Cryptography company Project Eleven announced a collaboration with Ripple to combat quantum computing threats. The company stated that, as part of this partnership, they will work with Ripple to prepare the XRP Ledger (XRPL) for the post-quantum era.
Project Eleven stated that the cryptographic systems used in current blockchain infrastructures could be broken in the future by sufficiently powerful quantum computers. The company noted that major blockchain networks, including Bitcoin, Ethereum, Solana, and XRP, face similar security risks.
The collaboration involves a comprehensive quantum security audit of the XRP Ledger’s validator, custody, networking, and wallet layers. Additionally, plans include adding quantum-resistant hybrid signature systems on top of existing signature standards and developing a quantum-secure custodial wallet prototype. Project Eleven aims to deliver working code, performance data, and production-ready solutions at the end of the process.
Project Eleven CEO and co-founder Alex Pruden stated that much of the work on quantum risk in the blockchain sector remains in the research phase, and that Ripple is treating this issue as a “practical engineering problem.” Pruden said, “Every major blockchain is exposed to the same cryptographic vulnerability. However, Ripple’s approach focuses more on implementation than research.”
RippleX Engineering Director J. Ayo Akinyele argued that the quantum threat is no longer just theoretical. Akinyele stated that the XRP Ledger has existing infrastructure advantages such as key rotation and large-scale validator coordination, adding, “Our goal is not to react when Q-Day arrives, but to be ready for production before the need arises.”
The US government aims to phase out quantum-vulnerable encryption methods in federal systems by 2035, while technology companies like Google and Cloudflare plan to transition to post-quantum security standards in their own systems by 2029.
Founded in 2024, Project Eleven completed a $20 million funding round led by Castle Island Ventures in January 2026. The company is also developing the “Bitcoin Risk List,” which monitors Bitcoin assets at risk from quantum attacks, and the “Quantum Vault” project, which provides quantum-secure wallet infrastructure.
