XRP Ledger Focuses on Plan for Quantum -Resistant Accounts at No Added Cost to Users

The XRP Ledger Foundation's 2027 roadmap describes letting account holders register an ML-DSA-44 signing key and disable the original classical key, keeping addresses and balances unchanged and the base fee unchanged. ML-DSA-44 (NIST FIPS 204, 2024) yields about 5,331 bytes of storage per protected transaction versus a 1,704-byte baseline, a burden falling on node operators rather than users. No quantum-resistant account type is live yet; the work is a draft specification with a migration study in H1 2027 and a target of completion by 2028.
