Why is Uniswap so Expensive – 3 Ways to Reduce Fees?

This post was originally published in [2021] and has been fully updated for 2026 with new data and tools.

If you just tried to swap $100 and saw a $45 gas estimate, you’re likely asking, ‘Why is Uniswap so expensive?’

In 2026, high Ethereum congestion still plagues mainnet traders, but you don’t have to overpay. This guide breaks down 3 ways to reduce fees, including a secret tip for gasless swaps that most retail traders completely overlook.

• Shift to “intent-based” trading
• Migrate to Unichain, a layer 2
• Enable “Gasless” approval

Keep reading, and I’ll share what’s so special about Uniswap and what the token does. I’ll also share a few other DEXs you can use to reduce your fees.

Stop overpaying: 3 ways to reduce Uniswap fees using Unichain and UniswapX

• Shift to "intent-based" trading

Instead of submitting a transaction and paying the gas yourself, you sign an "intent."

Basically, fillers compete to settle your trade; they pay the gas and bundle them. If the trade fails, you pay $0

• Migrate to Unichain, a layer 2

In 2021, everything was on the Mainnet; in 2026, there is a second layer. A swap on mainnet might be $15 to $40, and on the second layer, it could be 5 cents.

• Enable "Gasless" approval

Modern smart wallets allow you to sign approvals off-chain before the swap. This could save you $5 to $15.

Tired of high gas? The step-by-step guide to lowering Uniswap transaction costs

The first way to reduce fees is by converting Ethereum to wrapped Ethereum, called Weth first. It will look something like...

The second way is to shop around for a better exchange.

One exchange is Polygon that uses a Layer 2 solution called "Matic." You could think of a layer 2 solution, where instead of having TONS of tiny transactions, there is 1 large transaction that has many tiny ones in it.

This could save you money in gas fees.

Oh, and you would be using a service called Quickswap, which is similar to Uniswap. You can learn more about Quickswap by clicking on the link HERE.

There are other exchanges as well. The one I really like is "Defi Chain," which is unique because it's based on Bitcoin. You can use the code 939517 for $30 in free coins if you make a deposit of over $50.

The last item is to tweak Metamask to save money on gas fees.

One way to reduce gas fees "on Metamask" is to click on the round icon on the top right and click on Settings. Next, scroll down to Advanced and turn on Advanced gas controls. 

This enables you to save more money on gas fees. Now, when you send something, you can type in the gas prices that you would see on an Ethereum gas station. 

Another idea is to wait and see if the prices drop. Maybe in the middle of the night, gas prices will be less expensive. 

Here is a post on how you can save more money using Metamask by clicking on the link HERE.

What makes Uniswap v4 unique? How "Hooks" and Singleton architecture save you money

Uniswap is decentralized, and this has some advantages to normal exchange.

One advantage is your helping the little guy, who are small people trying to earn money with their crypto.

There is no KYC verification for the exchange and no central exchange rules.

Uniswap is the biggest DEX and started in 2018 with no ICO "initial coin offering."

Someone can connect to Uniswap with Metamask. You do remain in control of your coins the entire time, unlike an exchange.

Apart from being an exchange, Uniswap has a feature that allows you to pay someone in a token you don't hold.

Uniswap just launched V3 on July 13, 2021. The problem is that the update did little to address the HIGH gas prices on the Ethereum network.

The fees you will pay are usually $30 and sometimes MUCH higher for gas on each Uniswap trade.

Oh, and there are other fees, such as liquidity provider fees (it's 0.30%). Liquidity provider fees are there to incentivize people to provide liquidity to the exchange; otherwise, why would they do it?

There is also something called slippage.

Slippage is the real-time price when you make a trade that is different than the market price. The bigger the amount you trade, the higher the slippage can be.

Lastly, is the "price impact," which is the difference between the market price and the estimated price.

Price impact and slippage sound similar, but they are a little different.

Lastly, apart from making trades on the platform, you can actually earn money by providing liquidity. In return for adding liquidity, "the same amount of tokens on each pair," you would get some high returns.

The risks are the same as if you purchased the tokens and the price dropped a lot.

The problem with Uniswap is the high fees to move Ethereum. This is why I'm a fan of using Defi Chain because there are MUCH lower fees.

What is the UNI Token? How to earn yield from Uniswap protocol fees and staking

If Uniswap allows someone to swap Ethereum for another token, what is the point of the Uniswap token?

The Uniswap token is a governance token. By having a governance token, someone can vote on ideas that control the Uniswap exchange.

Some of these ideas could be how new tokens are distributed to people. Maybe there is a proposal to the fee structure, and by holding the Uniswap token, you can vote on it.

The real reason the token was created was to incentivize people to NOT go to SushiSwap, another DEX that was forked from Uniswap.

Sushi Swap wanted to reward people with Sushi tokens to move to the platform, and Uniswap wanted to reward people with its tokens to stay.

There are 520 million of these tokens in circulation, and a supply limit of 1 billion will be created.

Uniswap vs. PancakeSwap and Aerodrome: Which DEX has the lowest fees in 2026?

All 3 offer very competitive fees.

Uniswap isn't the only decentralized exchange, and there are "many" others. One DEX, that I have to mention is Defi Chain.

What makes DEFI unique is that it's not based on Ethereum, which nearly ALL DEX's are.

DEFI chain is based on Bitcoin, and it's Non-Turing complete, which is a fancy way of saying its more simple with fewer things that can go wrong.

Oh, and the gas fees are going to be MUCH less because it's not Ethereum.

I know the creators of Defi chain; they have BIG plans for the future of the project and a large community. The best part is that you can earn some "killer" rewards for being a part of the project.

Conclusion: Why is Uniswap so Expensive - 3 Ways to Reduce Fees?

Apart from Defi Chain, there are many other exchanges. I recommend looking at 2 or 3 choices and going with the exchange that saves you the most money.

Crypto is risky, exciting, unpredictable, and crazy!

It's not a bad idea to diversify, and 1 idea that I've always been a fan of is affiliate marketing. You can do it anywhere, anytime, around your schedule, in nearly any niche, and it's tons of fun.

I've been at it for 15 years, and even better, I'm giving away FREE guides on many of my secrets HERE.
