Ubeswap Gas Fee Calculator
If you're trading crypto on Optimism, you've probably heard of Ubeswap. It's the native decentralized exchange for the Optimism network - a Layer 2 solution built to make Ethereum cheaper and faster. But here’s the real question: is Ubeswap actually useful, or is it just another niche platform struggling to stay alive?
What Is Ubeswap, Really?
Ubeswap isn’t a new app you download. It’s a decentralized exchange (DEX) that runs entirely on Optimism. Think of it like Uniswap, but built specifically for Optimism’s network. It launched in 2021 as a fork of Uniswap V2, meaning it uses the same basic math to swap tokens - no order books, no middlemen. You connect your wallet, pick two tokens, and click swap. That’s it.Unlike centralized exchanges like Binance or Coinbase, Ubeswap doesn’t hold your crypto. You keep your keys. No KYC. No account signup. That’s the whole point of DeFi. But here’s the catch: you need to understand Layer 2 first. If you don’t know how to bridge ETH or USDC from Ethereum mainnet to Optimism, you won’t be able to trade on Ubeswap at all.
How Does Ubeswap Compare to Other DEXs?
Let’s get real about numbers. As of October 2025, Ubeswap has $14.7 million locked in its pools. That sounds like a lot until you compare it to the giants. Uniswap on Optimism alone has over $1.2 billion. PancakeSwap on BNB Chain? $2 billion. Even iZiSwap on Optimism has more than five times Ubeswap’s TVL.Ubeswap’s daily trading volume? Around $47,000. That’s less than what some single tokens on Uniswap move in an hour. Why does this matter? Low volume means high slippage. If you try to swap more than a few hundred dollars’ worth of OP or USDC, you’ll likely get a terrible price. One Reddit user swapped 5 ETH worth of OP and ended up with 12% less than expected. They switched to Uniswap’s Optimism pool - same gas fee, better rate.
Ubeswap also lacks features most traders expect. No limit orders. No stop-losses. No advanced charting. No margin trading. It’s a simple swap tool. If you want to trade strategically, you’ll need to use a different platform.
Speed and Cost: Where Ubeswap Actually Shines
Here’s where Ubeswap wins: cost and speed. On Ethereum mainnet, swapping tokens can cost $3-$10 in gas. On Ubeswap? Around $0.03. That’s not a typo. Gas fees on Optimism average 0.1-0.3 gwei. Transactions confirm in 2-5 seconds. That’s faster than most bank transfers.For small, frequent swaps - like moving between OP, USDC, or DAI - Ubeswap is unbeatable. If you’re just holding Optimism-native tokens and need to rebalance your portfolio without paying a fortune, this is the place.
But remember: you need to get your assets onto Optimism first. Bridging from Ethereum can take 4-7 days if you use the standard withdrawal. There’s a faster option - but it costs more. If you’re not ready for that complexity, Ubeswap won’t help you.
Wallets, Security, and Ease of Use
You can connect Ubeswap with MetaMask, Coinbase Wallet, Ledger, or any wallet that supports Optimism. Setup is straightforward: add the Optimism network (chain ID 10), bridge your assets, then go to ubeswap.org. No login. No email. No password.Security-wise, Ubeswap inherits Uniswap V2’s code, which has been battle-tested for years. No major exploits have occurred. But it doesn’t have the latest upgrades from Uniswap V3 - like concentrated liquidity or improved oracle systems. The Block rated its security architecture 6.8/10. Solid, but not cutting-edge.
One common issue users report: failed transactions due to bad gas estimates. The platform sometimes underestimates the cost, especially during network spikes. The fix? Manually raise the gas limit in your wallet. Ubeswap’s documentation tells you how - but it’s buried. Most users don’t find it until they’re stuck.
Who Is Ubeswap For?
Ubeswap isn’t for beginners. It’s not for people who want to buy crypto with a credit card. It’s not for traders doing large orders. It’s not even for most casual DeFi users.It’s for one group: experienced crypto users who already use Optimism and need to swap small amounts of native tokens without paying high fees. If you’re holding OP, staking on Optimism, or using apps like Synthetix or Velodrome on Layer 2, Ubeswap is a handy tool.
