Huo Xing Finance reports that on April 21, Ripple released a post-quantum multi-phase roadmap for the XRPL, aiming to equip the XRP Ledger (XRPL) with resilience against future quantum threats and targeting full readiness by 2028. The roadmap consists of four phases: Phase one, post-quantum recovery (Q-Day preparation), focuses on developing contingency plans to ensure secure migration of funds in the event classical cryptographic standards are broken; Phase two, scheduled for the first half of 2026, involves proactive planning and experimentation to assess quantum risks and test NIST-recommended algorithms in collaboration with Project Eleven; Phase three, expected in the second half of 2026, will integrate post-quantum signature schemes into Devnet and explore privacy primitives; Phase four, targeting 2028, aims to propose new amendments to the ecosystem to achieve a full native transition to post-quantum cryptography. Ripple notes that XRPL’s existing key rotation and seed-based key generation capabilities provide a foundational advantage, giving it native protocol superiority over networks like Ethereum in addressing quantum threats.

Summary
On April 21, Ripple released a post-quantum roadmap for the XRP Ledger, outlining a four-phase plan to secure the network against quantum threats by 2028. The strategy includes post-quantum recovery in Phase 1, testing with Project Eleven in Phase 2 (Q1 2026), Devnet integration in Phase 3 (Q2 2026), and native encryption amendments in Phase 4 (2028). The on-chain update highlights XRPL’s built-in key rotation and seed-based generation as a protocol-level advantage over other networks. The upgrade aims to ensure long-term security and adaptability.
