☕ Subscription-System-Core Smart Contract

This repository provides a smart contract framework that enables users to support creators by "buying a coffee"—a metaphorical transaction where users send Ethereum (ETH) along with a personal message. The project leverages Solidity and Hardhat for smart contract development and testing, ensuring compatibility with Core Blockchain networks.
