paymentsDistributor

Overview

The PaymentDistributor contract is an Ethereum smart contract designed to automate the process of accepting and distributing Ether payments. The main functionality allows a sender to submit a payment that will be automatically distributed among a seller, a referrer, and the website's address.

Key Features:

• Ownable: Inherits from OpenZeppelin's Ownable, making certain functions accessible only by the contract's owner.
• Website Fee: Takes a percentage fee from each payment for the website's address.
• Referrer Fee: Optionally assigns a fee for a referrer if the address is not the zero address.
• Safety Checks: Ensures percentages do not exceed 100% and validates non-zero addresses for sellers.
