IDEAS TO BUILD
Build Unstoppable apps
-
Build a web app where creators are able release generative art that uses existing Forma NFTs as 'inputs'
It would allow for creators to make it such that if a minter owns a certain NFT collection, or a certain type of NFT within that collection, it will have some influence over the art that they mint. If I already own a Mammoth NFT with a particular trait, for example, perhaps it improves my likelihood of minting a 'rare' piece.
-
Create a Video NFT DEX platform that enables creators to tokenize, mint, and trade video and image NFTs, incorporating gamified incentives through a custom gas token that serves as loyalty points
-
Build a DEX integrated with AI-powered trading agents that analyze market data, detect arbitrage opportunities, and execute trades automatically. Users can assign their agents specific strategies, configure risk levels, and allocate funds. The agents dynamically adapt to real-time market conditions, optimizing trading performance.
-
Sleep2Earn tackles the growing issue of sleep deprivation in modern society. Poor sleep negatively impacts productivity, mental health, and overall well-being. The app incentivizes better sleep by rewarding users with tokens for meeting predefined sleep goals, verified securely using zkTLS. Users gain rewards without compromising sensitive health data, ensuring privacy.
-
LazyDev incentivizes open-source contributions by rewarding developers for submitting Pull Requests (PRs) and fixing bugs. Using zkTLS, it validates the authenticity of contributions without revealing unnecessary personal or project-sensitive details. The platform gamifies development, promoting collaboration and quality.
-
Build a fully onchain CLOB DEX, spot or perps. A key challenge here is building an efficient matching engine so the transaction fees don’t increase with a large book.
-
Onchain money legos that utility a fully onchain orderbook. For example, an onchain decentralised perps cash-and-carry strategy, like Ethena.
-
Build a Venmo-style app where users can send and receive payments in USDC, leveraging Privy wallets to manage stablecoins seamlessly. The app could also use Bridge’s API to allow users to easily convert fiat USD into USDC, enabling on-chain transactions without complex wallet setup or external exchanges.
-
Build a decentralized prediction market where users can place bets based on information pulled from social platforms like Farcaster, LinkedIn, GitHub, or Discord. For example, users could bet on which LinkedIn post will get the most reactions, or which GitHub project will gain more stars in a week.
-
A lightweight, social prediction market platform that lets small friend groups bet on personal goals or outcomes. For example, guess who will lose the most weight by the end of the month, or which BD friend will land the most logo x logo announcements (😉 just kidding). It encourages friendly competition, accountability, and helps small communities use token-based predictions as social motivation.
-
This platform enables researchers, companies, or independent developers (“campaign creators”) to launch data collection campaigns for AI training. Whether the target data is health metrics, shopping receipts, or browsing behaviors, creators can specify what type of data they need and define quality criteria.
Users who choose to participate share their data and get rewarded with tokens. The platform incorporates mechanisms to ensure data authenticity, privacy, and proper verification to maintain data quality and trust between creators and contributors.
-
DeFi is a pillar of crypto, and many innovations can be realized on an appchain, such as native yield, MEV capture, or specific transaction prioritization logic. Examples given.
-
The focus is on creative ideas that can attract users without deep DeFi knowledge. Examples given.
-
A messenger app that lets users send text-based messages. Inspired by our earlier experiment with Modular Chat (repo), this version introduces a public forum where users can set up usernames and engage in a discussion.
-
Flame is the home for Celestia Native DeFi, it is an EVM powered by the Astria Sequencing Layer, with Celestia Underneath. As an EVM rollup that uses TIA as its native asset, there is a world of DeFi protocols that can be built on Flame that leverage Astria’s unique tech stack.
-
Using Rollkit x Artela EVM++, create an application that harnesses the power of web proofs to use off-chain data in interesting ways on-chain.
-
Develop a Telegram mini app or bot that accepts user-defined goals or prompts and spins up an AI agent to achieve them.
-
Build a Yield Surge Protocol (YSP). This is a protocol designed to rapidly bootstrap liquidity on Eclipse by drastically lowering the barrier to entry and incentivizing early adopters.
-
Build a King of the Hill-style onchain game where players compete to solve a PoW puzzle. Players interact with a smart contract to try and generate the lowest hash in each block, with the winner receiving a reward.
-
This is the famous Million Dollar Homepage project reimagined for web3. Build a fully onchain web server powering a collaborative HTML website in contract storage. Users pay to add a page to the website, which they can customize and fill with any content they want.
-
Professionals often want to host events or share insights from their workplace while maintaining anonymity. This platform allows verified employees from companies to host events and share insights without revealing their identity.
Build onchain worlds

-
In the deck-building genre, you start with a minimal starter deck of a few cards, from which you draw cards. During the course of the game, you have the opportunity to add more cards to your deck, which you will able to draw during the game.
-
A fun fully onchain 2D tower defense game, in the style of Elemental TD, Bloons TD, Kingdom Rush, Isle of Arrows, and a bunch of Warcraft 3 / Starcraft 2 custom maps.
In such games, players have a token budget that allows them to purchase and put down towers along a predefined path. The game proceeds in rounds where waves of monster try to make it through the path and damage the player's castle. The goal is to use the towers to shoot the increasingly strong waves of monsters that come up. Killing monsters gives out the token that allows buying more tower.
Your game has to be fully-onchain (all the game logic lives in smart contracts).
-
A fully onchain virtual pet game that brings the nostalgic 90s Tamagotchi experience to Web3, where each pet is a unique digital entity living entirely on the blockchain.
-
A decentralized version of the popular game Clash of Clans, where AI agents autonomously manage player villages and defenses. Players can deploy AI-powered strategies to raid and defend in a competitive environment. AI agents can also work together and form autonomous alliances.
-
Create a simple turn-based territory capture game on an 8x8 grid. Two players take turns claiming adjacent squares to grow their territory.
-
Build a checkers game with two rulesets that demonstrates the power of state verification and forking.
-
Create an arcade-style gaming experience featuring popular games like Snake, Tetris, or Minesweeper.
-
Imagine a country prospering with growth & infrastructure, only to be completely virtual, AI agents live here instead of humans, and they run the economics and the govern the country. Transform AI systems into self-sovereign economic entities through blockchain technology, enabling direct participation in the digital economy without human intermediaries.
Upgrade the internet
-
Twitter is entirely centralized and Farcaster doesn't fully inherit blockchain security. Using Chopin Framework, you can build a social network that inherits the full security of Celestia.
-
Imagine ImgFlip onchain. Users can create and customize meme templates, fork each others' memes, mint them as NFTs and more. The possibilities are endless.
-
Create a Prism service that adds Twitter, or any other website source, as accounts on Prism. These accounts can then be used as a source for any application built on top of Prism.
-
HTTPS is not as secure as you think. Securing users’ web browsing from MITM attacks is now possible thanks to Prism, if you build a browser extension to enable it.
-
A ZK-powered image provenance stack that enables developers to prove and verify the authenticity and edit history of digital media, restoring trust in an era of AI-generated content.
-
Build with ZK a powerful stack for exchanges to prove reserves and liabilities transparently, eliminating opacity in crypto through verifiable solvency.
