About
Project Eleven is a US-based cybersecurity company founded in 2021 that develops post-quantum cryptographic infrastructure for blockchains and digital assets. Its work focuses on securing those systems against future quantum computing threats through quantum-resistant encryption technologies and post-quantum cryptographic protocols designed to hold up even once quantum computers can break traditional cryptographic methods. In January 2026, Project Eleven secured $20 million in Series A funding led by Castle Island Ventures to accelerate development of its quantum-resistant blockchain security solutions. The company provides quantum-safe security for cryptocurrency platforms, blockchain networks, digital asset management, and decentralized finance applications, and it develops cryptographic libraries, security protocols, and consulting services for blockchain and cryptocurrency companies preparing for the quantum computing era.
