Curve vs Uniswap: AMM Design, Fees, Value

For most trades, Uniswap is the better venue: it lists almost any token across more than 30 chains, holds the deepest liquidity in DeFi, and clears tens of billions of dollars in volume every month. Curve wins one specific job, moving large amounts of stablecoins and pegged assets with minimal slippage, and its CRV token has paid holders a cut of protocol revenue for five years longer than UNI has. Which one deserves your trade comes down to the pair, the order size, and whether you care about the token as much as the exchange itself.

Curve vs Uniswap at a Glance

Both protocols started on Ethereum and have since spread across its Layer 2s and beyond, but they were engineered for different problems. According to DefiLlama, Uniswap clears roughly $70 billion in 30-day trading volume across more than 30 chains as of June 2026, while Curve handles a fraction of that, concentrated almost entirely in stablecoin and pegged-asset pairs and backed by around $1.6 billion in TVL.

The table tells you what each protocol is. The sections below explain why those differences exist and when they actually matter to your execution.

How the Two AMM Designs Differ

Uniswap's original insight was the constant product formula: a pool holds two assets, their balances multiplied must always equal a constant, and the price moves along that curve with every trade. It works for any pair without needing an order book or an oracle, which is why it became the default venue for new tokens. Version 3 added concentrated liquidity in 2021, letting LPs deploy capital inside chosen price ranges instead of across the whole curve. Version 4, live since early 2025, moved every pool into a single contract and introduced a hooks system that lets developers attach custom logic, such as dynamic fees and on-chain limit orders, directly to pools. Our breakdown of Uniswap v4's hooks system covers what that unlocks in detail.

Curve's Stableswap invariant solves a different equation. It blends constant-sum pricing, which would offer perfect 1:1 swaps until a pool empties, with constant-product pricing, which never runs dry. Near the peg the curve stays almost flat, so an eight-figure USDC-to-USDT swap can execute with slippage measured in hundredths of a percent. As the pool drifts away from balance, pricing gradually reverts toward constant product to protect liquidity. Curve later extended the idea to volatile pairs with Cryptoswap pools, which use an internal price oracle to re-center liquidity around the market price automatically.

The design verdict follows from the math. Uniswap optimized for generality and lets liquidity providers and hook developers handle specialization. Curve optimized for depth wherever two assets should trade at the same price. Hooks make it technically possible to build Stableswap-style curves on Uniswap v4, but as of mid-2026 the deepest pegged-asset pools and the integrations that feed them still sit on Curve.

What Swaps Actually Cost

Fees on Curve

Curve's stable pools typically charge between 0.01% and 0.04% per swap, and half of every fee is collected by the DAO as an admin fee, per Curve's fee documentation. Cryptoswap pools use dynamic fees that scale with how far the pool sits from balance, usually landing well under 0.4%. The number that matters for large traders is total execution cost, fee plus slippage, and for size in stablecoins or liquid staking tokens that combined figure on Curve is routinely the lowest available on-chain.

Uniswap's fee tiers

Uniswap v3 pools come in four tiers: 0.01% for stable pairs, 0.05% for correlated majors, 0.30% for standard pairs, and 1% for exotic ones. On v4, hooks can adjust fees in real time based on volatility or volume. Since the protocol fee activated in December 2025, a slice of LP fees on designated pools (between one sixth and one quarter) goes to the protocol instead of liquidity providers, though the headline cost to traders is unchanged. For a typical retail-sized swap in a liquid pair, Uniswap's execution matches or beats Curve's. The gap only opens up when order size starts pushing against pool depth.

CRV vs UNI: Who Actually Gets Paid

Curve has shared revenue with token holders since August 2020. Locking CRV for up to four years converts it into veCRV, a process covered step by step in our CRV staking and locking guide, and veCRV holders collect 50% of every pool's trading fees plus most of the interest generated by crvUSD lending markets, distributed weekly. The same locked position carries gauge voting power, which has its own market value. The full emission schedule and locking math are mapped out in CRV tokenomics and the veCRV model. With CRV trading near $0.25 as of June 2026, this is a small-cap token backed by measurable, recurring cash flow.

