Create a bunker

Build your bunker.

Three steps: make a hash commitment, pick what goes in, seal it. The key is made in your browser and never sent anywhere. Preview: the bunker program isn't deployed yet, so sealing opens with devnet.

Name it

Only you see this. It helps you tell bunkers apart.

Make the commitment

67 hash chains, 15 steps each, folded into one 32-byte commitment. This is the only thing the bunker will ever store.

No commitment yet.

Choose a deposit

How much SOL goes behind the door.

SOL

Seal

Connect Phantom to fund the bunker. The deposit is a normal SOL transfer. Every withdrawal after that needs a hash signature.

The bunker program is not deployed yet. Sealing turns on with the devnet launch. Follow @Bunker_Protocol for it.

Before you seal

Your secret is the only way back in. Lose it and the bunker stays closed for good. There's no reset, no support desk and no override. That's the point.
