🎠 Magic Carousel Exploit

This repository contains the full exploit code for the "Magic Animal Carousel" challenge from Ethernaut, developed to demonstrate a high-level vulnerability chain involving:

• Precise buffer overflow via bit overflow
• Destructive XOR data corruption
• Infinite loop creation through circular crate references
• Invariant violation in storage layout (bit-packing mismanagement)

The exploit is written in Solidity (v0.8.28) and can be run in Remix or integrated into a Foundry/Hardhat environment.
