STON.fi for Beginners: What It Is and How Swapping Works
If you are new to DeFi, one of the first things you will probably want to understand is how to swap one token for another without using a traditional centralized exchange.
This is where decentralized exchanges (DEXs) like STON.fi come in.
In this guide, I’ll explain what STON.fi is, how a swap works, what slippage means, and some things beginners should check before confirming a transaction.
What is STON.fi?
STON.fi is a decentralized exchange built on The Open Network (TON).
Instead of depositing your assets into a centralized exchange and letting the exchange hold them, you can connect a compatible wallet and swap tokens directly through the decentralized protocol.
The basic idea is simple:
Connect your wallet → Choose the tokens → Enter the amount → Review the swap → Confirm the transaction.
You remain in control of your wallet and approve the transaction yourself.
How does a swap work?
Imagine you have STON tokens and want to swap them for GRAM.
You would generally:
1. Connect your TON-compatible wallet to STON.fi.
2. Select STON as the token you want to sell.
3. Select GRAM as the token you want to receive.
4. Enter the amount you want to swap.
5. Review the estimated amount you will receive.
6. Check the price impact and slippage settings.
7. Confirm the transaction in your wallet.
After the transaction is processed on the network, the received tokens should appear in your wallet.
The exact amount you receive can change because token prices and liquidity can move while your transaction is being processed.
What is slippage?
Slippage is one of the most important concepts for beginners to understand.
The amount shown when you prepare a swap is an estimate. Between the time you submit the transaction and when it is executed, the market price can change.
For example, you might see an estimated amount of 100 GRAM, but the final amount could be slightly different.
Your slippage setting determines how much price movement you are willing to tolerate before the transaction is rejected.
A higher slippage tolerance does not mean you will automatically get a better price.
In fact, setting it unnecessarily high can expose you to a worse execution price.
So before confirming a swap, don't just look at the token amount. Check the slippage and minimum amount you are willing to receive.
What is price impact?
Price impact is another term beginners often confuse with slippage.
Price impact is related to the size of your trade compared with the available liquidity in the pool.
If a pool has limited liquidity and you make a relatively large swap, your trade can move the pool's price more significantly.
This means a large transaction in a low-liquidity pool may receive a less favorable price than a smaller transaction.
That's why liquidity matters when choosing a trading route.
Why use a DEX instead of a CEX?
A centralized exchange (CEX) and a decentralized exchange (DEX) work differently.
With a CEX, you normally deposit your funds into an exchange account and the platform manages the trading process.
With a DEX, you connect your own wallet and interact with the protocol directly.
This gives you more direct control over your assets, but it also means you are responsible for your wallet and transactions.
If you lose access to your wallet or send assets incorrectly, there may not be a customer-support team that can reverse the transaction for you.
Self-custody comes with responsibility.
What should beginners check before swapping?
Before pressing the confirmation button, take a few seconds to check:
- Are you using the correct token?
- Is the token contract/address correct?
- How much are you expected to receive?
- What is the price impact?
- What is your slippage tolerance?
- Do you have enough TON for network fees?
- Are you connected to the official STON.fi interface?
These small checks can prevent expensive mistakes.
Final thoughts
You don't need to understand every part of DeFi before making your first swap.
But you should understand the basics of what you are approving.
STON.fi makes token swapping on TON accessible, but the responsibility of checking the transaction still belongs to the user.
