Agoric Platform SDK
This repository contains most of the packages that make up the upper layers of the Agoric platform, with the endo repository providing the lower layers. If you want to build on top of this platform, you don't need these repositories: instead you should follow our instructions for getting started with the Agoric SDK.
But if you are improving the platform itself, these are the repositories to use.
- Node.js LTS (version 14.15.0 or higher)
- we generally support the latest LTS release: use nvm to keep your local system up-to-date
- Yarn (
npm install -g yarn)
Any version of Yarn will do: the
.yarnrc file should ensure that all
commands use the specific checked-in version of Yarn (stored in
.yarn/releases/), which we can update later with PRs in conjunction with
any necessary compatibility fixes to our
Building on Apple Silicon and Newer Architectures
Some dependencies may not be prebuilt for Apple Silicon and other newer architectures, so it may be necessary to build these dependencies from source and install that package’s native dependencies with your package manager (e.g. Homebrew).
Currently these dependencies are:
Additionally, if your package manager utilizes a non-standard include path, you may also need to export the following environment variable before running the commands in the Build section.
Finally, you will need the native build toolchain installed to build these items from source.
From a new checkout of this repository, run:
yarn install is done, the top-level
node_modules/ will contain
all the shared dependencies, and each subproject's
contain only the dependencies that are unique to that subproject (e.g. when
the version installed at the top level does not meet the subproject's
constraints). Our goal is to remove all the unique-to-a-subproject deps.
When one subproject depends upon another,
node_modules/ will contain a
symlink to the subproject (e.g.
ERTP depends upon
node_modules/@agoric/marshal is a symlink to
yarn workspaces info to get a report on which subprojects (aka
"workspaces") depend upon which others. The
section tells us when symlinks could not be used (generally because e.g.
packages/marshal/package.json says it's
0.2.0). We want to get rid of all mismatched dependencies.
yarn build step generates kernel bundles.
To run all unit tests (in all packages):
yarn test(from the top-level)
To run the unit tests of just a single package (e.g.

zoe creates the "contract facet bundle", a single file
that rolls up all the Zoe contract vat sources. This bundle file is needed by all zoe contracts before they can invoke
zoe~.install(...). If you don't run
yarn build, then changes to the Zoe contract facet will be ignored.
- All work should happen on branches. Single-commit branches can land on
trunk without a separate merge, but multi-commit branches should have a
separate merge commit. The merge commit subject should mention which
packages were modified (e.g.
(SwingSet,cosmic-swingset) merge 123-fix-persistence)
- Keep the history tidy. Avoid overlapping branches. Rebase when necessary.
- All work should have an Issue. All branches names should include the issue
number as a prefix (e.g.
123-description). Use "Labels" on the Issues to mark which packages are affected.
- Add user-visible changes to a new file in the
changelogs/directory, named after the Issue number. See the README in those directories for instructions.
- Unless the issue spans multiple packages, each branch should only modify a single package.
- Releases should be made as according to MAINTAINERS.md.
Adding a new package
To create a new (empty) package (e.g. spinning Zoe out from ERTP):
- add your sources/tests/etc to
- populate a new
packages/zoe/package.json, using other packages as a template
- edit the top-level
yarn install, and commit the resulting changes to
- check the output of
yarn workspaces infoto make sure there are no
mismatchedWorkspaceDependencies, adjust the new package's dependencies until they are correctly satisfied by the other local packages
.github/workflows/test-all-packages.ymlto add a clause that tests the new package
- commit everything to a new branch, push, check the GitHub
Actionstab to make sure CI tested everything properly
- merge with a PR
