The XRP Ledger Foundation says the XRP Ledger is structurally prepared for the Quantum Era. It cited built-in key rotation and an account-based design as core features that could support a future move toward quantum-resistant signatures for users and businesses.
In a post on X, the foundation said users may keep the same XRP wallet addresses during that shift. These addresses, known as r-addresses, are already familiar to customers, exchanges, custodians, and payment firms.

Ripple, Project Eleven Target Post-Quantum Security
The update came after a new partnership between Ripple and Project Eleven. The collaboration is to enhance the post-quantum readiness of the XRP Ledger ecosystem via audits, testing, and engineering.
Project Eleven said that the initiative is to bring blockchain quantum security out of theory. It stated that the work was a practical move towards real deployment for post-quantum protection.
The firm cautioned that advanced quantum computers could soon pose a risk to cryptography relied on by major blockchains. It included Bitcoin, Ethereum, XRP, and Solana in the list of networks that may require additional measures in the future.
Global timelines have placed pressure on the discussion. Project Eleven stated the U.S. government has pledged to move away from the weak encryption standards by 2035.
A number of large tech companies have also begun their transitions. The company says that Google and Cloudflare aim to make the transition to quantum-safe systems by 2029.
The majority of blockchain discussion about quantum risk is still academic, said Project Eleven CEO Alex Pruden. The issue is just a problem that Ripple is approaching as an engineering one, which requires working systems, he said.
XRP Ledger Builds Path to Quantum-Safe Systems
RippleX Head of Engineering J. Ayo Akinyele said the XRP Ledger is not starting from zero. He pointed to key rotation and coordinated validator upgrades as important foundations.
Validators, custody systems, wallets, and network infrastructure will be audited as per the plan. Project Eleven will evaluate these and provide an identification of potential quantum vulnerabilities throughout the ecosystem.
Hybrid signature development will also be a part of the collaboration. These systems would integrate existing cryptographic techniques with quantum-resistant ones for a more secure transition.
The prototype for a custody wallet that is secure for quantum computers is also included. The work will involve code, performance testing, and a roadmap for production deployment, Project Eleven said.
Project Eleven was established in 2024 and has been working on post-quantum cryptography. In January 2026, Castle Island Ventures led the company’s $20 million round.
It also maintains the Bitcoin Risq List, which lists potentially quantum-vulnerable Bitcoin holdings, and created Quantum Vault, a tool for post-quantum wallet security.
Project Eleven also created Quantum Vault as a model to secure wallets with post-quantum technology. According to the company, the Ripple partnership is the largest blockchain security deal.
