## Storage Gap Implementation

Storage gap implementation involves reserving unused storage slots in a base contract to accommodate future variable additions. When a contract is inherited by an implementation, the storage layout must remain consistent across versions to avoid corruption.

By defining an array of unused variables at the end of the contract, developers create a buffer. If a future update requires adding a new variable, the developer can replace one of the reserved slots with the new variable without shifting the existing storage layout.

This practice is crucial for maintaining compatibility in upgradeable systems. It provides a safety net that prevents accidental data displacement during contract upgrades.
