Rust does not remove protocol risk
Rust prevents many memory-safety issues, but smart contract exploits usually target validation, authorization, state transitions, arithmetic, account models, and protocol logic.
Solana and Anchor review points
Solana programs need careful checks around signer validation, ownership, PDAs, account confusion, initialization, close flows, CPI targets, remaining accounts, and serialization.
CosmWasm and NEAR review points
CosmWasm audits focus on entry points, storage, migrations, IBC callbacks, replies, and permissions. NEAR adds asynchronous promise behavior, access keys, storage staking, and predecessor account validation.
Substrate and protocol Rust
Substrate runtime review covers pallets, origins, weights, hooks, storage, runtime upgrades, XCM, and economic invariants that may not look like typical smart contract code.
Dependency and unsafe-code risk
Auditors should review unsafe blocks, cryptographic code, serialization libraries, supply-chain assumptions, and performance changes that alter security behavior.

Use this guide to improve your scope, then request a review when the contracts, documentation, and tests are ready for a frozen commit audit.
