On August 23rd and 24th 2025 we held Shapecraft 2: the world's largest NFT hackathon. More than 180 builders participated worldwide to build with 1 simple guideline:
Build an AI x NFT project on Shape
10 winners shared more than 1,000,000 $SHAPE and some Apple gear. We sat down with them to learn more about who they are and the projects they brought to life.
quietloops
I'm Joe aka @quietloops aka @josdotph and I built "Katachi Gen" with longtime close collaborator Sembo aka @1000b. We are engineers and artists that work between physical and digital mediums. Sembo, who's from Tokyo, is also one half of the artist duo Exonemo. We are also employees #0 and #1 of Infinite Objects, a company building physical expressions of digital content for the last 7 years.
We built Katachi Gen, a project that transforms your participation on Shape into an expression of unique 3D origami patterns, generated through AI sentiment analysis and algorithmic art curation.
"Katachi" ( カタチ ) means "Shape or Form", and "Gen" ( ゲン ) means to "appear or manifest", so you could translate Katachi Gen to mean "Shape Revealed". Each generative origami pattern reflects your personal collecting journey on Shape, creating a one-of-a-kind textured origami pattern, which can be printed from on-chain data and folded IRL. Katachi Gen reveals a digital and physical artifact that represents a snapshot of your on-chain identity. A Shape of your Shape.
How it works: Log in to katachi-gen.com with a wallet holding a Shape Stack NFT
The app then analyzes your wallet's Shape participation including medals, collections, and all NFTs. The collector is then asked: What does collecting art mean to you? What is your favorite thing about collecting on Shape? Answer this question as honestly or humorously as you'd like, and our MCP server will evaluate your response for sentiment and keywords, and then curate 8 artworks from your collection that heuristically match your input.
A unique 2D origami pattern (FOLD file) with a texture composed from the AI-curated set of art is then generated. Finally, the collector previews the output and then mints an self-contained HTML file featuring an interactive 3D visualization of your origami form, representing your collecting and sentiment about your journey on Shape.
Shapecraft was super fun, primarily because the community of builders and artists working on Shape are super thoughtful and curious, but also the challenge of using AI technology with art was something new for us. The team at Shape was really helpful, starting well before the 2-day hackathon. In particular @williamhzo's Shape MCP server template was super valuable as we jumped in to actually building that weekend. I love that being part of a hackathon means the codebase is published and effectively open-source; anyone can check it out on git: github.com/jmsaavedra/katachi-gen.
Really appreciated that some of the artist judges took the time to meet on discord leading up to the hackathon, and listened to and shared ideas around their approach to AI + art. The support even post-hackathon, as we move towards mainnet deployment, has been great, especially in terms of auditing our contract. Using AI to help build our AI project was super fun, and we were able to launch on testnet by the end of the hackathon but we'll be launching our public mint the first week of November. Good Shape!
Ubinhash
I'm @ubinhash and I'm just a dev who likes blending tech and art. I've been actively exploring Shape for a while, and I love how supportive the ecosystem is for builders. During Shapecraft 1 I built ZeroSumPact, a fully on-chain strategy game, which I later won and launched on mainnet. I prefer to keep my personal life and online presence separate, so I'd rather let my projects speak for me :)
I built MintDuel, an experimental project exploring how agent-enabled mint pricing could work in practice. Players will have to play a simple 3-round game with the AI agent and the outcome (health of the agent) will be proportional to the price you pay.
Basically, the lower you reduce the agent's health, the less you pay. With zero health = free mint, full health = full price, and 30% health meaning you only pay 30% of the price.
In this simple game, the player will have to equip 3 OTOMS which have mass that adds up to 100. Then in each round players can pick one OTOM, then choose between <attack> and <charge>. The agent then has three move options <defend>, <flip-charge> and <recover>.
<attack> reduces agent's health by the mass value, <charge> will boost the next attack. But here's the twist, the agent will try to guess your move and respond accordingly. The agent may <defend> to counter the attack, but if they've guessed incorrectly and you were actually charging, they will suffer half of the charge.
To keep the game fair, each round is structured so that no one can see the other's move in advance.
- The agent first commits to its move with a secret hash.
- Then the user submits their move.
- Finally, the agent reveals its move. The effect is calculated and we move to the next round.
