What actually happened?
Ripple, the company behind the XRP Ledger (XRPL, a public blockchain network for payments and tokenization), is taking steps to make sure the network can hold up in the era of powerful quantum computers. CoinDesk reported on these preparations for so-called "Q-Day." Q-Day is the hypothetical moment when quantum computers become powerful enough to break the cryptography most blockchains rely on today.
According to CoinDesk, the threat is no longer purely theoretical. The outlet reports that a model from Anthropic last month cut the computational work needed to break one of the leading candidates for a post-quantum signature algorithm by a factor of 67 million. In the same week, according to CoinDesk, Bitcoin and Ethereum also published their own migration plans.
In parallel, Ripple is working to reduce the "attack surface" of the XRPL itself. According to CryptoSlate, the company recommended removing more than 10,000 lines of unused XChainBridge code, at a time when it is preparing to expand native lending features.
What is the "attack surface" and why is Ripple shrinking it?
Put simply, the attack surface is the sum of all the places in the code through which an attacker could break in. The less code there is, the fewer potential vulnerabilities.
According to CryptoSlate, Ripple:
- recommended removing more than 10,000 lines of unused XChainBridge code (related to the fact that, according to CryptoSlate, Axelar is leaving Ripple),
- is having the Lending Protocol V1.1 undergo a security audit run exclusively by artificial intelligence, specifically the Sherlock Audit Engine tool.
The timing is no accident. CryptoSlate reports that in the first half of 2026 alone, the market lost more than 1.31 billion dollars across 344 security incidents, with code vulnerabilities remaining the most common category of attack.
Does this mean the XRP Ledger is "quantum resistant"?
No. The fact that Ripple is working on preparations does not mean the network is protected against a quantum attack today. The sources describe preparations and recommendations, not a finished, deployed solution. The specific technical shape of the XRPL post-quantum migration, its schedule, and when (or whether) Q-Day will arrive do not follow from the available sources. These points remain open.
Moreover, an AI-only audit of the lending protocol is itself an experiment. How reliable it will be compared to a classic human audit remains to be seen.
Beware of confusion: the "Ledger" hardware wallet is a different story
Around the same time, a report surfaced that is easy to confuse with the XRP Ledger, even though it is unrelated. It concerns the Ledger hardware wallet.
According to the Polish site Incrypted, the OneKey Anzen team demonstrated an attack in which a user sees one transaction on the Ledger device but actually signs a different one. According to Incrypted, the problem involved the Ethereum app for Ledger in version 1.22.1, and OneKey CEO Yishi Wang reported reproducing the attack.
Decrypt, however, points to the other side of the coin: according to the manufacturer, this was not a "hack" of the Ledger, because the vulnerability was, according to the company, fixed before it could be exploited.
So these are two entirely separate things linked only by a similar name: "XRP Ledger" (the Ripple network) and "Ledger" (the maker of hardware wallets).
What to watch out for with this type of news
- Distinguish preparation from deployment. Announcing a plan is not the same as functional protection.
- Follow the specific numbers and dates. The speedup factor, the number of lines of code, the volume of losses in incidents, the app version. These are verifiable points.
- Do not mix up similar names. "XRP Ledger" and "Ledger" are two different things.
We will be able to verify this news later based on whether Ripple publishes a concrete technical plan for its post-quantum migration and whether the AI-led audit catches or misses real bugs.
