  • The contract is quite simpl e. It divides the initial deposited amount into PAYOUTS parts. Every INTERVAL seconds after an initial offset the layer will be able to claim a payout.

  • Thanks! But how does "paidPayouts" get incremented? Because, as far as l see, when you subtract it in "duePayouts", it is 0, it is not incrementing in any way

  • When calling withdraw in this line paidPayouts += duePayouts, the variable paidPayouts is incremented by duePayouts.
