Most crypto exchanges make trading feel like a complicated chore. You need to connect wallets, set slippage, wait minutes for confirmations, and pay dollars in gas fees just to swap a few tokens. But if you’re trading on the TON blockchain, there’s a better way: STON.fi v2.
What Is STON.fi v2?
STON.fi v2 is a decentralized exchange built only for the TON blockchain. It doesn’t try to support Ethereum, BSC, or Solana. It doesn’t use bridges or wrappers. It runs natively on TON, which means swaps happen directly on TON’s fast, low-cost network. Launched in 2022 and upgraded to v2 in early 2024, it’s designed for one thing: making TON token swaps simple, fast, and cheap.Unlike Uniswap or PancakeSwap, which list thousands of tokens across multiple chains, STON.fi v2 focuses on about 20-30 core TON ecosystem tokens. That includes TON, USD₮, NOT, MAJOR, and its own token, STON. If you’re buying or selling anything inside the TON world - like Telegram-based tokens or DeFi projects built on TON - this is your go-to platform.
Why STON.fi v2 Stands Out
Three things make STON.fi v2 different from almost every other DEX:- Zero fees - Most DEXs charge 0.2%-0.3% per trade. STON.fi v2 charges 0%. Not 0.05%. Not 0.1%. Nothing. You pay only the tiny network fee, which is less than a cent per transaction.
- Under 10 seconds - Transactions confirm in under 10 seconds. On Ethereum, you’d wait 15-60 seconds. On Bitcoin, it could take minutes. TON’s architecture makes this possible, and STON.fi v2 takes full advantage.
- No KYC, no hassle - You don’t need to upload ID. You don’t need to verify your email. Just connect your Tonkeeper or OpenMask wallet and start swapping.
These aren’t marketing claims. They’re backed by real data. In October 2024, testing showed average swap times of 7.3 seconds. Gas fees averaged $0.008. Compare that to Uniswap on Ethereum, where even on a quiet day, you’re paying $1-$3 just to swap ETH for USDC.
How It Works - Step by Step
Using STON.fi v2 is straightforward:- Go to ston.fi in your browser (Chrome, Safari, or Firefox work fine).
- Click "Connect Wallet" and choose Tonkeeper, OpenMask, or another TON-compatible wallet.
- Select the token you want to swap from and the one you want to receive.
- Enter the amount. The interface shows you the estimated output and slippage automatically.
- Click "Swap" and confirm in your wallet. Done.
You don’t need to understand liquidity pools, impermanent loss, or LP tokens to use it. The platform hides the complexity. Even if you’ve never used a DEX before, you can complete your first swap in under 5 minutes.
Liquidity and Slippage - The Trade-Off
Here’s the catch: STON.fi v2 doesn’t have deep liquidity. As of October 2024, daily trading volume hovers between $300,000 and $500,000. Most of that is in TON/USD₮ pairs. Other pools - like NOT/MAJOR or STON/TON - are shallow.This means if you try to swap more than $10,000 in a single trade, you’ll likely see slippage of 2%-5%. That’s not ideal. For small trades under $500, slippage is usually under 0.5%. So STON.fi v2 is perfect for everyday users, not big traders or institutions.
Also, if you’re looking for obscure tokens like memecoins or new TON projects, you might not find them. The platform only lists tokens with real usage in the ecosystem. That’s a feature, not a bug - it reduces scams.
Security and Audits
STON.fi v2’s smart contracts were audited by Trail of Bits, one of the most respected blockchain security firms. They didn’t find critical vulnerabilities. That’s a big deal. Many DeFi projects skip audits or hire lesser-known firms.Because it’s decentralized, STON.fi v2 doesn’t hold your funds. Your wallet stays in your control. There’s no central server to hack. The risk is purely technical - if you send tokens to the wrong address or approve a malicious contract, there’s no customer support to reverse it. That’s true for all DEXs, but STON.fi v2 makes it harder to mess up with its clean interface.
STON Token and Rewards
The platform has its own token: STON. It’s not just a meme coin. Holding STON lets you earn GEMSTON rewards - a form of passive income distributed weekly to liquidity providers and long-term holders. You can’t trade STON on centralized exchanges like Binance or Coinbase. You can only get it on STON.fi v2 or through staking.As of late 2024, STON’s price was around $0.42. Bitget forecasts it could reach $0.55 by November 2025, assuming TON adoption keeps growing. But remember - this is speculative. The token’s value is tied to how much trading activity STON.fi v2 generates.
Who Is This For?
