Noir

Private applications, easy to build.👽 Noir is an open-source programming language for building ZK applications, with familiar Rust-like syntax.

Building a frontend for your Noir app? Stop hand-writing the bindings.

noir_codegen generates TypeScript directly from your exported Noir library functions, so calling a circuit from your website is as simple as calling any typed function.

Change the circuit, regenerate, and the compiler flags every call site that no longer matches.

@crypto_dev_1 Built on Noir! This is great!

How Legato works:

• Employer deposits salaries into a privacy asset pool
• Employee withdraws anytime, privately from pool

Built with @NoirLang, @solidity_lang, and @tempo testnet.

[Zatoshi @Zac_Aztec]

This is brilliant demonstration of the power of @NoirLang . It turns "privacy" from a narrative meme into reality.

@savio_sou @ZKPassport And soon to be one of the most impactful zk apps over the coming years.

[Noir @NoirLang]

Your passport proves who you are.

It also overshares: full name, date of birth, document number, each handed over just to prove you’re over 18.

@zkpassport fixes the overshare. Prove specific facts from your passport without revealing the rest.

As we've seen time and time again, teams pick Noir to ship one product and end up expanding what everyone can build.

What many don’t know is that the @ZKPassport team built a huge chunk of Noir’s mobile proving stack along the way, including noir_rs, Swoir for iOS, and noir_android.

Proving identity on a phone meant making Noir run natively on phones. As a result, the whole ecosystem benefits.

Two commands stand between your Noir circuit and any EVM chain:

bb write_vk -b ./target/program.json -o ./target --oracle_hash keccak

bb write_solidity_verifier -k ./target/vk -o ./target/Verifier.sol

That’s a deployable Solidity verifier contract. Your proofs, verified onchain, on the chains your users already live on.

No install needed — it ships with Nargo (noirup v0.1.4+).

noir-profiler opcodes --artifact-path ./target/program.json --output ./target

A concrete win from the docs: a program zeroing out an array past a dynamic index.

The flamegraph showed dynamic array writes dominating the cost. Moving the writes into an unconstrained function and asserting the result in-circuit: 387 → 284 ACIR opcodes. The flamegraph told you exactly what to fix.

Honoured to be building with @AztecNetwork 🤝

This collaboration is a testament to their world-class engineering — Noir is an outstanding DSL, and the thriving Aztec ecosystem is what makes privacy-first identity truly scalable.

This collab is also a quiet nod to the zkKYC logic we’ve been grinding on for years. Honestly? It’s the best work we’ve ever done — and it’s becoming the foundation for how Web3 identity actually works.

Tomorrow, we’ve got something else to share. Just a little something. 👀

Privacy without identity doesn’t scale. Identity without privacy shouldn’t exist. Compliant privacy is how the real world comes on-chain.

Noir gets the top billing in this week's Aztec Weekly Recap for our announcement with @solanapayments! 👽

Check it out below 👇

[Aztec @aztecnetwork]

This week on Aztec: Noir goes cross-chain to Solana, operator survey results, new Wonderland collabs, and education to get you building in under a minute. Here's the recap.

[Noir @NoirLang]

Noir is now directly available on @solana!

This is another step on the path towards bringing zk privacy to the masses.

[Solana Payments @solanapayments]

Privacy on @solana comes as three modular options you combine by use case:

- Confidential balances, built into the token program.
- Contra, a state channel for thousands of private transactions with mainnet liquidity intact.
- @NoirLang, @aztecnetwork's zk language, now coming to solana.
