Application 1: The "Provably Fair Launchpad" Tool

First and foremost, the demo and the github repo. I would truly appreciate any feedback, so don’t hold back ; )

Concept: This is a simple, yet powerful, business-to-business tool aimed at Web3 projects, marketers, and community managers. A persistent problem in the space is community distrust around giveaways, raffles, and whitelist selections for high-demand NFT mints or token sales. These processes are often opaque, leading to accusations of favoritism or insider allocation. This tool directly solves that problem by providing a verifiably fair and transparent selection mechanism, which becomes a marketable feature for any project that uses it.

Core Functionality: The application provides a clean interface for a project manager to conduct a verifiably random drawing. The manager pastes a list of participant wallet addresses, specifies the number of winners, and initiates the selection. The application then uses the dcipher VRF to generate the random selection on-chain. The results are displayed, along with a cryptographic proof that anyone can audit to confirm the fairness of the process.

The business viability of this application is strong because it provides a clear solution to a high-value problem in the Web3 space: community distrust. Its success hinges on overcoming the inertia of free, less-transparent alternatives.

Core Value Proposition

• It solves the trust problem. Most giveaways are opaque, leading to accusations of favoritism.

• Its key feature is verifiable proof. This turns a raffle from a community management chore into a marketable feature that demonstrates a project's commitment to fairness.

The project consists of two main components:

• Smart Contracts (/contracts): Solidity contracts for the launchpad functionality

• Frontend (/dcipher-launchpad-frontend): Next.js web application for user interaction

• Foundry (for smart contract development)

• Git

Smart Contract Development

1. Install Foundry

    curl -L https://foundry.paradigm.xyz | bash
    foundryup
   

2. Navigate to contracts directory

    cd contracts
   

3. Install dependencies

    forge install
   

4. Compile contracts

    forge build
   

5. Run tests

    forge test
   

6. Deploy contracts

    forge script DeployProvablyFairLaunchpad --rpc-url <RPC_URL> --private-key <PRIVATE_KEY> --broadcast
   

Frontend Development

1. Navigate to frontend directory

    cd dcipher-launchpad-frontend
   

2. Install dependencies

    npm install
   

3. Run development server

    npm run dev
   

4. Build for production

    npm run build
   

5. Start production server

    npm start
   

🧪 Testing

Smart Contract Tests

cd contracts
forge test

Frontend Tests
