Reviewing a Solana smart contract for security requires checking Rust entrypoints and Anchor structs to enforce signer checks, validate program ownership, and ensure safe PDA seed derivation. This prevents unauthorized account access and fund drainage.

Anchor account deserialization requires verifying discriminator safety and type constraints to prevent type confusion. You must enforce account constraint correctness and validate init or realloc patterns to block unauthorized account data manipulation.

Yes, Solana program review verifies CPI reentrancy surfaces and compute-budget DoS bounds. It evaluates arithmetic overflow risks, PDA seed derivation correctness, and funds-handling invariants to prevent runtime exploitation and resource exhaustion.

Securing PDA seed derivation in Solana programs requires enforcing strict seed constraints and verifying authority boundaries in Rust code. Correct PDA derivation prevents unauthorized writes and protects program-controlled funds from being drained.

A Solana program security audit is needed when pull requests touch Rust entrypoints, Anchor structs, or code handling funds and authority boundaries. Enforcing threat-model assumptions before shipping prevents exploitable vulnerabilities in on-chain accounts.
