Secure BTC wrapping and unwrapping with multi-signature MPC, enabling Bitcoin as a productive asset across DeFi and TradFi markets
About fxn.xyz
Function is focused on transforming Bitcoin from a passive store of value into a productive asset that powers global financial markets. The company operates in the decentralized finance (DeFi) and traditional finance (TradFi) sectors, providing a secure multi-signature, multi-party computation (MPC) process for wrapping and unwrapping Bitcoin. This enables Qualified Users to initiate mint and burn requests for FBTC, with BTC deposits or withdrawals validated before transactions are signed. Upon final confirmation, FBTC is minted on the destination chain or BTC is withdrawn onto the Bitcoin network. Function's business model revolves around creating a hyper-liquid and composable Bitcoin asset that integrates seamlessly into on-chain lending, structured yield products, and institutional-grade financial systems. By deploying into top protocols across Ethereum, Mantle, Arbitrum, and more, Function aims to unlock Bitcoin's potential as a yield-generating and capital-efficient reserve asset. The company serves both institutional clients and individual users looking to leverage Bitcoin's capabilities in the DeFi and TradFi markets. Keywords: Bitcoin, DeFi, TradFi, multi-signature, MPC, FBTC, yield, capital-efficient, institutional, hyper-liquid
