Overview
Echo Commerce is an anomalous phenomenon reported within Hollow Metropolis. Abandoned kiosks, vending machines, and terminals activate without an apparent operator or customer.
These machines may print receipts, dispense unfamiliar currency, or offer transactions that no living person remembers making. In a city filled with the remains of interrupted daily life, commerce continues without a clear explanation of who is buying or selling.
Manifestations
Reported outputs include coins, notes, receipts, and digital balances. Their practical use is unclear, although some entities appear to recognize them.
A working screen or a printed receipt does not establish that the transaction follows ordinary commercial rules. The source of the goods, the meaning of the balances, and the identity of any parties involved remain uncertain.
Relationship to the City
Hollow Metropolis contains other market-associated threats, including Broker Wolves and Ticker-Wolves. Their presence provides a reason to investigate unexplained transactions carefully, but does not establish that they create or control Echo Commerce.
The phenomenon's name reflects its resemblance to commercial activity continuing after the people who performed it have vanished. Whether individual incidents are repetitions, active exchanges, or something else has not been confirmed.
Encounter Considerations
The Hollow Metropolis survival guidance warns against accepting printed receipts, coins, or offers from abandoned kiosks without containment procedures.
No universal rule for safely accepting, spending, or discarding these outputs has been established. Apparent value should not be mistaken for understood consequences.
Current Understanding
Echo Commerce is recorded as an anomaly rather than a known merchant or organization. Investigation remains focused on what activates the machines, what their transactions represent, and why certain entities recognize their products.
