Fireblocks and Stacks bring institutional access to Bitcoin DeFi.
New integration enables Fireblocks’ over 2,400 institutional clients to deploy Bitcoin capital in Bitcoin-native DeFi applications on Stacks.
Stacks, the leading Bitcoin layer two enabling Bitcoin-native DeFi has today announced that Fireblocks, the enterprise platform securing more than $5 trillion in digital asset transfers annually, is integrating with Stacks.
The integration will allow Fireblocks’ institutional clients to participate in Bitcoin-denominated DeFi opportunities using the same enterprise-grade infrastructure they already trust for custody, settlement, trading and payments.
Alex Miller, CEO of Stacks Labs, said,
“Institutional interest in Bitcoin yield continues to accelerate, and Stacks is removing the barriers that have kept them sidelined.
“With this integration, Fireblocks clients can access Bitcoin-native DeFi on infrastructure designed to meet institutional security, compliance and operational standards.”
Historically, Bitcoin DeFi has faced constraints making it unsuitable for institutional participation.
Stacks addresses this bottleneck by enabling smart contracts and DApps (decentralized applications) that settle directly to Bitcoin, making institutional-grade Bitcoin DeFi a reality.
Through Fireblocks’ integration with Stacks, institutional users will be able to access a growing suite of Bitcoin-native DeFi use cases, as an extension of existing institutional workflows, including the following.
- Earning Bitcoin-denominated rewards via Dual Stacking, Bitflow and Hermetica
- Lending BTC-backed lending and borrowing with Zest and Granite
In addition to Fireblocks, the Stacks ecosystem is supported by a robust set of institutional integrations, including USDCx via Circle, exchange-grade liquidity through Bitfinex, continuous security programs with Immunefi, seamless wallet connectivity via WalletConnect and more.
Together, these components provide a full infrastructure stack required to transform Bitcoin from idle collateral into a growing digital asset for every portfolio.
The integration is expected to go live in early 2026, unlocking institutional access to productive, Bitcoin-denominated DeFi on Stacks.
About Stacks
Stacks is the leading Bitcoin layer two and the top layer two by developer traction, user activity and market capitalization, helping unlock over $1 trillion in Bitcoin capital held long-term and making BTC a fully programmable, productive asset.
Stacks enables smart contracts and DApps to leverage Bitcoin as a secure, programmable foundation.
With the Nakamoto upgrade activated in October 2024, Stacks achieved near-instant transaction finality and speeds on par with leading layer twos, while retaining the security and irreversibility of Bitcoin layer ones.
The launch of sBTC in December 2024 opened the door for developers and users to use native BTC in smart contracts, DeFi and other Bitcoin-secured applications, including paying gas fees with BTC.
The community-driven Stacks roadmap outlines key priorities for 2025 and beyond, including scaling sBTC capacity, major network upgrades, new DeFi and stablecoin integrations and ongoing improvements to developer tools, security and ecosystem growth.
