The XRP Ledger Foundation says the XRP Ledger is already structurally set for the “Quantum Era.”
It highlighted built-in key rotation and its native account-based architecture as major advantages in the transition toward quantum-resistant cryptography.
In a post on X, the foundation explained that XRPL users and businesses would be able to migrate to quantum-resistant signatures while keeping the same XRP wallet addresses, known as “r-addresses,” that customers already recognize and trust.
The organization also revealed that a full audit of the XRP Ledger’s network, wallet, and validator infrastructure by Project Eleven is underway ahead of a more comprehensive quantum-security deployment.
The comments followed a new announcement from Project Eleven confirming a collaboration with Ripple to strengthen post-quantum readiness across the XRP Ledger ecosystem.
Key Points
- Ripple and Project Eleven are working to prepare the XRP Ledger for future quantum security threats.
- XRPL can upgrade to quantum-safe signatures without changing existing XRP wallet addresses.
- Project Eleven is auditing XRPL wallets, validators, and custody systems for quantum risks.
- Ripple says XRPL already supports key rotation and validator upgrades for smoother migration.
Ripple and Project Eleven Push XRPL Quantum Readiness
Project Eleven described the partnership as one of the industry’s first major efforts to move post-quantum blockchain security from theory to real-world implementation.
According to the company, the cryptography securing major blockchains such as Bitcoin, Ethereum, XRP, and Solana could eventually become vulnerable to sufficiently advanced quantum computers.
The firm pointed to growing urgency around the issue. For instance, the U.S. government has established a 2035 deadline for federal systems to migrate away from vulnerable encryption standards.
Moreover, major technology companies, including Google and Cloudflare, have also targeted 2029 for their own transitions toward quantum-safe systems.
Alex Pruden, CEO of Project Eleven, said most blockchain discussions around quantum risk have remained at the research stage. On the other hand, Ripple is approaching the challenge as a practical engineering problem.
XRP Ledger Already Has Key Infrastructure in Place
RippleX Head of Engineering J. Ayo Akinyele said the XRPL ecosystem is not starting from zero because the network already supports capabilities such as key rotation and coordinated validator upgrades.
According to Akinyele, the goal is to ensure XRPL becomes production-ready long before quantum threats become critical.
As part of the collaboration, Project Eleven will conduct a full audit covering XRPL validators, custody systems, wallets, and networking layers to identify possible quantum vulnerabilities.
The initiative will also include development of hybrid signature systems that combine existing cryptographic standards with quantum-resistant protections, alongside a prototype quantum-secure custody wallet.
Project Eleven said the collaboration will deliver working code, real-world performance testing, and a roadmap toward production deployment.
Project Eleven Expands Quantum Security Push
Founded in 2024, Project Eleven has emerged as a major player in post-quantum cryptography. The company raised $20 million in January 2026 in a funding round led by Castle Island Ventures.
It also operates the Bitcoin Risq List, which tracks potentially quantum-vulnerable Bitcoin holdings, and Quantum Vault, a reference implementation for post-quantum wallet security.
According to the company, the Ripple collaboration represents its most comprehensive blockchain security engagement so far.
