Q day needs
your public key.

A quantum computer cannot attack an address. It needs the public key behind it, and yours goes public the first time you sign. Bunker.imd checks any wallet, Safe or coin and shows what is already out.

Free public reads on six chains. No wallet needed. Nothing on this site can sign or send.

The machine is not switched on yet. Check anyway.

Bunker.imd is reading six chains.

Inside the bunker

Pick a room.

Coin scan

How much of a coin sits in wallets whose key is already public. Opens on $IMD.

Scan a coin → Live

My bunker

A watchlist for your addresses, with an alert the moment one of them signs.

Open my bunker → Live

Reports

A full quantum exposure report for a coin, a wallet or a Safe, with a link to share.

Create a report → Live

Key recovery

Paste a transaction and watch the signer's public key come out of the signature.

Recover a key → Preview

IMD hook up

Quantum, in plain words

Shor needs a key. Grover gets a hash.

Shor breaks curves

Shor's algorithm lets a large quantum computer work back from a public key to the private key. Every normal Ethereum and Bitcoin wallet rests on that one curve.

Grover only dents hashes

Against a hash the best known quantum attack is Grover's search, which halves the security level and no more. An address that still hides its key behind a hash stays far harder to reach.

So hide the key

Keep the bulk in an address that never signed. When it has to sign, move what is left to a fresh one. People call it bunker mode, and it needs no new wallet.
