Aztec (AZTEC)

Overview

Aztec is an Ethereum Layer 2 network built for private applications. Its token, AZTEC, helps operate and govern that network. Developers can use Aztec to build programs that keep selected details confidential while still proving that the programs followed their rules. This approach is called programmable privacy: an application can choose what users reveal and what they keep private. Aztec’s mainnet Alpha supports private smart contracts and user transactions. (aztec.network)

On many blockchains, anyone can inspect account activity and contract data. Aztec offers another way to build. A payment app, for example, can keep personal details private while producing a mathematical proof that a payment was processed correctly. AZTEC connects that technology to the people who run the network, the users who pay fees, and the holders who vote on changes. (aztec.network)

History & Team

From private assets to a general-purpose network

Aztec began in 2017. Its founding group included Zac Williamson, Joe Andrews, Tom Pocock, and Arnaud Schenk. Their early work explored private financial activity on Ethereum. In 2018, the team demonstrated a way to create and transfer private assets. Later research helped produce PLONK, a zero-knowledge proving system that influenced Aztec’s next products. (aztec.network)

The team went on to develop zk.money for private payments and Aztec Connect for private interactions with Ethereum finance applications. Both services closed in 2023 as work shifted toward a decentralized network that could support many kinds of private programs. Paradigm led a $17 million Series A financing in 2021, and a16z crypto has also publicly described its investment in Aztec. (aztec.network)

Aztec opened its public testnet in May 2025. The Ignition Chain began operating in November 2025, establishing decentralized block production before private smart-contract execution was enabled. In March 2026, a community-approved upgrade brought the network into its Alpha phase. (aztec.network)

Technology & How It Works

Private execution and public verification

Aztec uses zero-knowledge proofs, which let someone show that a calculation followed its rules without revealing all the information used in it. For a private transaction, sensitive steps run on the user’s device. The device creates a proof, and the network checks that proof. Public parts of a transaction can also run on the network. The resulting activity is settled through Ethereum. (aztec.network)

Developers write Aztec smart contracts using Noir and the Aztec.nr framework. They can mark functions as private or public and combine the two within an application. This matters because useful programs often need both: a trading service might keep a user’s identity private while making some market information visible to everyone. Aztec also lets private contracts interact with one another, so builders can create more than isolated private transfers. (aztec.network)

The people and software behind a block

Aztec separates several jobs. Sequencers propose blocks and help validate transactions. Provers create proofs for groups of blocks. Ethereum contracts record and verify the rollup’s results. This division lets users carry out private work locally while a wider set of participants maintains the shared network. (aztec.network)

Privacy also changes what a wallet must do. An Aztec wallet tracks encrypted records of a user’s private activity, finds records it can read, and helps generate proofs. These tasks go beyond the usual work of signing a transfer on a public blockchain. (docs.aztec.network)

Tokenomics & Utility

Supply, fees, and network rewards

AZTEC is an ERC-20 token on Ethereum. Its documented initial supply is 10.35 billion tokens. The token has three main roles: it supports staking for block production, gives holders a route into governance, and provides the asset used to fund transaction fees. Aztec’s 2025 open auction offered up to 1.547 billion tokens, or about 14.95% of the initial supply. (docs.aztec.network)

Fees use an Aztec network balance called Fee Juice. A user deposits AZTEC from Ethereum into a portal and receives Fee Juice on Aztec at a one-to-one rate. Fee Juice pays for transactions; it cannot be transferred between Aztec accounts or withdrawn by a user back to Ethereum. Applications can also arrange to pay a user’s fee through a fee-paying contract. (docs.aztec.network)

Sequencers stake AZTEC to become eligible to help produce blocks. Token holders can also delegate stake to an operator. Network rewards are shared between sequencers and provers, with 70% of checkpoint rewards assigned to sequencers and 30% to provers under the documented reward design. Tokens set aside for these rewards enter circulation as participants earn them. Governance can adjust reward parameters, while the protocol places a cap on later token issuance. (docs.aztec.network)

Governance gives the token a further purpose. Eligible holders can vote on proposals concerning upgrades and network settings. Aztec uses a staged process in which block producers first signal support for a proposal and token holders then vote. (docs.aztec.network)

