Migrations
Migrate the 0x system of smart contracts on the network of your choice using these migrations.
Contributing
We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
Please read our contribution guidelines before getting started.
Install dependencies
If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
yarn config set workspaces-experimental true
Then install dependencies
yarn install
Build
To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
PKG=@0x/migrations yarn build
Or continuously rebuild on change:
PKG=@0x/migrations yarn watch
Clean
yarn clean
Lint
yarn lint
Migrate
V2 smart contracts
In order to migrate the V2 0x smart contracts to TestRPC/Ganache running at http://localhost:8545, run:
yarn migrate:v2
Publish
0x Ganache Snapshot
The 0x Ganache snapshot can be generated and published in this package. In order to build the snapshot for this version of migrations run:
yarn build:snapshot
This will run the migrations in Ganache and output a zip file to be uploaded to the s3 bucket. For example, after running this command you will have created 0x_ganache_snapshot-2.2.2.zip. To publish the zip file to the s3 bucket run:
yarn publish:snapshot
This snapshot will now be publicly available at http://ganache-snapshots.0x.org.s3.amazonaws.com/0x_ganache_snapshot-latest.zip and also versioned with the package.json version.
0x Ganache Docker Image
We also publish a simple docker image which downloads the latest snapshot, extracts and runs Ganache. This is not required to be built when migrations change as it always downloads and runs the latest zip file. If you have made changes to the Dockerfile then a publish of the image is required. To do this run:
yarn build:snapshot:docker
yarn publish:snapshot:docker
The result is a published docker image to the 0xorg docker registry. To start the docker image run:
docker run -p 8545:8545 -ti 0xorg/ganache-cli:latest
This will pull the latest zip in the s3 bucket, extract and start Ganache with the snapshot.
In the event you need a specific version of the published Ganache snapshot run the following specifying the VERSION environment variable:
docker run -e VERSION=2.2.2 -p 8545:8545 -ti 0xorg/ganache-cli:latest
Production
If deploying contract changes to mainnet, @0x/contract-artifacts should also be updated and published. The artifacts must be copied from each contracts/{package-name}/generated-artifacts/{contract}.json.
