Provably Fair

The winning seed is committed (its hash published) when the round is created, before any tickets are on sale, and revealed once the draw settles. The operator cannot pick a seed after seeing who entered.

How it works

  1. While entries are open, tickets are sold sequentially and each wallet is capped: max 100 tickets per round.
  2. Before entries open the server generates a secret serverSeed and immediately publishes keccak256(serverSeed) as its commitment, alongside the public clientSeed. The seed is fixed before anyone buys, so the operator cannot grind it against the final entry set.
  3. When the round closes, one winning ticket number is derived by this formula, and the wallet holding that ticket takes the entire pot:
target(tier, attempt) = uint256(keccak256(serverSeed || clientSeed || drawId || tier || attempt)) mod totalTickets; winner(tier) = first entrant whose cumulative ticket count exceeds target; the single tier-1 winner takes the whole pot (legacy rounds paid up to 4 tiers; collisions with an earlier tier re-derive with attempt+1)
  1. At settlement the serverSeed, its hash and the winning ticket are revealed. Anyone can re-run the math in the verifier below and confirm the same winner. Legacy rounds paid up to 4 tiers, so verify those with winners=4.