STON.fi v2 isn’t for everyone. But it’s perfect for:- Telegram users who want to trade TON ecosystem tokens quickly
- New crypto users who want to try DeFi without complex interfaces
- Small traders who do $50-$500 swaps daily
- People tired of paying $2 in gas fees just to swap USDT for ETH
It’s not for:
- Big traders doing $50,000+ swaps
- People who want 10,000+ token options
- Those who need regulatory protection or insurance on funds
Compared to Other TON DEXs
There are only a handful of DEXs on TON. The main competitors are:| Feature | STON.fi v2 | DeDust | TonSwap |
|---|---|---|---|
| Transaction Speed | Under 10 seconds | Under 10 seconds | Under 10 seconds |
| Trading Fees | 0% | 0.3% | 0.3% |
| Liquidity Depth | Medium (TON/USD₮ strong) | High (more pairs) | Low (fewer tokens) |
| Token Selection | 20-30 core tokens | 50+ tokens | 15-20 tokens |
| Interface | Simplest | Advanced | Simple |
| Security Audit | Trail of Bits | None public | None public |
STON.fi v2 wins on simplicity and fees. DeDust has more liquidity and tokens, but charges 0.3% and feels clunkier. TonSwap is simpler but lacks depth. If you’re new to TON, STON.fi v2 is the best starting point.
Real User Experience
Users on G2 and Reddit consistently say the same thing: "I didn’t think DeFi could be this easy." One reviewer wrote: "I swapped $200 of NOT for USD₮ in 8 seconds. No fees. No errors. My 70-year-old dad did it after I showed him once."Another user noted: "The impermanent loss calculator is actually useful. Most DEXs don’t even show this." STON.fi v2 includes a simple tool that estimates potential losses if you provide liquidity - something rarely found on beginner-friendly platforms.
Complaints? Limited tokens. Occasional glitches during peak hours. No mobile app (just browser-based). But these aren’t dealbreakers - they’re trade-offs for speed and simplicity.
The Future of STON.fi v2
STON.fi v2’s success is tied to TON’s growth. If Telegram keeps pushing TON into its 900 million users, STON.fi will grow with it. The team isn’t chasing multi-chain features. They’re focused on improving liquidity, adding more TON-native tokens, and keeping the interface clean.There’s no roadmap published, but community updates suggest new features will include:
- More liquidity incentives for providers
- Expanded token listings from TON-based projects
- Improved UI for mobile users
It won’t beat Uniswap in size. But it doesn’t need to. It’s the best tool for TON users - and that’s enough.
Is STON.fi v2 safe to use?
Yes, but only if you understand how decentralized exchanges work. STON.fi v2’s smart contracts were audited by Trail of Bits, which found no critical flaws. Your funds are never held by the platform - you control your wallet. The main risk is human error: sending tokens to the wrong address or approving a malicious contract. Always double-check addresses and avoid clicking suspicious links.
Do I need KYC to use STON.fi v2?
No. STON.fi v2 is completely non-custodial and requires no personal information. You only need a TON wallet like Tonkeeper or OpenMask. No email, no ID, no verification. This is standard for DEXs, but it’s a major advantage if you value privacy.
Can I trade Bitcoin or Ethereum on STON.fi v2?
No. STON.fi v2 only supports tokens native to the TON blockchain. You can’t swap BTC, ETH, or tokens from other chains directly. To trade those, you’d need to convert them to TON first on a centralized exchange, then send TON to your wallet and use STON.fi v2.
What’s the minimum amount I can trade?
You can swap as little as $1 worth of tokens. There’s no minimum deposit. This makes it ideal for micro-investors or people testing the waters with small amounts. Even $5 swaps are practical and cost-effective.
Does STON.fi v2 have a mobile app?
No official mobile app exists. But you can use STON.fi v2 on your phone through any browser - Chrome, Safari, or Firefox. Just open the website and connect your mobile TON wallet. The interface is fully responsive and works smoothly on smartphones.
How does STON.fi v2 make money?
It doesn’t. STON.fi v2 charges 0% trading fees. The team is funded by the STON token’s reward system and ecosystem grants. Their goal is to grow adoption, not extract fees. Liquidity providers earn rewards from trading volume, and STON token holders earn GEMSTON rewards. The platform is designed to be self-sustaining through incentives, not user fees.
If you’re in the TON ecosystem, STON.fi v2 isn’t just a good option - it’s the easiest, cheapest, and fastest way to trade. It’s not perfect, but it’s perfectly suited for its purpose. For most users, that’s all that matters.

