Ripple Maps Out Post-Quantum XRPL Transition Through 2028 as Whales Add 360M XRP

Ripple has published a multi-stage plan to prepare the XRP Ledger (XRPL) for a post-quantum era, targeting full production readiness by 2028. The company frames the challenge as both cryptographic and operational, aiming to protect current users while maintaining network reliability and settlement performance as quantum computing research accelerates across the digital-asset industry. Ripple's roadmap starts with contingency planning for a potential "QDay" scenario—a point at which today's public-key cryptography could no longer be considered secure. In such a case, XRPL would need a safe migration route to move funds from classical-cryptography accounts to post-quantum-secure accounts. One option under consideration involves zero-knowledge proofs that could let users prove ownership of existing keys without revealing sensitive information. The company expects to devote the first half of 2026 to network-wide testing of post-quantum cryptography, focusing on how larger keys and signatures affect storage, bandwidth, and transaction performance. Ripple said it is evaluating NIST-recommended algorithms under XRPL's real transaction conditions. In the second half of 2026, Ripple plans to run hybrid signature models on Devnet, pairing post-quantum schemes with existing elliptic-curve signatures so developers can benchmark performance and usability without impacting the live network. The final stage would proceed through XRPL's formal amendment process and culminate in a network-wide transition, with a deadline target of no later than 2028. Ripple noted that XRPL has design features that could ease an eventual migration. Native key rotation allows users to transition away from older keys over time without changing the underlying account structure, offering a cleaner path than networks that require assets to be moved into new wallets. Ripple also cited seed-based deterministic key generation as a tool that could support more controlled upgrades. The company emphasized these are not post-quantum solutions by themselves, but useful building blocks. Ripple is also working with Project Eleven on early-stage development, including validator testing, Devnet benchmarking, and custody wallet prototypes using hybrid post-quantum signing approaches. The roadmap coincides with renewed debate over XRP's technical outlook. Analyst Ali Charts said XRP appears to be shifting from a bearish structure toward a bullish one, pointing to a daily SuperTrend buy signal for the first time since January as evidence that selling pressure may be easing after a prolonged consolidation. Ali Charts also reported that whale wallets accumulated roughly 360 million XRP over the past week, citing Santiment on-chain data. On shorter time frames, he said XRP has formed a symmetrical triangle, a setup that can precede a sharp move; the pattern implies a potential 35% swing once price breaks from the range. According to the analysis, a daily close above $1.55 would strengthen the bullish case and could clear a path toward $1.90. A drop below the $1.30 support area would challenge that bullish structure.
