Concordia Contracts

In this package live the contracts that power Concordia.

This document provides information about how to build and migrate the contracts.

Prerequisites

To migrate the contracts, the targeted blockchain must be up and running. Furthermore, if uploading to a contracts provider, the provider must be available.

Compiling

To compile the contracts execute the compile script:

yarn compile

Linting

To lint the contracts execute the lint script:

yarn lint

Testing

Default host and port values of the blockchain used for testing are:

host	port
127.0.0.1	8546

Test using the default network:

yarn test

Using different host and port values for testing blockchain

Define the host and port of the blockchain using environment variables (see below). Test using the env network:

yarn test --network env

Migrating

Default host and port values of the blockchain are:

host	port
127.0.0.1	8545

Migrate (using the development network by default):

yarn migrate

Setting different host and port values

Define the host and port of the blockchain using environment variables (see below). Migrate using the env network:

yarn _migrate --network env

Notice the underscore _ prefix in the script name. This is not a mistake.

Uploading

Default hash and tag values used during contracts upload:

hash	tag
<npm_package_version>-dev	latest

To upload the contracts to a contracts provider instance execute the upload script:

yarn upload

Setting different hash and tag values

Pass the hash and tag of the contracts during script call:

yarn _upload <hash> <tag>
