Q-Day readiness
Q-Day is sooner than you think
Check your Ethereum wallet's quantum vulnerability risk.
Total ECDSA wallet value-at-risk on ETH
$1,200,000,000,000
Approx. value secured solely by ECDSA (secp256k1 ethereum elliptic curve) signatures on Ethereum mainnet. A sufficiently powerful quantum computer running Shor's algorithm could derive private keys from public keys, draining every wallet that has ever broadcast a transaction.
Why this matters
ECDSA is not quantum-safe
Every Ethereum EOA is secured by an ECDSA keypair on the secp256k1 curve. Shor's algorithm, on a sufficiently large fault-tolerant quantum computer, derives the private key from the exposed public key in polynomial time.
Your public key leaks on first send
Addresses are hashes, but the public key is revealed the first time you sign a transaction. Once revealed, every dormant wallet with a visible pubkey becomes a sitting target on Q-Day.
Migration is the only defense
Until you migrate to a wallet signing with post-quantum schemes (SPHINCS+, Falcon, ML-DSA), your assets remain at risk. PQ1™ signs every transaction with SPHINCS+, so there is no ECDSA fallback to break.
Migrate before Q-Day.
