Uniswap
Uniswap is an automated market maker protocol (v2, v3, v4) with a web app and self-custodial wallet built by Uniswap Labs. Since 2025-12-27 Uniswap Labs charges no interface fee; traders pay the pool's LP fee plus gas.
Cost: You pay no Uniswap Labs interface fee (since 2025-12-27). A swap costs the pool fee plus gas. The pool fee is 0.30% on v2, 0.01%/0.05%/0.30%/1% tiers on v3, and any creator-set fee on v4. A protocol fee carved out of LP fees is live on v2 and select v3 pools. A $1,000 buy-and-sell costs about $0.00 in Uniswap fees.

Uniswap fees
| Fee | Type | Rate | Applies to | Note |
|---|---|---|---|---|
| Uniswap Labs interface fee | platform | 0% | Buy and sell | 'As of December 27, 2025 Uniswap Labs does not charge interface fees.' Covers the web app, wallet and API. |
| v2 pool fee | lp | 0.3% | Buy and sell | With the protocol fee on, 0.25% goes to LPs and 0.05% to the protocol. |
| v3 pool fee | lp | — | Buy and sell | Pool-specific tier of 0.01%, 0.05%, 0.30% or 1.00%. |
| v4 pool fee | lp | — | Buy and sell | No fixed tiers; pool creators set 0-100% and hooks can make fees dynamic. Hook fees may also apply. |
| Protocol fee (fee switch) | protocol | — | Buy and sell | Taken from the LP fee, not added on top: about 1/4 of LP fee on 0.01%/0.05% v3 pools, 1/6 on 0.30%/1% pools. Active on all v2 and select v3 pools on Ethereum mainnet since December 2025; proceeds fund UNI burns. |
| Network gas | network | — | Buy and sell | Paid to the chain. |
How DEX fees work: instead of a platform fee, each swap pays the fee of the pool it routes through (listed above where published). The interface itself may add its own fee.
Platform fees only. On-chain network/priority fees, pool (LP) fees and price impact are extra and vary by trade.
