DeDust

DeDust is, alongside STON.fi, one of the two dominant decentralized exchanges on TON, and @dedustBot is the official bot behind DeDust's Telegram presence (linked directly from DeDust's own verified channel). Like any DEX, it lets you swap one TON-based token for another through automated liquidity pools rather than a centralized order book, and it does this without ever taking custody of your assets: you connect a wallet such as Tonkeeper or the built-in Wallet through TON Connect, and every swap is approved and signed in that wallet, not inside DeDust itself.

Typical pool fees sit around 0.25-0.3% of the swapped amount, split between liquidity providers and the protocol's token buyback-and-stake mechanism, and you separately pay TON network gas (usually a small fraction of a TON). That is in line with STON.fi and reasonably transparent, but the underlying risks are the same as any DeFi swap tool: prices move with market liquidity, slippage can change your final amount, and smart contracts, however widely used, are never risk-free. As on any DEX, obscure or newly listed jettons can be scams dressed up to look like a real project, so it is worth checking a token's contract address independently before swapping into it.

For someone who already holds TON in their own wallet and wants to exchange it for another token, DeDust is a reasonable, well-established option alongside STON.fi — just not a place to expect guaranteed returns.
