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 of your buy that enters the pool is one ticket, after the 1% fee, at the ETH price of that moment.
- A $25 buy prints 24.75 tickets, because the 1% fee doesn't count. Tickets can be fractions: half a ticket has half the chance of a whole one.
- 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. Your most recent tickets burn first. If you sell everything, all of your tickets burn.
Tokens someone sends you come without tickets. Only buying prints tickets.
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, which pays 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. When a ticket wins, two small fixed rewards come out of that 20%, at most 0.00005 ETH each. They go to whoever starts the draw and whoever finishes it. 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. There is no draw either if nobody holds a ticket.
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.
- During the freeze, which lasts about a minute, trading goes on. If the winning ticket's owner sold or sent any $JACK during the freeze, the ticket is void and the contract draws again with the same number. Tickets bought during the freeze join the next draw.
- The contract sends the prize automatically. If the transfer fails, the contract credits the prize to the winner. The winner can withdraw it at any time by calling
claim()on the Tickets contract from the winning wallet. Prizes never expire.
Anyone can start a draw or finish it. When a ticket wins, whoever started the draw and whoever finished it each get one of the small fixed rewards described above. 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.
Price discovery happens entirely on-chain, in the Uniswap v4 pool.
The first 2 minutes cost more, to stop sniper bots. The fee starts at 50% and falls to the normal 1% over 2 minutes. During those 2 minutes, all buyers together can take at most 3% of the supply every 12 seconds. Everything bots pay above the normal fee goes into the drawer.
06 · The printOne picture per draw
After each draw, an AI draws a one-of-a-kind print of that shift from its numbers: the hour the winner bought sets the light, the number of buyers sets the crowd, the prize sets the size of the main subject. It sees no wallet addresses. It has no access to the money and no say in the draw.
Everything written on the receipt comes from the shift's own data. Some lines are printed in heat-sensitive ink: move your cursor over the paper, or tap it on a phone, to read them.
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.
How do I know if I won?
The prize arrives in your wallet automatically, a few minutes after the draw. The live receipt shows the winning ticket, and on Past draws, "My wallet" lists every draw your address won.
Does a bigger buy give a better chance?
Yes, in direct proportion. $100 gives about 100 tickets, $1,000 about 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?
Yes. Tickets go to the wallet that receives the tokens, so smart-contract wallets and relayed swaps work. A router that keeps the tokens for itself passes no tickets on.
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?
You trust three things: the contracts, which are public, drand for the random number, and Robinhood, which runs the network that orders every transaction on Robinhood Chain.
