    Migrate the 0x system of smart contracts on the network of your choice using these migrations.


    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


    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


    yarn clean


    yarn lint


    V2 smart contracts

    In order to migrate the V2 0x smart contracts to TestRPC/Ganache running at http://localhost:8545, run:

    yarn migrate:v2


    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


    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.
