How this service works
Provably-fair weighted lottery draw + house fee. Operator holds stakes; this never moves funds. ?tickets=addr:amount,addr:amount&fee_bps=500&round=1
Output
Returns the selected winner address chosen by provably-fair weighted randomness, the breakdown of prize amounts after the house fee deduction, and verifiable proof data tied to the committed round seed so anyone can independently verify the draw was fair.
