One entry is 2,500,000 $CUP, sent to the burn address 0x000000000000000000000000000000000000dEaD. The tokens are gone; nobody holds them. One entry per wallet per cup. A burn of at least one entry counts, even if you didn't use this site, as long as it lands more than an hour before the cup closes. Entries shut 60 minutes before the close, so nobody can enter late, make one trade and take the pot. The $CUP contract is 0xD475211BEF5dCc03B4c8c864f90bde331AF80ba3 and nothing else.
Every price is the Chainlink feed for that Stock Token, read live at fill time, multiplier included. A fill records the round id it used. If a feed is older than 1500 minutes or the token's oracle is paused for a corporate action, that token is frozen: no new orders, existing positions keep their last valid mark.
Some cups trade crypto instead of stocks. BTC, ETH, LINK and ENA are marked at their Chainlink feeds on Robinhood Chain, exactly like the stocks. Robinhood Chain meme tokens (PONS, CASHCAT, TENDIES and the others listed on the cup) have no feed, so they are marked at a 30-minute time-weighted average price read from their deepest Uniswap v3 pool, converted to USD with the Chainlink ETH/USD feed. A fill records the block it was read at. If the pool can't return the average, the name is frozen.
Virtual $100,000, long only. Buys are sized in USDG, sells in tokens. Every fill costs 10 bps of virtual cash, a paper fee so the book behaves like a real one; nothing is charged to you. No name may exceed 40% of your book after a buy. 20 trades per cup. Trading locks for the last 15 minutes. Orders are signed messages from your wallet, not transactions, so there is no gas.
At the close, every book is marked at the last valid Chainlink round at or before the close time. Rank is by book value. A book with no fills is ranked but not paid; its prize position passes to the next book that traded. Ties split the combined prize. The pot is split 35% / 20% / 12% across the top three and 33% evenly across places four to ten. With fewer than 20 entries the top three take 50 / 30 / 20. For a cup that posted a prize, it is sent from the published prize wallet within 48 hours of settlement. The round ids used for every mark are published with the results.
Each cup's prize is set by the organiser and posted on that cup before it opens. It is not a share of entries or fees, entry burns don't fund it, and no prize is promised for any cup that hasn't posted one. Prizes can differ in size and asset from cup to cup, and there may be cups with no prize at all.
