Project Eleven has raised $6 million in seed funding to accelerate the development of post-quantum cryptography infrastructure for Bitcoin and other digital assets. The round was co-led by Variant Fund and Quantonation, marking Quantonation’s first investment in the crypto sector. Other participants include Castle Island Ventures, Nebular, and Formation.
The company’s flagship initiative, “Yellowpages,” is a cryptographic registry designed to help Bitcoin holders proactively establish post-quantum ownership of their assets. The platform enables users to generate quantum-resistant keys and link them to their current Bitcoin addresses through verifiable proofs, all without requiring immediate blockchain transactions. This approach targets an estimated $600 billion in Bitcoin held in wallets with publicly exposed keys, which are at risk if cryptographically relevant quantum computers (CRQCs) emerge.
With this funding, Project Eleven plans to expand its team and advance development of quantum-secure infrastructure and standards. In addition to Bitcoin protections, the company is exploring broader applications of quantum mechanics for secure communication and transaction systems. The launch of Yellowpages marks a strategic step toward mitigating Q-Day risks—when quantum systems may break current cryptographic schemes—using free, open-source tools.
