According to CoinDesk, XRP Ledger Foundation unveiled a quantum-resistant account design in its November 4 2027 protocol roadmap update. The design allows account owners to add quantum-resistant signing keys using the ML-DSA-44 signature scheme approved by the U.S. National Institute of Standards and Technology in 2024. Despite adding approximately 3.6 KB per transaction, users will incur no additional fees; network operators will absorb the storage costs. The foundation plans to initiate migration research in the first half of 2027, targeting full quantum transition by 2028.