Since the agent is an llm, the user is also free to influence the agent's move by bluffing or ask the agent to reveal (it probably won't or might bluff) it's move via clever prompting. (If anyone is interested in seeing this on mainnet feel free to let me know.)
I think this would be an interesting new paradigm of mint pricing, where we put the ability to price a mint in the hands of an ai agent. It could take the form of a different game, or a different type of agent.
Shapecraft 2 was a fun experience! I would like to thank @williamhzo for hosting such a great hackathon and providing us with enough tools and guidance to complete our project in such a tight timeframe. Having more of these short-format hackathons on different themes is also a great way to explore new topics and spark fresh ideas.
Zech
I'm Zech (@Zech_Ng), your regular coder/tinkerer who has experience in gaming, fintech, ecommerce and web3.
I built a collaborative story telling platform that allows users to create text stories, comics or videos.
As I had also taken part in ShapeCraft 1, it was not new to me. I like that the organizers and community are very engaged and supportive throughout the journey. It was also helpful that AI coding agents have improved vastly during this period, which allowed more effort to be spent on the idea itself.

I'm atrnd (@AT_Rnd_Shape), a self-motivated builder, focusing on web3 security, game design & experimental tech.
The first phase/block of an AI-driven curator for NFTs using personas to determine if a set of Shape projects matches the user's taste & analytics.
Shapecraft 2 was awesome! It was quite short, but the vibes & support were great - huge shoutout to William!
CipherKuma & CipherBonney
We are anons who build web3 projects that help solve a problem or help people live a better life.
We built kaiju no. 69, a degen way to support people in need by trading NFTs on SHAPE.
As the timeline was short we couldn't build out the application fully, but the hackathon gave me a vision to work on further.
Allen - Deeple Tiles
Hey! I'm Allen (@allenjosephaj), a builder who loves experimenting at the intersection of design, code, and brainrot. I'm interested in building products that no-one uses. Thankfully, I've built a few side projects which generate revenue!
I built Deeple Tiles — a rhythm game that blends AI, on-chain logic, and music into a living experiment. It's powered by an autonomous AI musician that composes melodies, mints them as on-chain music cards (ERC-721s), and challenges players to perform them.
Instead of treating AI × NFTs as just generative art, Deeple Tiles pushes the idea further — into AI agents as creators, curators, and challengers. Players hit keys as notes fall, while every playthrough and melody is recorded on-chain as part of a growing creative ecosystem.
Honestly, Shapecraft 2 was amazing. The community, the feedback loops, and the focus on creativity-first building made it feel like a true playground for ideas. It was less about competition and more about exploring what's possible and that made it super motivating to build. Shoutout to William for being supportive!
Quixuote
My name is Quixuote (@Donquixuote), and I built ShapeTCG, a battle arena that utilizes AI to transform your NFTs into playable cards.
The Shapecraft experience is always amazing. The challenges push creators to learn and challenge themselves thus furthering our skills. I've always enjoyed the experience for the learning that takes place to get to the goal that I create. The Shape team also provides many opportunities such as office hours to learn from them. The overall experience was a big "I understand it now" moment for me learning how AI integration works and how I can now use that knowledge to further my own projects.
Summermaxi
Hi Summermaxi.eth (@SummerMaxis) here. Geologist by Academics but part time developer and designer. I love minerals and collect them apart from NFT's.
I built mintshare.fun for Shapecraft which is an AI assistant to help you find out who your top collectors are and also to find whose artwork you have collected most. This concept came to me similar to Kaito Mindshare to see how top collectors collect emerging artists' artwork or find early artists' work.
I loved Shapecraft 2. It was a two day hackathon so it was pretty intense. I didn't sleep at all. The team was very welcoming in alleviating any doubts. It was pretty much a great experience and the concept of integrating AI with NFT was nice.
Samueldans0
I'm Samuel (@samueldans0), a full-stack engineer in Web3, and I built Reshape - a GenAI NFT platform for artists, collectors, and vibe creators.
Reshape is an AI-powered NFT platform that allows artists and collectors to generate, mint, and curate art into unique galleries, all with the help of a Curator Agent. By combining generative AI with NFTs on Shape, we're unlocking new creative possibilities and giving collectors verifiable ownership of one-of-a-kind vibes.
The Shapecraft experience was great! The docs were super developer-friendly and easy to navigate. And honestly, the starter kit was a game-changer. It made building my project incredibly fast.
