Empathize phase

Problem Statement: Alice needs to check the price of tokens on Uniswap programmatically, as she wants real-time data for her application. She realizes that this will require specific tools and an understanding of blockchain interaction basics.

Guiding Questions for Students:

• Why would someone want to access blockchain data programmatically instead of through an app interface?
• What challenges could arise when retrieving blockchain data compared to data from traditional databases?
• How can Alice ensure that her method is both efficient and accurate?

Define phase

• Discussion: Students discuss various tools and methods for accessing blockchain data programmatically, with a focus on reading token prices.
• Introduction to Tools:
  • Web3.js and Ethers.js: Overview of these libraries for blockchain interaction, focusing on their primary features and differences.
  • Ethereum Virtual Machine (EVM): Briefly discuss how EVM executes smart contracts and allows users to retrieve specific data from contracts.
• Identify Steps:
  • Students outline the high-level steps needed for data retrieval, such as connecting to an Ethereum node, locating the Uniswap contract address, and using the ABI (Application Binary Interface) for interaction.
