Abstract: A system for automated account interaction has access to information about asset accounts, and receives transaction indications indicating transactions made by those accounts. The system automatically selects a first transaction indication for a first transaction made using a first asset account, for instance based on location, time, asset quantity, randomization, and/or a trained machine learning model. The system automatically selects a second asset account associated with a second user, for instance based on the second user's location, account balance, randomization, and/or a trained machine learning model. The system automatically transfers an asset quantity from the second asset account to the first asset account, and communicates an indicator indicating transfer completion. The asset quantity can be the quantity corresponding to the first transaction, or a portion thereof.
