Chapter 8: Don't Know What to Build? Start Here.

One-line summary: 15 ideas sorted by difficulty, each with the exact prompt to paste into Claude Code right now.

#How to Use This List

Find an idea that sounds fun. Copy the prompt. Paste it into Claude Code with the OP_NET MCP connected. Watch it get built.

Start with EASY if this is your first time. Ship it, submit it, then come back and try something bigger next week.

#EASY — Perfect First Projects

These are simple, impressive, and completely achievable in a single afternoon.

#Token Launch Page

Create and launch your own Bitcoin token. Yes, really.

Pick a name, pick a supply, deploy it. You just made a token on Bitcoin.

Copy this prompt and send it to Claude Code:

"Build me a token launch page using OP_NET. I want to create my own OP20 token called [YOUR TOKEN NAME] with a total supply of [AMOUNT]. The page should have the token name and logo at the top, a description section where I explain what the token is for, the total supply displayed prominently, and a Mint button that lets people connect their OPWallet and mint tokens. Show how many tokens have been minted so far vs total supply with a progress bar. Dark theme with orange accents. Deploy the contract to testnet."

#Bitcoin Price Tracker

A live dashboard showing Bitcoin's price, changes, and trends. Your own Bloomberg terminal.

Copy this prompt and send it to Claude Code:

"Build me a Bitcoin price tracker dashboard. Show the current BTC price in big bold numbers at the top. Below that show the 24-hour change percentage — green if up, red if down. Add a simple chart showing the last 7 days of price history. The whole thing should auto-refresh every 30 seconds. Clean, minimal design. Dark background, white text, one accent color."

#Portfolio Tracker

Connect your wallet and see everything you own in one place.

Copy this prompt and send it to Claude Code:

"Build me a Bitcoin portfolio tracker using OP_NET. There's a Connect Wallet button at the top. After connecting with OPWallet, show the wallet address, BTC balance, and a list of all OP20 tokens the wallet holds with their balances. Display the total portfolio value in USD. Add a refresh button to update everything. Clean card layout, professional look."

#Tip Jar

A page where anyone can send you Bitcoin tips with a message.

Copy this prompt and send it to Claude Code:

"Build me a Bitcoin tip jar app using OP_NET. There's a big Send a Tip button at the top. When clicked, it opens a form where someone enters a Bitcoin amount and a short message. After the tip is sent, show a thank you confirmation. Below the button, display a live feed of all recent tips showing the sender address, amount, and message. Dark theme. Make it feel fun and celebratory — maybe a little animation when a new tip comes in."

#Bitcoin Calculator

Convert between BTC, satoshis, and dollars instantly.

Copy this prompt and send it to Claude Code:

"Build me a Bitcoin unit converter tool. Three input boxes: BTC, Satoshis, and USD. When I type a number in any box, the other two update instantly with the converted amounts. Use the live BTC price for the USD conversion. Add a toggle to switch between light and dark mode. Keep it clean, minimal, and fast. This should feel like a utility you'd actually bookmark and use daily."

#MEDIUM — Once You've Built One

These have more moving parts but nothing you can't handle after your first project.

#Token Vesting Dashboard

Lock tokens with a schedule. Show a visual countdown of when they unlock.

Copy this prompt and send it to Claude Code:

"Build me a token vesting dashboard using OP_NET. The contract lets an owner create vesting schedules for recipients — you set the total token amount, a cliff period (waiting time before anything unlocks), and a linear unlock period where tokens gradually become available. The frontend should show a visual timeline chart of the vesting schedule, how much is currently unlocked, how much is still locked, and a Claim button to withdraw unlocked tokens. Owner gets an admin panel to create and manage vesting schedules. Connect with OPWallet. Professional, data-heavy design."

#On-Chain Bounty Board

Post tasks with Bitcoin rewards. Someone completes the work, claims the bounty.

Copy this prompt and send it to Claude Code:

"Build me an on-chain bounty board using OP_NET. Anyone can post a bounty by depositing tokens into the contract with a title, description, and reward amount. Builders can submit their work for a bounty. The bounty poster reviews submissions and approves a winner, which releases the escrowed tokens to them. Frontend shows a list of open bounties with titles, descriptions, reward amounts, and deadlines. Users connect their OPWallet to post bounties or submit work. Clean, professional layout like a job board."

