This section outlines the protections embedded across protocol operations. *** ## **Smart Contract Hardening** Altura’s contracts incorporate multiple layers of reinforcement based on internal review and external audits. These include: ### **• Corrected Share Accounting** Ensures that minting and burning of shares cannot be exploited through rounding or precision attacks. ### **• Slippage & Value Protection** Deposit and withdrawal paths enforce value-consistency rules to guarantee users receive PPS-aligned outcomes. ### **• Oracle Validation Improvements** All PPS updates are validated against upper/lower bounds, timestamp thresholds, and movement limits to prevent incorrect data propagation. ### **• Enforced Paused States** All sensitive functions respect pausing controls, stopping execution during emergencies. ### **• Permissioned Transfers Only** Assets can only be transferred to pre-approved smart contracts and keeper EOA’s, eliminating arbitrary fund movement risk. ### **• Secure ERC20 Allowance Handling** Allowance operations follow strict patterns, preventing the class of errors commonly found in DeFi approvals. These adjustments form part of Altura’s long-term hardening strategy to ensure systemic security.
