Aztec State Channels

Installation

1. Ensure correct versioning of aztec-nargo CLI:

aztec-nargo -V
// nargo version = 0.23.0
// noirc version = 0.23.0+602f23f4fb698cf6e37071936a2a46593a998d08
// (git version hash: ea6aebcc4e190d9dbadaf1dd0f70950651eed615,, is dirty: false)

You can run VERSION=0.21.0 aztec-up to ensure you have a valid aztec-nargo compiler cli

2. Set up the proper folder structure for the imports as they currently exist

// Once everything is installed, you should have:
PARENT_DIR/
  | - aztec-packages
  | - aztec-state-channels
// such that npm imports in statechannel can access the local aztec-packages build with `file:../aztec-packages/yarn-project/*`

3. Install the fork of aztec-packages that has compatible @aztec/* for statechannel repo and runs a modified PXE through the sandbox that supports the state channel construction

a. clone the repo in your parent dir: git clone https://github.com/mach-34/aztec-packages && cd aztec-packages

b. ensure you are on the right branch: git checkout app_circuit_pxe

c. build the entire aztec-packages stack locally: ./bootstrap.sh

• This can take over an hour. If you have a compatible version of aztec-packages already built locally, you can skip 99% of build time by only building yarn_project: cd yarn_project && bootstrap.sh
• You may experience issues building barretenberg. Visit the official aztec-packages/barretenberg README.md for some help with this

4. Install the Aztec State Channels repository in a new terminal window

a. in PARENT_DIR, run git clone https://github.com/mach-34/aztec-state-channels && cd statechannel

b. ensuring file:../aztec-packages/yarn-project/* will work for package.json, run npm i (yarn will not work)

Running Tests

1. Start Services

a. In a new terminal in the aztec-state-channels folder, run a local Ethereum dev node with npm run anvil

b. In a new terminal in the aztec-state-channels folder, run the sandbox (and first PXE) with npm run sandbox

c. In a new terminal in the aztec-state-channels folder, run a second PXE with npm run pxe:secondary

2. Run the aztec-state-channel unit tests

• To run only the state channel tests, run npm run test:statechannel

• To run only the contract logic unit tests, run npm run test:logic

• To run all test suites, run the normal npm run test
