Want to swap crypto without handing over your keys? STON.fi lets you trade tokens directly from your wallet-no sign-ups, no KYC, no middlemen. It’s not another centralized exchange like Binance or Coinbase. This is DeFi, built for the TON blockchain, and it works like a high-tech vending machine for crypto: insert your token, pick another, and get it instantly. No waiting for order matches. No delays. Just fast, cheap swaps.
How STON.fi Works (No Bridging, No Wrapping)
Most cross-chain swaps need bridges-complex, risky systems that lock your asset on one chain and mint a fake version on another. STON.fi skips that entirely. It uses Hash Time Locked Contracts (HTLC) and a Request for Quote (RFQ) model to swap tokens directly between blockchains. If you want to trade TON for SOL or ETH, it happens in one step. Your assets never leave your wallet. No wrapped tokens. No third-party custody. Just a direct, atomic swap secured by smart contracts.
This isn’t theoretical. Users have successfully swapped TON to Polygon tokens, Ethereum-based tokens, and even Bitcoin via sidechain integrations-all without leaving the STON.fi interface. The protocol pulls liquidity from multiple sources on the fly, ensuring the best price and lowest slippage. It’s not magic. It’s smart routing, powered by TON’s fast, sharded blockchain.
Fees and Costs: Almost Free
STON.fi charges a flat 0.3% fee on every swap. That’s standard for DeFi. But here’s the breakdown: 0.2% goes straight to liquidity providers. 0.1% funds the protocol’s development. No hidden fees. No withdrawal charges. No deposit fees. And because TON transactions cost pennies, your total cost to swap $100 might be less than $0.50 in network fees.
Some sites claim STON.fi has 0.00% fees. That’s misleading. Those numbers refer to access to the platform, not actual trades. Every swap you make incurs the 0.3% fee. Compared to centralized exchanges that charge 0.1%-0.4% plus withdrawal fees, STON.fi is competitive. And if you’re swapping between chains, you’re saving hundreds of dollars in bridge fees alone.
Security: No Central Point of Failure
STON.fi is non-custodial. That means your crypto stays in your wallet. No one holds your keys-not the team, not a server, not a third party. The smart contracts are open-source and have been audited by multiple independent firms. Front-running? Minimized. Exploits? Reduced by TON’s asynchronous processing. Even if the STON.fi website goes down, your funds are safe. You can still interact with the protocol through any compatible TON wallet.
Unlike centralized exchanges that have been hacked for billions, STON.fi has no central database to breach. The worst-case scenario? A bug in a smart contract. But audits, community monitoring, and TON’s built-in security features make that unlikely. Experts at GetBlock.io call it one of the most secure AMMs on TON.
Trading Experience: Simple, But Not for Beginners
Using STON.fi is straightforward. Connect your TON wallet-like Tonkeeper, Tonhub, or MyTonWallet. Pick the tokens you want to swap. Enter the amount. Confirm. Done. The interface is clean. No clutter. No confusing tabs. It’s designed for people who already know how wallets and DeFi work.
But if you’ve never used a crypto wallet before? You’ll need to learn first. STON.fi doesn’t explain how to seed a wallet or recover a phrase. It assumes you know the basics. There’s no live chat. No phone support. Just documentation, tutorials, and a Discord channel with minimal moderation. If you get stuck, you’re on your own. That’s fine for experienced users. It’s a problem for newcomers.
Liquidity and Rewards: Earn by Providing Liquidity
Want to earn passive income? Add your tokens to STON.fi’s liquidity pools. You’ll earn a share of the 0.3% swap fees. APRs vary by pair, but some pools offer 10-25% annual returns-higher than most centralized platforms. You can withdraw anytime. No lock-ups.
There’s also staking. Hold STON tokens? Stake them for 3 to 24 months. You’ll get two rewards: ARKENSTON governance tokens and GEMSTON tokens. ARKENSTON is a soulbound NFT-meaning you can’t sell or transfer it. It’s your voting right in the future DAO. GEMSTON is spendable. It’s a clever system: it rewards long-term commitment without letting people dump and run.
Who Is STON.fi For?
STON.fi isn’t for everyone. If you want to buy crypto with a credit card, use leverage, or trade futures-it’s not here. This is spot trading only. No margin. No stop-losses. No fiat on-ramps.
It’s perfect for:
- TON ecosystem users who want fast, cheap swaps
- DeFi natives who hate KYC and centralized control
- Traders who need cross-chain swaps without bridge risks
- Liquidity providers looking for decent APRs on TON pairs
It’s not ideal for:
- Beginners who don’t know how wallets work
- Those who need customer support
- People who want to trade fiat-to-crypto
- Users on non-TON chains who don’t want to bridge assets
