A SEPARATE LINE OF DEFENSE

Keep your wallet.
Rethink what it controls.

Your everyday wallet is for moving.
Bunker is for holding. Deposit into a program-controlled vault, then authorize withdrawals with a separate, one-time hash key.

Built around a smaller surface

Create, deposit, withdraw. No trading, arbitrary calls, or unnecessary permissions.

A different key to the door

Your connected wallet pays network fees. It does not hold your Bunker withdrawal key.

Every spend, a fresh authority

A successful withdrawal rotates authorization in the same atomic transaction.

UNDERSTAND IT IN ONE MINUTE

What if your
wallet was compromised?

Move a simulated portfolio into Bunker. Attempt a withdrawal without its separate key. See why authorization matters.

TRUST SHOULD BE INSPECTABLE

Security is a process.
Not a promise on a website.

Bunker is an experimental product built on documented Winternitz prior art. It is not audited or approved for real funds, and it does not make the Solana network post-quantum.
