If you have submitted a transaction to the blockchain and would like to speed up the time it takes to finalize, you have the ability to do so by increasing the gas price associated with the transaction. To speed up a pending transaction, you'll need to navigate to the MetaMask browser extension and click the "Activity" tab.
Once there, any pending transactions will be listed. You'll see the option to speed up your transaction, which you will need to pay an additional gas fee to submit.
It is important to note that while you have the option to speed up, there is no guarantee that the transaction will confirm. As with any interaction with the blockchain from your wallet, please exercise caution and do your own research before proceeding.
