Aztec is the leading platform for unstoppable private apps: a decentralized Ethereum L2 with no gatekeepers.
Amounts and counterparties stay between you and the person you paid.
See a payment exampleThe pool stays public and priced. Your position and your strategy stay yours.
Private and public statePay for inference privately, so the provider answers the request without learning who sent it.
Explore the appsShow your tax authority your gains, without revealing how many shares you hold or your trading activity.
See selective disclosureEvery private app on Aztec runs on them: composable contracts with privacy built in, deployed without permission.
You decide which functions are private and which are public. Everything is handled for you under the hood.
Explore smart contractsRated Stage 2 by L2BEAT, with no centralized sequencer and no single party in control. Settled on Ethereum.
Explore the blockchainRust-like syntax for zero-knowledge programs, on Aztec or anywhere.
Explore NoirBuilt to keep running independently of its creators, with no centralized sequencer that could stop the apps on it. Secured by Ethereum.
01 · Your device
Private functions run here, and a proof says the rules were followed.
02 · Aztec Network
Sequencers order transactions and provers prove each epoch. Both roles are open.

Ethereum verifies the proof. Private inputs are never published in the clear.
A strategy game played in the dark. Explore a procedurally generated universe and hold planets nobody else can see, with the fog enforced by private state.
Private Inference is a private AI chat and API that gives you GPT, Claude, Gemini and open models under one balance, without storing your chats. Pay privately with cUSDC on Aztec or Zcash and keep prompts encrypted in a secure enclave.
A decentralised exchange that keeps the trader private. Your identity and strategy stay with you; the market stays public enough to price.
The platform for unstoppable private apps is live. Major security upgrades, 2x speedup in private transactions, a growing ecosystem of private apps, and a bold new identity mark Aztec's next chapter.
How Aztec protects private data from quantum attacks today, and our plan for full post-quantum security.
Aztec is three layers. Noir is the language for writing programs that can be proved. The contract framework splits execution between your device and the network. The rollup underneath is run by thousands of independent sequencers. This is how they fit together.
Every privacy system has an off-switch. What matters is who holds it, and on most networks the answer is an operator. Here is why Aztec was built so that nobody does.
Contributors identified a critical vulnerability in Aztec's V5 Alpha proving system, the kind of finding Alpha testing exists to surface, with the fix planned for V6.
Dark Forest Aztec, built by DFArchon, ports the classic zero-knowledge strategy game to Aztec, where your home coordinates and fleet movements live as private notes that stay hidden even as the universe runs onchain. Round One is live as an alpha: explore a dark map, capture planets, hunt artifacts, and try to find your rivals before they find you.
Every transaction on Aztec costs gas, and gas on Aztec works in two ways: public or private. This article covers how gas is paid, why it has a public and a private mode, and how you handle it whether you're working through an app or a browser extension wallet.
Alpha V5 reduces private-transaction proving times by over 2x, drops average block production time from 14 to 6 seconds, stabilizes the network with major security updates, and launches the first wave of privacy-preserving apps.
Aztec was built so that one transaction can carry two aspects. A private half that executes on your own device, and a public half that executes on the network.
