XRPL Amendment #420 Sets Single-Use Keys for Quantum Risk, Dec. 20, 2025

According to U.Today, developer Ed Hennis filed XRPL Amendment idea #420 to let XRP Ledger accounts rotate a single-use signing key on every transaction. On December 20, 2025, Vet noted the "Quantum Safe" draft, which assumes XRPL's validation speed could limit attackers even if a public key is briefly exposed. Proposed field names include "SingleUseKey" and "QuantumSafeKey", and the feature is positioned as an optional security upgrade.