But if you’re trying to trade new tokens, large amounts, or tokens not listed on Optimism, you’ll hit walls. Ubeswap supports only ERC-20 tokens native to Optimism or bridged from Ethereum. No Solana tokens. No Tron tokens. No BSC tokens. You’re locked into the Optimism ecosystem.
The Bigger Picture: Is Ubeswap Going to Survive?
This is the most important part. Ubeswap’s future is tied to Optimism’s. If Optimism grows, Ubeswap might grow with it. If Uniswap expands its Layer 2 support - which it already is - Ubeswap could vanish.Delphi Digital estimates Ubeswap has only a 32% chance of surviving three more years. Messari calls it “high risk.” Why? Because as Optimism gets bigger, users will naturally migrate to Uniswap’s deeper pools, even if fees are slightly higher. Why use a small DEX with 100 tokens when you can use one with 5,000?
Ubeswap’s team is trying to stay relevant. They’re preparing for Optimism’s Bedrock upgrade in early 2026 and planning to join the Superchain initiative. That could mean better integration with Base and Worldcoin. But these are long-term bets. Right now, they’re fighting a losing battle.
What Users Are Saying
Trustpilot shows a 2.7/5 rating from just 17 reviews. That’s not enough for a solid average, but the complaints are consistent: “Too little liquidity,” “Slippage kills big trades,” “Interface feels outdated.”Positive reviews? Only one thing comes up: “Gas fees were $0.03.” That’s it. No one says, “I found amazing tokens here.” No one says, “It’s the best DEX I’ve used.” Just, “It’s cheap.”
Web traffic? Only 1,550 monthly visits. That’s less than a small blog. The Telegram group has 2,347 members - but only 12 messages a day. The GitHub repo has three developers and 17 commits in 30 days. That’s not a thriving project. That’s maintenance mode.
Final Verdict: Should You Use Ubeswap?
Yes - if you’re already on Optimism and you’re doing small swaps. If you’re holding OP, USDC, or DAI and want to trade them without paying $5 in gas, Ubeswap is your best option.No - if you’re new to crypto, want to trade large amounts, need advanced tools, or plan to hold altcoins not on Optimism. You’ll waste time and money.
Ubeswap isn’t broken. It’s just small. It’s not failing because it’s bad. It’s failing because the market moved on. Uniswap, SushiSwap, and even iZiSwap are offering more liquidity, more tokens, and better tools - all on Optimism too.
If you’re a power user who understands Layer 2 and values low fees above all else, Ubeswap still has a place in your toolkit. But if you’re looking for the future of DeFi trading, you’re better off watching Uniswap’s next move.
Is Ubeswap safe to use?
Yes, Ubeswap is safe for small trades if you’re using a trusted wallet like MetaMask or Ledger. It’s built on the same code as Uniswap V2, which has been audited and used for years. But since it’s non-custodial, you’re responsible for your own funds. If you send tokens to the wrong address or approve a malicious contract, there’s no way to reverse it. Always double-check token addresses and approval amounts.
Can I buy crypto with fiat on Ubeswap?
No. Ubeswap is a decentralized exchange - it only swaps crypto tokens. You cannot deposit USD, EUR, or any fiat currency. To use Ubeswap, you must first buy crypto on a centralized exchange like Coinbase or Kraken, then bridge it to Optimism using a bridge like the Optimism Gateway. Only then can you trade on Ubeswap.
What tokens can I trade on Ubeswap?
You can trade ERC-20 tokens native to the Optimism network. This includes OP (Optimism’s native token), USDC, DAI, WETH, and other tokens that have been bridged from Ethereum mainnet. It does not support tokens from other chains like BNB Chain, Solana, or Tron unless they’ve been wrapped and bridged to Optimism. Always check if a token is listed on the Optimism token directory before trading.
Why is my transaction failing on Ubeswap?
