Most common errors
Transaction errors
When sending or swapping TON, tokens, or NFTs, you might encounter the following errors:
- 'Insufficient funds'
- 'Failed to calculate fee'
- 'Failed to send transaction'
- 'Something went wrong'
- 'An error occurred'
These issues usually happen for two reasons:
- Not enough TON or Battery charges to cover the network fee. Here's what you need to complete a transaction:
- 0.1 TON (~10 Battery charges) to send TON or other tokens
- 0.2 TON (~30 Battery charges) to send HMSTR
- 0.3 TON (~50 Battery charges) to swap TON or tokens
- 0.5 TON (~120 Battery charges) to swap HMSTR
- 0.1 TON (~4 Battery charges) to send NFTs
If you don’t have enough TON, you can always purchase a Battery.
- You’re using an outdated version of Tonkeeper. Older versions of the app may not work properly. Be sure to check for updates in the App Store or Google Play to make sure you have the latest version installed.
Swap error: 'Failed. Increase the slippage tolerance in the swap settings to avoid this error'.
This error happens when the token price changes between when you create the transaction and when it’s executed. For example, the price may have unexpectedly gone up or down.
To fix this, increase the Slippage Tolerance. To do this, tap 'Swap', then click the settings icon in the top left corner and adjust the slippage percentage as needed.
Error 'Emulation error: no response; status code: undefined'
An emulation error may be encountered when confirming a transaction from the external app/website (e.g., a mini app in Telegram). This occurs due to insufficient TON to cover the network fee. Top up your wallet balance and try again.
Error 'Access Denied'
If you encounter an error while confirming a transaction using your PIN code or Face/Touch ID, it may be due to an interruption in the confirmation process (like closing the PIN input window by clicking the "X"). Please attempt to confirm the transaction again.
Error 'BitString Overflow'
You attempted a transaction with a message that is too long. Please reduce the number of characters in the 'Comment' field to avoid this error in the future.
Error 'Invalid Parameters'
This error can occur when confirming transactions in a dApp, such as a mini app within Telegram. To resolve this, reconnect your Tonkeeper wallet in that app and try again. This step should help.