Market Position and Traffic
STON.fi isn’t the biggest exchange. It ranks around #179 out of 600+ crypto platforms in traffic. Monthly visits hover around 212,000-most organic. That’s small compared to Binance’s 100 million, but it’s huge for a TON-native DeFi project. The bounce rate is 42%, which is low for DeFi. People stay. They explore. They trade.
Why the modest traffic? Because TON itself is still growing. Most crypto users are still on Ethereum, Solana, or Bitcoin. STON.fi’s future depends on TON’s adoption. If Telegram’s crypto push takes off, STON.fi could explode. Right now, it’s a niche tool for a niche audience. But it’s one of the most polished tools in that niche.
What’s Next? DAO and More Chains
STON.fi isn’t standing still. The team is preparing to launch a DAO. Once live, ARKENSTON holders will vote on fee structures, new token listings, and protocol upgrades. This isn’t just a swap tool anymore-it’s becoming a community-governed platform.
They’re also expanding cross-chain support. More chains mean more users. More users mean deeper liquidity. Better prices. The roadmap hints at integrations with Ethereum, Polygon, and even Bitcoin Layer 2s. If they pull it off, STON.fi could become the go-to cross-chain AMM for TON and beyond.
The Bottom Line
STON.fi delivers exactly what it promises: fast, secure, non-custodial swaps on the TON blockchain. It’s not flashy. It doesn’t have a mobile app yet. It doesn’t have customer service. But it works. Reliably. Cheaply. Without needing your identity.
If you’re already in the TON ecosystem, this is the best place to trade. No other TON-native AMM offers the same combination of speed, cross-chain capability, and low fees. If you’re new to crypto? Learn wallets first. Then come back.
STON.fi isn’t trying to be everything. It’s trying to be the best tool for one thing: swapping tokens without trust. And right now, it’s winning at that.
Does STON.fi require KYC?
No. STON.fi is completely non-custodial and permissionless. You don’t need to provide your name, ID, or even your IP address. All you need is a TON-compatible wallet like Tonkeeper or Tonhub. Your identity stays private.
Can I trade fiat for crypto on STON.fi?
No. STON.fi only supports crypto-to-crypto swaps. You can’t deposit USD, EUR, or any fiat currency. You need to buy crypto elsewhere-like a centralized exchange or peer-to-peer platform-and transfer it to your TON wallet first.
Is STON.fi safe from hacks?
Yes, as long as you protect your wallet. STON.fi’s smart contracts have been audited by reputable firms. The protocol has no central server to hack. Your funds are only at risk if your private keys are compromised. Always use a hardware wallet or a secure software wallet with strong security settings.
What’s the minimum amount I can swap on STON.fi?
The minimum deposit is $1. You can swap as little as $1 worth of crypto. This makes it accessible even for small traders or those testing the platform. Transaction fees on TON are so low that even $1 swaps are cost-effective.
Does STON.fi have a mobile app?
No official mobile app exists yet. STON.fi runs entirely in your browser. You can access it through mobile browsers like Chrome or Safari on your phone, as long as you have a compatible TON wallet installed. The interface is responsive and works well on mobile devices.
How do I earn rewards on STON.fi?
You can earn rewards in two ways: by providing liquidity to trading pools or by staking STON tokens. Liquidity providers earn 0.2% of every swap fee in the pool they contribute to. Stakers earn ARKENSTON (governance) and GEMSTON (spendable) tokens. Rewards compound over time and can be claimed anytime.
What blockchains does STON.fi support?
STON.fi is built on the TON blockchain but enables cross-chain swaps with Ethereum, Polygon, Solana, BSC, and others-all without bridging. It uses HTLC and RFQ to move assets directly between chains. You don’t need to wrap or lock tokens. The protocol handles the conversion securely.
Are there withdrawal limits on STON.fi?
No. Since STON.fi is non-custodial, you control your funds entirely. You can withdraw any amount at any time. There are no daily or monthly limits. The only restriction is the network’s capacity and your wallet’s ability to handle the transaction.
Can I use STON.fi if I’m not on TON?
Yes, but you’ll need to get your assets onto TON first. STON.fi allows cross-chain swaps, so you can send ETH or SOL from another chain and swap them for TON or other tokens. But you must initiate the swap from a TON wallet. You can’t access STON.fi directly from an Ethereum wallet.
What happens if STON.fi shuts down?
Your funds remain safe. STON.fi is just a front-end interface. The smart contracts live on the TON blockchain. Even if the website disappears, you can still interact with the protocol using any compatible TON wallet. You can withdraw your assets, add liquidity, or trade-without needing STON.fi’s website.

