XRP Ledger and Ripple Work With Project Eleven on Quantum-Safe Upgrade

Project Eleven said it is collaborating with Ripple to assess XRP Ledger vulnerabilities and support a full migration to post-quantum security by 2028, extending Ripple’s previously disclosed April partnership update.

Fact Check
The claim is strongly supported by primary and official sources. Ripple's own blog post on ripple.com ('Post-Quantum Readiness on the XRP Ledger', April 20, 2026) confirms the Project Eleven partnership and the phased quantum-safe roadmap. The XRP Ledger Foundation's official X post (May 19, 2026) directly and explicitly states that XRPL's architecture enables 'seamless migration to quantum-resistant signatures while preserving existing r-addresses' - directly corroborating the specific claim that wallet addresses need not change. The KuCoin news summary (May 19, 2026) and the CoinDesk-linked X post (May 20, 2026) provide independent corroboration of the partnership scope. The cryptonews.net article further confirms the technical basis: XRPL's native key rotation mechanism is what makes address-preserving quantum migration possible. No conflicting evidence was found. All sources consistently confirm both the Ripple-Project Eleven collaboration and the address-preservation capability.
Summary

Project Eleven announced on the 19th that it is collaborating with Ripple to assess vulnerabilities in the XRP Ledger and advance post-quantum security for XRPL, with a full migration targeted by 2028. The update adds a specific migration timeline to the broader quantum-security effort previously described by Ripple, which includes evaluating validators, custody systems, wallets, and networking layers, as well as developing code, testing performance, and preparing production deployment. Ripple had already disclosed the partnership in April.

Terms & Concepts
  • XRP Ledger: A blockchain-based ledger used for XRP-related payments and applications, maintained by a network of validators.
  • Post-quantum security: Cryptographic protection designed to remain secure against attacks from future quantum computers.
  • Validator: A network participant that helps verify, maintain, and coordinate activity on a blockchain or distributed ledger.
