Micro Donations Pool

# Micro Donations Pool – Solidity Smart Contract

A simple Ethereum-based donation pool that collects micro-donations from users and forwards all collected funds to a fixed charity wallet.

The contract is intentionally designed with no imports, no constructors, and no function input parameters.

## 🛠 Features

- ✅ Tracks individual donor contributions.

- ✅ Anyone can trigger a full withdrawal to the predefined charity via withdrawAll().

- ✅ Includes a basic reentrancy guard for safety.
