Catenaa, Monday, February 09, 2026-Fireblocks and Stacks have announced an integration designed to give institutional investors direct access to Bitcoin-denominated decentralized finance, expanding the use of Bitcoin beyond custody and trading into onchain yield and lending.
Under the integration, Fireblocks’ more than 2,400 institutional clients will be able to deploy Bitcoin into DeFi applications built on the Stacks network while continuing to use Fireblocks’ existing infrastructure for custody, settlement, trading and payments. The companies said the offering targets institutions seeking Bitcoin yield within familiar operational and compliance frameworks.
Bitcoin DeFi has historically seen limited institutional participation due to technical and security constraints. Stacks addresses those limits by enabling smart contracts and decentralized applications that settle directly to the Bitcoin blockchain, allowing Bitcoin to be used productively without leaving its native security model.
Through the new setup, Fireblocks clients will gain access to Bitcoin-native earning products, including yield strategies tied to stacking and decentralized exchanges, as well as BTC-backed lending and borrowing services. These activities are designed to integrate into existing institutional workflows rather than requiring new custody or operational systems.
The Stacks ecosystem already includes integrations with stablecoin issuers, liquidity providers and security platforms, creating a broader infrastructure stack aimed at professional market participants. The companies said the combined tools are intended to turn Bitcoin from largely idle collateral into an actively deployed asset within portfolios.
