What BlockSpaces does
BlockSpaces is a Tampa, Florida-based fintech infrastructure company founded in 2018 that builds Bitcoin-native collateral and risk management software for institutional financial services. The company operates ARCC (Auto Reconciled Collateral Contracts), a platform that automates contract enforcement, margin calls, collateral movement, and settlement for Bitcoin-backed financial products. Its target customers are U.S. banks and credit unions, corporate treasurers, OTC desks and capital markets participants, Bitcoin miners, corporate treasury holders of Bitcoin, and hedge funds seeking institutional-grade infrastructure to deploy Bitcoin as programmable collateral without selling the underlying asset.
ARCC is built on Smart Channels, BlockSpaces' proprietary programmable framework that extends Bitcoin's Layer 2 capabilities using Hash Time-Locked Contracts (HTLCs), Lightning Network primitives, and Taproot Assets. The architecture enables private, bilateral, trust-minimized execution environments for financial contracts without wrapping tokens, sidechains, or custodial bridges, and supports both Bitcoin collateral and Taproot Asset-based stablecoins. BlockSpaces also offers a Blockspace Forwards Market for institutions to hedge and lock in Bitcoin transaction fees. The company reports operational experience running infrastructure across more than 40 blockchain protocols with tens of thousands of production nodes. ARCC integrates via API alongside existing origination, custody, and risk systems without requiring replacement of core infrastructure.
BlockSpaces distributes its platform exclusively through a direct enterprise sales motion with a consultative "Book a Meeting" process and revenue is generated via platform licensing on a subscription basis under multi-year contracts; pricing is not publicly disclosed. The company has raised approximately $10 million across multiple rounds since 2018, including a $5.75M seed round in January 2022 led by Leadout Capital and a $2M strategic round in May 2025 led by Axiom. BlockSpaces is led by co-founders Rosa Shores (CEO) and Gabe Higgins (CTO), with board representation from Leadout Capital, Hyperion Decimus, and Axiom, and advisory support from Matthew Bowen on banking partnerships.
