Based on the search results, I can now provide a comprehensive overview of Function FBTC. Note that there are two different assets using the FBTC ticker: Function FBTC (a cryptocurrency token) and Fidelity Wise Origin Bitcoin Fund (a Bitcoin ETF). This overview focuses on Function FBTC, the cryptocurrency token.
Function FBTC (FBTC) Cryptocurrency Overview
Core Technology and Blockchain Architecture
Function, previously known as Ignition, is a decentralized protocol that enables seamless BTC integration across multiple blockchain networks through FBTC. FBTC represents the first omnichain Bitcoin yield asset, enabling BTC holders to participate in structured, risk-managed and programmatic yield strategies.
FBTC is fully backed on a 1:1 basis with BTC, Bitcoin Reserve Address List is public and can be verified at any time. FBTC combines the security of Bitcoin reserves with the flexibility of smart contracts, creating a secure and efficient bridge between the Bitcoin network and modern DeFi protocols.
FBTC employs a TSS network to conduct minting and redemption to enshrine decentralization in its operations. FBTC ensures that users' assets are managed with adequate authority through Multi-party computation, removing the possibility of a single point of failure. This decentralized approach reduces the risks usually associated with centralized custody solutions.
$FBTC will adhere to the ERC-20 token standard, allowing it to be used across the broader Ethereum ecosystem. Direct minting and burning occurs across 8+ major ecosystems, including Ethereum, Mantle, and Arbitrum.
Primary Use Cases and Real-World Applications
Function is building the financial infrastructure that makes Bitcoin productive, unlocking yield, liquidity, and capital efficiency for holders across DeFi and traditional finance. The primary purpose of FBTC is to bring native Bitcoin liquidity into DeFi. Enabling Bitcoin holders to access a wide range of yield generating strategies, without having to sell their BTC.
By enabling functionality across various blockchain networks—including Ethereum, the Mantle Network, and BNB Smart Chain—$FBTC allows users to tap into an array of yield-generating strategies. DeFi opportunities for $FBTC include funding rate arbitrage, lending and borrowing, restaking rewards, yield farming, token swapping, and liquidity pools.
Function is positioning FBTC as the gateway for institutions and corporate treasuries to productively deploy bitcoin while maintaining full custodial control and 1:1 asset backing.
Founding Team, Key Developers, and Project History
Function, previously known as Ignition FBTC, is set to announce its official rebrand on February 13, 2025. Thomas Chen joins as CEO of Function, leading the development of Function 𝑓BTC (FBTC). Previously serving as Managing Director and Global Head of Sales at BitGo, he helped scale the regulated digital asset custodian to over $100B in assets.
The identity of the creator behind Ignition and $FBTC remains undisclosed, as specific information regarding an individual or collective progenitor has not been firmly established. Nevertheless, Ignition operates as an incubator for $FBTC, orchestrating its development and growth.
In August 2023, FBTC conducted its first major promotion, "Ignition Sparkle." This promotion laid the groundwork for its airdrop and gave FBTC the publicity it needed to build a community. By the beginning of 2024, FBTC had reached a transaction volume of $100 million.
Tokenomics: Supply, Distribution, and Mechanics
Based on current market data, with a circulating supply of 11 Thousand FBTC, Function FBTC is valued at a market cap of BTC10,830.2867. The fully diluted valuation (FDV) of Function FBTC (FBTC) is BTC10,830.2867. This is a statistical representation of the maximum market cap, assuming total number of 11 Thousand ETH tokens are in circulation today.
When Function Bitcoin (FBTC) launched, it implemented a fair distribution model to ensure widespread accessibility. This distribution model was designed to prevent concentration of FBTC tokens while incentivizing long-term participation and development of the ecosystem.
FBTC maintains a 1:1 backing with Bitcoin, meaning each FBTC token represents one Bitcoin held in reserve. The token operates on a minting and burning mechanism where users can deposit Bitcoin to mint FBTC or burn FBTC to redeem Bitcoin.
Consensus Mechanism and Network Security Model
Institutional Grade Security: Secured by a robust security council comprising Antalpha, Galaxy, and Mantle, offering the robust infrastructure and full transparency institutions demand. The security council, which now includes Galaxy Digital as a core member alongside other institutional partners, provides robust oversight of risk frameworks and protocol security.
Unlike opaque wrapped assets, FBTC is designed for full verifiability in trust-minimized environments. This means institutional participants can independently verify Bitcoin backing and monitor protocol operations without relying on centralized intermediaries. By ensuring Bitcoin liquidity is transparent, auditable, and fully backed, FBTC sets the standard for institutional-grade, decentralized finance that preserves both security and capital efficiency.
Key Partnerships and Ecosystem Integrations
Function is supported by Galaxy Digital, Mantle, Antalpha Prime, and leading institutions. Crypto infrastructure firm Function has closed a $10 million seed round led by Galaxy Digital (GLXY), with participation from Antalpha (ANTA) and Mantle.
FBTC is already integrated with over 8 major protocols and over 25 leading decentralized applications (dApps), including Aave, and Babylon. Various protocols and platforms support $ƒBTC, including Avalon, Lombard, Bedrock, Lorenzo, PumpBTC, StakeStone, Ethena, Lendle, Uniswap, OpenBit, Merchant Moe.
FBTC will be integrated with wallets such as Binance Wallet, Bybit Wallet, Bitget Wallet, OKX Wallet, Particle Network, TokenPocket and UniSat.
Competitive Advantages and Unique Value Proposition
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.
FBTC is omnichain, institutional-grade, and built to scale. It's the first Bitcoin primitive that behaves like a yield-bearing composable asset, not just a bridge token. The difference is in the design: composability, security, and liquidity are native to FBTC, not bolted on.
FBTC uses cross-chain interoperability, which allows it to operate on multiple blockchains, facilitating diverse use cases. Although FBTC employs an omni-chain approach with MPC for secure custody and cross-chain functionality, WBTC, on the other hand, operates primarily within the Ethereum ecosystem as an ERC20 token.
Current Development Activity and Roadmap Highlights
Function's flagship product, FBTC, a fully reserved and composable bitcoin representation, has already amassed $1.5 billion in total value locked (TVL).
The $10 million seed funding will allow Function to expand its product suite, accelerate its integration with more DeFi protocols, and continue building the foundational infrastructure necessary to make Bitcoin a truly functional, liquid, and productive financial asset in the evolving digital economy.
FBTC unveils market-first yield enhancement strategies within the Bitcoin ecosystem to amplify its velocity and composability: Babylon Staking: Vaults that earn yield from Babylon native staking · Basis Trading: Vaults for high frequency trading funding strategies across CEXs and DeFi platforms.
By 2026, treating bitcoin as a passive treasury asset may no longer be enough. The new standard will be actively earning yield. We're evolving from wrapped assets to functional infrastructure that's programmable and institutional-grade to transform bitcoin into a productive asset class.
