Imagine finding a trading platform where you pay absolutely zero fees to make a trade. It sounds like a dream for any trader, right? That is exactly how MonoSwap v3 (Blast) is a decentralized cryptocurrency exchange (DEX) and launchpad integrated with the Blast blockchain network. Launched in 2024, it promises a yield-driven ecosystem where costs aren't the barrier. But in the world of DeFi, "free" often comes with a catch. If you are looking for a place to swap tokens on the Blast network, you need to know if this platform is a hidden gem or a liquidity desert.
The Core Appeal: Zero Fees and Blast Integration
The biggest draw of MonoSwap v3 is its fee structure. Most Decentralized Exchanges (DEXs) charge a small percentage of every trade to fund liquidity providers. MonoSwap v3 breaks this mold by offering a 0% maker fee and 0% taker fee. For a small-scale trader, this is theoretically great because your only real cost is the gas fee on the Blast network itself.
Because it is built specifically for the Blast ecosystem, it aims to be the go-to hub for users moving assets into this Layer 2 environment. The platform isn't just about swapping; it also functions as a launchpad. This means it's designed to help new projects get off the ground. However, the gap between the platform's ambition and its actual usage is wide. While it has a decent following on X (formerly Twitter) with over 100,000 followers, the actual trading numbers tell a different story.
Liquidity and Asset Availability: A Major Red Flag
A DEX is only as good as its liquidity. If there aren't enough people putting their coins into pools, you'll experience massive "price slippage"-where the actual price you get is much worse than the market price. This is where MonoSwap v3 struggles significantly. While some data sources suggest it supports about 3 to 4 cryptocurrencies, the volume is alarmingly low.
Depending on who you ask, the 24-hour trading volume fluctuates between roughly $6,000 and $10,000. In the world of crypto, those numbers are almost invisible. For comparison, industry giants like Uniswap handle billions. If you try to trade a significant amount of money on MonoSwap, you likely won't find enough liquidity to execute the trade at a fair price. The most active pair, USDB--3/WETH--14, barely keeps the lights on.
| Feature | MonoSwap v3 (Blast) | Top-Tier DEXs (e.g., Uniswap) |
|---|---|---|
| Trading Fees | 0% Maker/Taker | Typically 0.01% to 0.3% |
| Asset Variety | Very Low (3-4 coins) | Thousands of tokens |
| Liquidity/Volume | Minimal (Under $11k/day) | Extremely High (Billions/day) |
| Trust Score | Very Low / Unrated | High / Industry Verified |
Trust, Safety, and Regulatory Concerns
When you use a decentralized platform, you are essentially trusting the smart contract code. But you also have to look at the reputation of the platform. MonoSwap v3 has some troubling metrics here. CoinGecko gives it a trust score of 0, and BeInCrypto ranks its trustworthiness very low, placing it around the 803rd spot in their rankings. These aren't just random numbers; they reflect a lack of transparency and a lack of proven uptime and security.
Another point to consider is the lack of regulation. Like most DEXs, MonoSwap isn't overseen by any government authority. While that is standard for DeFi, the combination of zero regulation and low trust scores makes it a risky bet for anyone not comfortable with the possibility of losing their funds. There is no one to call if a trade goes wrong or if the platform suddenly vanishes.
User Experience: The Ghost Town Effect
If you've used a Web3 wallet like MetaMask or Coinbase Wallet, getting onto MonoSwap v3 is a breeze. You connect your wallet, switch to the Blast network, and you're ready to go. The interface follows the standard "Swap" layout that most of us are used to. However, the actual user engagement is nearly non-existent.
Data analysis shows a worrying trend. Some reports indicate zero transactions over a 30-day period in late 2025. Web traffic metrics are equally strange-showing almost zero time spent on the page and an anomalous bounce rate. This suggests that people might land on the site, see the lack of activity or a technical glitch, and leave immediately. It feels less like a bustling exchange and more like a ghost town.
Who is this actually for?
Is there any reason to use MonoSwap v3? If you are a "degens" trader who loves hunting for ultra-early projects on the Blast network and you are trading tiny amounts of money, the zero-fee model might be a fun experiment. But for anyone else, the risks far outweigh the rewards. You might save a few cents on fees, but you'll pay for it in slippage or, worse, a total loss of funds due to the platform's lack of established trust.
If you're looking for a reliable way to trade on Layer 2, you're better off sticking with platforms that have deep liquidity pools. Liquidity is the lifeblood of any exchange; without it, a 0% fee is meaningless because you can't actually execute a trade at a price that makes sense.
Is MonoSwap v3 safe to use?
Based on trust scores from CoinGecko and BeInCrypto, MonoSwap v3 is considered high-risk. It has very low trustworthiness ratings and no government regulation, which means there is significant risk when depositing funds.
Does MonoSwap v3 really have 0% fees?
Yes, the platform advertises 0% maker and taker fees. However, you still have to pay the network gas fees required by the Blast blockchain to process your transaction.
What blockchain does MonoSwap v3 operate on?
It is specifically integrated with the Blast blockchain network, making it a specialized DEX for that ecosystem.
Why is liquidity a problem on MonoSwap v3?
With a 24-hour trading volume often under $11,000 and only a few supported assets, there aren't enough funds in the pools. This leads to high slippage, meaning you get fewer tokens than the market price suggests.
How many coins can I trade on MonoSwap v3?
The selection is very limited, typically ranging from 3 to 4 cryptocurrencies, which is significantly lower than most established decentralized exchanges.
Next Steps and Troubleshooting
If you've decided to try MonoSwap despite the risks, here is how to handle it safely:
- Use a Burner Wallet: Never connect your primary hardware wallet or the wallet holding your life savings. Use a fresh wallet with only the funds you are willing to lose.
- Check the Slippage: Before confirming a swap, look at the "Price Impact." If it's higher than 1-2%, you are losing money to slippage, which cancels out the benefit of the 0% fee.
- Verify the Network: Ensure your wallet is set to the Blast network; otherwise, the platform won't be able to detect your balance.
If you find that your trades are failing or the site isn't loading, it's likely due to the low organic traffic and technical instability noted in recent web analysis. In those cases, the best move is to migrate your assets to a more established DEX on the Blast network.

April 6 2026Zero fees are always a marketing gimmick to attract liquidity into a pool that will eventually be drained by a rug pull or a smart contract vulnerability. If there is no revenue from fees, the platform has no sustainable business model to maintain the infrastructure.

April 7 2026Actually, for anyone on Blast, using a burner wallet is the only way to go. I've seen so many these types of 'zero fee' setups end up being phishing sites or having malicious approve functions that drain your whole wallet. Always check the permissions on Revoke.cash after interacting with something this sketchy.
