Yield farming concepts in Blockchain / Solidity - Mini Project: Build & Apply

Yield Farming Concepts

📖 Scenario: You want to understand how yield farming works by simulating a simple yield farming scenario in Python. Yield farming means you deposit tokens into a pool and earn rewards based on your deposit and a reward rate.

🎯 Goal: Build a small program that calculates the rewards earned by different users based on their deposits and a fixed reward rate.

📋 What You'll Learn

Create a dictionary with user names and their deposited token amounts

Create a variable for the reward rate (percentage)

Calculate the rewards for each user using a dictionary comprehension

Print the rewards dictionary showing each user and their earned rewards

💡 Why This Matters

🌍 Real World

Yield farming is a popular way in blockchain to earn passive income by depositing tokens and earning rewards. This project simulates the basic math behind it.

💼 Career

Understanding yield farming concepts and how to manipulate data structures is useful for blockchain developers and analysts working with decentralized finance (DeFi) applications.

1

Create the deposit data

Create a dictionary called deposits with these exact entries: 'Alice': 1000, 'Bob': 1500, 'Charlie': 500

Blockchain / Solidity

# Create the deposits dictionary with exact values
# Your code here

Need a hint?

Use curly braces to create a dictionary with keys as user names and values as their deposits.

2

Set the reward rate

Create a variable called reward_rate and set it to 0.05 (which means 5%)

Blockchain / Solidity

deposits = {'Alice': 1000, 'Bob': 1500, 'Charlie': 500}
# Set the reward rate to 0.05
# Your code here

Need a hint?

Just assign the number 0.05 to the variable reward_rate.

3

Calculate rewards using dictionary comprehension

Create a dictionary called rewards using dictionary comprehension that calculates each user's reward by multiplying their deposit by reward_rate. Use user and amount as the loop variables in for user, amount in deposits.items()

Blockchain / Solidity

deposits = {'Alice': 1000, 'Bob': 1500, 'Charlie': 500}
reward_rate = 0.05
# Calculate rewards dictionary using dictionary comprehension
# Your code here

Need a hint?

Use the syntax: {key: value_expression for key, value in dictionary.items()} to create the rewards dictionary.

4

Print the rewards

Write a print statement to display the rewards dictionary

Blockchain / Solidity

deposits = {'Alice': 1000, 'Bob': 1500, 'Charlie': 500}
reward_rate = 0.05
rewards = {user: amount * reward_rate for user, amount in deposits.items()}
# Print the rewards dictionary
# Your code here

Need a hint?

Use print(rewards) to show the rewards dictionary.
