This GitHub Action allows you to automate smart contract deployments across multiple networks using BuildBear’s infrastructure. With a setup, you can deploy contracts on the specified networks, making it easier to manage multi-network deployments in your CI/CD pipeline.

• Deploys smart contracts on specified networks.
• Integrates seamlessly with the BuildBear platform.
• Supports custom deployment commands and network specifications.

The network input is expected as a JSON array containing network details, each with chainId and optionally a blockNumber:

[
  {
    "chainId": 1,
    "blockNumber": 12000000 // Optional
  },
  {
    "chainId": 10
  }
]

During the execution of this action, the following environment variables are available:

• BUILDBEAR_RPC_URL: The RPC URL provided by BuildBear, enabling connections to the sandbox.
• MNEMONIC: A 12- or 24-word mnemonic phrase used for signing transactions during deployment.

In your GitHub workflow file, you can set up this action as follows:

name: deploy to BuildBear Sandbox

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repository
        uses: actions/checkout@v4
        with:
          submodules: recursive

      - name: Install Foundry
        uses: foundry-rs/foundry-toolchain@v1
        with:
          version: nightly

      - name: Show Forge version
        run: forge --version

      - name: Run BB Action CI
        uses: BuildBearLabs/[email protected]
        with:
          network: |
            [
              {
                "chainId": 1,
                "blockNumber": 12000000 // Optional block number
              },
              {
                "chainId": 10
              }
            ]
          deploy-command: "make deploy"
          buildbear-token: "${{ secrets.BUILDBEAR_TOKEN }}"

Note: Ensure that the buildbear-token is securely stored as a secret in your GitHub repository under BUILDBEAR_TOKEN.

1. Set up GitHub Secrets: Add your BuildBear API token as a secret in your repository settings.
2. Define Networks: In the network input, specify the networks and optional block numbers for deployment.
3. Add Deployment Command: Define the deployment command under deploy-command.
4. Run Workflow: Trigger the workflow on push or any specified event to deploy contracts on the selected networks.

• Ensure the deploy-command matches the command in your project for deploying contracts.
• This action requires Node.js 20 (node20) to run the main deployment script.
