CryptoDrawz is a weekly crypto lottery where a contract holds the money, a proof picks the winners, and every result is public.
Our promise
Three things, done properly.
One price. No surprises.
Every ticket costs $5, paid in the crypto you choose. The price is fixed in dollars, so what you see is what you pay, and what you win is what the pool says.

Buy ticketsThe round
Anatomy of a weekly draw.
Five steps, in this order, every week.
Step 1
A round opens
A new weekly round starts the moment the last one closes. The ticket price is fixed at $5.
Step 2
Tickets are sold
Each ticket gets its own lottery number, sent by email and trackable on the Track page. The prize pool grows with every ticket sold.
Step 3
Sales close
On Sunday at 20:00 UTC tickets for that draw close. Only tickets paid before then enter, so nobody can buy with knowledge of the result.
Step 4
Randomness arrives
We take one public random value from the drand beacon, published at the draw time. Nobody, including us, can know it beforehand.
Step 5
Winners are set
Fourteen different tickets are drawn from the random value and the ticket list. Winners are emailed and paid in crypto once they confirm a wallet address.
Fairness
Nobody picks the numbers. Not even us.
- The random value is public, so anyone can look it up themselves.
- Tickets are closed before the random value exists.
- The winner rule is public: one click recomputes who won.
- Finished draws are locked in our database and cannot be edited.
// fingerprint of the closed ticket list
ticketsHash = sha256(sorted tickets)
// public random value from drand
seed = sha256(randomness + ticketsHash)
// 14 different tickets, no repeats
for k = 0, 1, 2 …
ticket = sha256(seed + k) mod ticketsSold
skip if already picked
// pick #1 gets the grand prize
The money
Where every $5 goes.
No hidden cut, no rollover surprises. This is the whole split, and a tenth of it is for good.
The other 10%
A tenth of every ticket goes to good.
It supports good causes such as feeding people in hunger, helping people affected by war, donations and human-rights work. It also pays for improving CryptoDrawz and supports the developer who builds it.
Grand prize
50% of the pool
$2,250
Runner-up
10% each
$450 each
Lucky draw
2% each
$90 each
Example: a round with 1,000 tickets sells $5,000, of which $4,500 goes to the prize pool and $500 goes to good causes, improvements and the developer. Real amounts depend on how many tickets are sold.
Your odds
Do the maths before you play.
Move the sliders. Chances are exact, and we show them because we would rather you understand the game than be surprised by it.
Winners are 14 different tickets drawn without replacement, so this is exact maths, not an estimate. It assumes the round reaches the minimum size; below 50 tickets a round is cancelled and refunded.
- Prize pool (90% of sales)
- $4,500
- Grand prize (1 winner)
- $2,250
- Runner-up (3 winners)
- $450 each
- Lucky draw (10 winners)
- $90 each
- You spend
- $25
- Average return on that
- $23
“Average return” is what players get back in total, across many rounds. Any single round can pay you nothing.

FAQ
Questions, answered.
What is a crypto lottery?
A crypto lottery is a lottery where tickets are bought with cryptocurrency instead of cash. On CryptoDrawz a ticket costs $5, you pay with the crypto of your choice, and prizes are paid to the winners in crypto.
How do I play? Do I need an account?
No account and no password. Choose how many $5 tickets you want, enter your email, and pay with the crypto of your choice on the secure payment page. Your lottery numbers arrive by email as soon as the payment is confirmed.
How does the draw work?
Once a week ticket sales close (Sunday 20:00 UTC). We then take one public random value from the drand beacon, run by a group of independent organisations, and use it with the list of tickets to pick 14 different winning tickets: 1 grand prize, 3 runner-ups and 10 lucky-draw winners.
How do I know the draw is fair?
The random value comes from a public beacon that nobody controls and that nobody can know in advance. After every draw we publish the full ticket list, the random value and the winners on the Draws page, and you can recompute the result yourself in one click.
Where does my $5 go?
90% goes into the prize pool. The other 10% goes to good causes (like feeding people in hunger, helping those affected by war and human-rights work), to improving CryptoDrawz and to its developer. The split is in our Terms and every draw shows its prize pool.
What are my odds?
They depend on how many tickets are sold. With T tickets in the round, one ticket has a 1 in T chance at the grand prize and roughly a 14 in T chance of winning something. Use the odds calculator on this page to see exact numbers.
What if hardly anyone plays a round?
A round needs at least 50 tickets. If fewer are sold, the round is cancelled and everyone is refunded in full, and nothing is set aside from those tickets.
Who holds the money?
We do, as the operator. Prizes are paid to winners in crypto after they confirm a wallet address by replying to their winner email. We publish every draw so you can see exactly what was paid out.
What do I need to play?
An email address and some crypto. On the payment page you choose your coin (Bitcoin, Ethereum, USDT, USDC and more) and see the exact amount before you pay.
Is it legal for me to play?
That depends on where you live. Online lotteries and crypto games are restricted or banned in some countries and states. You must be 18 or older (or the legal age where you live) and it is your responsibility to follow local law. This is not legal advice.
