Since cryptocurrency is, by definition, digital, UTXO's function the same way dollar bills do with fiat currency. If your physical wallet carries banknotes, then your digital wallet carries UTXOs.
What is a UTXO, and how does it apply to your Beam coins?
UXTO (unspent transaction value).
UTXO represents the amount of cryptocurrency remaining after each transaction. The "output" for each UXTO creates a new "input" for new transactions.
Your Beam wallet automatically selects the UTXO for each transaction.
Your Beam wallet automatically minimizes the output value you receive by automatically selecting the UTXO for each transaction.
You will not be able to send or spend your UTXOs until each transaction is complete.
Access your wallet UTXO's by tapping menu
in your Beam mobile wallet.
