[Campaign Category] Category Questions

What is useful about your DApp within one of the specified industry or enterprise verticals?

In the DeFi sector, this dApp serves as a privacy-focused launchpad that enables projects to raise capital securely and efficiently. It allows investors to participate in token sales while keeping their contributions and allocations confidential, ensuring privacy without sacrificing transparency. Projects can manage funding, vesting, claims, and refunds in a fully verifiable way, reducing risks and enhancing trust.

What exactly will you build? List the Compact contract(s) and key functions/proofs, the demo UI flow, Lace (Midnight) wallet integration, and your basic test plan.

I will build a Compliant and Privacy-Centered Crypto Launchpad (Using Midnight Compact ZK Smart Contracts).

It enables project teams to securely run public or private token sales - while keeping sensitive investor's data private and verifiable through zero-knowledge proofs.

Core Circuits

• createSale

Allows project owners to create new token sales. Supported sale types include:

• Fixed price sale
• Batch sales
• Whitelist-only sales

This circuit sets up sale configurations, pricing, limits, and access rules.

• fundSale

Enables investors to fund a sale.

This circuit updates the investor’s private state,

including:

• Contribution amount
• Total allocation

All data stays private while remaining verifiable on-chain via private state hashes.

• claimTokens

Allows investors to claim purchased tokens after the sale has ended and any vesting period has elapsed.

• refund

Enables partial or full refunds when a user qualifies.

The circuit:

• Updates contribution amounts
• Adjust total allocations
• Regenrates and uodates private state hash on-chain
• receiveFundsRaised

Allows sale organizers to withdraw raised funds into their delegated wallet coin public key.

• createYourToken

A utility circuit for users to create new tokens by specifying:

• Token amount
• Domain separation

This facilitates teams launching their custom tokens directly within the system.

• generatePrivateStateHash (Helper)

Generates the hash of a user’s private state.

This hash is stored on-chain to guarantee:

• Privacy
• Data integrity
• Verifiable correctness
• receiveFund (Helper)

Processes incoming investor funds and updates:

• QualifiedCoinInfo
• Sale TVL (Total Value Locked)
• removeAdmin

Allows the super admin to remove an admin account using ZK logic to ensure correctness and authorization.

Private Data (Stored Privately, Verified Publicly)

Each investor’s private state includes:

• Contribution amount
• Total claim
• Already claimed amount
• Sale ID

A hash of this private state is stored on-chain to ensure data correctness without exposing sensitive details.

Witnesses

The following witnesses support the contract logic:

• local_secret_key: retrieves the user’s private key
• generate_sale_id: creates a random sale ID
• get_current_time: fetches current time in ms
• calculateTotalAllocation: computes allocation for fixed or dynamic pricing
• update_user_private_state: writes new private data
• get_user_private_state_hash: retrieves private state hash
• remove_sale_from_private_state: clears or resets user private state when needed
• calculate_vest_claim_percentage_per_day: calculates the percentage of user's vested claim per day
• calculate_total_vest_claim: calculate the total amount of user vested claim

These witnesses enable secure ZK operations while maintaining full privacy.

UI Flow

The user interface will offer a clean, guided experience with the following steps:

• Connect Wallet
• Protocol Dashboard (overview of sales, history, metrics)
• Admin Dashboard (sale creation, management)
• Proposal Submission Dashboard (for new project listings)
• Projects Dashboard (active, upcoming, and past projects)
• Fund Project Button (invest in a sale)
• Claim Project Button (claim tokens post-sale/vesting)

How will other developers learn from and reuse your repo? Describe repo structure, README contents, docs/tutorials, test instructions, and extension points. Which developer personas benefit, and how will you gauge impact (forks, stars, issues, remixes)?

This project is designed not only as a functional decentralized launchpad but also as a reference implementation that developers can learn from and build upon. To support this, we provide several developer-focused resources:

Comprehensive Documentation

We have created detailed documentation in the project’s README.md file, which explains:

• How the dApp works end-to-end
• How to run the project locally
• How the smart contracts, circuits, and UI integrate
• How Compact (Midnight’s privacy-preserving contract language) is used in practice

This allows developers to quickly understand and replicate the setup in their own projects.

Fully Open-Source Codebase

The entire repository is open-source, providing full access to:

• All Compact smart contract code
• All circuits used for private state management
• Wallet connection patterns
• Contract deployment scripts
• UI components and integration logic

By exploring the code, developers can learn:

• How to write data-protecting Compact smart contracts
• How to manage private states and generate ZK proofs
• How to implement privacy-centric workflows on Midnight
• How to integrate contracts with a frontend using ready-made tools and packages

This significantly reduces the learning curve for building on Midnight.

Real-World, Practical Examples

The project showcases real use cases involving:

• Complex contract interactions
• Zero-knowledge private state hashing
• Token creation
• Sale logic (fixed, dynamic, whitelist, batch)
• Fund handling and vesting
• These examples serve as templates that developers can modify for their own applications.

Video Tutorial for Developer Clarity

We will provide a video walkthrough explaining:

• The overall architecture
• How the circuits work
• How the private state logic is implemented
• How to run and modify the code

This visual guide helps developers understand the project faster and with less friction.
