STON.fi: Swap Tokens on TON

Need to swap Toncoin for another token fast, without signing up on a crypto exchange? STON.fi does it right in Telegram: connect a wallet, pick a pair and confirm the swap. 🔁

It is a decentralized exchange (DEX) on the TON network. The bot description promises an instant swap at the best rate. Below is how it works and where the sensitive spots are.

An exchange with no order book

On a regular exchange, buy and sell orders meet in an order book. A DEX differs: trading runs through liquidity pools, which are shared reserves of two tokens.

The price in a pool follows an algorithm based on the ratio of tokens. The more you buy, the further the price moves, and that is called slippage.

• Pool. A reserve of two tokens that swaps draw from.
• Liquidity provider. A person who deposits tokens into a pool and earns a share of the fees.
• Swap. Trading one token for another at the pool's price.

Swapping in five steps

1. Open the Mini App and connect your wallet.
2. Choose the pair: what you give and what you get.
3. Enter the amount and view the expected result.
4. Check the route and fees that the app shows.
5. Confirm the swap in your wallet.

The app shows its calculation before confirmation. Compare the numbers instead of tapping on autopilot. 👀

Two fees that are easy to mix up

The first fee goes to the network: recording the operation on the blockchain needs a little TON on your balance. The app reserves slightly more than required, and anything unused is returned.

The second fee goes to the pool. Its size depends on the pool and is shown in the app. So before confirming, look at the final result, not only the rate.

Routes and cross-chain

The platform develops aggregation: it can look for the best swap path through several liquidity sources. Swaps between different networks without a separate exchange account are also advertised.

Risks that get less airtime than they should

• Fake tokens. Anyone can create a token with a lookalike name. Check the contract address.
• Thin liquidity. In a small pool the price jumps, and selling back can be impossible.
• Slippage. The final price may differ from the expected one.
• Volatility. A token price can fall to zero.
• Phishing. Connect your wallet only on a verified page.

Never hand over your recovery phrase. No service, support included, should ask for it. 🔐

A useful habit: before a large swap, make a test operation with a minimal amount. You will see real fees and timing, and confirm that the token arrives at the right address.

Keep a little TON in reserve for fees. Without it even a reverse swap cannot be made, and tokens get stuck in the wallet.

Who it is for and what next

STON.fi suits people who already have a wallet and a bit of experience. Beginners should start with a small amount to walk the whole path from swap to balance check.
