Chainlink Mix

Chainlink Mix is a public starter repository for developing and working with Chainlink-enabled Ethereum smart contracts using Solidity, Python and the eth-brownie toolkit. It includes scripts and examples for local chains and Sepolia, with README sections covering Price Feeds, VRF, API calls and Automation.

Practical overview

When it fits

Use it to study or adapt its Brownie-based Chainlink examples, particularly for local development. Consider the repository’s maintenance warning before choosing it as the basis for new work.

Who it is for

  • Ethereum developers seeking Brownie-based Chainlink contract examples.
  • Learners exploring local smart-contract workflows or Sepolia testnet deployment.

Documented uses

  • Start a Python project for working with Chainlink smart contracts.
  • Explore contract workflows involving Price Feeds, VRF, API calls and Automation.
  • Deploy and test contracts on a local Ganache chain or Sepolia, following the repository instructions.
Before you choose

Requirements & limits

  • The documented stack includes Solidity, Python, eth-brownie, Node.js/npm and, for local testing, Ganache.
  • The README sets Sepolia as the default testnet and describes Infura project credentials, a wallet private key, and testnet ETH and LINK for testnet deployment.
  • The project warns that Brownie is no longer maintained by its creators and that the repository is not actively maintained.
  • The README recommends Chainlink Hardhat or Foundry starter kits for most use cases, but does not provide a direct migration path from this code.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up the Chainlink Mix project

Create a project from the mix and install its Python dependencies.

Before you start

  • Node.js and npm
  • Python
  • eth-brownie

Steps

  1. Install eth-brownie using the README’s pipx or pip instructions.

  2. Run brownie bake chainlink-mix.

  3. Enter the new project directory with cd chainlink-mix.

  4. Install dependencies with the command below.

    Documented command
    pip install -r requirements.txt

Expected outcome

A Chainlink project based on the repository template, with its listed Python dependencies installed.

Guide limitations

  • The repository uses eth-brownie, which its README says is no longer maintained by its creators; the repository is not actively maintained either.
