Requirements

You will need a MacOS or Linux system.

• Install the latest version of parity.
• Install the latest version of solc.
• Install the latest version of npm.

Local development is worked against TestRPC (which will be installed via npm). Parity is used to test against a local dev-chain (see parity-spec.json) and can also be used to test agains Ropsten TestNet or the Public MainNet.

Getting Started

Production Environment

• Explorer URL: https://explorer.metronome.io
• Auction Board URL: https://metronome.io

Production Contracts

Version: autonomoussoftware/metronome#35a6cd3

Ethereum Contract addresses

Ethereum Classic Contracts

Development environment

Installation

• npm install to install all module dependencies
• npm test to compile all the contracts and run the entire test suite agains TestRPC
• TESTFILE=test/<testfile>.js npm run testrpc:single to compile and run a single test file

Parity Local Dev Chain Testing

• ./deploy to compile all the contracts and deploy them to a local parity dev-chain (this script will automatically start Parity)
• geth attach --preload js/metronome.js,js/const.js,js/initMetronome.js to open a geth console and start metronome
• geth attach --preload js/metronome.js,js/const.js,js/initPostAuction.js to open a geth console and start metronme (bypassing the initial auction)

Here geth console commands to emulate auction transactions

• loadScript('js/testStart.js') to load a geth test script for auction buys
• call pingBuy() to simulate a buy (this will also initiate a buy every 30 seconds)

Test Suite

Sample code of how to interact with the smart contracts can be viewed in the Truffle tests.

Unit Tests (./test)

• shared folder contains utility code shared amongs multiple test cases
• auctions.js tests for the Auction contract
• deployment.js tests for emulating actual deployment process for all the contracts
• erc-compliance.js tests for ERC20 and ERC827 compliance
• fixedMath.js tests for the Fixed Math contract (internal functions used by Metronome)
• formula.js tests for the Formula contract (math for minting calculations)
• metronome.js tests for Metronome use cases involving the AutonomousConverter
• mtnToken.js tests for MET Token use cases (i.e., transfering tokens)
• owned.js tests for Ownership operations (i.e., changeOwnership)
• pricer.js tests for Pricer contract (internal functions used by Metronome)
• proceeds.js tests for Proceeds contract to manage ETH funds
• smartToken.js tests for internal SmartToken contract used by AutonomousConverter
• tokenLocker.js tests used for time locking founder tokens
• tokenPorter.js tests for exporting MET tokens to be imported to another chain

Timed Tests (./timed-tests)

Simuating time proved to be a challenge, so we had to migrate a seperate suite of tests so that we can take advantage of evm_increaseTime. This allowed us to better test targeted scenarios that depended on system time.

• ac.js timed tests for AutonomousConverter
• auctions.js timed tests for Auctions
• proceeds.js timed tests for Proceeds
• subscriptions.js timed tests for MET Token subscriptions
• tokenLocker.js timed tests for TokenLocker withdraws