#Analytics Dashboard

Track OP_NET stats in real time — transactions, contracts, activity.

Copy this prompt and send it to Claude Code:

"Build me an OP_NET analytics dashboard. Show live network stats: recent transactions, number of deployed contracts, block height, and mempool status. Add charts showing transaction volume over time. Display a table of recent contract deployments with addresses and timestamps. Auto-refresh every 60 seconds. This should feel like a blockchain explorer but cleaner and more visual. Dark theme, data-heavy, lots of numbers and charts."

#NFT Minting Page

Let people mint digital collectibles on Bitcoin.

Copy this prompt and send it to Claude Code:

"Build me an NFT minting page using OP_NET. I'm creating a collection called [YOUR COLLECTION NAME] with [AMOUNT] NFTs. The page shows a preview image of the collection, the collection name, mint price, and how many have been minted vs total supply with a progress bar. A big Mint Now button lets users connect their OPWallet and mint. After minting, show a success message with their NFT details. Clean, modern design. Make it feel like an exclusive drop."

#DAO Treasury Viewer

See exactly what a DAO owns — balances, inflows, outflows, all transparent.

Copy this prompt and send it to Claude Code:

"Build me a DAO treasury dashboard using OP_NET. It connects to a treasury wallet address and shows all token balances, recent inflows and outflows as a transaction list, and a simple chart of treasury value over time. No wallet connection needed for viewing — it's a public transparency tool. Add a search bar to look up any wallet address. Clean, minimal, data-focused design."

#ADVANCED — For the Ambitious

These are bigger builds. More iteration, more moving parts. But still totally buildable with Bob.

#Token Launchpad

A platform where anyone can create and launch their own token through your site.

Copy this prompt and send it to Claude Code:

"Build me a token launchpad platform using OP_NET. Users connect their OPWallet and fill out a form: token name, symbol, total supply, description, and optional logo upload. The platform deploys a new OP20 contract for them with those parameters. After deployment, they get a shareable page for their token showing all the details and a mint/buy interface. The homepage shows a directory of all tokens launched through the platform with search and filter. Think pump.fun but on Bitcoin. Clean, modern design."

#DEX Interface

A swap page where people trade tokens using OP_NET.

Copy this prompt and send it to Claude Code:

"Build me a minimal token swap interface using OP_NET and MotoSwap. Two token selector dropdowns at the top, an input amount field, and a Swap button. Show the estimated output amount, exchange rate, and price impact below the inputs. Users connect their OPWallet to execute swaps. Add a recent transactions list at the bottom. Clean and modern like Uniswap. Include slippage tolerance settings in a gear icon menu."

#Staking Dashboard

Stake tokens, earn rewards, track everything in one place.

Copy this prompt and send it to Claude Code:

"Build me a staking dashboard using OP_NET. Users connect their OPWallet, deposit tokens to stake, and earn rewards over time. The dashboard shows: current staked balance, accumulated rewards, APY percentage, and a rewards history table. Big Stake and Unstake buttons with amount inputs. A chart showing staking rewards earned over time. Professional, data-heavy dark theme. The contract should track deposits per user and distribute rewards proportionally based on stake size and duration."

#NFT Marketplace

Browse, buy, and sell NFTs on Bitcoin.

Copy this prompt and send it to Claude Code:

"Build me an NFT marketplace using OP_NET. A grid of NFT cards showing image, name, collection, and price. Click any NFT to see full details, owner history, and a Buy button. Users connect their OPWallet to buy or list their own NFTs for sale. Add a My Collection tab showing NFTs I own with a Sell button on each. Include search, category filters, and sort by price or recency. Modern marketplace design like OpenSea but cleaner."

#On-Chain Voting

Full governance system. Create proposals, vote with tokens, execute results.

Copy this prompt and send it to Claude Code:

"Build me a governance voting system using OP_NET. Token holders can create proposals with a title and description. Other token holders vote For or Against, with their voting power based on their token balance. Proposals have a voting period set in blocks. If quorum is met and majority votes For, the proposal passes. The frontend shows active proposals with live vote tallies and progress bars, closed proposals with results, and a Create Proposal form. Users connect their OPWallet to vote. Professional, clean governance dashboard look."
