Specifics

Lottery Ticket Cost

1 ticket = 10 WMATIC

Lottery Entry Limit

No overall limit, but only buys of up to 30 tickets can be bought at a time through the web UI. Paying for one ticket will give users a random 4-digit combination, with each digit being between 1-9. For example: "1-9-3-2"

How to win?

To win the lottery jackpot (50% of the entire lottery pool), users need to match all 4 numbers on their ticket in the exact same order as the 4 winning numbers. If you donโ€™t match all 4 numbers, there is no need to worry: as long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.

Winning Ratio

  • Match all 4 numbers in the exact order: win 50% of the pot (or split the pot if more than 1 winner).
  • Match 3 numbers in the exact order: win or split 20% of the pot.
  • Match 2 numbers in the exact order: win or split 10% of the pot.

Lottery auto-Buyback allocation

The remaining 20% of the pot will be automatically used to perform buyback operations. In the event that no participants were able to match 3 numbers on any draw, the 20% allocated to auto-Buyback will still be used accordingly. Practical example: If the final 4 winning numbers are "1-9-3-2":
  • "2-3-9-1" = matches 0 numbers.
  • "1-9-3-2" = matches all 4 numbers.
  • "1-9-2-2" = matches 3 numbers.
  • "2-3-3-2" = matches 2 numbers.
  • "1-2-1-2" = matches 2 numbers.

Lottery phases

Each full lottery session is completed every 12 hours, with 2 sessions taking place each day. Lottery timing and schedule follows:
  • 00:00h to 11:00h (UTC)
  • 12:00h to 23:00h (UTC)
  • 00:00h to 11:00h (UTC)
  • 12:00h to 23:00h (UTC)
An example of a lottery session starting at 00:00h (UTC) follows:
Phase 1 - Buy Tickets (00:00h to 11:00h UTC) - Allocated time to buy tickets: You have 1 hour to buy tickets. - The lottery jackpot will accumulate at the top of the page with each ticket bought. - Users will receive a ticket (comprised of 4 digits) for each 10 WMATIC paid.
Phase 2 - Lottery Draw! (11:00h UTC) The 4 winning lottery numbers are drawn and will appear on the page. Each participantโ€™s winnings will be automatically calculated based on their ticket numbers and shown on the page. Users can claim winnings if they have any. Transparency: Users will also be able to see the lottery results: How many users matched all 4 numbers, 3 numbers, and 2 numbers.
Phase 3 - Winner announcement and Celebrations (11:00h to 12:00h UTC) If you won, congrats! Feel free to share it and brag with your friends or in WorldSwap's social media and community groups. All winners will be announced in WorldSwap's Announcement Channel. Next lottery phase starting 1 hour after the close of the previous round.

Ticket number drawn methodology

The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, there is an extremely low chance that anyone is able to determine the 4 winning numbers ahead of time.

Methodology and calculation:

  • The 1st lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the number of participating users at the entry deadline.
  • The 2nd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the total pooled wmatic balance at the entry deadline.
  • The 3rd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
  • The 4th lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the block difficulty at the entry deadline.
