zkPassport on Aztec Sandbox

Aztec Sandbox License: Apache-2.0 Tests

A prototype for private token transfers on Aztec Network featuring integrated compliance mechanisms like per transaction send limits, transaction send limits over a given time period (e.g. monthly), and country whitelisting.

Usage

Install dependencies

npm install

Ensure Aztec Sandbox version 0.16.9 is running

In a separate terminal:

cd ~/.aztec && DEBUG=aztec:simulator:oracle SANDBOX_VERSION=0.16.9 docker compose up

Run tests

Compile contracts and run integration tests:

npm run test

Run integration tests without (re)compiling contracts:

SKIP_COMPILE=1 npm run test

Compile contracts

npm run compile

Clear cache

The cache contains compiled contract artifacts, deployed contract addresses, and the Slow Update Tree database.

If you are encountering issues you may need to clear the cache.

npm run clear_cache
