This month, the XRP Ledger validator known as Vet published a forensic analysis of the protocol’s quantum exposures after scanning the entire history of 7,810,364 accounts.
Results reproducible through public repositories show that 76.82 billion XRP is in quantum exposure accounts; 96% of that volume belongs to active accounts that can be migrated..
Vet operates under a pseudonym, but its identity as a participant in the ecosystem is verifiable. It maintains an active validator registered with XRPScan on the xrp.vet domain and its technical analysis is regularly cited in professional media.
According to researchers, An account is only quantum vulnerable if it has ever signed a transaction.which exposes the public key to the transaction history. Accounts that have never issued signed transactions do not have a visible public key and therefore do not represent an exploitable attack vector.
The analysis establishes an operational distinction between current risk and structural risk. The veterinarian is 0.03% of the total currency is in dormant accounts with the keys exposed and unrecoverable. — The owner has died, lost the key, or has been permanently inaccessible. In contrast to Bitcoin, where Google Quantum AI estimates that quantum computers can derive private keys in less than 9 minutes and approximately 6.9 million BTC have public keys visible on-chain, XRPL has a centralized key rotation mechanism that allows signing authority to be updated without moving funds or changing addresses.
The dilemma of dormant funds
The most sensitive findings of the analysis are not technical, but governance. veterinarian suggests that the community needs to define how the funds are spent For accounts whose owners cannot complete the migration: allow a quantum attacker to take over or intervene collectively. The researchers describe this as a “litmus test” (or litmus test) for the social layer of networks in the face of quantum threats, and warn that there are no technical answers that automatically resolve this dilemma.
In parallel with the discussion generated by the analysis, Ripple on April 20 announced a four-step roadmap for adapting the XRP ledger to a post-quantum scenario. Aiming to complete the transition by 2028. The emergency phase includes the forced migration of accounts to a quantum-resistant scheme with zero-knowledge proofs in case “Q-Day” arrives sooner than expected. Engineer Denis Angell introduced ML-DSA (CRYSTALS-Dilithium) signatures, already a NIST-approved standard, to the AlphaNet testnet in December 2025, although the mainnet has not migrated yet.
Vet concludes that a multi-signature setup with active key rotation is required for accounts to operate truly securely in a post-quantum environment. He points out that a single key rotation only protects the funds until the moment they need to be used, at which point the keys are made public again.
