Important Prerequisites

To get the most out of this bootcamp, we recommend preparing the following environment before you start. Some items will be briefly covered in class so we can spend more time on hands-on work.

Required

• Node.js v20 or later - Download here
• Bun v1.3 or later - Download here
• CRE CLI - Installation guide
• CRE account - Sign up at cre.chain.link and complete cre login (see CRE CLI Quick Setup)
• Deployment access - Fill in this form with your own information to get deployment access
• Git - Download here

Optional (only needed for the onchain write exercise)

• Add the Ethereum Sepolia network to your wallet - Add it here
• Get Sepolia ETH from a faucet - Chainlink Faucet

Note: Both case studies serve deterministic API data from a local mock server, so you can complete every demo without a real LLM API key.

The two case studies used in this bootcamp come from the official CRE templates repo. We will clone and walk through them together in class:

git clone https://github.com/smartcontractkit/cre-templates.git

The two case studies live at:

Note: You don’t need to read the code ahead of time! We will walk through the key parts line by line during the bootcamp. Just clone the repo in advance.
