Upgradeability Risks
Meaning ⎊ The security vulnerabilities created by the mechanisms that allow smart contracts to be updated or modified.
Contract Storage Costs
Meaning ⎊ The significant gas fees associated with writing or updating data on the permanent blockchain ledger.
Sparse Bitsets
Meaning ⎊ An efficient representation of a bit array where most bits are zero, storing only active entries.
Variable Shadowing Risks
Meaning ⎊ Risks arising from naming conflicts that lead to confusion and logical errors during contract updates and inheritance.
Storage Gap Implementation
Meaning ⎊ Reserving empty storage slots in base contracts to allow for future variable additions without disrupting layout order.
Unstructured Storage Pattern
Meaning ⎊ Method of assigning variables to specific, hashed storage slots to avoid layout conflicts in upgradeable contracts.
State Transition Logic
Meaning ⎊ State Transition Logic provides the deterministic framework necessary for managing collateral and executing secure, trustless derivative contracts.
Mutex Locks
Meaning ⎊ Synchronization mechanism acting as a flag to prevent concurrent access and recursive execution of sensitive code blocks.
Gas Limit Manipulation Prevention
Meaning ⎊ Designing contracts to be resilient against attacks that exhaust gas limits or exploit gas mechanics for manipulation.
