Anchor vs native Rust for Solana programs: how to choose
By Jakub Malarczyk, Founder, Orivions ·
- Anchor is the sensible default for most Solana applications: faster development, generated IDL and clients, and fewer account-validation mistakes.
- Native Rust gives full control over compute units, account layout and binary size, at the cost of writing every check by hand.
- Choose native for performance-critical primitives that will be called a lot, or when you need layouts Anchor makes awkward.
- Security depends more on the team and the audit than on the framework, but Anchor removes several common pitfalls by default.
- Ask any development company to justify its choice for your project instead of defaulting to what it always uses.
Every Solana program is Rust compiled to the Solana runtime. The real question is how much of the plumbing you write yourself. Anchor is a framework that generates most of it; native programs (sometimes built with lightweight libraries such as Pinocchio) write it by hand. Both are used in production by serious teams. The right choice depends on what your program does and who will maintain it.
What Anchor gives you
- Declarative account validation: you describe the accounts an instruction expects (signer, owner, seeds, mutability) and Anchor generates the checks.
- Discriminators: each account type gets a unique prefix, which protects against passing one account type where another is expected.
- An IDL: a machine-readable description of your program that generates TypeScript clients and makes integrations easier for other teams.
- Ecosystem and hiring: most Solana developers, examples, tutorials and auditors are familiar with Anchor, which lowers onboarding and review cost.
What native Rust gives you
- Compute efficiency: without framework overhead, instructions can use noticeably fewer compute units, which matters for programs called in hot paths such as AMMs and order books.
- Control over layout: you decide exactly how bytes are stored and parsed, including zero-copy patterns for very large accounts.
- Smaller binaries: which reduces deployment cost and can matter for complex programs close to size limits.
- No framework constraints: useful when your design does not fit the patterns Anchor assumes.
When to choose which
Choose Anchor for most applications: NFT and token projects, games, DAOs, payments, staking and the majority of DeFi applications where compute is not the bottleneck. You will ship faster, hire more easily and give auditors code they read every day.
Choose native Rust for performance-critical primitives that other programs will call thousands of times, for programs where every compute unit affects user costs or composability, or when you need account layouts the framework makes awkward. Make sure the team has shipped native programs before; the absence of guard rails is the point, and the risk.
A common middle path is to keep most of the system in Anchor and write one or two hot-path programs natively.
Security: does the framework matter?
Anchor does not make a program secure, and native programs are not insecure. Anchor removes several classic mistakes (missing owner checks, type confusion between accounts) unless you opt out of its checks. In native code, every one of those checks is your responsibility, so reviews take longer and depend more on experience. Either way, budget for an independent audit; see what drives the cost of a Solana audit.
What to ask a development company
Ask which approach they recommend for your program and why, what compute budget they expect per instruction, and which native or Anchor programs they have shipped to mainnet. A good team explains the trade-off for your case. More questions to ask are in how to hire a Solana development company, and you can compare verified teams on the Solana development companies page.
Frequently asked questions
Is Anchor or native Rust better for Solana development?
Neither is better in general. Anchor is the default for most applications because it removes boilerplate and prevents many account-validation mistakes. Native Rust makes sense when compute units, account size or binary size matter more than development speed, for example in high-throughput DeFi primitives.
Is Anchor less secure than native Rust?
No. Anchor makes several common mistakes harder, such as missing owner or discriminator checks. Native programs can be equally secure, but every check must be written by hand, so they depend more on the experience of the team and the quality of the audit.
Can I switch from Anchor to native Rust later?
Yes, but it is a rewrite of the program logic, and the account layout and client code may change. If you expect to need native performance, decide early or isolate the hot paths in a separate program.