Failed transactions usually happen because the gas fee estimate is too low. Ubeswap sometimes underestimates the cost, especially during peak times. To fix this, manually increase the gas limit in your wallet (MetaMask or similar) before confirming. You can also check the current gas prices on Optimism’s network dashboard. If you’re still having issues, your wallet may not be connected to the correct network - make sure you’re on Optimism (chain ID 10), not Ethereum mainnet.
Does Ubeswap have a mobile app?
No, Ubeswap doesn’t have a dedicated mobile app. You can access it through your mobile browser using a Web3 wallet like MetaMask or Coinbase Wallet. The interface works fine on phones, but it’s not optimized for touch. For better mobile trading, consider using a DEX aggregator like 1inch or ParaSwap, which support Optimism and have better mobile UX.
Is Ubeswap better than Uniswap on Optimism?
For most users, no. Uniswap on Optimism has far more liquidity, more token pairs, lower slippage, and a more polished interface. Ubeswap’s only advantage is slightly lower fees in rare cases - but the difference is negligible. Unless you’re specifically trying to support Optimism’s native DEX, Uniswap is the better choice. Ubeswap exists more as a legacy option than a competitive alternative.

November 7, 2025 AT 17:16Ubeswap is like a quiet library in a city of loud concerts. It doesn't shout. It doesn't dazzle. But if you need silence, it's perfect.
Benjamin Jackson
November 9, 2025 AT 16:25I’ve used Ubeswap for small OP swaps for months now. Gas is basically free, and it just works. I don’t need fancy charts or limit orders-just speed and cheapness. It’s not for everyone, but for my use case? Perfect.

November 10, 2025 AT 08:55It’s funny how we treat DEXs like they’re all supposed to be giants. 🌱 Ubeswap is a bonsai tree in a forest of redwoods. It’s not trying to be the tallest-it’s just thriving in its own soil. Optimism’s ecosystem needs niche tools like this. Without them, everything becomes homogenized. And homogenized DeFi? That’s when things get boring.
Also, the fact that it’s still alive after 4 years with 3 devs and 17 commits? That’s not failure. That’s sustainability.
Uniswap is the Ferrari. Ubeswap is the bicycle that gets you to the coffee shop without costing you a kidney.
And yes, I’ve had failed txs too. But I learned to bump the gas limit manually. It’s not hard. It’s just… different.
People forget: DeFi isn’t about maximizing volume. It’s about sovereignty. Ubeswap doesn’t gatekeep. No KYC. No ads. No algorithmic manipulation. Just code and trustlessness.
If you’re mad it doesn’t have 5000 tokens, you’re missing the point. It’s not a supermarket. It’s a toolshed.
Also, the Bedrock upgrade might change everything. Optimism’s Superchain vision could turn Ubeswap from a relic into a cornerstone.
Stop judging it by Uniswap’s standards. Judge it by its own mission: low-cost, simple swaps for the Optimism-native crowd.
And if you’re still using Ethereum mainnet to swap $5 worth of tokens? 😅
Ubeswap is the quiet rebel. And honestly? I respect that.

November 10, 2025 AT 10:07Let’s be brutally honest: Ubeswap is a ghost town with a fancy UI. The fact that it has $14.7M TVL while Uniswap has over a billion on the same chain? That’s not a niche-it’s a funeral. And the trading volume? Less than a single whale’s morning snack. This isn’t a platform. It’s a museum exhibit labeled 'Early DeFi Experiment - Do Not Touch.' If you’re still using it, you’re not a pioneer-you’re a relic collector.
Leo Lanham
November 10, 2025 AT 22:48Ubeswap? LOL. Why even bother? It’s like using a flip phone in 2025. Everyone knows Uniswap is the real deal. If you're not using Uniswap on Optimism, you're either clueless or masochistic. Stop pretending this is a 'tool'-it's a dead end.
Brian Webb
November 11, 2025 AT 12:57I used to think Ubeswap was pointless until I started doing micro-swaps daily. I move between OP, USDC, and DAI-maybe $200 at a time. On mainnet? $5 in gas. On Ubeswap? Less than a penny. That’s not a feature. That’s a revolution for small holders.
I don’t trade big. I don’t need limit orders. I just need to rebalance without bleeding money. Ubeswap does that. Simple. Quiet. Effective.
