Trezor $ Wallet

Trezor wallets never expose your digital asset information to an insecure environment connected to the internet.

Try out new Trezor Suite features a week before official release when you sign up for the Early Access Program in Application Settings! Since August, we have begun releasing new updates in stages to smaller groups of users, so you may not receive the update prompt until several days after this announcement.

Coin control

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.

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.

One useful application of Coin control is to manage any coins where you have been made to give up identifying documents to acquire them, such as an exchange. Keeping these coins separate through labeling and Coin control can help you stay safe if the exchange one day leaks those documents.

Using Coin control

The best place to learn how to use new features is directly in Trezor Suite. Click on the lightbulb icon in the bottom right of the app and you’ll find the following instructions in the Trezor Suite guide:

• Navigate to the Bitcoin account you want to spend from

• In the Send tab, complete the ‘Address’ and ‘Amount’ fields

• Click the Coin control button to reveal your available UTXOs

• You can then manually select the UTXOs you want to spend

• Once you’re satisfied with your selection, click Review & Send

• Then confirm the transaction on your Trezor device as usual

Remember, your choice of UTXOs must cover at least the amount being sent and the transaction fees. Avoid using low-value ‘dust’ UTXOs of 546 sats or less, as you will overpay in fees.

Take care of your UTXOs

Keeping track of your unspent outputs takes maintenance. Make effective use of the Labeling feature to know where certain outputs have come from.

To benefit from the extra privacy, you may wish to segregate UTXOs from anonymous sources on a separate wallet or behind a passphrase so they do not mix with others.

Users who don’t feel confident using Coin control can look forward to the CoinJoin mixing feature

Other updates

Improved exports for transaction history

Exports of your transaction history have been made more intuitive with localized timestamps, distinct rows for each output, and improved fee units and labels.
