Provably fair

Each round, the operator commits to a hidden seed by publishing keccak256(seed) on-chain before betting opens. Once betting closes, the seed is revealed — the contract checks it against the earlier commitment, so it couldn't have been changed after seeing anyone's bet.

The crash point is computed from the revealed seed with a fixed, public formula (same family used by well-known crash games): crash = min(500, 100 × 2⁵² / (2⁵² − (seed mod 2⁵²))), with a 1-in-33 chance of an instant 1.00x. Anyone can recompute it from the seed in the history table above and confirm it matches — call crashPointFromSeed(seed) directly on the contract.

The live multiplier itself is just 1.00x + 0.0125 × seconds² — a public formula, not a secret. Clicking Cash Out sends a real transaction, so its timestamp is fixed by the blockchain, not by anyone's word. Once revealed, the contract checks whether that timestamp's implied multiplier landed under the crash point — deterministically, from data nobody can alter after the fact. The operator privately knows the crash point during the live window (a public chain can't hide a number while it needs to stay hidden), but never decides who wins — the math does.
