Is your wallet
quantum-exposed?
Paste any Bitcoin, Ethereum or Solana address. We read the live chain and tell you whether its public key is already on-chain, the one thing Shor's algorithm needs to recover a private key.
01Your public key leaks
Solana addresses are Ed25519 public keys. Bitcoin and Ethereum reveal the public key the first time a wallet signs a spend. Taproot shows it from day one.
02Q-day reverses it
A large fault-tolerant quantum computer running Shor's algorithm derives the private key from the public key. Every exposed wallet becomes spendable by someone else.
03Lattices don't leak
QuantumProof signs with ML-DSA (NIST FIPS 204). There's no known quantum attack on it, and no elliptic-curve key ever touches the chain.
