If this possible to speed up one transaction using other wallet with metamask etc ?
If you are talking about ethereum coin. I dont think it can from other wallet. You can only increased, speed up, cancel, on your own wallet. Of course you can only control this on your own. If this is applicable then too many people already been compromised.
It's so easy to speed up ethereum transaction from other wallet specially if you are using Metamask. You just need to add or increase your gas limit.
Are you sure? From other wallet? I mean not identical?
