Project Eleven Acquires Riva Labs for Post-Quantum Tech
The acquisition brings Riva's post-quantum signatures, wallet infrastructure and hardware-signing work under Project Eleven's research and product efforts.
Updated on Nov. 5, 2026 in Quantum Computing
Project Eleven acquired Riva Labs, a deal announced in a notice published on September 29, 2026. The transaction is a talent and intellectual-property move that brings technology developed across Ethereum (ETH) and other public blockchains into Project Eleven.
Why it matters
Project Eleven says the industry is preparing for the complexity of a post-quantum migration, and the notice states that AI is accelerating cryptographic research and cryptanalysis. The deal positions Riva's post-quantum and custody work within that effort.
Riva Labs has demonstrated post-quantum signing on consumer hardware and works on hash-based post-quantum signatures, post-quantum MPC, account abstraction, wallet infrastructure and hardware signing. The extraction does not specify performance metrics or deployment timelines for these capabilities.
The players
Project Eleven
Project Eleven is the acquiring company, focused on post-quantum cryptography and digital asset security.
Riva Labs
Riva Labs is the acquired company whose post-quantum signing and custody research developed across Ethereum and other public blockchains.
The details
Riva Labs' work includes hash-based post-quantum signatures, post-quantum multi-party computation, account abstraction, wallet infrastructure and hardware signing, and the company made AI a core part of its research and engineering. The Riva team and its technology become part of Project Eleven's broader research and product efforts across post-quantum cryptography, digital asset custody and blockchain security.

The Tech Race
The acquisition adds post-quantum signing and hardware-signing capabilities to Project Eleven as the blockchain industry prepares for a post-quantum migration. It sits alongside other custody moves in the same period, including Standard Chartered's agreement for Zodia Custody and Citi's addition of Bitcoin (BTC) to Custody+.
For people holding digital assets, the shift toward post-quantum signatures and hardware-based signing could eventually change how wallets and custody services protect keys. The acquisition is a company-level move, and the extraction does not indicate any immediate change to products available to users.
The takeaway
Post-quantum migration is becoming an operational priority for blockchain and custody firms, and acquisitions like this one signal that talent and cryptographic IP are being consolidated to meet it. Readers following digital-asset security should watch how these capabilities reach wallets and custody products.
