I think this will be easy now to implement with the recent changes.
We should add a toast trigger to the UseEffect listeners in DataManager.
Listen for a txnType; at the same time as handing it in to get added to TxnArray; trigger a toast with very basic info and a spinner
Use the 'status' prop from the txnReceipt object to show either a tick or cross on txn confirmation
Fade it away after maybe 5-10 seconds?
Would be cool if it had a slide animation towards the RecentTxns drawer as it fades to signal to the user that they can find the txn in the history there
