# For Authorized Pingers

An authorized pinger can update the Vault’s heartbeat on behalf of the owner. Here’s how:

* **Verify Authorization**:
  * The owner must have called `setAuthorizedPinger` with your address and a valid ECDSA signature.
  * Check the `authorizedPinger` address via the Vault’s “Read Contract” section.
* **Update Heartbeat**:
  * Call `pingByPinger` to update the `lastHeartbeat` timestamp.
  * Requirements: Vault unclaimed, caller is the authorized pinger.

**How to Interact**:

1. Navigate to the Vault’s address on a block explorer.
2. In the “Write Contract” section, connect your wallet (must be the authorized pinger address).
3. Call `pingByPinger` and confirm the transaction.
