pod Scaffold DApp

Orchestrate complete decentralized application scaffolding for pod network, from smart contracts to web frontends.

Overview

This skill guides developers through creating production-ready pod network DApps with all necessary layers:

• Smart contracts (Solidity + FastTypes)
• CLI tools (Rust + pod SDK)
• Web frontend (React + Vite + viem)
• Testing infrastructure (Foundry + Vitest)
• Deployment configuration

Use the pod-templating MCP server for backend scaffolding and built-in frontend templates for complete DApp creation.

When to Use This Skill

Trigger this skill when developers need:

Full-stack DApp creation:

• "Create a complete token DApp with frontend"
• "Build an NFT marketplace on pod network"
• "I need a voting platform with web UI"
• "Scaffold a complete DApp for pod network"

Adding frontend to existing contracts:

• "Add a web frontend to my pod contract"
• "Create a React UI for my deployed token"
• "I need a user interface for my NFT contract"

Full project setup:

• "Set up a new pod network project with everything"
• "Initialize a DApp with contract, CLI, and frontend"
• "Start a full-stack pod application"

Scaffolding Workflow

Step 1: Choose DApp Template

First, identify the appropriate full project template from pod-templating MCP server.

Available full project templates (Solidity + Rust CLI + Foundry):

For simple/custom contracts, use simple templates and add structure manually:

Recommendation: Start with full project templates (token-contract, nft-contract, voting-contract, notary-contract) for fastest setup.

Step 2: Discover Template Details

Use get_template_details to understand template structure and required variables:

// Get details for full project template
get_template_details({
  templateName: 'token-contract'
});

Returns:

• Template metadata
• Required variables (contract name, token parameters, etc.)
• Project structure overview
• Next steps

Step 3: Scaffold Backend (Contract + CLI + Tests)

Use render_template to generate the complete backend:

// Scaffold full project (contract + CLI + tests)
render_template({
  templateName: 'token-contract',
  targetPath: '/path/to/my-token-dapp',
  variables: {
    contract_name: 'GameToken',
    token_name: 'Game Coin',
    token_symbol: 'GAME',
    decimals: '18',
    max_supply: '1000000',
    license: 'MIT'
  }
});

Result:

my-token-dapp/
├── contract/           # Solidity contracts + Foundry
│   ├── src/
│   │   └── GameToken.sol
│   ├── test/
│   │   └── GameToken.t.sol
│   ├── script/
│   │   └── Deploy.s.sol
│   ├── foundry.toml
│   └── out/          # Compiled artifacts (after forge build)
├── cli/              # Rust CLI

│   │   └── bindings.rs
│   ├── Cargo.toml
│   └── target/       # Built CLI (after cargo build)
└── README.md

Step 4: Add Frontend Layer

Copy the frontend template from assets/frontend-template/ to the project:

# Copy frontend template to project
cp -r assets/frontend-template/ my-token-dapp/frontend/

# Navigate to frontend
cd my-token-dapp/frontend

Result:

my-token-dapp/
├── contract/         # (from Step 3)
├── cli/             # (from Step 3)
└── frontend/        # NEW: React + Vite + viem
    ├── src/
    │   ├── components/
    │   │   ├── WalletConnect.tsx
    │   │   └── NetworkInfo.tsx
    │   ├── contracts/
    │   │   └── config.ts    # Configure contract here
    │   ├── lib/
    │   │   ├── chains.ts    # pod network config
    │   │   └── wagmi-config.ts
    │   ├── App.tsx
    │   └── main.tsx
    ├── package.json
    ├── vite.config.ts
    └── .env.example

Step 5: Configure Frontend Integration

5a. Install Frontend Dependencies

cd frontend
npm install

5b. Configure Environment

cp .env.example .env

Update .env:

VITE_MIDNIGHT_RPC_URL=wss://rpc.testnet-02.midnight.network
VITE_POD_CHAIN_ID=54321
VITE_CONTRACT_ADDRESS=0x...  # After deployment
VITE_WALLETCONNECT_PROJECT_ID=your-project-id

5c. Add Contract ABI

After compiling contract (cd ../contract && forge build):

// frontend/src/contracts/config.ts
import contractAbi from '../../../contract/out/GameToken.sol/GameToken.json';

export const CONTRACT_ADDRESS = import.meta.env.VITE_CONTRACT_ADDRESS as `0x${string}`;
export const CONTRACT_ABI = contractAbi.abi;

5d. Update Chain Configuration (if needed)

Edit frontend/src/lib/chains.ts to match actual pod network chain IDs.

Step 6: Build and Test Locally

6a. Compile Contract

cd contract
forge build

6b. Test Contract

forge test

6c. Start Frontend Dev Server

cd ../frontend
npm run dev

Open http://localhost:3000

Step 7: Add DApp-Specific Components

Based on the contract type, add custom components to frontend/src/components/:

For Token DApp:

