Fireblocks, the institutional crypto infrastructure platform that processes more than $5 trillion in digital asset transfers annually, has integrated the Stacks Bitcoin Layer 2 network. The move opens Bitcoin DeFi services to more than 2,400 institutional clients who previously had no streamlined way to access them.

The Fireblocks-Stacks integration covers several key capabilities. Institutional clients get custody support for STX tokens, plus the ability to mint and bridge sBTC, the synthetic Bitcoin asset that operates on the Stacks network.

From there, clients can access DeFi protocols built on Stacks, including Hermetica, Zest/Granite, and Bitflow. These protocols span lending, token swaps, and yield generation.

One of Stacks’ selling points for institutional users is speed. The network processes transactions with roughly 5-second block times, compared to Bitcoin’s average of about 10 minutes. For institutions executing complex DeFi strategies, that difference matters.

The integration was announced in early February 2026, with full functionality expected by the end of Q1 2026.
