How bitcoin transaction fees work

More data, higher fees

Transaction costs are directly related to the amount of data involved in the transaction—not the amount of bitcoin. The more data your transaction includes, the higher the fee you'll need to pay.

Higher fee, faster processing time

If you need to have a transaction processed faster, you’ll need to pay a higher fee. The fee is paid to bitcoin miners to get them to prioritize your transaction over other transactions.

Move bitcoin when fees are low

Get alerts so that you can move bitcoin when fees are low. This will let you move your bitcoin at a lower overall cost. This becomes more important when using higher-security but more data-intensive custody models like multisig.

Understanding bitcoin UTXOs

Bitcoin UTXOs are like “chunks” of bitcoin, and they contribute significantly the data included in a bitcoin transaction.
Alerts are triggered according to mempool.space's low priority setting checked at regular intervals throughout the day. If the state of the mempool has changed since the last check, then emails will be triggered accordingly. Only the change since the last check is logged and used to determine whether an alert is triggered. Preferences can be updated at any time.

There is no personal identifying information required for this service. To maintain as much privacy as possible, you can access this form via Tor (Brave browser's private tab is the easiest way to do this) and create a new, free email just for receiving the alerts.
