Experts say XRP’s design exposes a smaller portion of its supply to a potential quantum attack than Bitcoin.
Armor against quantum attacks?
With the recent rise of crypto quantum panic or “quantum FUD” (fear, uncertainty and doubt) following Google’s “doomsday” white paper, many cryptocurrency developers, as analysts, have taken it upon themselves to conduct tests to ensure their coins are secure. Others are already there writing post-quantum security protocols and proofs.
Veterinarian, XRP Ledger dUNL validator and long-time XRPL collaborator shared in a post on the X social network his belief that the architecture underlying XRP is better prepared for a potential quantum threat than Bitcoin’s.
Fast quantum vulnerability checking for XRP acc.
Approximately 300,000 XRP accounts holding 2.4 billion XRP have never transacted, so the public key is unknown and quantum secure.
while only 2 accounts with larger holdings of 21 million XRP are inactive (inactive for 5 years) and their public key is exposed.
Asleep…

In compact: this is because of the way keys and accounts are handled in XRPL.
XRP Quantum Armor Explained
The primary risk that quantum computers pose, and which greatly worries many people involved in cryptocurrencies, is that in theory a future quantum computer could obtain a private key that will be exposed when the wallet sends a transaction, thus allowing all funds in the wallet to be exhausted.
However, a “quick quantum XRP Ac vulnerability check” conducted by Vet revealed that approximately 300,000 XRP accounts containing approximately 2.4 billion XRP have never sent funds, so their public keys are undisclosed and “quantum secure” by default.
According to the XRPL verifier, there are only two long-dormant XRP whale accounts, holding a total of approximately 21 million XRP, whose public key is currently exposed. The balance of these accounts represents only about 0.03% of the circulating supply, which is a rounding error relative to the total supply on the network (circulating supply is approximately 61 billion XRP at the beginning of April 2026, according to Coinglass data).

XRPL’s account-based model allows key rotation signing without transferring funds, and escrow/timelock tools can lock tokens under certain conditions, giving holders more opportunities to strengthen security ahead of any quantum breakthrough.
On the other hand, in the case of Bitcoin, early P2PK results and exposed public keys leave an estimated 11-37% of BTC potentially vulnerable to attacks in a future quantum scenario. This includes Satoshi-era coins that cannot simply turn keys.
Therefore, despite Ripple and Bitcoin’s very similar approaches to quantum resistance, their positions on dormant whale wallets diverge, simply because almost none exist on XRP.
What does this mean for XRP investors
Wet closes the post with reassuring words for XRP holders:
Important – Your XRP is secure, there are no known quantum computers that could threaten public blockchains. During this time, the industry found a way out.
The immediate conclusion for XRP holders is that on-chain data and the XRPL toolkit indicate a relatively restricted attack surface, especially for busy users who can change keys in advance.
The quantum debate is transforming into a up-to-date risk pricing vector between Bitcoin and large-cap altcoins. If this narrative continues, any advancements in fully quantum-resistant XRPL testnets or mainnet modernization could become a up-to-date catalyst for the next security-driven rotation.