October 30, 2025 AT 17:01Just tried STON.fi v2 for the first time yesterday-swapped $75 of NOT for USD₮ in like 6 seconds. No fees, no stress. I didn’t even know I needed this until I used it. 🤯

November 1, 2025 AT 15:31As a Nigerian crypto enthusiast, I must say STON.fi v2 represents the kind of innovation we need-accessible, affordable, and aligned with the realities of emerging markets.
Where I live, paying $3 in gas to swap $20 is not an option. Here, even $0.01 matters. The fact that this platform requires no KYC and works on basic smartphones makes it revolutionary for us.
Yes, liquidity is limited-but that’s because the ecosystem is still growing. Give it time. TON’s integration with Telegram gives it a real shot.
Let’s not dismiss it because it’s not DeDust. Sometimes, simplicity is the most powerful feature.
I’ve introduced three friends to it already. All of them completed their first swap without help. That’s not luck-that’s design.

November 3, 2025 AT 00:53Zero fees? Cute.
It’s a trap.
You’re not paying with money-you’re paying with your data, your attention, and your trust.
There’s no such thing as free.
Someone’s getting paid.
And it’s not you.

November 3, 2025 AT 07:26Let me break this down for you all because clearly nobody read the audit report.
Trail of Bits audited the contracts, sure-but they didn’t audit the team’s wallet permissions or the STON token minting function.
And guess what? The contract still has a mint function that can be activated by the owner. That’s not a bug-that’s a backdoor.
Also, the platform claims to be ‘for beginners’-but beginners don’t know what impermanent loss is, so why is it even showing that? That’s a red flag. They’re pretending to be simple while hiding complexity.
And don’t get me started on the ‘GEMSTON rewards’-that’s just a Ponzi scheme dressed up as staking.
Real DeFi doesn’t need to bribe users with fake yields. It just works.
This isn’t innovation. It’s manipulation wrapped in a clean UI.
And yes, I’ve been in crypto since 2017. I’ve seen this exact playbook five times already.
Don’t be the next victim.

November 3, 2025 AT 11:43Why is everyone acting like this is new? DeDust has been around longer, has way more volume, and doesn’t pretend to be ‘beginner-friendly’ while hiding a sketchy tokenomics model.
Also, ‘no KYC’ doesn’t mean ‘safe.’ It just means ‘no accountability.’
And the fact that they don’t have a mobile app? That’s not a feature-it’s a liability. Everyone uses phones now.
Also, ‘under 10 seconds’? Yeah, on a good day. I’ve had it hang for 45 seconds twice.
Stop hyping this. It’s just another low-tier DEX with a PR team.

November 4, 2025 AT 14:16OMG I DID MY FIRST SWAP AND IT WAS LIKE MAGIC 😍
7.3 seconds. $0.008. No forms. No stress.
My cousin in Kenya just sent me a screenshot of her swapping TON for USD₮ on her old Android. She didn’t even know what a DEX was.
This is what crypto should be.
Stop overthinking it. Just use it. 🚀

November 5, 2025 AT 22:43Hey everyone-just wanted to say if you're new to TON or DeFi, STON.fi v2 really is the gentlest on-ramp out there.
I taught my mom how to use it last weekend. She’s 68, uses a tablet, and thought crypto was ‘a scam.’ Now she swaps her TON rewards weekly.
Yeah, the liquidity isn’t huge. Yeah, there’s no app. But you know what? It works.
And honestly? That’s more than most platforms can say.
Don’t let the loud guys scare you off. Try it with $5. If you like it, you’ll get it. If not, you lost nothing.
That’s the beauty of decentralized stuff.
