STON.fi v2: What It Is, How It Works, and Why It Matters for DeFi on TON

When you trade crypto on the TON blockchain, a fast, scalable, and low-fee blockchain built by the Telegram team. Also known as The Open Network, it's designed for real-world use—like sending payments, running apps, and trading tokens without waiting minutes or paying $50 in gas. That’s where STON.fi v2, a decentralized exchange built specifically for the TON network. It’s not just another DEX—it’s the most used trading platform on TON, handling millions in daily volume with near-instant trades and fees under a penny. STON.fi v2 lets you swap tokens like JETTON, USDT, and even NFTs without a wallet connection to a centralized exchange. No KYC. No middlemen. Just direct peer-to-peer swaps powered by smart contracts.

What makes STON.fi v2 stand out isn’t just speed—it’s how it’s built. Unlike older DEXs that rely on complex liquidity pools and high slippage, STON.fi v2 uses a custom automated market maker (AMM) optimized for TON’s architecture. It supports JETTON tokens, a standard for fungible tokens on TON, similar to ERC-20 on Ethereum. Also known as TON tokens, they’re the backbone of most DeFi activity on the network. You can add liquidity, earn fees, and even stake your position—all within the same interface. And because TON processes transactions in seconds, your trades settle before you finish reading this sentence. It’s not theory. It’s what real users do every day.

STON.fi v2 isn’t just for traders. Developers use it to launch new tokens. Communities use it to distribute rewards. Even small projects without big marketing budgets rely on it because it’s free to list and easy to integrate. That’s why you’ll find it linked in Telegram groups, crypto newsletters, and wallet apps like Tonkeeper and Tonhub. It’s the default DEX for TON—not because it was forced, but because it just works.

But it’s not perfect. There’s no fiat on-ramp. You need to buy TON first. And while the interface is clean, it’s not beginner-friendly if you’ve never touched a wallet before. Still, if you’re already in the TON ecosystem, STON.fi v2 is the only tool you need to trade, earn, and move value without asking permission.

Below, you’ll find real reviews, comparisons, and breakdowns of projects built on or connected to STON.fi v2. Some are active. Some are dead. All are real. You’ll see what works, what doesn’t, and how to avoid the traps that come with fast-moving DeFi on TON.
