Chainlink Data Feeds Demo using Brownie

Chainlink Data Feeds Implementation for Brownie

This is a simple demo using Chainlink Data Feeds, deployed with brownie.

Requirements

• Python3.x +
• eth-brownie
• ganache

Deployed using Goerli Network

Steps to reproduce

1. Clone the repo with git clone.

2. Rename the .env.example for .env and replace using your Wallet Key and Infura project id.

   Note: Do not use a wallet with real assets, use a wallet with tokens for the testnets.

3. Run de code using brownie

    brownie run scripts/deploy.py --network goerli.

For Local Testing

Chainlink Data Feeds are live contracts you must interact with, and they don't exists on a local development environment.

So we use Mocks (Fake Contracts to get them), which return a fake price, this is helpful for local testing only.

Just run the code without the network flag.

brownie run scripts/deploy.py

Remember to have ganache installed for this.
