XRP Ledger Foundation Plans 2027 Study for Quantum-Resistant Accounts

The XRP Ledger Foundation is preparing a quantum-resistant account-signing proposal aimed at exposed accounts, with a migration study planned for the first half of 2027 as developers resolve key-generation differences.

The proposal would let account holders register keys based on NIST-approved ML-DSA-44 and deactivate existing authentication keys. It targets accounts whose public keys have appeared on the ledger. The proposed option is designed to add this protection without increasing transaction fees, but the feature has not been implemented.

Developers are working to resolve differences in how Python, JavaScript and server implementations generate keys. Ripple has separately set a 2028 target for full post-quantum readiness.

The migration study is expected to examine how existing accounts could move to the new signing system and what account holders would need to do. It is planned for the first half of 2027.
