Your first swap on STON.fi

Once your wallet is set up and funded with Gram (formerly Toncoin), swapping tokens on STON.fi takes about a minute.

Step by step

1. Open app.ston.fi/swap.
2. Click Connect wallet and pick your wallet from the list. On mobile, scan the QR code with your wallet app and approve the connection.
3. Choose the token you want to send (the From token) and the token you want to receive (the To token).
4. Enter the amount. The interface immediately shows the expected output, the swap rate, the blockchain fee, and the price impact.
5. Review the details, then click Swap.
6. Approve the transaction in your wallet. Most swaps complete in a few seconds.
7. Your new tokens appear in your wallet automatically. If they don't show up right away, refreshing your wallet usually fixes it.

Before you confirm

• STON.fi automatically reserves a small amount of Gram from your balance to cover the network fee, so it won't let you swap your entire Gram balance at once — that protects you from being stranded without Gram for the next operation.
• Watch the price impact. A high number means your swap is large relative to the pool's liquidity, which makes the rate worse.
• The slippage tolerance protects you if the price moves between when you click Swap and when the network confirms it. The default is usually fine; only raise it for volatile pairs.
