JACKPRINT
How itWORKS.
Buy $JACK, get tickets, keep them. Three times a day, one ticket wins most of the drawer.
THE RULES
- Every $1 of $JACK you buy prints 1 ticket.
- Your tickets stay in every draw for as long as you hold the tokens. Sell or send them, and the tickets burn.
- Three draws a day, at 05:00, 13:00 and 21:00 UTC. One ticket wins 80% of the drawer.
01 · TicketsHow you get tickets
Buy $JACK on Uniswap, on Robinhood Chain, in the official pool. You don't need to sign up or register for anything. Each dollar you spend on the buy is one ticket, counted at the ETH price at that moment.
- A $25 buy prints 25 tickets.
- Your chance is your tickets divided by all live tickets. 25 tickets out of 1,000,000 is a 1 in 40,000 chance per draw.
- Only buys in the official Jackprint pool print tickets. Buys on other pools or exchanges don't.
02 · Keep your receiptTickets last as long as you hold
Your tickets don't expire after one draw. If you still hold the tokens, they are in the next draw, and the one after, with no limit.
When tokens leave your wallet, the tickets bought with them burn. This applies to a sale on any pool, a transfer to another wallet, even your own, and a deposit somewhere else. If you sell half, half of your tickets burn.
Receiving tokens doesn't give tickets. Only buying does.
03 · The drawerWhere the prize comes from
Every buy and every sell in the pool pays a 1% fee:
| Part | Share of each trade |
|---|---|
| The drawer (the prize) | 0.75% |
| The team | 0.25% |
At each draw, the winner takes 80% of the drawer. The other 20% stays in for the next draw, so the drawer never starts empty. The team never puts money in and never takes money out of the drawer.
If 80% of the drawer is worth less than $5, there is no draw that shift: everything carries over to the next one.
04 · The drawHow the winner is picked, and why nobody can cheat
- At the draw time, the contract closes the register and freezes all tickets.
- It then waits for a random number from drand, published about a minute later. drand is a public randomness service run by about 23 independent organisations, including Cloudflare, the Ethereum Foundation and EPFL. Nobody, including us, can predict or change that number.
- The contract checks the number's signature itself, then picks the winning ticket from it.
- If the winning ticket's owner sold during the freeze, the ticket is void and the contract draws again with the same number.
- The prize is sent automatically. If the transfer fails, the winner can claim it on the site at any time. Prizes never expire.
Anyone can start a draw or finish it, and earns a small fixed reward from the drawer for doing so. Every past draw on the Past draws page shows the drand round and the transaction, so you can check it yourself.
05 · LaunchHow $JACK launches
There is no presale, no team allocation sold to buyers and no launchpad. The whole supply goes into the Uniswap pool at launch, and that liquidity is locked forever: nobody can withdraw it, including us.
The price starts at about 2 ETH for the whole supply and rises as people buy:
| Share of supply bought | Value of all $JACK |
|---|---|
| 0% (launch) | ~2 ETH |
| 50% | ~8 ETH |
| 80% | ~50 ETH |
| 90% | ~200 ETH |
The first 2 minutes are protected against bots. The fee starts at 50% and falls to the normal 1% over 2 minutes, and one buy can take at most 3% of the supply. Everything bots pay above the normal fee goes into the drawer.
06 · The CashierWho writes on the receipt
The Cashier is an AI. After each draw it writes the line at the bottom of the receipt, and it hides a few messages in the paper that only appear when you move your cursor over it, or tap it on a phone. It only sees numbers and wallet addresses. It has no access to the money and no say in the draw.
07 · QuestionsGood to know
Can I lose money?
Yes. $JACK is a memecoin and its price can fall. Each trade costs the 1% fee plus the pool's 0.3% liquidity fee. Most tickets never win. Only buy what you're fine losing.
Does a bigger buy give a better chance?
Yes, in direct proportion: $100 gives 100 tickets, $1,000 gives 1,000. Splitting a buy across wallets gives no extra chance.
Can I buy and sell right away to farm tickets?
No. Selling burns the tickets, and the fees on the round trip cost more than the tickets are worth.
Do smart-contract wallets work?
Not yet. Tickets go to the wallet that signs the transaction. Smart-contract wallets (account abstraction) and relayed swaps can't win in this version. Use a normal wallet.
Can the team change the rules?
No. The contracts have no owner, no pause button and no upgrade. The fees, the draw times and the launch rules are fixed in the code.
What do I trust?
The contracts, which are public; drand for the random number; and Robinhood, which runs the network that orders all transactions on Robinhood Chain.
