Tether, the issuer of the USDT stablecoin, is reworking how large-scale crypto mining hardware is built, moving away from conventional, fully assembled rigs toward modular, high-density compute systems designed for flexibility and efficiency.
According to the official announcement, the approach centers on breaking mining infrastructure into core components: compute, power, cooling, and control, rather than packaging them into fixed units. The company says this allows operators to adjust performance, upgrade parts individually, and manage systems more precisely at scale.
Collaboration with hardware and engineering partners
To develop the new systems, Tether is working with Canaan Inc. and ACME Swisstech. The design is built around application-specific hash board modules, which are integrated into Tether’s own control architecture and thermal systems.
This setup replaces the traditional “plug-and-play” mining rig model with a component-based structure, where individual modules can be swapped or upgraded without replacing the entire machine.
Breaking away from monolithic mining rigs
Most mining operations today rely on thousands of standalone units that operate independently. While simple to deploy, that model limits coordination across systems and makes large-scale optimisation difficult.
Tether CEO Paolo Ardoino commented on the development, stating, “Tether is revisioning that concept by deploying modular compute that can be tuned, upgraded, and cooled independently, so we can directly control cost, efficiency, and how these systems perform at scale.”
The company’s architecture separates compute from enclosure and power systems, allowing each layer to be tuned independently. This decoupling is intended to improve system efficiency and reduce downtime, particularly in industrial-scale facilities.
Focus on cooling and performance control
The systems are designed primarily for immersion cooling, a method that submerges hardware in liquid to manage heat more effectively. By aligning hardware design with cooling infrastructure, the company aims to reduce energy overhead and improve hardware longevity.
Operators can also adjust output dynamically based on real-time conditions, rather than being constrained by factory-set configurations typical of standard rigs.
Open-source mining kit expands control layer
Alongside hardware changes, Tether has introduced a Mining Development Kit (MDK), an open-source framework aimed at improving how mining operations are managed across systems.
The MDK is designed as a full-stack framework, combining a JavaScript-based backend SDK with a React-based user interface library. This allows developers to build dashboards and tools that connect directly with mining machines and infrastructure, without depending on proprietary software from hardware vendors.
By bringing different parts of mining operations into a unified system, the framework is intended to give operators a more connected view of their infrastructure and greater control over performance and monitoring.
Industry shift toward custom infrastructure
The modular design reflects a broader trend in crypto mining toward bespoke infrastructure, especially among large operators seeking tighter control over costs and efficiency.
Instead of replacing entire machines during upgrade cycles, component-level changes allow incremental scaling and faster adaptation to evolving hardware and energy demands.
