Simple idea
Will the price finish up or down?
Every coin runs parallel 1h and 24h rounds. The open price is the line to beat. You pick a side, send shielded ARRR into the pot, and when the clock hits zero the winning side splits the pot by time-weighted stake. No account. No claim button.
Go to marketsFrom bet to payout in one window
GamblARRR is a rolling Up/Down demo on Pirate Chain. You never fund a website wallet — you send on-chain yourself, and winners are paid back the same way. Soft closes and time weights exist so late “sure thing” snipes cannot drain the pool.
Send to the pot
Prepare a deposit memo, then send shielded ARRR from your Pirate wallet to the pot address with that memo. The memo locks your side and return address for this round. Betting stops before the oracle resolve (soft close).
Wait for settle
When the window ends, an independent price feed decides Up or Down. Winners share the pot by time-weighted stake — not raw last-second size. Payouts push to the address in your memo.
Fair play
Soft close + time weight — no free last-second snipes
Pure parimutuel pots are easy to game if you wait until the outcome is obvious. GamblARRR closes betting early and discounts late stakes so early risk still matters.
- Soft close. New bets stop before resolve — last 5 minutes on 1h rooms, last 15 minutes on 24h. The chart keeps running; the pot does not accept new memos.
- Time-weighted stakes. Full payout weight for the first third of the room (about 20 minutes on 1h, 8 hours on 24h). After that, weight decays progressively down to 0.05 at the last betting opportunity. Late sure-things claim almost nothing of the winners’ share.
- Why. Waiting for a locked-in direction should not harvest early bettors. Soft close removes the final seconds; time weight makes the rest of the late window expensive.
Fees & next pool
Small fees. Half fuels the next round.
There is a 1% fee on each bet and a 1% rake on the pot at payout. That is the whole fee story — no hidden spreads, no claim tax.
- Half of fees recycle into the next market as balanced house Up and Down bets. That seeds liquidity so early rounds are not empty.
- The other half goes to the platform treasury (operations).
The oracle
Why the price feed matters
Charts on the page are for watching the tape. Settlement is not the chart — it comes from Pyth, a public signed price network, at the time this market committed to.
- Strike locks at open. That open price is the line everyone is betting against.
- Resolve uses the same feed. Above the open → Up wins. At or below → Down wins. No human referee. No last-second “we decide.”
- Math is public. Anyone can recompute who should have been paid from the published deposits and outcome. Cheating on the math is easy to spot.
What you get
Why people use GamblARRR
No account
No signup, no KYC wall. Prepare a memo, send shielded ARRR, you are in the round.
Sealed while open
Side and size stay private during the window. The public board only shows volume and bet count.
Real chain notes
Pots, memos, and payouts live as shielded Pirate Chain notes — not a balance in our database.
Time-weighted pool
Winners split by stake × time weight. Early risk keeps full claim; late certainty pays almost nothing.
Always a next window
Markets auto-roll on 1h and 24h clocks. Soft close ends betting before resolve so the next room can open cleanly.
Paid to your address
Winners are pushed to the return address in your memo. No claim step, no leftover login.
