEX
- DeFi developers building custom applications using v4 Hooks -- from custom AMM curves to on-chain limit orders
- Multi-chain users who want a single, consistent interface across 13+ networks
- Long-term DeFi participants who want exposure to UNI's new burn-driven tokenomics
Uniswap may not be the best choice for complete beginners unfamiliar with self-custody wallets, users who need direct fiat on/off-ramps, or traders seeking leveraged perpetual contracts. If you are new to crypto and want a simpler onboarding experience, a centralized exchange may be a better starting point before graduating to DeFi.
How to Get Started with Uniswap
- Set up a wallet: Download MetaMask, Coinbase Wallet, or the Uniswap Wallet app. Securely store your recovery phrase offline -- losing it means losing access to your funds permanently.
- Fund your wallet: Transfer ETH or tokens from a centralized exchange like Coinbase or Kraken, or purchase directly through the Uniswap Wallet using a debit card via third-party providers.
- Choose your network: For lower fees, bridge your assets to Arbitrum, Base, or Unichain before swapping. The Uniswap interface includes built-in cross-chain swap functionality via UniswapX.
- Visit the app: Go to app.uniswap.org and connect your wallet.
- Select your tokens: Choose the input and output tokens and enter the amount you want to swap.
- Review and confirm: Check the estimated output, price impact, minimum received, and gas fee. Confirm the transaction in your wallet.
For the lowest-cost experience, we recommend trading on Unichain, Base, or Arbitrum where gas fees are typically under $0.50 per transaction. Ethereum mainnet remains the deepest liquidity venue for large trades where minimizing slippage matters more than gas costs.
Final Verdict
Uniswap is the undisputed leader in decentralized exchange trading in 2026, and the gap between it and its competitors has only widened. The launch of v4 Hooks and singleton architecture established Uniswap as the most technically advanced DEX, while UNIfication transformed it from a fee-free public good into a protocol with genuine economic alignment between usage and token value. The removal of interface fees, expansion to 13+ chains, the growth of Unichain as a dedicated DeFi Layer 2, and the introduction of the UNI burn mechanism make Uniswap more compelling than ever for both traders and token holders.
While risks like impermanent loss, unvetted tokens, and Ethereum mainnet gas fees persist, Uniswap's eight-year track record of security, continuous innovation, and active community governance make it the benchmark against which all other DEXs are measured. For anyone trading tokens across the Ethereum ecosystem and its Layer 2 networks, Uniswap is an essential tool in 2026.
Frequently Asked Questions
Is Uniswap safe to use in 2026?
Uniswap is one of the safest decentralized exchanges available, with over eight years of operation and no core smart contract exploits. Its contracts are non-upgradeable, open-source, and audited by multiple leading security firms. As a non-custodial protocol, your funds stay in your own wallet at all times. The main risks are interacting with scam tokens (always verify contract addresses), impermanent loss when providing liquidity, and user error -- since there is no customer support to reverse mistaken transactions.
What are Uniswap's fees in 2026?
Uniswap charges zero interface fees as of December 2025. Liquidity provider swap fees range from 0.01% to 1% on v3 (0.30% is most common) and are fully flexible on v4. Protocol fees are now active: 0.05% on v2, and 1/4 to 1/6 of LP fees on v3, depending on the fee tier. These protocol fees fund the UNI burn mechanism. Network gas fees vary by chain -- typically under $0.50 on Layer 2 networks like Arbitrum, Base, and Unichain, but can exceed $10 on Ethereum mainnet during congestion.
What is UNIfication and how does the UNI burn work?
UNIfication is a governance proposal approved in December 2025 that activated Uniswap's protocol fees and established a mechanism to burn UNI tokens. Protocol fees flow into a smart contract called TokenJar, and they can only be withdrawn when UNI is burned in a companion contract called Firepit. Additionally, 100 million UNI were burned from the treasury, and Unichain sequencer fees also feed the burn. This creates a deflationary model where more trading activity means more UNI is burned.
Can US citizens use Uniswap?
Yes, US citizens can use Uniswap to swap tokens, provide liquidity, and participate in governance. Uniswap does not require KYC verification. However, certain tokens may be restricted on the front-end interface due to regulatory considerations, though they remain accessible through the underlying smart contracts or alternative front-ends.
What is Uniswap v4 and what are Hooks?
Uniswap v4 is the latest version of the protocol, launched on January 31, 2025. Hooks are modular smart contract plugins that allow developers to customize pool behavior at specific points in a transaction's lifecycle -- including before and after swaps, and before and after liquidity changes. This enables limit orders, dynamic fees, custom oracles, auto-compounding, and MEV protection. Over 2,500 custom pools have been created using Hooks, with approximately 100 new Hooks being created daily.
How does Uniswap compare to centralized exchanges like Coinbase?
Uniswap is decentralized and non-custodial, meaning you control your own funds and trade without identity verification. Coinbase is centralized, requires full KYC, but offers fiat deposits and withdrawals, insured custody, customer support, and a simpler onboarding experience. Uniswap provides access to far more tokens (any ERC-20 can be listed permissionlessly) and charges lower fees since December 2025, but it lacks fiat on/off-ramps and has no support team to help with issues.
What chains does Uniswap support?
Uniswap is deployed on 13+ networks in 2026: Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Smart Chain, Avalanche, Celo, Blast, ZKsync, Zora, World Chain, and Unichain (Uniswap's own Layer 2). Approximately 67.5% of daily trading volume and 72% of TVL are on Layer 2 networks, reflecting the shift toward lower-cost, faster transactions.
Can I earn passive income on Uniswap?
Yes, you can earn passive income by providing liquidity to Uniswap pools. LPs earn a share of swap fees proportional to their contribution. On v3 and v4, concentrated liquidity lets you focus capital within specific price ranges for higher capital efficiency and potentially higher returns. Be aware of impermanent loss risk, especially with volatile token pairs -- stablecoin pairs carry minimal impermanent loss and are popular among conservative LPs.
What is Unichain and why does it matter?
Unichain is Uniswap's own Layer 2 rollup network, purpose-built for DeFi trading. It processes nearly 50% of all v4 transaction volume, offers sub-$0.10 gas fees, and generates approximately $7.5 million in annualized sequencer revenue. Under UNIfication, Unichain's sequencer fees (after L1 costs and the Optimism allocation) flow into the UNI burn mechanism, directly linking Unichain's growth to UNI token value.
