Coin control is an advanced feature that allows you to specify which UTXOs you want to spend in a transaction. Used properly, it can improve privacy, though we only recommend that you use it once you are familiar with the principles.

How it works

Your Bitcoin wallet balance is made up of many unspent transaction outputs (UTXOs) from incoming transactions or leftover change from outgoing payments.

When making a payment, your wallet may need to spend the contents of several UTXOs to make up the total purchase amount. Without Coin control, your wallet automatically chooses which to spend, favoring the cheapest option.

Each of those UTXOs has its own lineage of previous transactions, some of which may offer hints that reveal information about you that you don’t want to share. To protect your privacy, you can enable Coin control and specify which particular UTXOs to use in a transaction.
