Brownie Github Actions workflow


I am trying to deploy smart contracts on Ethereum Sepolia testnet using python brownie eth-brownie==1.19.3. My scripts work locally, but I want to deploy from Github Actions directly for a CICD pipeline for smart contracts.

Does anyone have a workflow.yaml for brownie?


Solution

  • The workflow.yaml below works for me. To implement this add the following variables to your repo in Settings > Secrets and variables > Actions:

    RPC HTTP URL FOR BLOCKCHAIN CONNECTIVITY:

    RPC_URL=REDACTED

    EXLORER URL API KEY FOR CONTRACT VERIFICATION:

    ETHERSCAN_TOKEN=REDACTED

    HOT WALLET PRIVATE KEY DEPLOYING THE CONTRACT

    PRIVATE_KEY=REDACTED

    NODE ADDRESS WHICH SERVES THE ORACLE REQUESTS TO THE CONTRACT

    NODE_ADDRESS=REDACTED

    WALLET ADDRESS TO OWN THE CONTRACT AFTER DEPLOYMENT & FULFILLMENT

    OWNER_ADDRESS=REDACTED

    The workflow.yaml is default set to Ethereum Sepolia, if deploying to another network, be sure to configure L25 (brownie netowks add YOUR_NETWORK...) in .github/workflows/workflow.yaml
