Is your wallet exposed?
Enter any Ethereum address. We will scan its transaction history and balance to calculate your quantum vulnerability. Know your risk before Q-Day arrives.
Q-Day is coming.
Q-Day is the moment quantum computers become powerful enough to break the cryptography securing most of today's digital assets. Once your public key is exposed, a sufficiently powerful quantum computer can derive your private key and drain your wallet without your knowledge.
The window to act is open. It will not stay that way.
Two risk factors. One score.
The Quantum Risk Checker scans any Ethereum address or ENS name and calculates a Quantum Readiness Score based on two signals:
Every outgoing transaction permanently exposes your public key on-chain. The longer it has been exposed, the higher the risk.
The higher the balance in an exposed wallet, the more attractive the target. High balance combined with an exposed key means maximum risk.
Got risk?
Here's what to do about it.
If your wallet is exposed, the only real solution is moving your assets to a quantum-secure address. The Quantus wallet is built on a chain where every transaction is signed with post-quantum cryptography, meaning your assets are protected not just today, but when quantum computers arrive.
