Feature Request: “Coin Control” or “UTXO Management”

[allodial]

PROBLEM:

Currently there is no way to see, organize, select and spend specific UTXO’s in the iOS app. This often causes spend transactions to use multiple UTXOs when the user intention is not to do that. Without this, transaction privacy is not possible to control in the app.

REQUESTED SOLUTION:

1. Add “Coin control” as a prominent option near the “Send” and “Receive” buttons, perhaps as an option under the “+” button

2. In the Coin Control view, list each UTXO with:

• sats / BTC value
• fiat value
• address
• “change” label if its a change address
• “add label” button (allows typing a custom label)
• custom label (it it exists)
• ”freeze” and “unfreeze” toggle button (ie prevents/allows the UTXO for spending)
• date/time when UTXO created

3. In the Coin Control view, allow the user to:

• sort the list of UTXOs by value, date, frozen status with ascending and descending sort options
• add or edit a custom label on a UTXO
• freeze and unfreeze a UTXO
• select 1, select multiple or “select all” non-frozen UTXOs
• tap “send” to proceed to the send view where all or a subset of the selected UTXOs may be spent
• tap “combine” to proceed to a pre-filled send view (ie prefill the receiving address from own wallet and prefill the amount as the sum of all UTXOs)… fees should be subtracted from the selected UTXOs rather than taken from non-selected UTXOs
