[Ethereum] Mist, transaction “couldn’t be successfully executed”

misttransactionswallets

For some reason I can't send transactions from my Mist wallet. I'm running the newest version (0.8.7).

When I send a transaction, after a couple of minutes I get the message that the transaction "couldn't be successfully executed". It never gets any confirmations.

I tried it once with the lowest possible fee, once with the standard fee and once with the maximum fee, but all failed after a couple of minutes.

Can someone explain why?

Update your system time to sync with an internet time server

In Windows: 1)Double click on the date&time displayed on the taskbar on the lower right hand corner of your screen 2)Click "Change Date and Time Settings" 3)Click on "Internet Time" tab 4)Check the box "Synchronize with an internet time server" 5)Chose a server (e.g. time.nist.gov) from the drop-down 6)Click "Update now" button 7)Re-launch Mist and let it finish syncing your node with the block-chain data from its peers before trying to send your transaction again

OS X: sudo ntpdate -u time.apple.com

Linux see: https://unix.stackexchange.com/questions/79112/how-do-i-set-time-and-date-from-the-internet

I had the same issue, so I tried Parity, which threw an error: "Your clock is not in sync. Detected difference is too big for the protocol to work: -2254ms. Synchronize your clock."

When I did the above, I was able to re-launch Mist, Parity, and the Ethereum Wallet client and my transactions could go through with any of those (after finishing syncing the node with the block-chain data from network peers)

This is normally an error detected by the eth.estimateGas(...) function call, where this call returns back a result that gasUsed==gas as you have found in your answer to How to estimate gas for a function without any input parameter?.

You can see the Mist error message at mist.en.i18n.json#L193:

"estimatedGasError": "It seems this transaction will fail. If you submit it, it may consume all the gas you send.",

And this estimatedGasError error message is displayed by the code at sendTransactionConfirmation.html#L56-L66:

{{#if transactionInvalid}}
    <p class="info dapp-error"> {{{i18n "mist.popupWindows.sendTransactionConfirmation.estimatedGasError"}}} </p>
{{else}}
...
{{/if}}

The transactionInvalid status is computed by the code at sendTransactionConfirmation.js#L259-L263:

'transactionInvalid': function() {
    return TemplateVar.get('estimatedGas') == 'invalid' 
            || TemplateVar.get('estimatedGas') == 0
            || typeof TemplateVar.get('estimatedGas') == 'undefined';
}

You may want to check your smart contract code to work out why the an error is being thrown.

[Ethereum] Cancel a transaction that has not been pushed via Mist

I do not regularly use Mist myself, but I believe that its wallet is the same as https://wallet.ethereum.org/, which I do use quite often. In which case, simply repost your transaction using a higher fee. Until it confirms on the blockchain, Mist should use the same nonce as the original transaction.

To determine the best gas price to use next time, I would recommend using https://ethgasstation.info/ and check the Gas Price SafeLow number.
