Zafe, in 3D

One payment,
start to finish

Three phones share one vault. Scroll to play.

How it works

  1. Every phone holds a share of the key.

  2. Bob proposes a payment.

  3. You approve with one tap.

  4. Two shares make the key. It never exists on any phone.

  5. The vault opens. Sent, and on-chain it looks like any payment.

Every phone holds a share of the key.

One share can’t open anything.

Bob proposes a payment.

Everyone in the vault is notified.

Bob approves. His share goes in.

You approve with one tap.

Two shares make the key. It never exists on any phone.

The vault opens.

Sending…

Sent. On-chain, it looks like any payment.

Behind it

What you
didn’t see

Checked on every phone

Your phone checks each payment against the vault’s own keys. If anything’s off, it won’t sign.

  • Recipients
  • Amounts and memos
  • Change
  • Fee

Invisible on-chain

The phones sign together as one. To the chain it’s an ordinary shielded payment, like this real one from our testnet trial.