December 23, 2025 AT 14:24STON.fi is the real deal if you're tired of centralized exchanges stealing your data. I've swapped TON to USDT, SOL, and even WBTC-all without touching a KYC form. The speed is insane, and the fees are dirt cheap. If you're on TON, this is your default swap tool now.
Also, the fact that you can still interact with the protocol even if the site goes down? That's DeFi done right. No middlemen, no babysitting. Just code and control. -

December 24, 2025 AT 13:47Oh wow, another 'decentralized' platform that thinks 'no KYC' means 'no responsibility.' You're telling me it's fine that a 14-year-old in Nigeria can swap $50k worth of TON to ETH without any oversight? Who's monitoring for money laundering here? The smart contracts? Lol.
And don't get me started on 'atomic swaps'-you think HTLCs are magic? They've been exploited since 2017. TON's 'security' is just a marketing buzzword until someone actually audits the routing logic. I've seen this movie before. It ends with a rug pull and a Discord server gone silent. -

December 25, 2025 AT 16:16‘No customer support’? That’s not a feature, it’s a bug wrapped in a philosophy.
And yet somehow, I’m still using it. 😅 -

December 26, 2025 AT 19:12What fascinates me about STON.fi isn't just the tech-it's the cultural shift. It assumes users are autonomous, literate in crypto, and responsible for their own security. No hand-holding. No corporate safety nets. That’s radical in an era where every app asks for your birthdate, phone number, and pet’s name.
It’s not for beginners. But for those who’ve survived the crypto wars, it’s a quiet revolution. You’re not just swapping tokens-you’re rejecting the surveillance economy. That’s worth more than a 0.3% fee. -

December 27, 2025 AT 19:52STON.fi feels like a hacker’s love letter to freedom-no bouncers at the door, no velvet ropes, no corporate ID scanners. Just a sleek little portal where your keys are your passport.
I swapped TON for Polygon USDC last week and felt like a wizard. No bridge. No waiting. No ‘please verify your identity.’ Just a click, a gas fee less than a coffee, and boom-crypto poetry in motion. TON’s sharding makes this possible, and STON.fi? It’s the conductor.
Also, the GEMSTON staking rewards? Genius. It’s like rewarding patience instead of flipping. ARKENSTON as a soulbound NFT? That’s DAO design with soul. Not just tokens-it’s identity. -

December 28, 2025 AT 12:56STON.fi’s architecture leverages TON’s asynchronous consensus layer to mitigate front-running, a persistent flaw in EVM-based AMMs. The RFQ model, combined with HTLC-based atomic swaps, enables trust-minimized cross-chain liquidity routing without wrapped assets-eliminating counterparty risk inherent in bridge protocols.
Furthermore, the 0.2% LP fee allocation incentivizes deep liquidity pools with minimal impermanent loss exposure due to TON’s low volatility relative to Ethereum. The protocol’s non-custodial nature, coupled with formal verification of core contracts, positions it as a benchmark for secure, permissionless DeFi on emerging L1s. -

December 29, 2025 AT 14:18Y’all are overthinking this. STON.fi is like the coffee shop of crypto-no frills, no waiting, just good stuff. I’ve been using it for months. Swapped my TON for SOL, then back, then some ETH-all under $1 in fees. No drama. No forms. No ‘we’re sorry your funds are frozen.’
If you’re scared of wallets, go learn. This isn’t Robinhood. It’s better.
Also, the GEMSTON rewards? I’ve earned more in 3 months than my savings account in 3 years. 💪 -

December 29, 2025 AT 14:53There’s something almost poetic about a platform that refuses to explain itself. It doesn’t beg for your trust-it earns it by existing. No pop-ups. No tutorials. Just the quiet hum of smart contracts doing their job while you sip your tea.
STON.fi doesn’t cater to the anxious. It doesn’t soothe the confused. It simply *is*. And in a world of over-marketed, over-designed crypto junk, that’s a radical act of integrity.
It’s not a product. It’s a statement: ‘You’re capable. Do it yourself.’ -
Radha Reddy
December 30, 2025 AT 17:07As someone from India, I’ve used dozens of exchanges. STON.fi is the first that didn’t make me feel like a suspect. No document uploads. No video calls. Just connect your wallet and go.
And the cross-chain swaps? I moved USDT from Polygon to TON in under 2 minutes. No bridge, no waiting. I was skeptical, but it worked. Now I use it daily.
Also, the community Discord? Surprisingly helpful. People actually answer questions there. No bots. Just real users helping each other.