// frontend/src/components/TokenBalance.tsx
import { useReadContract, useAccount } from 'wagmi';
import { CONTRACT_ADDRESS, CONTRACT_ABI } from '../contracts/config';

export function TokenBalance() {
  const { address } = useAccount();
  const { data: balance } = useReadContract({
    address: CONTRACT_ADDRESS,
    abi: CONTRACT_ABI,
    functionName: 'balanceOf',
    args: address ? [address] : undefined,
  });

  return <div>Your balance: {balance?.toString() || '0'}</div>;
}

// frontend/src/components/TransferForm.tsx
import { useWriteContract } from 'wagmi';
import { useState } from 'react';
import { parseUnits } from 'viem';
import { CONTRACT_ADDRESS, CONTRACT_ABI } from '../contracts/config';

export function TransferForm() {
  const [to, setTo] = useState('');
  const [amount, setAmount] = useState('');
  const { writeContract, isPending } = useWriteContract();

  const handleTransfer = () => {
    writeContract({
      address: CONTRACT_ADDRESS,
      abi: CONTRACT_ABI,
      functionName: 'transfer',
      args: [to as `0x${string}`, parseUnits(amount, 18)],
    });
  };

  return (
    <form onSubmit={(e) => { e.preventDefault(); handleTransfer(); }}>
      <input
        placeholder="Recipient address"
        value={to}
        onChange={(e) => setTo(e.target.value)}
      />
      <input
        placeholder="Amount"
        value={amount}
        onChange={(e) => setAmount(e.target.value)}
      />
      <button type="submit" disabled={isPending}>
        {isPending ? 'Transferring...' : 'Transfer'}
      </button>
    </form>
  );
}

For NFT DApp:

• NFTGallery.tsx - Display owned NFTs
• MintForm.tsx - Mint new NFTs
• NFTCard.tsx - Individual NFT display

For Voting DApp:

• ProposalList.tsx - Show all proposals
• VoteButton.tsx - Cast vote
• Results.tsx - Display voting results

For Auction DApp:

• AuctionTimer.tsx - Display time remaining
• BidForm.tsx - Place bid
• BidHistory.tsx - Show bid history

Step 8: Deploy and Verify

8a. Deploy Contract

Use midnight-deployment-engineer agent for production deployment:

"Deploy my GameToken contract to pod devnet"

Agent will:

• Generate deployment script
• Validate deployment readiness
• Provide deployment instructions
• Verify contract on pod explorer
• Output contract address

8b. Update Frontend Configuration

After deployment, update frontend/.env:

VITE_CONTRACT_ADDRESS=0xDeployedContractAddress

8c. Build and Deploy Frontend

cd frontend
npm run build

Deploy dist/ to Vercel, Netlify, or other hosting.

Template Selection Guide

Choose Based on Complexity

Full Project Templates (Recommended)

Advantages:

• ✅ Complete project structure
• ✅ CLI tools included
• ✅ Foundry tests ready
• ✅ Deployment scripts
• ✅ Best practices enforced

Use for:

• Production DApps
• Rapid prototyping
• Standard use cases (tokens, NFTs, voting)

Simple Templates

Advantages:

• ✅ More customization flexibility
• ✅ Lighter starting point
• ✅ Educational (see each piece)

Use for:

• Custom CLI structure
• Non-standard architectures
• Learning pod network

Best Practices

1. Start with Full Project Templates

Unless you have specific customization needs, always start with full project templates:

// ✅ DO: Use full project template
render_template({
  templateName: 'token-contract', // Includes contract + CLI + tests
  targetPath: './my-dapp'
});

// ❌ DON'T: Use simple template unless needed
render_template({
  templateName: 'token-simple', // Contract only, manual CLI setup
  targetPath: './my-dapp'
});

2. Configure Environment Early

Set up .env files immediately after scaffolding:

# Contract environment
cd contract
cp .env.example .env

# Frontend environment
cd ../frontend
cp .env.example .env

3. Test Contract Before Frontend Development

Always verify contract works before integrating frontend:

cd contract
forge test -vvv

4. Use TypeScript for Frontend

Frontend template uses TypeScript for type safety with viem:

// ✅ DO: Type-safe contract calls
const { data } = useReadContract({
  address: CONTRACT_ADDRESS, // Type: `0x${string}`
  abi: CONTRACT_ABI,
  functionName: 'balanceOf', // Type-checked against ABI
  args: [address]
});

// ❌ DON'T: Lose type safety
const contract = new Contract(address, abi); // ethers.js, less type-safe

5. Respect pod network's Coordination-Free Model

Load references/dapp-architecture.md for pod-specific patterns:

• No block confirmations (use attestations)
• No global transaction ordering
• Time-based logic requires special handling

6. Iterate in Layers

Build and test each layer before moving to the next:

1. ✅ Contract works (forge test passes)
2. ✅ CLI works (cargo test passes)
3. ✅ Frontend integrates (can read contract state)
4. ✅ Full workflow tested (can write to contract)

Common Customizations

After scaffolding, developers often customize:

Frontend Styling

Replace default CSS with:

• Tailwind CSS
• Styled Components
• Material-UI
• Custom design system

Contract Extensions

Add features to base contract:

• Token: Transfer fees, pausable, time-locked minting
• NFT: Metadata URIs, public minting, rarity attributes
• Voting: Weighted voting, quorum requirements, token-gating

Use pod-scaffold-contract skill to add more contracts to existing DApp.

Advanced Features

• Multi-contract DApps (e.g., token + marketplace)
• Backend services (indexers, APIs)
• Subgraphs for data querying
• Mobile app integration

Quick Reference

Workflow Summary:

1. Choose template (token-contract, nft-contract, etc.)
2. Get details (get_template_details)
3. Scaffold backend (render_template)
4. Add frontend (copy assets/frontend-template/)
5. Configure (.env, ABI, chain config)
6. Test (forge test, npm run dev)
7. Add custom components
8. Deploy (use midnight-deployment-engineer)

MCP Server Tools:

• list_templates - Show available templates
• get_template_details - Get template info
• render_template - Generate project

Key Files to Configure:

• frontend/.env - Environment variables
• frontend/src/contracts/config.ts - Contract ABI and address
• frontend/src/lib/chains.ts - pod network chain config (if needed)

Remember: pod network has NO BLOCKS, NO GLOBAL ORDERING. All contracts use order-independent patterns. Frontends must handle attestation-based finality, not block confirmations.
