XRP Ledger plans a 2028 transition to quantum-resistant ML-DSA-44 keys, keeping base transaction fees unchanged while network operators absorb the 3,732-byte signature storage overhead.
The XRP Ledger Foundation's Nov. 4 roadmap adds quantum-resistant ML-DSA-44 signing keys with no change to base fees, targeting a full transition by 2028. That is a constructive, differentiating technical step for XRP, but it is only a design proposal: key-mismatch fixes, validator testing, a 2027 migration study and auditing are all still pending, so no near-term price driver.
The XRP Ledger Foundation has unveiled a roadmap to integrate ML-DSA-44 quantum-resistant signing keys into its protocol. The design, updated on Nov. 4, allows users to secure accounts against future quantum threats without increasing transaction fees, as network operators will absorb the additional storage requirements. A full transition is targeted for 2028, with a migration study scheduled for the first half of 2027.
Unlikely in the near term. It is a design proposal with the migration study planned for early 2027 and auditing afterward, so any benefit is gradual rather than an immediate catalyst.
The proposal keeps the base transaction fee unchanged; the extra storage for the larger keys and signatures is absorbed by the network operators who run validators.
