New Challenge 4: Build a DEX

[Nadai2010]

Overview

Create a new challenge based on Speed Run Ethereum, specifically Challenge 4, but adapted to Starknet.

To access this challenge, users must have completed challenges 0, 1, 2, and 3 from Speed Run Ethereum.

⚖️ Build a DEX

💵 Develop a decentralized exchange (DEX) that allows swapping STRK for other tokens and vice versa.
💰 This is achieved by having the smart contract hold reserves of both assets and using a price function based on the reserve ratio.
🔄 Liquidity providers will receive a token representing their share of the reserves and transaction fees.

Proposed Solution

1. Understand the challenge mechanics

   • Analyze how the original Speed Run Ethereum Challenge 4 works.
   • Identify the necessary modifications to adapt it to Starknet.
   • Implement swaps between STRK and other tokens.

2. Create a separate private repository

   • Implement the challenge in Starknet using Cairo.
   • Ensure the contract logic follows best practices.
   • Document the challenge structure and steps in a README.md, following the format of previous challenges.

3. Assign repository access

   • Grant repository access to nadai2010 or 0xquantum3labs for review and feedback.

Next Steps

• Define the exact challenge specifications for the Starknet environment.
• Develop and test the smart contract implementation.
• Provide a step-by-step guide for users to complete the challenge.
• Review and iterate based on feedback.
