I've set up a scheduled (after a specific time) transaction using Parity wallet and the transaction is not showing up in the Transactions view. Just wondering if there is a way to view/cancel/modify scheduled transactions?
Open APPLICATIONS and find the TX QUEUE VIEWER dapp.
It will allow you to review your pending transactions and resubmit (overwrite them).
Note, cancelling is a feature only available on the future releases of 1.7.x branch.
If you want to cancel a scheduled transaction with earlier releases, just stop parity and run it without persistent transaction queue:
I hope this answers your question.
The option listed above, of restarting without persistent transaction queue still works as of 1.7.6
Also, under 'Signer' on the top menu bar, you should be able to view scheduled transactions and edit/cancel them.
