Scanner
Your Private Payment Radar.
Announcements are public; knowing which one is yours is not. This is the process that turns a stream of anonymous announcements into your payment list.

Scanning prerequisites
- Unlocked identity — matching needs your private viewing key.
- Announcer address — there is nothing to read without one.
No identity in this session
Create a stealth identity on the Receive or Stealth Identity page to check announcements against a real viewing key.
Where the viewing key lives
Matching an announcement requires your private viewing key. That computation happens in this browser — the key is handed to the scanner as a callback and never leaves the provider that owns it, so it never reaches a backend.
The trade-off is that scanning only runs while you are here with the vault unlocked. A continuously-running server-side scanner would need your viewing key, which is a decision we have not taken.
An announcement is not a payment
Announcing is permissionless — anyone can claim anything about any address. A view-tag hit and an address match only mean an announcement addresses you.
So the scanner reads the actual balance at each matched address and discards anything holding nothing. Only verified balances appear in your payment list.
