Smart Contract & Program Architecture Review

Overview & Methodology

Developing robust on-chain programs requires strict separation between executable instructions and mutable data accounts. Security and performance vulnerabilities in this paradigm often stem from unvalidated account ownership checks, improper signer verification, or excessive compute unit consumption during deserialization.

The Smart Contract & Program Architecture Review is a deep technical evaluation of your codebase’s architectural structure before you enter formal external audits or public testnet phases.

Technical Focus Areas

1. Account Validation & Signer Verification: Verifying that all instruction handlers validate account keys, owner program IDs, and required cryptographic signatures prior to executing state changes.
2. Compute Unit (CU) Budget Optimization: Identifying computationally heavy operations, reducing serialization overhead by utilizing zero-copy data accounts, and benchmarking transaction execution costs.
3. Cross-Program Invocation (CPI) Safety: Verifying Program Derived Address (PDA) signing logic, checking seed derivation robustness, and ensuring reentrancy-safe call patterns.
4. Data Space Allocation & Realloc Safety: Reviewing dynamic account reallocation boundaries to prevent data truncation or storage corruption during program upgrades.
