Bitcoin
- ExposedTaproot, and any address that has spent once.
- ShieldedAn address that has only ever received.
Paste any Bitcoin, Ethereum or Solana address. We read public chain data and tell you whether the key protecting it is already exposed.
Public chain data only. No keys, no wallet connection, no address stored.
A large enough quantum computer can derive a private key from the matching public key. Most chains publish that public key the moment an address spends. Nothing has to be intercepted, because the exposed keys are already public and stay that way.

The June 2026 executive order, EO 14413, puts federal deadlines on quantum readiness, and the machines it prepares for are the same ones that break today's encryption.
What EO 14413 requiresThis measures exposure rather than imminent theft. CoinShares argues the practically exploitable set is far smaller.
Full methodology and sourcesEstimated time until quantum computers can break the encryption securing today's digital assets.
Quip Network wraps wallets you already use with quantum-resistant protection across Bitcoin, EVM chains and Solana, using a firewall contract and a cosigner that requires both a classical and a quantum-resistant signature.
No. The cache and rate limiter key on an HMAC of the input, so nothing in the system can be read back as a list of addresses. Scoring runs in your browser, and the server reads public chain data the way a block explorer does.
No. Everything here comes from data that is already public, and reading it needs nothing from you beyond the address itself.
A Solana address is itself an ed25519 public key. Bitcoin and Ethereum put a hash in front of the key, which shields it until the address spends. Solana does not, so exposure there is a property of the account model. What you can still control is how much sits behind any one key.
It means only a hash of the key is on-chain today, which is the better position to be in. That stops being true the moment the address broadcasts a spend, because the signature publishes the key. Treat a shielded result as a reason to plan the move carefully rather than as a settled state.
