ONE BUTTON. A RANDOM TICKET. MAX LOSS = YOUR STAKE.
Each ROLL picks coin, side, knock-out line, take-profit and timer from the hash of the first HyperEVM block after your click, mixed with your wallet and roll number: seed = keccak256(blockHash, wallet, n). Neither you nor this page picks the block hash, and the seal on every ticket lets anyone re-run the draw. "Pick it myself" overrides the draw for the rows you set.
Every ticket is a real papertrade position opened from your own account by a trading key that lives only in this browser. The key can open and close positions; it cannot withdraw. It expires in 24 h. The one signature this page asks for is "RegisterSessionKey".
A blank TIMER row draws a random timer from 1 minute to 12 hours. NO LIMIT keeps the ticket open until take-profit, knock-out or your cash-out (after 24 h the trading key expires and you sign once more to cash out).
Take-profit and the timer also run on our server: when a ticket opens, this browser signs one "close this position" slip with its trading key and hands only that slip to the server, which sends it when the take-profit price or the timer is hit, even with this tab closed. The slip can only close that one position. Most high-leverage tickets are knocked out.
Papertrade does not pay a win in full: it keeps about 10% plus a larger cut on small moves, then a 2% fee. "PAYS ≈" and "WORTH ≈" use papertrade's payout formula; wins closed within ~10 bp of the entry are cut harder, so take-profit always sits at least 12 bp away. The receipt shows what papertrade actually paid. Odds are random-walk upper bounds, not promises. Not affiliated with papertrade. This page takes no fee.
