If your transaction has been pending for a long time (due a low gas amount), you might want to cancel it or try “speeding it up". Both options require additional gas fees to execute. If the transaction has not broadcasted to the blockchain, it can be manually removed from the wallet's history (see directions toward the bottom of this page).
Please note:
The transaction must be in “Pending” status. If it has completed or failed, it cannot be changed.
Unlike Cancelling or Speeding up, "Removing" a stalled transaction will only remove the transaction from your wallet, not the blockchain.
To cancel or speed up a transaction:
First, tap the “History” button on the home page. Then find the pending transaction you want to speed up or cancel.
Then, tap “Cancel” and confirm the transaction.
In the bottom, you will see the gas amount that will be used to cancel the original transaction.
When the transaction has completed, you will see it in the “History Tab” of your wallet.
If you cancelled, you will see a transaction with a “0” amount, and the funds will be back in the wallet (minus gas fees).
If you chose “speed up”, you will see a brand new transaction that replaced the original.
