Brownie Github Actions workflow

Question

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?

Answer 1

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
