Tether, Canaan and ACME debut modular Bitcoin rigs

Tether announced plans for modular Bitcoin mining rigs developed with Nasdaq-listed Canaan Inc. and ACME Swisstech. The design separates compute hardware from power and cooling systems.

By decoupling compute, power delivery and cooling, operators can upgrade or replace ASIC boards, power modules or cooling units independently without scrapping entire machines, the partners wrote in a joint statement.

Tether and its partners described the architecture as an industrial-scale alternative to sealed, fixed mining units, aimed at large mining operations that require flexible upgrade paths and tighter control of operating costs.

Paolo Ardoino, Tether’s CEO, wrote that “Most mining infrastructure is still built as sealed, fixed units, which makes it expensive to scale and inefficient to run.”

Giv Zanganeh, ACME Swisstech president, described the project as an industrial co-design targeting large-scale operators and wrote that the systems would differ from retail plug-and-play products.

Canaan, which supplies ASIC chips and mining hardware, will contribute chip and rig design expertise to the program.

Tether has published an open-source Mining OS and released a Mining SDK on Monday to standardize integration with hardware and management tools. The partners have not provided release dates, pricing, technical specifications or images for the planned rigs.

The announcement comes as Bitcoin’s price has fallen roughly 40% from last year’s record high. Some mining companies are shifting capacity to AI compute and other data-center services; Keel Infrastructure sold a mining site in Paraguay for about $13 million, and Hive Digital Technologies completed a $115 million private offering.

The partners noted similarities with other modular mining efforts, including Block’s Proto Rig introduced last year, and emphasized the design’s focus on industrial deployments for large miners.

No manufacturing timelines or pricing details were disclosed. The companies stated the program targets large-scale operations and intends to pair Canaan’s ASIC work with ACME’s thermal and mechanical engineering while integrating with Tether’s mining software tools.
