Ripple News: XRP Validator Says 300K XRPL Accounts With 2.4B XRP Remain Safe

Key Insights:

• XRPL quantum check found about 300,000 accounts holding 2.4 billion XRP remain safe because their public keys have not been exposed.
• The review covered about 7.8 million XRPL accounts and identified only two dormant accounts with exposed public keys holding 21 million XRP.
• XRPL Labs tested ML-DSA on AlphaNet, adding quantum accounts, transactions, and consensus as post-quantum research advances.

Ripple News focused on the XRP Ledger after validator Vet shared the results of a quantum-vulnerability check of XRPL accounts. The review found that about 300,000 accounts holding roughly 2.4 billion XRP remain protected because their public keys have never been exposed through outgoing transactions. Vet said these accounts are harder to target under the current quantum attack models. The data also showed that only a very small share of XRP supply sits in older inactive accounts with visible public keys. The update comes as XRPL developers continue testing post-quantum tools on AlphaNet.

Ripple News: Quantum Check Shows Limited Exposed Supply

Vet reported that around 300,000 XRPL accounts are currently considered quantum safe because their public keys remain hidden. These accounts have not made transactions, which means the information needed for a future quantum-based attack is not publicly available. Notably, together these accounts hold about 2.4 billion XRP.

The Ripple news also said that only two inactive accounts holding a combined 21 million XRP have exposed public keys and have remained dormant for more than five years. Based on that review, the amount of XRP facing notable quantum exposure remains limited. Vet placed the vulnerable share at about 0.03% of the total XRP supply.

Dormant Wallets Remain a Small Part of XRPL

At the time of reporting, the XRP Ledger had more than 7.76 million activated addresses and about 1.13 million dormant wallets. Many of those inactive wallets hold only the minimum reserve, estimated at 10-20 XRP. That reduces the amount of XRP tied to long-term inactive accounts across the network.

Data shared in the review also showed that accounts inactive for more than two years make up about 3.8% to 4.1% of the network. Vet said this portion belongs to a small permanent-loss category and has remained relatively stable over time. Vulnerable inactive whale accounts are rare on XRPL, which sets the network apart from chains where older large wallets often remain untouched for long periods.

XRPL Differs from Bitcoin on Public Key Exposure

Vet compared XRPL’s account structure with Bitcoin, where some older wallets were created under formats that exposed public keys more directly. In Bitcoin’s case, older pay-to-public-key wallets have drawn attention because they may become easier targets if quantum computing reaches a higher level. That includes long-dormant addresses often linked to early holders.

On XRPL, the validator said the structure is different because fewer large inactive wallets sit with exposed public keys for long periods. Most active XRP holders can also rotate keys when needed without changing wallet addresses. That built-in flexibility gives XRPL an extra tool as the industry continues to prepare for future cryptographic changes.

AlphaNet Tests Post-quantum Tools

The XRP Ledger mainnet still relies on traditional cryptographic systems such as ECDSA and Ed25519. These systems are widely used today, but researchers have long said that powerful enough quantum computers could break them through methods such as Shor’s algorithm. For now, no public quantum computer can do that at a blockchain scale.

XRPL developers have already tested post-quantum protections on AlphaNet. In December 2025, XRPL Labs engineer Denis Angell said AlphaNet became fully quantum secure using CRYSTALS-Dilithium, now known as ML-DSA. The testnet added Quantum Accounts, Quantum Transactions, and Quantum Consensus and supported quantum-signed transactions and smart contracts.

Research across the XRPL ecosystem continues to focus on key rotation, hybrid signing models, and a gradual migration path. Developers linked to Ripple and other contributors have also been exploring ways to combine current cryptographic methods with post-quantum systems during the transition period.
