The Start: 6 Days Left, 1 Big Idea
When I first heard about the Bolt Hackathon, I honestly thought I had missed the boat. The hackathon had been running for weeks, and I only had 6 days left when I decided to jump in. But something inside me said, “Just go for it.” I had been thinking a lot about how AI could help security researchers break down the complexity of Web3 protocols. So I took a step, cleared my schedule, and committed to building something meaningful — solo.
That’s how Code Craft was born.
With millions of dollars in rewards distributed every month through platforms like Code4Arena, Sherlock, Cantina, CodeHawks, and Immunefi, Web3 security research has become a high-stakes, time-sensitive field. As security researchers ourselves, we realized that ~90% of bugs are rooted in the business logic of protocols — the very part that's often buried under scattered documentation and complex smart contracts.
We needed a tool that could cut through the noise — one that reads the code, understands the docs, and explains the business logic as clearly as a seasoned auditor.
That’s what inspired me to build Code Craft:
An AI-powered assistant that helps researchers save time, find bugs faster, and understand Web3 protocols with precision and clarity.
Because without security researchers, Web3 will never be truly safe.
Over the past few years, billions have been lost to protocol exploits, despite massive growth in infrastructure, tooling, and developer adoption:
2021: ~$5.2 billion lost to hacks
2022: ~$3.6 billion lost
2023: ~$1.8 billion lost
2024: ~$2.3 billion lost
2025 (H1): ~$2.17 billion+ already lost
Code Craft is a full-stack AI-powered application that allows users to input any Web3 protocol’s GitHub repo and docs link, and instantly get:
Protocol summaries
Smart contract architecture diagrams
Component-level explanations
Security assessments
And I built the entire application in just 6 days. Sounds insane, right? It was. But Bolt made it possible.

Powered by One Prompt
Here's the wildest part: I built most of the application using a single AI prompt.
Yup, you read that right. This one prompt became the blueprint for Code Craft:
The Prompt That Changed Everything
Build "Code Craft" – An AI Website for Web3 Protocol Analysis
Website Theme & Design
- Color Palette: Strictly black and white (monochrome) for a minimalist aesthetic.
- UX/UI Standards: Clean, elegant, and distraction-free. Use modern animations, Framer Motion recommended. Responsive layout for all devices.
Frontend Development
- Upload Interface: Two input fields (GitHub repo & docs link), no file upload.
- Button: "Analyze Web3 Protocol" (active only when both inputs are filled).
- Output Sections: Protocol Summary, Smart Contract Architecture Diagrams, CoExplanations, andnations, Security Analysis. Each with "View Details" & "Export Report" buttons.
AI Model Integration
- Connect LLaMA 3.3-70B.
- Docs Processing: Extract protocol logic, business/economic models.
- GitHub Analysis: Parse Solidity, build ASTs, detect vulnerabilities, map interactions.
- Output: Synthesized insights from code + docs.
Visualizations
- Use SolidityVisualizer concepts. Generate contract interaction maps, inheritance trees, flow diagrams.
- Render via Mermaid.js, D3.js, or PlantUML (black & white theme).
Backend Logic
- Scrape GitHub and docs URLs
- Extract, parse, clean
- Send structured data to LLama model
- Store results in a database (supabase)
Final Functional Requirements
- Buttons must function as expected
- Export analysis in JSON
- Proper state-based UI feedback
That single, structured prompt gave me the entire architecture of the product: frontend layout, backend logic, AI workflows, and even database structure.
It felt like magic.
One of the best parts of building with Bolt was how seamless the deployment and integration process was.
I absolutely loved how I could:
- Deploy my full-stack project in one click
- Connect Supabase instantly with zero setup
- Publish directly to Netlify with one click
The best part? If I made changes inside the Bolt editor - it automatically updated my GitHub repo and reflected live on the Netlify site without needing to manually do anything. That level of automation saved me hours of time.
And let’s be honest - when building solo, sometimes you try prompts that don’t work or completely mess things up. Bolt has a "Revert Prompt" feature that lets you roll back a prompt execution if the output wasn't what you wanted. That saved me so many times!
Honestly, for me - Bolt is the one and only tool I’d pick to build full-stack AI applications. It’s fast, flexible, and builder friendly.
The Grind: Bugs, Breakdown, and Breakthroughs
But let me be real - it wasn’t easy.
When you're a solo builder working against time, everything hits harder. I had to write the frontend, backend, AI processing logic, and also integrate everything while debugging. And all of this while making sure the user experience didn’t suffer.
I faced:
- GitHub scraping issues
- Docs parsing problems
- Model timeouts and formatting bugs
- "Why isn’t this button working?" moments
- Constructing smart contract architecture diagrams
There were nights I didn’t sleep at all. I remember at 4AM morning, questioning if this was even possible. I wasn’t designing it for beauty, just making sure everything worked perfectly.
One particular issue with model responses formatting almost made me give up.
Huge Thanks to the Bolt Team and Community
ProKai(mentor) helped me solving all of information issues related to the hackathon.
Also, a big shoutout to the Bolt team for:
- Giving free Bolt Pro access (game-changer).
- Keeping the community active and helpful.
Simplicity Over Polish
I knew I didn’t have time to make something flashy - so I chose clarity.
1. Black-and-white theme. Minimalist animations.
2. Everything focused on making the developer’s / security researchers experience fast and frictionless.
The final product?
A working AI app that:
- Accepts GitHub + Docs links
- Analyzes smart contracts and architecture using LLama 3.3-70B
- Generates clean summaries
- Produces diagrams from parsed code (SolidityVisualizer style)
- Detects vulnerabilities
- Exports all this in a JSON report
You can even test it using real-world protocols like:

What’s Next for Code Craft
Now that the hackathon is over, I’m not stopping.
This project is going to be the foundation for a startup.
Security researchers, auditors, and developers spend hours digging through complex protocols. I want to make that process 10x faster with AI.
Here’s the roadmap ahead:
- Support other chains/languages: Rust, Vyper, Cairo, Move
- Plug in a RAG pipeline for high-accuracy insights via Supabase
- Plugin system for custom security rules
- Team dashboards for collaborative audits
- API access for audit firms and bounty platforms
- Real-time risk analysis with on-chain deployment data
But before all that - after a few more improvements and final touches.
I’ll be launching Code Craft publicly soon on social media and inside my own community, Defenders Den.
What’s Defenders Den?
I’m the solo founder of Defenders Den, a growing Web3 security community focused on providing free education to anyone interested in smart contract auditing, protocol security, and blockchain developers.
It’s a space where researchers, learners, and whitehats can grow together.
I built it to support people who want to level up in Web3 security - and I’m proud to say it has already helped many get started in this field.
So launching Code Craft inside Defenders Den means it will instantly reach real auditors and security researchers, the exact audience it was made for.
Final Thoughts: From Idea to Execution in 6 Days
This hackathon was more than just a competition for me - it was a test of:
- My technical speed
- My problem-solving under pressure
- And my ability to trust AI as a co-pilot, not just a tool
I joined with 6 days left and came out with a product I’m truly proud of.
No team, no fancy UI, no overthinking - just raw execution and focus.
Still hesitating about building with Bolt? Trust me, it’s a game-changer. It can change your speed, mindset, and confidence as a builder.
Huge love to @boltdotnew, the mentors, and everyone who made this hackathon possible. This was just the start for Code Craft and for me.
Let’s keep building 💻
