XRP Ledger plots quantum-resistant accounts by 2028

The XRP Ledger Foundation has published a design for quantum-resistant accounts that would let owners add a quantum-safe key and switch off the old, vulnerable signing key instead of migrating balances wholesale — aimed at protecting accounts from a future quantum computer capable of deriving private keys from exposed public keys. The plan is part of a roadmap the foundation says puts the network on track for a full transition by 2028, with no extra fees for users. No implementation or activation timeline was disclosed beyond the 2028 transition target.
