* outside of this file, which only listens to this to unsubscribe listeners
|
|
* of :rejected and :signed statuses when the inverse status changes. Likely
|
|
* safe to drop.
|
|
* @fires tx:status-update - every time a transaction's status changes we
|
|
* emit this event and pass txId and status. This event is subscribed to in
|
|
* the TransactionController and re-broadcast by the TransactionController.
|
|
* It is used internally within the TransactionController to try and update
|
|
* pending transactions on each new block (from blockTracker). It's also
|
|
* subscribed to in metamask-controller to display a browser notification on
|
|
* confirmed or failed transactions.
|
|
* @fires txMeta.id:finished - When a transaction moves to a finished state
|
|
* this event is emitted, which is used in the TransactionController to pass
|
|
* along details of the transaction to the dapp that suggested them. This
|
|
* pattern is replicated across all of the message managers and can likely
|
|
* be supplemented or replaced by the ApprovalController.
|
|
* @fires updateBadge - When the number of transactions changes in state,
|
|
* the badge in the browser extension bar should be updated to reflect the
|
|
* number of pending transactions. This particular emit doesn't appear to
|
|
* bubble up anywhere that is actually used. TransactionController emits
|
|
* this *anytime the state changes*, so this is probably superfluous.
