Decentralized Exchanges on TON: Full List 2026

If you hold Toncoin or jettons and want to swap them without moving funds to a centralized exchange, you need a decentralized exchange — a DEX. TON already has a whole spread of them: spot AMM venues, aggregators, perpetual derivatives. This article is the entry point: what a DEX on TON is, how they are built, and a current 2026 list of venues with an honest read on what each is good for.

What a DEX is and how it differs from a regular exchange

A centralized exchange (CEX) is a company: you send it your coins, it holds them in its own accounts, and you trade entries in its database. A DEX works differently. It is a set of smart contracts on the blockchain. You connect a wallet, sign a transaction, and the swap settles directly on-chain — your assets never leave your control until the moment of the trade.

The key differences:

• No sign-up or KYC for a basic swap. Connect a wallet, trade.
• Self-custody. You hold the keys, not the exchange. No risk of an operator freezing your account.
• Transparency. Every trade and pool is visible on-chain.
• The flip side: no support desk, no password recovery, no protection from your own mistakes. Send a token to the wrong place and nobody refunds it.

More on the term itself in the glossary: DEX.

How swaps work: AMM vs order book

Most DEXes on TON use the AMM model — automated market maker. Instead of an order book where buyers and sellers post prices, an AMM holds a liquidity pool: a TON / USDT pair, for example. The price is derived from the ratio of reserves via a formula. When you swap, you trade against the pool, not against another trader.

The basic mechanics are simple:

• Liquidity providers (LPs) deposit both coins into the pool and earn a share of the fees.
• The larger your swap relative to the pool size, the more slippage you face — the price moves against you.
• LPs are exposed to impermanent loss when the asset prices diverge.

A deeper walk-through lives in the glossary: AMM and liquidity pool.

Some venues added concentrated liquidity: an LP can set a price range in which its capital is active, which raises efficiency. That is what TONCO brings. Perpetual DEXes (for leveraged trading) sit closer to an order-book model or use oracles to compute the mark price.

The full list of TON DEXes in 2026

Below are the main venues. We deliberately avoid absolute volume and liquidity numbers: they change daily, so cross-check on DeFiLlama. The “good for” calls are editorial.

STON.fi — the largest spot AMM

One of the oldest and largest spot venues in the ecosystem. A clean interface, a wide selection of jetton pairs, liquidity farming. It has been running for several years and is regarded as one of the most mature venues in the ecosystem. A solid default for a newcomer. Full breakdown in the complete STON.fi guide.

DeDust — the second spot heavyweight

A direct competitor to STON.fi: a native TON protocol with an emphasis on speed and UX and its own pool model (a Vault / Pool architecture). DeDust often has better liquidity on specific pairs. Comparison of the two leaders: STON.fi vs DeDust and where to trade. A standalone DeDust review.

TONCO — concentrated liquidity

The venue that brought a Uniswap-v3-style model to TON: an LP sets a price range, so capital works more efficiently. For a trader that can mean tighter prices on popular pairs; for an LP, higher yield but more active position management. Details in the TONCO review.

swap.coffee — a route aggregator

Not a liquidity pool of its own, but an aggregator: it splits your swap across several DEXes (STON.fi, DeDust, TONCO and others) and assembles the best route. It often delivers a better final price on large trades thanks to lower slippage. See the swap.coffee review and the term DEX aggregator.

Storm Trade — perpetuals

This is no longer spot but derivatives: trading perpetual contracts with leverage. Storm Trade is a notable player in TON’s margin-trading segment. The risks here are fundamentally higher than a plain swap: liquidations, funding, leverage. See Storm Trade perpetuals.

Tradoor — perpetuals inside Telegram

Another perp venue, embedded right inside the Telegram interface. Easy onboarding paired with the same elevated leverage risks. Comparison of the two perp DEXes: Storm Trade vs Tradoor and the Tradoor review.

Fees: what a swap really costs

The cost of a DEX trade on TON has three parts:

• Pool fee — usually around 0.2-0.3% of the swap, paid to liquidity providers. The exact rate depends on the venue and pool.
• TON network gas — a fraction of a cent. TON is cheap, and that is a strength relative to chains with expensive gas.
• Aggregator fee — swap.coffee and similar tools may add a small routing markup, usually offset by a better price.

The main hidden “tax” is slippage on illiquid pairs. On an obscure jetton you can lose several percent purely because the pool is thin, not because of the fee. Always check the expected received amount before confirming.

How to pick a DEX for your goal

• Just swap TON for USDT or a popular jetton — STON.fi or DeDust work fine, or swap.coffee to grab the best route automatically.
• A large amount — an aggregator (swap.coffee) is almost always better because it splits the order and cuts slippage.
• Provide liquidity for yield — weigh the model: a classic AMM is simpler, concentrated liquidity (TONCO) yields more but needs management.
• Leveraged trading — Storm Trade or Tradoor, but only if you understand liquidation mechanics.

Safety: what to watch for

A DEX does not custody your funds, but that does not make it risk-free. The main threats:

1. Scam jettons. Anyone can mint a token with a well-known name. Always verify the contract address (jetton master) against an official source, not the ticker.
2. Phishing sites. Only use a verified link and bookmark it. Fake “STON.fi” results in search are a common trap.
3. Transaction signing. Read what you are actually signing. A request for unlimited access to your balance should raise a flag.
4. Impermanent loss for LPs is not a hack but pool math. Understand what you are signing up for before you add liquidity.
