In   Tornado  After Cash, the privacy circuit comes at a time of crisis of confidence. Recently, Using UTXO model and privacy proof. Layer 2    Aztec Network Expansion announced completion by   a16z  crypto lead investment, A Capital investment of $100 million B round financing. Aztec Network has been running on the network before. Paradigm  It has raised nearly $17 million in Series A funding. Co-founder of Aztec after securing funding. Andrews said the money will be used to hire more engineers around the world to build the network.

Aztec is a zero-knowledge Rollup built with a privacy-first architecture, allowing users to access the applications that Layer 1 wants to use under the condition of full privacy protection. Its product system is PLONK proof system based on the bottom layer to realize anonymous transactions between accounts, and is realized through the grafting of gateway contracts. DeFi  The privacy interaction of the project. Aztec also recently launched Noir, a programming language that makes it easier and more convenient for developers to build applications with proof of zero knowledge on Ethereum.

Currently, Azetc TVL is about $11 million, according to DeFi Llama. Currently, Aztec has no immediate plans to issue a Token, but it is also believed to be associated with   Arbitrum, ZkSync and similar high value airdrops that are expected to be released. But before that. FTX  Third-party compliance tools of trading platforms such as Aztec have frozen accounts that have transferred funds from privacy agreements such as Aztec. Users should pay attention to relevant security when interacting.

This article will introduce Aztec's ecological priorities.

One of Aztec's highlights was Aztec Connect, a private rollup of Ethereum DeFi protocol and Aztec, which went live on July 7th. It supports privacy DeFi with the help of three parts: the Layer 1 DeFi protocol, the Aztec Connect SDK, and the Aztec Connect Bridge contract. Aztec Connect extends the functionality of Zk.money by adding the capabilities of the blue Chip DeFi partner, which allows private access to the protocols on the Ethereum main network through bulk transactions with other Zk.money users, making it easier for Ethereum projects to integrate Aztec. Aztec Connect is a proxy service like DeFi that allows anyone to deposit into the Aztec network, interact with Ethereum DeFi, and rely on trusted contracts and liquidity at Layer 1. The current Aztec Connect ecosystem includes mainstream Ethereum DeFi protocols, including   Aave, Curve, Lido, Compound  Liquity and others.

Zk.money

Zk.Money is the first Aztec Network application, released in March 2021. The old version of Zk.money can only implement simple transfer payments, so that the funds within it can be sent to another Aztec account or withdrawn to Layer 1  in complete privacy; , but only support   A small number of assets such as ETH, DAI and renBTC, and a trading cap of 5 ETH or 10,000 DAI at a time.

The user sends zkETH or DAI to the username (@name) on Zk.money and the recipient gets zkETH or DAI; If zkETH or DAI is sent to any Ethereum address other than Zk.money, the wallet will receive regular ETH or DAI. Zk.money officially claims to have more than 75 since its launch. 000 registered users, more than 225,000 transactions and $80 million in total transactions, while 96% cheaper than existing privacy transfer protocol fees. .

The new version of Zk.Money retains the original transfer payment function and adds the privacy DeFi function. Users' funds can be used to interact with the mainstream DeFi protocol under the condition of full privacy protection. Some examples include using ETH or DAI to borrow on AAVE, pledging ETH on LIDO to obtain rewards, depositing DAI in a vault to obtain passive income, etc. However, Zk.Money currently only supports def-earn and Trade is still in development.

ZKPay

ZKPay is a fast withdrawal bridge designed for Aztec privacy payments. Assets can take up to six hours to access on the Aztec network, but only seconds on ZKPay. After the v2.0.0 upgrade, ZKPay now supports ETH, DAI, USDT, USDC  And other mainstream asset transfers. In addition to supporting the Ethereum mainnet, ZKPay also supports   Polygon  Network transfer. Like Zk.Money, ZKPay has a transaction cap of 5 ETH or 10,000 DAI. At present, ZKPay's swap function is still under test, and the right to participate in the test is limited to VIP members. ZKPay team creates ZK badges whenever in V  1 Mint this badge with a total deposit of 0.1 ETH or with a total deposit of 0.1 ETH at V2 and at least 3 deposits. The team said that in the future, ZKPay will be discounted for users with ZK badges.

Trelis

Trelis is an unhosted Ethereum payment integration that is currently in beta. In beta mode, Trelis can be accessed using payment links, the Trelis API, and the WooCommerce Plugin. The transaction cap is 100 USDC and supports all major Ethereum wallets. Currently, TrelisTrelis supports USDC and ETH to generate Token payment links. The prominent function of Trelis is Gasless Payments, which allows the user (sender) to pay without paying gas. The merchant (receiver) buys Trelis Gas credits in advance, and Trelis pays gas on behalf of the user. However, this feature is limited to paying with USDC. Also note that if gas prices spike, USDC transactions revert to standard transactions and customers pay for gas; If the total amount of gas payable exceeds 5% of the transaction value. , Trellis will revert the Gasless deal to a standard deal. Trelis will charge 10% off this feature. gas  For service charges, Gasless pays about 1.9 times the cost of standard payments.

Nucleo

In November, Nucleo was completed by Bain Capital and 6  th Man Ventures led a $4 million seed round. Nucleo is a privacy multi-signature infrastructure for organizations to develop privacy transactions, privacy DeFi, privacy funding, etc. Public transparency is beneficial, but it also risks exposing individuals and organizations to legal, strategic and operational loopholes in many areas, which Nucleo is committed to addressing. With Nucleo, individuals, communities, and organizations can enjoy privacy while remaining audit friendly. In addition to working with Aztec, Nucleo also works with Aleo and Espresso. Nucleo has only launched sign-on functions so far. DeFi, Fundraise, and Fundraise will follow. Currently Nucleo is in the beta phase and users need to join the waiting list if they want to join the beta.

Like most privacy tracks, Aztec ecology is in the initial stage to be developed, with few original projects. Currently, it mainly integrates with mainnet DeFi protocol, and its goal is to realize privacy interaction with all mainnet protocols and smart contracts.
