How it works
The rules, in full.
Who gets asked, who sees what, who gets paid, and what a false alarm costs.
The life of an alert
Each arrow is a transaction tied to someone's wallet.
01
Raised
Deposit moves into the alert's pool
02
Notified
Responders inside the radius, area only
03
Accepted
Exact pin shared with them
04
Checked in
Meet code typed in person
05
Settled
“I'm safe”, or 30 min pass
Cancelled
Refund, minus 1 tUSDC per walker
Flagged
Nobody there: sender has 30 min to dispute
Help is paid for. False alarms aren't free.
Written into the alert contract, not left to a moderator.
| When | Then |
|---|---|
| You cancel before anyone accepts | Your full deposit comes back. |
| You cancel after someone set off | 1 tUSDC each for their walk, the rest back to you. |
| You tap “I'm safe” | Responders who checked in split the deposit. |
| You don't answer | It releases to them after 30 minutes. |
| Nobody was there | Responders who came keep the deposit; the sender's reputation drops. |
Where the deposit goes
A wider alert asks more people, so it costs a little more.

You approve a maximum once. Guardian takes no cut.
Who sees what
| Who | What they see |
|---|---|
| Everyone in your radius | Situation, an area about 100 m wide, your reputation, the deposit. |
| Responders who accept | Your exact pin and a walking route, until the alert closes. |
| The public chain | That an alert existed, its deposit and who was paid. Never your location. |
| A sponsoring campus | Anonymous counts per area and hour. Never who sent an alert. |
