In each vendor's browser
Vendors bid — encrypted
Each vendor's bid is locked in their own browser before it's ever sent. We only receive an unreadable blob.
Until your deadline
Sealed until your deadline
No one can open a single bid early — not another vendor, not a hacker, not us. Deadlines run on our clock.

You can't be locked out.
We can't peek.
Your bids are protected by three keys — any two open them: your passphrase, a recovery key you keep, and a sealed share we hold. Lose one and you're still fine. And we can never open a bid on our own.
- Encrypted end-to-endBids are sealed in the vendor's browser — we store ciphertext we literally cannot read.
- Never locked outForget your passphrase? Your recovery key + our escrow share still open the bids.
- Tamper-evidentEvery event is written to an append-only, hash-chained audit trail. Nothing can be quietly changed.
