Ignition FBTC announced its rebranding as Function, marking a pivotal evolution in institutional Bitcoin yield infrastructure. This transition introduces ƒBTC ($FBTC) as the premier omnichain Bitcoin yield asset, offering institutional participants a secure and sustainable way to generate yield on BTC without compromising its integrity.
Function’s evolution comes at a critical juncture in Bitcoin’s institutional adoption. The shift signals a strategic commitment to expanding Bitcoin’s utility within decentralized finance (DeFi) while ensuring long-term flexibility to support future financial innovations.
ƒBTC ($FBTC), a fully reserved, 1:1 Bitcoin-backed asset, enables institutional participants to access omnichain, structured yield strategies across DeFi lending, staking and liquidity markets while maintaining the security and sovereignty inherent to Bitcoin. ƒBTC embodies a structured and precise approach to Bitcoin’s financial utility, introducing a formulaic standard that optimizes its role in DeFi. Defined by the equation ƒ(BTC) = Liquidity + Composability + Capital Efficiency, this framework ensures that Bitcoin transitions from a static asset to a dynamic financial instrument.
Unlocking Bitcoin’s Financial Potential in DeFi
Despite Bitcoin’s dominance as the world’s most valuable digital asset, its role in DeFi has been historically limited by liquidity fragmentation and a dearth of secure, institutional-grade solutions. ƒBTC addresses this critical gap by transforming BTC into a productive asset while preserving core principles of security and decentralization.
The rebranding strengthens Function’s focus on three foundational pillars:
- Institutional Trust & Security – Purpose-built for institutions, DeFi protocols, and sophisticated DeFi participants, incorporating multi-layer security protocols and comprehensive risk management systems.
- Long-Term Sustainability & Growth – Smart contract architecture that maintains Bitcoin’s 1:1 backing alongside transparent yield strategies and liquidity provisioning. This accelerates ƒBTC’s status as the benchmark for Bitcoin yield, ensuring BTC remains an integral force in DeFi.
- Omnichain & Composable Infrastructure – Seamless integration into major blockchain ecosystems, including Ethereum, Base, Arbitrum, Mantle, and emerging institutional DeFi networks enable fluid capital movement and yield optimization across chains.
“The financialization of Bitcoin demands an infrastructure that upholds its core principles. ƒBTC delivers precisely that – heralding the next phase of Bitcoin’s evolution in DeFi,” said Thomas Chen, CEO at Function. “This rebrand solidifies Bitcoin’s role as a yield-generating institutional asset, allowing BTC to move beyond passive storage and into a new era of programmable value.”
Mantle’s Role in Advancing Bitcoin’s Financialization
As a core contributor, Mantle plays a crucial role in advancing Function’s mission. With Mantle Network’s high-performance Layer 2 infrastructure utilizing zero-knowledge (ZK) validity proofs and a modular blockchain design, ƒBTC benefits from an optimized environment for sustainable Bitcoin yield generation, scaled capital efficiencies and reduced transaction costs for institutional participants.
“At Mantle, we are committed to shaping the future of institutional DeFi,” said Zuki Hong, Growth Lead at Function. “Function’s evolution aligns with our core vision of financializing digital assets in a secure, capital-efficient, and composable manner. Through ƒBTC, we are unlocking new opportunities for institutional Bitcoin liquidity and yield at scale.”
ƒBTC: The Future of Bitcoin as a Yield-Generating Asset
ƒBTC is the first realization of Bitcoin as an institutional yield asset, enabling secure, transparent, and composable Bitcoin yield generation. By leveraging Function’s omnichain framework, ƒBTC enables institutional-grade Bitcoin Yield across DeFi without sacrificing security. Coupled with unparalleled composability and liquidity access, ƒBTC integrates into lending, staking, and structured yield markets across chains, enabling sustainable and programmatic yield designed for long-term capital efficiency.
While ƒBTC remains a core focus, Function is designed to evolve into a broader Bitcoin-centric yield platform. As Bitcoin continues to reshape the future of on-chain finance, the platform’s architecture supports future expansion into structured products and advanced trading strategies, positioning Function’s at the forefront of Bitcoin’s institutional adoption and ultimately unlocking Bitcoin’s full financial potential.
