Bidask

Bidask is a smaller but technically interesting DEX on TON. While STON.fi and DeDust run the classic constant-product model, Bidask leans on concentrated liquidity in the style of Uniswap v3 — LPs choose the price range in which their capital is active.

What concentrated liquidity means

In a classical AMM, LP capital is spread across the full price range from zero to infinity. Most of it sits idle in regions where trades almost never happen.

Concentrated liquidity (CLMM) lets an LP say “I want my TON and USDT to be active only between 5 and 7 USDT per TON”. Capital in that narrow band collects many times more fees per dollar deposited than in a vanilla pool — but as soon as price moves outside the range, the position stops earning.

Why it suits experienced LPs

CLMM is powerful but demanding:

• Active management. When price exits the chosen range, the position converts entirely into one asset and stops collecting fees. LPs need to monitor markets and re-set ranges.
• Higher impermanent loss. Narrow ranges amplify IL during volatility.
• Harder to forecast yield. There is no clean APR; returns depend on range choice and realized price action.

The typical Bidask user is not “deposit and forget” but a trader-LP who understands the mechanics.

Position in the ecosystem

By volume Bidask is noticeably smaller than STON.fi and DeDust, and its pool coverage is more limited (primarily TON, stablecoins, and select LSTs). For the pairs it does cover, however, concentrated liquidity can deliver materially tighter slippage on larger swaps — so DEX aggregators and arbitrageurs include Bidask in their routes.

Use cases

• Active LPs willing to manage ranges and rebalance.
• Large swaps in pairs with deep concentrated liquidity — sometimes a better price than the main AMMs offer.
• Professional market-making. Strategies that approximate a central limit order book by placing narrow CLMM positions.

Risks

• Smart-contract risk. CLMM contracts are more complex than vanilla xy=k pools, which expands the attack surface.
• Out-of-range risk. When price leaves your range, the position converts fully into the “cheap” asset. On strong reversals, you can effectively buy a falling token and watch it drop further.
• Low liquidity outside the core pairs. For most jettons, STON.fi or DeDust will still be the better venue.

Bidask is a niche but useful slice of TON DeFi — best for users who can compute the expected APR on a given range and are willing to spend attention on capital efficiency.
