AZTEC Demonstration Scripts

This directory uses the aztec-crypto-js library to issue AZTEC confidential transactions, using AZTEC contracts deployed to the following networks:

• Main-net
• Rinkeby
• Kovan
• Ropsten

In order to use these scripts, Ethereum private keys and addresses need to be added to accounts.json; these are the accounts used to issue AZTEC transactions. The demo script currently requires three but you can modify it to fit your purposes.

The demo script will, if used on the Ethereum main-net, convert 10 DAI into zero-knowledge AZTEC notes, and then issue multiple AZTEC notes to the addresses in accounts.json. If the first account in accounts.json does not have 10 DAI the transactions will throw. You can modify the amount of DAI transferred, the sizes of the AZTEC notes and their recipients in demoTransactions.js.

For the test-nets, the AZTEC token smart contract is attached to a dummy ERC20 contract that anybody can mint from - the demoTransactions.js script will automatically mint tokens for you.

You can deploy your own AZTEC contracts (attached to different ERC20 token contracts if you want) by running truffle migrate, specifying the appropriate network. See the truffle docs for more details.

If you're running this script on a local test-net, run truffle migrate to deploy the AZTEC contracts locally.

Usage

1. run git clone git@github.com:AztecProtocol/AZTEC.git
2. run git submodule update --init --recursive
3. followed by npm install && npm install ./aztec-crypto-js && npm install ./aztec-demo-js

Then, to test and deploy the contracts:

1. ./node_modules/.bin/ganache-cli && truffle migrate
2. set your private key or mnemonic in a .env file
3. run truffle tests with truffle test
4. go the demo submodule cd aztec-demo-js
5. run javascript tests with npm run test

Finally, run the demo transactions script (to the appropriate network) with the following:

npm run demo:development (to a network running on port 8545)
npm run demo:rinkeby
npm run demo:kovan
npm run demo:ropsten
npm run demo:mainnet
