MEW FAQ articles are based on real user questions, edited for privacy, clarity, and flow.
I sent a transaction hours ago, and it still hasn't gone through. How long does it take? Should I await? Tin can I abolish information technology? Tin I even so utilise my wallet for other transactions?
What a great question! Although such delays don't happen very often, they are
frustrating when they exercise. What if it'southward an urgent transfer? Can you lot use your wallet for other transactions while one is pending? Is the internet down? Is MEW cleaved? Is the blockchain broken?
Ordinarily, transactions sent via MEW will betoken 'Success' in Notifications within minutes, if non seconds, of confirming. Initially you volition see that the transaction is 'Processing', and if that status isn't changing for a long time, you lot may wonder what has gone wrong.
The first affair to exercise is bank check transaction status with an Ethereum block explorer like Etherscan, where it is probable to show as 'Pending'. This means the transaction has not been picked up past miners yet. Your transaction will go through, and show 'Success' status on the cake explorer, simply when miners option it from the pool of all signed transactions, put it into a new block, and add it to the blockchain.
the transaction will be picked upwardly depends more often than not on 2 factors – network congestion and the transaction fee, which in turn is adamant past gas limit and gas toll. Because miners receive the gas fees for the trouble of maintaining and growing the blockchain, it's in their interest to pick up transactions with the highest fees starting time.
With increased network congestion, gas fees go upwardly throughout the Ethereum blockchain, and it takes a little more than ETH to become to the front end of the line. (For a more detailed wait at the transaction journey and the adding of the fee, run across our explanation of how Ethereum gas works.)
So, what can y'all exercise to brand sure a transaction doesn't get stuck, and what activity tin can you lot take if it does?
Many wallets, including MEW, set the transaction fee for you automatically, simply the automated calculation does depend on your selection of Transaction Speed. In MEW web, you tin accommodate this by clicking 'Edit' across from 'Transaction Fee' on the Send Transaction page, which volition open the Settings window. Yous tin also find Settings under the identicon in the upper correct corner of the screen.
In MEW wallet app, y'all can also select the desired speed setting for every transaction by clicking on the Fee dropdown and choosing Economy, Regular, or Fast. Just like in MEW spider web, the fees will arrange according to current network conditions.
of the time, the Economy setting works just fine. Network conditions tin can change speedily though, and gas prices that were slap-up a few hours agone may become insufficient at a subsequently moment (over again, these are
cases we are talking about). That'south why, to prevent transactions from suddenly getting stuck during high network congestion, it's best to keep your Transaction Speed set to Regular or Fast.
How practise you know whether the network is congested and what transaction fees are good right now? A blockchain explorer is, once again, the answer. (In fact, block explorers are the respond to a lot of adept crypto questions.)
On Etherscan, y'all can detect a chart showing Daily Network Utilization. The higher the percentage, the busier the network, the higher the gas prices. To see what kind of gas prices are leading to successful transactions at the moment, EthGasStation or Ethereum Gas Tracker may help. These pages are ever being updated, though you lot may have to keep refreshing the folio. Viewing the electric current rates before sending the transaction can help you adjust the gas toll to ensure the transaction goes through without issues. Remember, though, that MEW will set the gas toll for y'all automatically, and y'all should only accommodate gas settings manually if you know what you're doing and take a specific goal in mind.
If the transaction gets stuck in pending limbo despite all preventative measures, you may demand to simply wait it out. When the entire Ethereum network is clogged and delays are experienced across the board, there might be nothing you tin can exercise to button the transaction through – that is, until blockchains calibration to greater capacities and speeds, which is something all of the states are looking forward to!
Otherwise, at that place are a few things you can try, but keep in mind that they are not guaranteed to work and
none of this ways that you lot can cancel a blockchain transaction whenever you wish. All transactions to the blockchain are nevertheless final and, at the adventure of repeating ourselves, cases when they get stuck awaiting indefinitely are very rare...
Sometimes, but trying to send the transaction again will go it to go through. If network congestion has gone down since the last fourth dimension you lot tried, the same gas cost might at present work successfully. The other options are to endeavor canceling or replacing the transaction, which essentially means either sending a 0 ETH transaction to yourself or attempt the aforementioned transaction again, but with a much higher gas price.
For MEW web, y'all can find out more near checking transaction status and canceling/replacing transactions on our Aid Folio, merely think – these are techniques all-time tried by experienced users.
In MEW wallet app, just click on the awaiting transaction to run across the options for speeding upwards and canceling. Make sure that you are selecting a higher gas fee than the first time, otherwise they process may not piece of work.
