Most common errors
Transaction errors
If you're using an outdated version of Tonkeeper or don’t have enough TON or Battery charges to cover network fees, you might see one of these errors when trying to send, swap tokens, or transfer NFTs:
- 'Failed to send transaction' (or 'Error!')
- 'Something went wrong'
- 'An error occurred'
- 'Insufficient funds'
- 'Failed to calculate fee'
To avoid these issues, make sure you’ve updated Tonkeeper to the latest version from the App Store or Google Play. Also, check that you have enough TON or Battery charges for network fees:
- 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.
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 '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.
