Project Eleven has acquired Riva Labs, adding cryptography and blockchain engineering expertise as the company expands its infrastructure for protecting digital assets against future quantum-computing threats.
Financial terms of the transaction were not disclosed.
The acquisition brings Riva Labs’ team, technology and intellectual property into Project Eleven, expanding its capabilities across post-quantum signatures, wallets, multiparty computation, account abstraction and blockchain infrastructure.
Riva has focused on translating post-quantum cryptographic research into systems that can operate across Ethereum and other public blockchains. Its work includes hash-based post-quantum signatures, post-quantum MPC, wallet infrastructure, account abstraction and hardware signing.
The company has also demonstrated post-quantum signing on consumer hardware, reflecting its emphasis on moving cryptographic research toward deployable applications.
Project Eleven plans to integrate Riva’s team and technology into its broader research and product operations spanning post-quantum cryptography, digital asset custody and blockchain security.
“Riva Labs is exactly the kind of talent we want at Project Eleven: deeply technical and focused on turning cryptographic research into systems that can actually be deployed,” said Alex Pruden, CEO and co-founder of Project Eleven.
Pruden said the acquisition strengthens Project Eleven’s research and engineering organization while adding technology that can support its work on post-quantum security for digital assets.
Project Eleven is developing infrastructure intended to help digital asset networks and applications migrate to cryptographic systems capable of resisting potential attacks from quantum computers.
The company is approaching that transition across multiple layers of blockchain infrastructure rather than treating signatures, wallets, key management and protocols as separate challenges. Adding Riva’s expertise gives Project Eleven additional engineering resources across several of those areas.
Riva has also incorporated artificial intelligence into its cryptographic research and engineering processes. Project Eleven said that capability will become part of its broader work in post-quantum cryptography and crypto agility.
The companies view AI as a tool that can accelerate cryptographic research and cryptanalysis by allowing new approaches to be developed, tested and challenged more rapidly.
“Project Eleven and Riva Labs came at this problem from different directions and reached many of the same conclusions about what the industry needs,” said Matteo Vena, co-founder of Riva Labs.
“Upgrading the public networks the future will run on, without compromising the properties that make them valuable in the first place, is a monumental challenge,” Vena added. “Our focus is on giving the industry the tools to accelerate that transition, and joining Project Eleven lets us do it at a much larger scale.”
Riva Labs operates as a cryptography and protocol engineering team focused on post-quantum infrastructure for digital assets, with particular expertise in hash-based signatures. Its work has covered software wallets, hardware signing and MPC infrastructure on Ethereum and other public blockchains, along with contributions to protocols and open-source software.
Project Eleven develops infrastructure and tools for post-quantum security, combining expertise in cryptography, blockchain technology and financial systems.
With Riva’s team and intellectual property joining the company, Project Eleven is expanding the research and engineering resources it can apply to the technical challenges involved in migrating digital asset infrastructure toward post-quantum cryptographic standards.
