XRP Ledger Quantum-Proof Accounts: No Extra Fees Planned
Summary
The XRP Ledger Foundation’s quantum-resistance design would let account owners add an ML-DSA-44 signing key and disable their existing key without moving funds or paying a higher base fee. The account address and balance would remain unchanged, while larger signatures increase storage demands for network operators. Implementation is unfinished: developers are resolving differences across software implementations, with testing and a migration study planned for 2027 and further work expected through 2028. The approach depends on users and institutions actively retiring vulnerable keys; validator approval, audits and education are also still required.
