How to speed up transaction confirmation?

How do I change the recipient / transaction amount? How do I cancel a transaction?

If the transaction is in mempool (not yet included in the block), then it can be "replaced". To do this, you need to send a transaction with a price higher than in the transaction being replaced, but with the same .
To speed up the confirmation of the transaction - just increase the gas price to current actual value.

In your account, on the "Sending" tab, find the request with the required txid (you can use filter) and click the green button with gears. A window with sending parameters will open. Here you can change the "Recipient Address", "Token" or "Amount". Click on the "Manual" tab. Here you can change the "Gas Price" and "Gas Limit".
To replace a transaction, DO NOT CHANGE Nonce! Nonce must be the SAME as in the replaced transaction! Always set the gas price MORE than the previous value!

Save changes and restart processing the request with the blue button with arrows.
When the new transaction is confirmed, the old transaction will have the status "Dropped & Replaced"
