How Luckereum works.Trade, hold, win.
Every coin launched here carries its own pot. Trading fills it, a clock decides when it's drawn, and Chainlink decides who wins.
- 1/4
Launch
A creator launches a coin, picks its pair (ETH, USDC, PEPE, TSLA…) and its game. Supply is fixed at 1B, there is no owner.
- 2/4
Trade
Every trade is in the pair and pays 1.5%. 1% goes straight into the coin's pot, on the curve and on Uniswap.
- 3/4
Ticket
Every buy made here above the coin's minimum ticket (about $2.50 of its pair) is a ticket in the current round, weighted by what it spent.
- 4/4
Draw
When the round's clock runs out, Chainlink VRF picks the winners. Prizes are paid in the coin's pair.
Three games. The creator picks one.
Jackpot
One ticket takes 80% of the pot. 20% stays to seed the next round.

Mega
Each draw hits one time in four. A miss rolls the whole pot over, so it keeps growing. A hit pays one ticket 90%.
90% to winners · 10% seed
Rounds last 1 hour, 6 hours or 24 hours, chosen at launch. The clock starts with the round's first ticket, and a draw needs a minimum pot of about $5 in the coin's pair (0.002 ETH for ETH coins).
Hold to win.Sell, and your ticket burns.
A ticket only wins if the wallet that bought it hasn't sold or sent a single token since. Each Luckereum coin counts the transfers every wallet sends; a ticket remembers that count, and a ticket whose wallet has moved coins since is skipped. A skipped ticket is taken out of the draw and the pick is made again among the remaining tickets, so sold tickets can't block a prize. A prize nobody can take rolls into the next pot.
Receiving coins never burns a ticket. Zero-amount transfers don't count, so nobody can burn your ticket for you.
Fair, and you can check it.
Chainlink VRF v2.5 picks every winner
When a round ends, anyone can start its draw: the round closes (new tickets go to the next one) and the jackpot contract asks Chainlink's VRF wrapper for a random number, paid in ETH: from the pot for ETH coins, from the ETH draw vault for every other pair. Chainlink answers with a number and a cryptographic proof checked on-chain. Nobody, including us, can know or choose it in advance.
Winners are picked among the round's tickets, weighted by what they spent in the pair, without replacement: a ticket can win once per draw. A round closes the second its clock runs out; tickets bought after that go to the next round. The random word, the tickets and the result are all public: anyone can recompute a draw.
No prize can get stuck
If Chainlink hasn't answered 6 hours after a request, anyone can ask again; every request stays valid and the first answer to arrive is used, so a retry can never throw a result away. Only after 7 days without any answer can the draw fall back to the hash of a future block: weaker randomness, kept as a last resort so a pot can never be stuck.
The VRF fee is capped at 0.01 ETH per request (and 10% of the pot for ETH coins), so nobody can drain a pot by drawing at a silly gas price. Prizes are credited to winners in the pair and pushed to their wallets automatically; anyone can trigger a payout, and it only ever pays the winner. A winner who cannot receive the pair (a blocked address) claims it to another wallet.
Where the 1.5% goes
- 1%
- The coin's pot. Every trade, on the curve and on Uniswap v4, from any app.
- 0.25%
- The coin's creator, forever.
- 0.25%
- Luckereum, for keepers, Chainlink fees and development.
There is no transfer tax: moving coins between wallets costs nothing but gas.
From curve to Uniswap
800M tokens are sold on a bonding curve in the coin's pair. When it has raised about $12,000 of it (4.5 ETH for ETH coins) it graduates: 98% of the raise and the matching reserved tokens open a coin / pair Uniswap v4 pool at exactly the curve's last price. The position is minted to the dead address, so the liquidity is burned and can never be pulled.
The pool's hook keeps charging 1.5% on swaps from any router, so the jackpot never stops. Buys made on Luckereum keep earning tickets.
The contracts.
Open source and immutable: no proxy, no upgrade. The launchpad's owner can only change where protocol fees go, pause new launches and choose which pairs new coins can launch with. It cannot touch curves, pools, liquidity, pots, prizes, creator fees or any existing coin.

Questions.
Buy a coin on Luckereum for at least its minimum ticket (about $2.50 of its pair, 0.001 ETH for ETH coins). That buy is your ticket for the round in progress, weighted by what you spent. Then hold until the draw.
