DeDust

DeDust is an AMM-based DEX on TON and, alongside STON.fi, one of the two primary spot venues in the ecosystem. Architecturally it differs through a factory-based pool model and is considered more native to the jetton standard.

Architectural differences

DeDust uses a factory pattern for pools: instead of holding all liquidity in a single monolithic contract, a factory deploys a dedicated smart contract per pool. Implications:

• Pool isolation. A bug in one pool does not affect others.
• Flexible configuration. Each pool can have its own fee tier and curve type (volatile or stable).
• Permissionless listing. Any project can launch a pool for its jetton without coordination with the DEX team.

DeDust also supports stable pools — a curve optimized for pairs of correlated assets (different stablecoins, TON/LST), which delivers tighter slippage on large size.

Jetton-first design

The DEX is designed around TEP-74 (TON’s jetton standard). Any jetton can be wrapped into a TON/jetton or jetton/jetton pool without wrappers or bridge tokens. This contrasts with EVM ecosystems where wrapped wrappers are often needed for compatibility.

Multi-hop swaps are routed automatically: if there is no direct A → B pool, the router goes through TON as an intermediate.

Integrations

DeDust is integrated deeply into Tonkeeper — one of the wallet’s swap routes draws on DeDust liquidity. It also supports TON Connect, ships as a Telegram Mini App, and exposes a public API for quotes and routing inside third-party dApps.

Additional features include limit orders and an analytics dashboard for LPs with per-position breakdowns of fees and impermanent loss.

Where to use it

Typical use cases:

• Spot swaps TON ↔ jetton, especially larger ones — worth comparing the quote with STON.fi.
• LP provisioning into actively traded TON/jetton pairs.
• Stable swaps between USDT-jetton and other dollar-pegged assets.
• LST/TON pools (tsTON/TON, stTON/TON), often with extra incentives from the LST protocols themselves.

Risks

• Smart-contract risk. Despite factory isolation, the factory contract itself and the router remain shared single points of failure.
• Thin pools. Permissionless listing means many pools carry minimal liquidity; a large swap into one will face severe slippage.
• Scam jettons. As with STON.fi, verify the token contract address before trading — look-alike tickers are common.

There is no universal “better choice” between DeDust and STON.fi: liquidity is distributed, and for any specific pair either DEX can win on price. Experienced users compare quotes on both or rely on aggregators.
