# How to accelerate a blocked transaction?

You've minted or bought something but you put too low fee and now your tx (transaction) is blocked in <https://mempool.space>.

Go to *HISTORY* tab, you'll need the **Tx hash**.

**TX hash**: paste the tx number. In the example is d66259930db6677a7b422ab5c0cf86ec2a83841b5ae1b3a41f607ab9713288ec

You can see here that this transaction is already confirmed with the warning message.

If the tx is stuck, when you paste the tx number, **Source** is automatically filled with the address where transaction comes from.

Select your new fee based on mempool current fee.\
For example, your fee were 40 and the current high fee are 80, you have to put 80 if you want a high priority.

Click on *ESTIMATE* to see estimation then *MINT.*

Wait till the transaction is confirmed on <https://mempool.space>.
