Move FWD 2025

Challenge 1: Simple TODO List (Easy) 

Problem Statement 

Create a personal TODO list where users can add tasks, mark them as complete, and delete them. Each user owns their own TODO list object. 

Requirements 

• Create a TODO list object for each user 
• Add tasks with title and description 
• Mark tasks as complete/incomplete 
• Delete tasks 
• Each task has a unique ID within the list 

Key Concepts to Implement 

• Owned objects 
• Vector manipulation 
• Struct definitions 
• Object transfers 

Starter Code Structure 

Expected Output 

• User creates their own TODO list 
• Can add multiple tasks 
• Can mark tasks complete 
• Can delete tasks 

Test Cases to Implement 

1. Create list and add task 
2. Complete a task 
3. Delete a task 
4. Add multiple tasks and verify count 

Challenge 2: Digital Guestbook (Easy) Problem Statement

Build a shared guestbook where anyone can leave a message. Messages are stored on-chain and cannot be edited or deleted once posted. 

Requirements 

• Create a shared guestbook object 
• Users can post messages with their name and message content ● Each message includes timestamp 
• Messages are immutable once posted 
• Display all messages 

Key Concepts to Implement 

• Shared objects 
• Vector of structs 
• Timestamp handling 
• Public entry functions 

Starter Code Structure 

Expected Output 

• Anyone can post messages to the shared guestbook 
• Messages include name, content, and timestamp 
• All messages are visible and immutable 

Test Cases to Implement 

1. Post a message 
2. Post multiple messages from different users 
3. Read messages back 
4. Verify message count 

Submission Guidelines 

What to Submit 

1. Complete Move module implementation for your chosen challenge(s) 2. Move.toml file with dependencies: 

toml 

None 

[package] 

name = "your_challenge_name" 

version = "0.0.1" 

[dependencies] 

Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/testnet" } 

[addresses] 

your_module = "0x0" 

1. Basic tests showing your module works 
2. README.md explaining how to build and test 

How to Test Locally 

bash

Shell 

# Build your module 

sui move build 

# Run tests 

sui move test 

# Publish to testnet (optional) 

sui client publish --gas-budget 100000000 

Evaluation Criteria 

• Completeness : All required functions implemented 
• Correctness : Code compiles and works as expected 
• Code Quality : Clean, readable code with comments with atleast 4 commits.
• Submissions: Code should be deployed to testnet and should share the package ID with valid test results 

○ Need to share the published packaged id in discord 

(https://discord.com/invite/sQEkBSZbd7) 

Tips 

• Start with the struct definitions 
• Implement one function at a time 
• Use sui move test frequently to check your work 
• Add assert! statements for validation 
• Check the Sui examples repo for reference
