From Monad 101 Session 1 to Web3 MVP: Building with AI Prompts

Hey folks! As a full-stack blockchain dev hustling through hackathons in Hyderabad, I just wrapped Session 1 of Monad 101 Speedrun HYD Edition (Jan 2026). It was a game-changer—focusing on Web3 basics, Monad's parallel EVM, and AI-powered workflows to ship dApps fast. No fluff, just prompts that spit out deployable code. Here's how I built a basic "Counter" Web3 app in under an hour using simple AI instructions.

What I Learned in Session 1

Session 1 dove into Monad testnet setup, wallet integration (MetaMask vibes), and leveraging tools like Cursor IDE or local Ollama models for 10x faster prototyping. The mantra? Prompt > Code > Deploy. Perfect for my late-night hackathon sprints where time = prizes.

Key gems:

  • Monad's 10k TPS EVM means no gas wars—ideal for gaming dApps like my Solana battle arenas.

  • AI handles 80% boilerplate; I tweak for security/tokenomics.

Step-by-Step: AI → Working dApp

1. Smart Contract (Solidity on Monad)

Prompted my local Qwen2.5 (Ollama on MacBook):
"Generate a production-ready Solidity Counter contract for Monad testnet. Include increment/decrement, events, Foundry deploy script. Full files."

Boom—got Counter.sol:

text
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

contract Counter {
    uint256 public count;
    event CountChanged(uint256 newCount);

    constructor() { count = 0; }

    function increment() public { 
        count++; 
        emit CountChanged(count); 
    }

    function decrement() public { 
        require(count > 0); 
        count--; 
        emit CountChanged(count); 
    }
}

Deployed with forge create --rpc-url https://rpc.testnet.monad.xyz in 2 mins.

2. Frontend (Next.js + Wagmi)

Next prompt:
"Next.js 15 app with Wagmi/Viem for Monad testnet. Connect wallet, read/write Counter ABI [pasted ABI]. Tailwind UI, buttons for inc/dec."

AI scaffolded everything: page.tsx with useAccount, useReadContract, useWriteContract. Added testnet RPC, live in npm run dev.

3. Debug & Polish

Error? Prompt: *"Fix Wagmi chainId mismatch on Monad: [error log]."
Fixed gas estimates, added loading states. End-to-end test: Wallet connect → increment → explorer verify. Total: 45 mins.

Pro Tips for Your Builds

  • Prompt like a boss: "Production-ready, full files, ZIP structure, hackathon MVP."

  • Local AI (Qwen2.5-coder:4b) crushes on M4 MacBook—zero API costs.

  • Scale to real hacks: Swap counter for NFT mint or gasless stakes.

  • Tools: Foundry for contracts, Vercel for frontend, Monad explorer for proofs.

This Session 1 hack scaled my Solana gaming dApps to EVM—next up, ZK gaming on Monad. Who's joining Speedrun HYD? Drop your builds below or ping me on X/LinkedIn!