Ecosystem & Use Cases

Aztec’s design suits applications that need shared rules without making every user detail public. Possible uses include private payments, financial applications, identity checks, games with hidden information, and tokenized assets. A builder can decide which facts an app must publish, rather than applying one privacy setting to everything. (aztec.network)

The ecosystem includes working projects with different purposes. Azguard is a wallet for Aztec accounts. Shield connects Ethereum and Aztec. Nyx offers private financial activity, while RavenHouse and Dark Forest Aztec show how the network can support collectibles and games. These examples show that programmable privacy can serve everyday account activity as well as more specialized applications. (aztec.network)

Developer tools are another part of the ecosystem. Noir helps programmers write the logic behind proofs, while Aztec.nr and Aztec.js help them build and connect applications. Together, these tools give builders a way to work with private functions without designing every cryptographic component themselves. (aztec.network)

Advantages & Challenges

What the design makes possible

Aztec’s main advantage is choice. Developers can combine private data, identity, and computation with public functions where those are useful. Local proof generation keeps private inputs on the user’s device during that process. Decentralized sequencers and provers give the network separate groups responsible for building and proving blocks. (aztec.network)

The same design creates practical challenges. Wallets must manage private records as well as keys. Proof generation takes computing work, and developers must plan how private and public functions fit together. Aztec is also progressing through its Alpha stage: upgrades can change the environment in which applications run, making state migration an important task for builders. These are engineering questions that will shape how easily more people can use the network. (docs.aztec.network)

Where to Buy & Wallets

AZTEC is available on Coinbase, Kraken, Gate, and Uniswap, among other platforms listed by Aztec. The token lives on Ethereum, so an Ethereum wallet that supports ERC-20 assets can hold and transfer it. Its official Ethereum contract address is 0xA27EC0006e59f245217Ff08CD52A7E8b169E62D2. (aztec.network)

Azguard is a browser-extension wallet for using Aztec applications. It creates Aztec accounts, connects to apps, and generates transaction proofs on the user’s device. The Aztec team also provides a command-line wallet aimed at developers. Holding AZTEC on Ethereum and using an account on Aztec are distinct activities: the Fee Juice portal links the Ethereum token to fee spending on the Layer 2 network. (docs.aztec.network)

Regulatory & Compliance

Aztec’s token sale and applications operate within rules that differ by jurisdiction. The Aztec Foundation published a white paper under the European Union’s Markets in Crypto-Assets framework, known as MiCA. Under that framework, notifying authorities about a crypto-asset white paper does not mean the authorities have approved it. The Foundation’s sale materials also set participation and sanctions-screening conditions; its UK notice excluded UK residents from that token sale. (aztec.network)

Aztec’s technology lets application builders choose what information to disclose. That can support designs in which a user proves a required fact without posting all their personal information on a public ledger. The checks an application needs still depend on what it does and where it operates. (aztec.network)

AZTEC has no established general halal or Shariah-compliant classification in Aztec’s published token materials. A religious assessment would need to consider how the token is acquired and used, including the terms of any staking arrangement or financial application. The network can host different activities, so an assessment of one app would not automatically describe every use of AZTEC. (docs.aztec.network)

Future Outlook

Aztec’s next stage depends on network performance and upgrades approved through governance. Its stated path from Alpha to Beta uses targets for transaction speed, user experience, and uptime rather than a fixed launch date. Work on wallets, proof generation, and application development will also affect how widely its privacy features can be used. (docs.aztec.network)

The Alpha V5 upgrade in July 2026 showed this process in action: token-holder governance approved changes that shortened private-transaction proving times and improved block production. Future progress will be measured not only by technical upgrades, but by whether developers turn those tools into applications people can use. (aztec.network)

Summary

Aztec brings programmable privacy to an Ethereum Layer 2 network. Users can keep selected information private while proofs help the network verify that its rules were followed. AZTEC ties together fees, staking rewards, and governance. Its place in the crypto ecosystem rests on a clear idea: useful blockchain applications may need both public verification and room for private activity. (aztec.network)