UNI spent its first seven years as a pure governance token with no claim on fees. That changed in December 2025, when holders approved the UNIfication proposal, burning 100 million UNI worth nearly $600 million at the time and switching on protocol fees that fund ongoing burns, as reported by CoinDesk. The mechanism routes fee revenue into a contract that lets holders redeem and destroy UNI, making the supply deflationary. We unpack how it works in our Uniswap fee switch explainer.

The two models reward holders differently. Curve pays out directly: lock, vote, and claim crvUSD every week. Uniswap accrues value indirectly through supply reduction, and its far larger fee base means the absolute dollars involved are bigger. Relative to market cap, though, Curve distributes a higher share of what it earns, which is why veCRV yields have stayed attractive even through CRV's price drawdowns.

Where the Liquidity Comes From

Gauges, bribes, and the Curve Wars

Curve directs its CRV emissions to pools according to gauge weights set by veCRV voters. That design turned governance power into a yield-bearing asset and triggered the Curve Wars, a multi-year contest in which protocols like Convex accumulated veCRV and stablecoin issuers paid incentives to voters who deepened their pools. The system still works the same way in 2026: liquidity on Curve follows emissions and vote incentives as much as organic fees. Curve also earns beyond swaps through crvUSD, its native overcollateralized stablecoin, whose borrowing interest flows back to veCRV holders and gives the DAO revenue that does not depend on trading volume.

How Uniswap pulls in depth

Uniswap historically paid no emissions at all. Liquidity providers show up for organic fee income, and concentrated liquidity lets a smaller amount of capital quote tighter prices than a v2-style pool ever could. With v4, hooks enable pool-level incentive programs, and the ecosystem has funded targeted liquidity campaigns around the hooks rollout. The practical contrast: on Uniswap, liquidity chases volume; on Curve, liquidity chases incentives and the integrations built on top of its pools.

When Traders Reach for Each

Rotating size between stablecoins: Curve. Moving seven or eight figures between USDT, USDC, and other dollar tokens is exactly what the Stableswap invariant was built for, and execution cost usually beats every alternative.

Trading pegged or correlated pairs: Curve again. Liquid staking tokens against ETH, wrapped assets against their originals, and stablecoin-to-stablecoin routes all benefit from liquidity packed tightly around the peg.

New listings, volatile pairs, and everything else: Uniswap. If a token exists on-chain, it almost certainly has a Uniswap pool, and for standard-sized trades in liquid pairs the fee tiers are competitive.

In practice most flow never picks a side manually. Aggregators such as 1inch split orders across both protocols and route each leg wherever execution is best. Whichever venue you use, you will be connecting a self-custody wallet, and our guide to the best CRV wallets covers solid options for holding CRV and interacting with DeFi safely.

Curve vs Uniswap FAQ

Is Curve cheaper than Uniswap?

For large trades between like-priced assets, yes. Curve's stable pools charge 0.01% to 0.04% and keep slippage minimal even on multi-million dollar swaps. For volatile pairs and ordinary retail-sized trades, Uniswap's 0.01% to 0.30% tiers and deeper general-purpose liquidity usually make it equal or cheaper.

Can Uniswap v4 hooks replicate Curve's Stableswap?

Technically, yes. Hooks allow custom pricing curves, so a developer can deploy a Stableswap-style pool on Uniswap v4. In practice, Curve still holds the deepest pegged-asset liquidity, the gauge incentives that retain it, and years of integrations with stablecoin issuers and lending protocols, so the moat is ecosystem depth rather than math.

Which is better for liquidity providers, Curve or Uniswap?

It depends on risk appetite. Curve LPs in stable pools face minimal impermanent loss and stack swap fees with CRV emissions, making it the lower-maintenance option. Uniswap v3 and v4 LPs can earn more per dollar through concentrated positions, but volatile pairs carry real impermanent loss and ranges need active management.

Picking the Right Tool for the Trade

Curve and Uniswap stopped competing for the same trade years ago. Uniswap is the general marketplace, with unmatched breadth, the most volume, and a token that finally accrues value through burns. Curve is the specialist, with the best execution in pegged assets and a revenue-sharing model that has paid lockers since 2020. Anyone weighing the token side of this comparison should also read our CRV price prediction, which looks at how fee revenue, emissions, and lock rates interact with price.
