Project Eleven Acquires Riva Labs to Expand Post-Quantum Research and Engineering

Riva Labs joins Project Eleven as the company brings more specialized post-quantum talent and technology under one roof.

NEW YORK, Sept. 29, 2026 /PRNewswire/ -- Project Eleven, the company building post-quantum security infrastructure for digital assets, today announced its acquisition of Riva Labs, expanding its expertise in post-quantum signatures, wallets, MPC, and account abstraction. The acquisition also brings technology and intellectual property developed through Riva's work across Ethereum and other public blockchains, adding to Project Eleven's capabilities in post-quantum cryptography and blockchain infrastructure.

Riva Labs has built a reputation for translating post-quantum cryptographic research into practical blockchain systems. Its work spans hash-based post-quantum signatures, post-quantum MPC, account abstraction, wallet infrastructure, and hardware signing, including recent demonstrations of post-quantum signing on consumer hardware.

The addition of Riva expands Project Eleven's research and engineering bench as the digital asset industry prepares for the complexity of post-quantum migration. Rather than treating signatures, wallets, key management and protocol infrastructure as separate problems, Project Eleven is bringing together expertise across each layer required to make that transition practical.
