Cancel a transaction that has not been pushed via Mist

Question

I submitted a transaction via Mist with the fee slider at the leftmost position. Nothing happened for a day now, so I suspect that the displayed gas price has been to small, although Mist told me that the transaction is likely to be executed in a few minutes.

I searched the internet on how to cancel a transaction and found that in principle there is no way.

However, the transaction does not even show up on etherscan yet, so I suspect that it might not even have been published(?). If it is so, is there a way to stop Mist from doing so?

I also found that you can send another transaction with a higher gas price but the same nonce such that only the latter transaction is executed. I could send a zero-valued transaction to myself with the same nonce. Is there a possibility in Mist to find out the Nonce of the displayed transaction and to send another transaction with the same nonce?

Edit: The linked "possible duplicate" does not explain how to get the nonce from a transaction in Mist and submit a new transaction with the same nonce.

Answer 1

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.

You can't cancel a tx, normaly it will been eareased in 2 days beacause it was stuck to many time in the mempool. (If you have put the slider left your tx will never pass)

And try to find it here : https://etherscan.io/txsPending it is all the tx not passed because they are to young or because they have a to low gas price.

And why mist print you it will pass in few minutes ? Because your node havn't all the mempool, (mist didn't know all the tx, it saw just a litle part of them and it think: "there is only these tx ? so a litle gas will pass". But why you didn't know all the tx ? Probably because your node are in desktop and your ISP box havn't upnp so your node isn't visible from outside so you can go on other node for download blocks, you can send your tx to other node but other can't pull you block and tx, so you never receive other tx except if your wallet do this by them self, but they do that not very often (close to never))
