Coinomi gives you the ability to manage your UTXOs via labels and 'mark do-not-spend' allowing you more control over your funds. This, by definition, is not an option for coins that do not use the UTXO model, like Ethereum or Solana.
To enter the UTXO control screen, open the wallet of the coin you want to manage, and at the top corner select "... / Show unspent outputs".
Labelling UTXOs:
Once in the UTXO control screen, tap the UTXO which you would like to label and select 'Label UTXO'. You may want to label a UTXO to identify who/where that transaction came from. Once a labeled UTXO is spent, the label disappears and any leftover change from the transaction is a new UTXO (You can then label this UTXO) |  |  |
Marking UTXOs as 'do not spend':
Once in the UTXO control screen, tap the UTXO which you would like to mark and select 'mark do-not-spend'. You may feel the need to mark a UTXO as 'do-not-spend' for many different reasons, the most common being to protect yourself from 'dusting attacks', or to avoid mixing coins that came from different sources. To undo this, tap the UTXO again and choose 'mark as spendable'. Whilst a UTXO is marked as 'do-not-spend' it will NOT count towards the displayed balance in the wallet overview. |  |  |
