one wallet wins.

Reading the chain…
01Closing block hash
02Hash mod total holdings = remainder x
hash mod —= —
03Find x on the line
100 balls share out the line: hold 34% of it and 34 of them are yours. The tumbling is only a picture, the winner is fixed by the sum above. Tap the globe to shake it.
01 / How it works
One round, start to finish
A 26-second explainer. Pause it, scrub it, or jump between the steps on the right.
02 / Try it
Run a draw yourself
The wallets below are made up, but the rule is the real one: sort by address, lay end to end, take the hash modulo the total. Drag the slider to change your holdings and watch your stretch widen.

Each column is actual wins ÷ the wins expected from holdings. The more rounds you run, the closer every column gets to the dashed line: a wider stretch wins more often, but never more than its share.
03 / Rounds
Every round can be recomputed
Pick any round. Your browser reads the token's transfers straight from the chain, rebuilds every balance at that block, works out the winner and checks it against the payment recorded on chain.

05 / Rules
The rules, and where things stand
- Schedule
One round every 900 seconds, closing at :00, :15, :30 and :45 of every UTC hour.
- Eligibility
Hold at least 100,000 tokens (18 decimals) at the closing block. Nothing to do: holding is enough.
- Left out
The liquidity pool or inventory contract, the pot, the fee escrow, the zero address and the dead address.
- Randomness
The closing block's hash. The same inputs give the same winner on any machine.
- Your chance
Your holdings ÷ the holdings of every eligible wallet. More tokens, wider stretch.
- No double payment
Each round maps to one payment id, and the contract pays an id only once.

Known limits
- Randomness comes from a block hash. Whoever produces and orders blocks can, in theory, influence it.
- The operator submits the winner and the amount. The contract only guarantees that a round is not paid twice. It does not check the draw itself, which is why the recompute tool above is open to everyone.
- The operator can withdraw what no prize is waiting on. Each withdrawal is a public Withdrawn event on chain. The contract cannot see which prizes are still owed, so the operator's tooling works out that limit. What counts as unallocated depends on the payout rule, which is not decided yet.
- The payout fraction and its basis are not decided yet. Figures in the local demo are test inputs, not the production rules.
