How it works

Before a round opens for betting, a random server seed is generated and the SHA-256 of it is published. The crash point is derived from that seed, so it is fixed before anyone can bet and cannot be changed afterwards. Once the round ends the seed itself is revealed.

Crash point formula

h   = HMAC-SHA256(serverSeed, roundId)
val = first 52 bits of h        (first 13 hex digits)
u   = val / 2^52                (a number from 0 up to 1)

crashPoint = floor(100 × 0.97 / (1 − u)) / 100
             capped at 32.00×, never below 1.00×

Why this is fair

• The seed's hash is published before you bet, so the crash point cannot be picked to suit your stake.
• The seed is revealed after the round, so you can check the hash matches and re-derive the crash point yourself.
• The 0.97 in the formula is the whole house edge: 3%, applied evenly, with no other adjustment anywhere.

Verify it

Take the revealed seed and the round number, compute the HMAC, and apply the formula. It must land on the published crash point.
