## Storage Slot

A storage slot is a specific 32-byte location in the persistent storage of a smart contract where data is held. The Ethereum Virtual Machine uses a key-value store where variables are mapped to these slots based on their order of declaration.

In upgradeable contracts, maintaining the exact order and layout of storage slots across different versions of the implementation contract is vital. If a new version of the logic changes the layout, it can overwrite existing user data, leading to catastrophic financial loss.

Consequently, developers must use specialized patterns like unstructured storage to prevent storage collisions during contract upgrades.
