As the Ethereum network becomes congested and the number of on-chain transactions skyrockets, the average gas price increases, making the original gas price lower than the current average level and transactions cannot be confirmed for a long time. Also, transactions initiated by senders cannot be confirmed as well. In this case, ViaWallet ETH Transaction Acceleration and Cancellation can help. The following tutorial is for canceling ETH transactions.
Step 1: Go to the ETH asset page that displays ETH transaction history. If you want to accelerate the confirmation of a "packing" transaction, tap the button "Cancel Tx".
Step 2: The system will calculate a suitable transaction fee for you. The fee will be used as the on-chain miner's fee, which is equivalent to initiating a new transaction with a transfer amount of 0, and this transaction will overwrite the previous transaction (i.e., the one that needs to be canceled), so as to achieve the effect of canceling the transaction. Click the "Confirm" button.
Step 3: Double check the transaction information is correct, and tap "Confirm".
Step 4: The transaction cancellation is completed. Wait for a moment and you will see the successful status of the transaction.
Step 5: Back to the currency page, you can see that the transaction has been canceled successfully.
