Unbank
America's longest-running Bitcoin ATM network since 2014 — General Bytes hardware across 45 states
About Unbank
Unbank is a Bitcoin ATM operator founded in 2014, making it one of the longest-running networks in the United States. Operated by Kalbas, Inc. and also known under the brand names Stack ATM and Stack App, Unbank runs approximately 780 machines across 45 states. The dual branding exists for state licensing reasons — customers share the same accounts and login credentials across both brands.
Unbank operates on General Bytes hardware, including both native General Bytes machines and GMKit conversion kits installed on Genmega Universal Kiosks. The network supports buying and selling Bitcoin, Ethereum, Litecoin, Dogecoin, Bitcoin Cash, Tether, Dash, and Zcash. Daily purchase limits go up to $25,000 and sell limits up to $20,000 via PayPal or Venmo.

Elevated regulatory activity - review details
Consent Order for unlicensed money transmission in Connecticut since at least 2019. Kalbas operated a virtual currency kiosk without required money transmission licensure, resulting in consumer funds being used to purchase and transmit virtual currency to third parties. Paid $50,000 civil penalty, $6,375 in back licensing fees, and $17,860 consumer restitution. License application allowed to proceed.
Consent Order for unlicensed money transmission in Ohio. Kalbas, Inc. dba Unbank operated cryptocurrency kiosks in Ohio without ever holding a money transmitter license, in violation of R.C. 1315.02(A). Respondent ceased all Ohio money transmission activity on October 18, 2023 by deactivating all kiosks, and simultaneously applied for an Ohio money transmitter license. Paid $10,000 civil penalty.
Unbank (Kalbas, Inc.) earns an A+ rating on the strength of a 12-year operating history — one of the oldest networks in the industry — and a large footprint across 45 states with ~780 machines. The main blemish: two resolved consent orders for unlicensed money transmission in Ohio (2023, $10,000 penalty) and Connecticut (2024, $50,000 penalty plus $17,860 consumer restitution). Both follow the same pattern — operating ATMs in a state before obtaining the required license. No fraud allegations, no pending litigation, and the company cooperated with regulators in both cases. The repeat pattern across two states is a compliance concern, but both matters are resolved and the penalties were relatively modest.
