The XRP Ledger is taking concrete steps to become “quantum-ready.” Project Eleven, a quantum security firm, has launched a full audit of XRPL’s validators, custody systems, wallets and networking layers in partnership with Ripple — an effort aimed at moving post-quantum blockchain security from theory into production.
What the review will do
- Audit core components: validators, custody, wallets and networking.
- Produce working code, real-world performance tests and a migration roadmap.
- Prototype a quantum-secure custody wallet and build hybrid signature systems that combine today’s cryptography with quantum-resistant algorithms.
Project Eleven framed the collaboration as one of the first major industry moves to operationalize post-quantum defenses. CEO Alex Pruden emphasized that, unlike much of the industry’s research-focused conversation, Ripple is approaching quantum risk as an engineering problem with actionable deliverables.
Why now
Governments and major cloud providers are already setting deadlines: the U.S. government wants federal systems moved to quantum-resistant standards by 2035, while Google and Cloudflare have targeted transitions around 2029. Those timelines underscore the urgency: advanced quantum computers could one day break the public-key cryptography that secures Bitcoin, Ethereum, XRP, Solana and other networks.
XRPL’s current advantages
The XRP Ledger Foundation says XRPL isn’t starting from scratch. XRPL’s native account-based architecture already supports key rotation and coordinated validator upgrades — features that should make implementing quantum-resistant signatures smoother. Importantly, the foundation notes users and businesses will be able to adopt quantum-resistant signatures without changing their existing XRP wallet addresses (r-addresses), removing a major operational headache during migration.
RippleX engineering lead J. Ayo Akinyele said the objective is to have XRPL production-ready well before quantum threats materialize.
Why it matters
If successful, the Project Eleven–Ripple program would deliver tested tools and migration paths that other blockchain teams could study or emulate. Building hybrid signature schemes and prototype custody solutions now gives the ecosystem practical options to protect assets against a future quantum threat rather than waiting until that threat is imminent.
Project Eleven described the Ripple engagement as its most comprehensive blockchain security project to date, signaling a potential shift in how blockchains prepare for the long-term risks posed by quantum computing.
