ens-permissions 0.2.0

Add a short description here!

Permissions audit package

This project defines a simple library for obtaining smart contract permissions and building a graph.

It's aimed at contracts using Openzeppelin's AccessControl module.

There's a frontend for this at https://ensuro.co/ens-permissions-frontend/

Development

There's an app developed for Google Cloud Functions.

To run the function locally you will need a virtualenv with functions-framework and the app requirements:

python3 -m venv venv
. venv/bin/activate
pip install -r requirements.txt -r requirements.dev.txt
pip install -e .

Running the function locally

Requires a few environment variables. See .env.sample.

cp .env.sample .env

# Review .env vars
$EDITOR .env

# Run the function
functions_framework --debug --target=permissions_graph

Then test it with:

curl -o test.gv http://127.0.0.1:8080/?address=0x47E2aFB074487682Db5Db6c7e41B43f913026544

dot -Tsvg test.gv > test.svg

Deployment

Edit config/environment.yml with your config and then deploy with gcloud:

gcloud functions deploy permissions_graph \
    --env-vars-file config/environment.yml \
    --runtime python39 --trigger-http --allow-unauthenticated

TODO

• Deploy app from github actions
• Split ens_permissions into its own pypi library
• Add support for Ownable contracts
• Address book
• Add multisig intelligence (detect when a role member is a multisig and obtain its members)
• Timelock detection
