Tonco Review 2026: A Concentrated Liquidity DEX on TON

Tonco is a decentralized exchange on the TON blockchain. It lets users swap tokens and lets liquidity providers deposit token pairs into pools to earn trading fees. Its defining feature is concentrated liquidity, where providers select a price range for their capital instead of spreading it across all prices.

The project is reached through a Telegram Mini App, which places its trading interface inside the Telegram messaging app. Public reporting shows promotions and points programs tied to liquidity provision, which suggests the project relies on user incentives to attract capital.

Tonco's status is in transition. Its v1 pools were paused for adding liquidity and swaps during a v2 upgrade, so users should check which version their positions sit in. A 2024 announcement also described the project as a DEX plus prediction market, a feature that is outside the core exchange and carries its own risks.

Tonco is a decentralized exchange, or DEX. Instead of matching buyers and sellers in an order book, it uses liquidity pools. Liquidity providers deposit a pair of tokens into a pool, and traders swap one token for the other against that pool. The price is set by the ratio of tokens in the pool.

Tonco uses concentrated liquidity. A provider chooses a price range and places capital only inside it. Because more capital sits near the current price, trades can execute with less slippage, and providers in the active range can earn a larger share of fees than they would across the full price curve. The trade-off is that a position stops earning when the price leaves its range.

The exchange runs on TON and can be reached through a Telegram Mini App. Third-party write-ups describe its v1 pools as having adjustable fees, and the project has moved to a v2 version, during which adding liquidity and swaps were paused for v1 pools.

Tonco does not publish specific fee amounts in the sources behind this review. One third-party write-up reports that pool fees adjust to the assets being traded, so the rate can differ between pairs.

Fee rates, price impact and migration costs appear on the swap and pool screens at the moment of each transaction. Compare the quoted output and fee before confirming, because the rate on a given pair can change.

Tonco does not publish audit reports or a named auditor in the sources behind this review. Users should treat that gap as a reason for caution, not as proof of a problem.

As a decentralized exchange, trades run through smart contracts from the user's own wallet. That removes custody risk by the project but leaves smart-contract risk, meaning a bug or exploit in the code could cause loss. The v1 to v2 migration adds another layer, since moving liquidity between versions involves transactions that can fail or cost fees.

No incidents, regulatory actions or licensing details are stated in the material behind this review. The prediction market feature, if active, is betting-style and is restricted to adults in many places. Check that it is legal where you live, use it only if you are 18 or older, and keep to limits you set in advance.

Tonco is aimed at active TON users who are comfortable with DEX trading and liquidity provision. It suits people who will read price ranges, track positions and accept that funds outside a range stop earning. Casual users who want simple fixed-price trading may find a standard AMM pool easier to understand.
