Troubleshooting Tips and Best Practices for Smooth Swaps

If it’s your first time using a DeFi protocol on Telegram blockchain, here are some best practices that will help avoid common pitfalls:

Top Tips for Successful Swaps on STON.fi

  • STON.fi wallet interface with TON balance
    Ensure Sufficient TON Balance for Fees: Always keep at least 0.4 TON in your wallet to cover transaction fees and the blockchain's reserved amount. Actual swap fees are typically 0.05–0.08 TON, but having extra ensures smooth processing.
  • STON.fi token selection screen
    Double-Check Token Addresses and Symbols: Before confirming your swap, verify you’ve selected the correct token addresses and symbols. This helps prevent accidental swaps for scam tokens or incorrect assets.
  • STON.fi slippage tolerance settings
    Review Slippage Tolerance Settings: Check and adjust your slippage tolerance in the swap interface. Lower slippage reduces the risk of unexpected price changes but may cause failed transactions in volatile markets.
  • STON.fi swap review screen with price impact
    Check Exchange Rates and Price Impact: Carefully review the exchange rate and price impact shown before swapping. High price impact may indicate low liquidity or large trade size, potentially leading to less favorable rates.
  • STON.fi connect wallet prompt
    Confirm Wallet Connection and Permissions: Ensure your TON-compatible wallet (such as Tonkeeper or TON Wallet) is properly connected and authorized to interact with STON.fi before executing swaps.
  • STON.fi transaction confirmation screen
    Monitor Transaction Confirmation: After initiating the swap, wait for on-chain confirmation. Swapped tokens should appear in your wallet within seconds on the TON blockchain.

If a transaction fails or stalls, check that your wallet is connected correctly and that you have enough TON not just for swaps but also network fees. Double-check all amounts before confirming - especially if swapping less liquid tokens where price impact can be higher.

StonFi’s transparent interface is designed to keep users in control at every step. Before confirming any swap, take a moment to review the exchange rate, expected output, and network fees. This final check can prevent costly mistakes, especially when exploring new tokens or larger trades. If you’re swapping assets with lower liquidity, consider adjusting your slippage tolerance or splitting your trade into smaller increments for better execution.

The utility of StonFi TON extends well beyond basic token swaps. For those looking to deepen their involvement in the Telegram blockchain DeFi ecosystem, StonFi also offers:

If you’re new to DeFi or coming from more traditional exchanges, this model may feel different but offers significant advantages: full transparency, reduced counterparty risk, and instant settlement. Always ensure you’re using the official STON.fi application, and never share your wallet seed phrase with anyone.
