Aztec.nr

Aztec.nr is the smart contract development framework for Aztec. It is a set of utilities that help you write Noir programs to deploy on the Aztec network.

Contract Development

Prerequisites

• Install Aztec Sandbox and tooling
• Install the Noir LSP for your editor.

Flow

1. Write your contract and specify your contract dependencies. Every contract written for Aztec will have aztec-nr as a dependency. Add it to your Nargo.toml with

# Nargo.toml
[dependencies]
aztec = { git="https://github.com/AztecProtocol/aztec-packages/", tag="aztec-packages-v0.71.0", directory="noir-projects/aztec-nr/aztec" }

2. Write your contracts.
3. Profile the private functions in your contract to get a sense of how long generating client side proofs will take
4. Write unit tests using the TXE and end-to-end tests with typescript
5. Compile your contract
6. Deploy your contract

📄️ Profiling Transactions

An Aztec transaction typically consists of a private and a public part. The private part is where the user executes contract logic within the PXE and generates a proof of execution, which is then sent to the sequencer.

📄️ Testing Contracts

Aztec contracts can be tested in a variety of ways depending on the needs of a particular application and the complexity of the interactions they must support.

📄️ How to Compile a Contract

Once you have written a contract in Aztec.nr, you will need to compile it into an artifact in order to use it.

📄️ How to Deploy a Contract

Once you have compiled your contracts you can proceed to deploying them using aztec.js which is a Typescript client to interact with the sandbox.
