Inheritance-Based Storage Layouts
Meaning ⎊ Storage arrangement based on inheritance hierarchies which is highly susceptible to corruption during contract upgrades.
Unstructured Storage Patterns
Meaning ⎊ Design method using hard-coded storage slots to prevent layout collisions during contract upgrades.
Proxy Pattern
Meaning ⎊ A design strategy using a lightweight contract to delegate calls to an upgradeable implementation contract.
Storage Layout Preservation
Meaning ⎊ Discipline of keeping state variable order and types consistent across upgrades to prevent data misalignment.
Contract Metadata Registry
Meaning ⎊ On-chain or off-chain record tracking contract versions and implementation details to improve protocol transparency.
Upgradeability Proxy Security
Meaning ⎊ Proxy patterns allow smart contract updates while maintaining immutable data storage through secure, separated logic layers.
UUPS Pattern
Meaning ⎊ Upgrade logic residing in the implementation contract for a leaner proxy and lower gas costs.
Storage Collision
Meaning ⎊ Unintended overwriting of contract state variables due to mismatched storage layouts during proxy upgrades.
Storage Gap Implementation
Meaning ⎊ Reserving empty storage slots in base contracts to allow for future variable additions without disrupting layout order.
Proxy Contract Upgrades
Meaning ⎊ A design pattern allowing smart contract logic updates without changing the contract address or losing user state.
