OD App

Frontend application for Open Dollar

Deployments

https://app.opendollar.com/ Production main branch

https://app.dev.opendollar.com/ Testnet dev branch

⚡️ Run the app locally

For security and resiliency we publish the app as a self-contained Docker image

1. Install Docker
2. Get the latest Release, eg. 1.7.0
3. Run the start command, replacing <VERSION_NUMBER> with the release

docker run -p 3000:3000 ghcr.io/open-dollar/od-app:<VERSION_NUMBER>
# For example:
docker run -p 3000:3000 ghcr.io/open-dollar/od-app:1.7.0

The application will be available on http://localhost:3000

For network Arbitrum Sepolia, use a release candidate (eg. 1.2.0-rc.abc123) version from the container registry

Development

Setup

Install dependencies

yarn

Setup the environment by creating the file .env.development.local:

cp example.env .env.development.local

Start the app

yarn start

If you have issues, check you are using node v16

Configuring the environment

To have the app default to a different network when a wallet is not connected:

1. Create a file and name it .env.development.local
2. Change REACT_APP_NETWORK_ID to "420"
3. Change REACT_APP_NETWORK_URL to e.g. "https://opt-goerli.g.alchemy.com/v2/{YOUR_INFURA_KEY}"
4. Change REACT_APP_FALLBACK_SUBGRAPH_URL to actual values in the format https://${GRAPH_NODE_PLAYGROUND_BASE_URL}/subgraphs/name/NAME_OF_YOUR_SUBGRAPH The current value of the GRAPH_NODE_PLAYGROUND_BASE_URL in the Render-deployed subgraph can be found in the Render dashboard under the Environment section of the NGINX Render service. The subgraph name can be queried in the Render database service by following the README.md instructions in the od-subgraph repo.

Subgraph Redundancy

When a request fails to our hosted subgraph in The Graph, we will automatically retry the request to our Render-hosted subgraph in the querySubgraph SDK function. Make sure you've set REACT_APP_FALLBACK_SUBGRAPH_URL as a .env variable to ensure there's a fallback subgraph to query.

Testing
