Satellite hunt · Robinhood Chain
A bag is hidden somewhere on Earth. Guess where.
Every 10 minutes a new satellite picture. Closest pin within 25 km takes the bag. Unfound bags burn.

Rules of the hunt
- Every 10 minutes one bag goes live: a satellite picture with no coordinates. Drop a pin on the world map where you think it is.
- When the round closes, the closest pin within 25 km wins the bag; hold 200,000 of the coin being hunted to be eligible.
- Bags nobody finds are burned.
01 · How it works
Three moves, all on chain.
-
01
Launch in one transaction
A creator launches a coin on Pons and hides part of the first buy as 4 to 64 bags, in a single transaction. The vault stores a commitment to every location before the first round starts, so nobody picks the spot.

Guess

When the round closes, the closest pin within 25 km wins the bag; hold 200,000 of the coin being hunted to be eligible. Pins are free signatures, and the relayer pays the gas to send the bag.

03 · The vault
What the contract lets us do, and what nobody can.
The owner can
- Pause new settlements (claims) in an emergency, e.g. a suspected warden key leak; pausing moves no tokens and burns still run, so bags left unsettled when a paused hunt closes are burned, never returned.
- Replace the warden, only after a public 48-hour delay.
- Return tokens sent to the vault by mistake, limited to the amount above what open hunts are owed.
Nobody can
- Withdraw hunt rewards: tokens leave only to a winner named in a warden voucher, or to the burn.
- Move or resize a bag: locations come from the committed seed and the opening block hash, sizes are fixed when a hunt opens.
- Stop a burn: anyone can sweep a closed hunt, even while settlements are paused.
- Charge a fee: there is no fee and no switch to add one.
- Reuse a voucher: each bag settles once.
Check every line against the source on the proof page, which also re-derives any revealed bag location in your browser.
04 · Honest limits
Where the design is weaker than it looks.
- The warden (our server) knows each bag's location before the round ends. It cannot move tokens without a signed voucher, and every pin, voucher and seed is public, so a wrong winner is provable after the fact, not impossible beforehand.
- If our server is down, no voucher is issued: unsettled bags burn when the hunt closes. If only the relayer is down, winners can submit the published voucher themselves.
- Imagery is a 2016 cloudless mosaic at 10 m; some bags sit in featureless desert or forest. The zoom-out stages help, and bags nobody finds burn.
- A hunt's coin can be worth very little; a bag is a share of the creator's own first buy, nothing more.
05 · For creators
Launch a coin. Hide it on the planet.
Estimate what one launch transaction buys, using the Pons curve (1.68 ETH virtual reserve, 1,000,000,000 supply, 1% curve fee, 0.0005 ETH launch fee). The launcher quotes the exact numbers before you sign.