And yeah, the interface is basic. But it’s not broken. It’s intentional. No fluff. No distractions. Just swap.
If you’re mad it doesn’t have 10,000 tokens, maybe you’re the one who needs to simplify.
Whitney Fleras
November 13, 2025 AT 00:44I appreciate how honest this review is. Too many people act like every DEX should be a giant. But not everyone needs to trade $50k. Some of us just want to move small amounts without getting ripped off. Ubeswap does that. And honestly? That’s enough.
Colin Byrne
November 13, 2025 AT 04:02Let’s address the elephant in the room: Ubeswap’s existence is a statistical anomaly. The fact that it still operates with a team of three and a user base smaller than a mid-tier Discord server suggests either profound inefficiency or a cult-like devotion to a dying ideology. The $0.03 gas fee is irrelevant if the entire ecosystem is collapsing under its own irrelevance. Why would any rational actor choose a DEX with 1,550 monthly visits when Uniswap offers 100x the liquidity at near-identical cost? The answer is simple: they wouldn’t. Ubeswap is not a tool-it’s a monument to misplaced loyalty. The only thing more tragic than its decline is the people who still defend it as 'authentic.' Authenticity without utility is just nostalgia dressed in smart contracts.

November 14, 2025 AT 09:52Ubeswap is a trap. They want you to think it's safe because it's 'non-custodial.' But what they don't tell you is that Optimism is controlled by a small group of insiders who control the bridge. Your 'decentralized' swap? It's just a front. They're slowly draining liquidity and pushing users to their own centralized products. Watch closely-next year, they'll force everyone to use their new 'Superchain' wallet. You think you're free? You're already owned.
Robert Bailey
November 15, 2025 AT 11:46Ubeswap is the quiet friend who shows up with soup when you’re sick. Not flashy. Not loud. But always there when you need it. Low fees? Yes. Simple? Yes. Not for everyone? Absolutely. But for those who get it? It’s gold.
Wendy Pickard
November 15, 2025 AT 20:36I’ve used Ubeswap for months. Never had a problem. Gas is crazy low. I swap OP for USDC every week. I don’t need a fancy interface. I just need it to work. And it does.
Jeana Albert
November 17, 2025 AT 05:21Ubeswap is a joke. The fact that people still use it is embarrassing. You’re paying $0.03 in gas but getting 12% slippage? That’s not savings-that’s robbery. And the team hasn’t updated the UI since 2022? You’re not a DeFi user-you’re a masochist. Stop romanticizing incompetence.
Sunidhi Arakere
November 17, 2025 AT 09:49I use Ubeswap only for small swaps. It’s reliable. Fast. Cheap. I don’t need more than that. Other DEXs are fine for big trades. This one is fine for daily use. Simple as that.
Angie Martin-Schwarze
November 18, 2025 AT 07:32i keep forgetting to bump the gas limit and then i get mad when my tx fails… then i reread the docs and feel dumb. but it still works. low gas is worth the hassle. kinda like using a manual can opener when the electric one breaks. annoying but cheap.
Fred Kärblane
November 20, 2025 AT 04:59Ubeswap is a prime example of a Layer 2-native DEX optimized for micro-liquidity efficiency. The lack of advanced features isn’t a flaw-it’s a deliberate architectural choice to minimize attack surface and reduce complexity overhead. In the context of Optimism’s rollup-centric design, this is a feature, not a bug. The TVL metrics are misleading because they don’t account for velocity. Ubeswap’s token turnover rate is disproportionately high relative to its liquidity depth. It’s not a liquidity pool-it’s a frictionless relay node for small-scale, high-frequency, on-chain portfolio rebalancing. The real question isn’t whether it’s better than Uniswap-it’s whether it fulfills its niche function with superior efficiency. And the answer is yes.
Janna Preston
November 20, 2025 AT 13:01So… if I already have ETH on Optimism, I can just swap directly? No extra steps? And it really is $0.03? I thought I was imagining that. I’ve been using Uniswap because I thought it was the only option. Maybe I’ve been overcomplicating this.
