Security guide

Rust Smart Contract Security

Rust smart contract security guide covering Solana, Anchor, CosmWasm, NEAR, Substrate, serialization, unsafe Rust, CPI, and state validation.

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.

Next step

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

Need an auditor to review the actual code?

Send the repository, target chain, and timeline. The audit scope should be specific enough to review and quote.
