Uniswap Fees: What You Really Pay to Swap Crypto

When you swap tokens on Uniswap, a decentralized exchange built on Ethereum that lets users trade crypto without intermediaries. Also known as a DEX, it's one of the most used platforms for trading Ethereum-based tokens—but what you pay isn't always obvious. The fee you see on the screen? That’s just part of the story. There’s also gas fees, the cost to process your transaction on the Ethereum blockchain, paid in ETH, and liquidity provider fees, the 0.05% to 1% charge built into every trade that goes to people who supply the trading pairs. These aren’t optional. They’re baked in.

Uniswap V3 changed everything by letting liquidity providers set custom price ranges. That means fees vary depending on how active a trading pair is. If you’re swapping ETH for USDC, you’re likely paying 0.05%. But if you’re trading some obscure token with low volume, the fee might jump to 0.3% or even 1%. And don’t forget slippage—when the price moves between when you click ‘swap’ and when it executes, you lose more than you expected. A 2% slippage on a $1,000 trade isn’t a typo—it’s common on thin markets. This is why many traders avoid small-cap tokens on Uniswap: the hidden costs eat your profit before you even cash out.

There’s no way around these fees. You can’t skip gas. You can’t dodge liquidity provider charges. But you can outsmart them. Trade during low network congestion. Use layer-2 solutions like Arbitrum or Optimism where fees are 90% cheaper. Check the fee tier before you swap. And never assume the price you see is the price you’ll get. The real cost of using Uniswap isn’t just the number on the button—it’s everything underneath it.

Below, you’ll find real reviews and deep dives on platforms that compete with Uniswap, scams that mimic its interface, and how to spot when a DEX is just a money trap. Some posts show you how to save on fees. Others warn you about exchanges that look like Uniswap but aren’t. All of them cut through the noise and show you what actually matters when you’re trading crypto.
