Pattini is a GitHub Action designed to incentivize and reward contributors of a GitHub project. When an issue is merged by a maintainer, the pull request author automatically receives a certain amount of ERC-20 (USDC, DAI, ...).

npm install

npm test

npm run bundle

When you create a branch from the issue, add your wallet address at the end of the name of the branch with a hyphen (-).

-0x8CCbFaAe6BC02a73BBe8d6d8017cC8313E4C90A7

Your branch name should look like this example:

15-Add-blog-page-to-website-0x8CCbFaAe6BC02a73BBe8d6d8017cC8313E4C90A7

The payment will be triggered when the branch is merged to main.

Mandatory format:

<ISSUE_NUMBER>-<ISSUE_NAME>-<CONTRIBUTOR_WALLET_ADDRESS>

The repository maintainer should make sure that at least 1 review is required to allow merging.

Before merging, he should also verify if another no one else made a pull request before.

To get Pattini up and running in your repository:

1. Use this directory Pattini Contracts to retrieve the code for the contract to be deployed

2. Deploy the contract manually (in Hardhat: pnpm deploy:sepolia)

3. Once the contract has been deployed, copy the content of the Pattini.json file located in deployments/sepolia. In the directory where you want to add Pattini, create the folder .github/workflows, create the file pattini.config.json and paste the content you copied earlier.

4. In the same folder (.github/workflows), create the pattini.yml file and paste the following code:

name: Run Pattini

on:
  pull_request:
    types:
      - closed
  push:
    branches:
      - '*' 

jobs:
  branch-creation-check:
    runs-on: ubuntu-latest
    if: github.event_name == 'push' && github.event.created
    steps:
      - name: Extract Issue Number
        run: echo "ISSUE_NUMBER=$(echo ${{ github.ref }} | awk -F/ '{print $3}')" >> $GITHUB_ENV
      - name: Pattini app
        uses: w3hc/pattini@vTest
        with:
          PRIVATE_KEY: ${{ secrets.WALLET_OWNER_PRIVATE_KEY }}
          ACTION: ${{ github.event_name }}
          ISSUE_NUMBER: ${{ env.ISSUE_NUMBER }}
          REPOSITORY: ${{ github.repository }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  on-merge-pull-request:
    runs-on: ubuntu-latest
    if: github.event_name == 'pull_request' && github.event.action == 'closed' && github.event.pull_request.merged
    steps:
      - name: Extract Merged Branch Name
        id: extract-merged-branch
        run: echo "ISSUE_NUMBER=${{ github.event.pull_request.head.ref }}" >> $GITHUB_ENV

      - name: Pattini app
        uses: w3hc/pattini@vTest
        with:
          PRIVATE_KEY: ${{ secrets.WALLET_OWNER_PRIVATE_KEY }}
          ACTION: ${{ github.event_name }}
          ISSUE_NUMBER: ${{ env.ISSUE_NUMBER }}
          PULL_REQUEST_NUMBER: ${{ github.event.pull_request.number }}
          REPOSITORY: ${{ github.repository }}

5. Create a secret variable in the GitHub parameters of your repository. This must be called WALLET_OWNER_PRIVATE_KEY and stores your wallet's private key, which will be used to pay the fees for the contract to interact with the blockchain.

6. Once all these steps have been completed, the actions will be automatically executed each time a new branch is created and each time a branch is merged.
