aztec-sandbox

Aztec Sandbox is a package that allows for a simple development environment on Aztec stack. It creates an Private eXecution Environment (PXE) that listens for HTTP requests on localhost:8080 by default. When started, it deploys all necessary L1 Aztec contracts and then starts listening for RPC requests.

How to run:

Docker Compose

The easiesty way to run is by using docker compose up. This will create two containers:

1. The sandbox listening on port 8080
2. An anvil instance listening on port 8545

Node Server

You can also run it as a standalone node server with:

yarn start

It will look for a local Ethereum RPC to talk to but you can change this with the ETHEREUM_HOST environment variable.

You'll also need to run ./bootstrap.sh in the circuits/cpp directory in order to build the WASM binaries.

Examples

The package also includes 2 examples. There are some system prerequisites that you will need to run these locally:

• nvm
  • Node version > 18
• yarn
• jq

Before running locally you'll need to:

• Head to l1-contracts directory and run ./bootstrap.sh
• Then go to `yarn-project and run:
  • yarn install
  • yarn build And you should be good to go!

From the aztec-sandbox directory, you can run the two existing examples:

• Deployment, mint and transfer on an Aztec Private Token
  • yarn run:example:token
• An L1 / L2 uniswap token trade.
  • yarn run:example:uniswap
  • To run this example, you need to set the following vars:

export FORK_BLOCK_NUMBER=17514288
export FORK_URL=<YOUR_RPC_URL e.g. https://mainnet.infura.io/v3/API_KEY>

Publishing

This package is set-up to be published on dockerhub by CI whenever there's a tagged release on master branch. It's published under the tags aztecprotocol/aztec-sandbox:latest & aztecprotocol/aztec-sandbox:<version-tag>.
