Is your wallet quantum-exposed?

Ethereum, Bitcoin and Solana sign with elliptic-curve keys (secp256k1 / Ed25519) that a future quantum computer can break. The ledger is permanent and public, so harvest now, decrypt later is trivial. On Ethereum/Bitcoin your key stays hidden until your first spend; on Solana the address IS the public key — exposed from day one. Paste an address to see if its key is exposed, how much is at risk, and whether it's migratable.

A cryptographically-relevant quantum computer is not imminent (current estimates: ~end of the decade). This is a planning tool — know your exposure, don't panic. Informational, not financial advice. Free, no signup. Open source: github.com/kaditang/quantum-exposure.
