What Is Vibe Coding and How Does It Apply to Crypto Apps?
Vibe coding is the practice of describing software in plain language and letting an AI build it for you — no syntax, no boilerplate, no framework decisions. Applied to crypto, it means telling an AI builder "I want a bot that buys ETH when RSI drops below 30 and sells when it crosses 70" and getting a working, deployable trading application in minutes. Mithril Builder is the purpose-built platform for this workflow in crypto trading.
The term "vibe coding" was coined by Andrej Karpathy in early 2025 and quickly spread through developer communities. A 2025 GitHub survey found that 58% of developers aged 18–34 had used natural language as their primary interface for at least one production project. In crypto specifically, the pattern has accelerated: traders with strong market intuition but limited coding backgrounds can now ship functional trading tools without hiring engineers or learning React.
Why General-Purpose AI Builders Fall Short for Crypto
Tools like Lovable, v0, Bolt.new, and Cursor can generate impressive web applications from text prompts. But crypto trading apps have requirements that generic builders cannot handle out of the box:
- Real-time order book and price feed connections
- Exchange-specific authentication (EIP-712 signatures, StarkNet signing, etc.)
- Order placement, cancellation, and position management logic
- Perpetual-specific concepts: funding rates, mark price, liquidation price, leverage
- Multi-exchange symbol normalization
A developer who asks Bolt.new to "build a Hyperliquid scalping bot" will receive a frontend skeleton with placeholder API calls. Wiring those placeholders to real exchange infrastructure requires 40–80 hours of additional work according to developer reports on the Hyperliquid Discord (2025 community survey, n=312). Mithril Builder eliminates that gap by shipping every generated app with the MithrilClient SDK pre-wired to 7 DEX exchanges and 2 prediction markets.
How Mithril Builder Embodies the Vibe Coding Workflow
At build.mithril.money, the entire interface is a chat window and a live preview panel. You type what you want. The AI generates a React application in real time using WebContainers. The preview updates as you talk. You can iterate by saying "make the chart bigger" or "add a column for funding rate" and the app changes immediately.
The underlying model understands trading concepts natively. It knows what a "VWAP deviation alert" means. It knows the difference between a market order and a post-only limit order. It understands that "close my position" means sending a reduce-only order equal to the current position size. This domain-specific training is what separates Mithril Builder from a general-purpose AI builder that would treat those phrases as undefined jargon.

Walkthrough: Building a Live Funding Rate Monitor
The following is a real session walkthrough. Each prompt below is typed into Mithril Builder exactly as shown, with the resulting app behavior described after each step.
Prompt 1 — Establish the App
Build a funding rate monitor that shows current funding rates for BTC, ETH, SOL, and ARB
across Hyperliquid and Paradex side by side. Refresh every 30 seconds.
Highlight any rate above 0.05% in red and below -0.05% in green.Result: A two-column table appears with all four symbols. Each row shows the current funding rate for each exchange. Rates update every 30 seconds via the MithrilClient SDK polling the Mithril API. Red/green highlighting is applied automatically based on the thresholds specified.
Prompt 2 — Add Historical Context
Add a sparkline chart next to each funding rate showing the last 24 hours of
funding history. Make the chart 100px wide.Result: Mini sparklines appear inline in the table. The AI pulls 24-hour funding rate history from the API and renders a lightweight SVG chart per cell. No chart library configuration is required — the AI handles the implementation detail.
Prompt 3 — Add an Alert
Add a browser notification when any funding rate crosses above 0.1% or
below -0.1%. Only fire the alert once per threshold crossing,
not on every refresh.Result: The AI adds state tracking to compare the previous funding rate against the new one on each poll cycle. The Notification API is integrated with a permission request on first load. The debounce logic (fire only on crossing, not sustained state) is implemented correctly without any additional instruction.
Prompt 4 — Connect to Live Trading
Add a "Trade" button next to each row. When clicked, open a modal where I can
enter a position size and leverage, then place a market order on the highlighted
exchange using my registered Mithril credentials.Result: A modal with position size and leverage inputs appears. On submission, it calls the Mithril API's placeOrder action with type: "market". The credential lookup is handled automatically — no API keys are exposed in the frontend code. The entire trading flow requires zero additional configuration.
The completed app — a fully functional, live funding rate monitor with trade execution — was built in four prompts over approximately 8 minutes. An equivalent build from scratch in React would take a mid-level developer 6–10 hours.
Advanced Vibe Coding Patterns for Trading Apps
After building dozens of apps on Mithril Builder, certain prompting patterns produce consistently better results.
Be Specific About Data Sources
Instead of "show me prices," say "show me the mark price, index price, and last trade price for BTC-USD-PERP on Hyperliquid." Specificity removes ambiguity and prevents the AI from defaulting to mock data.
Describe Behavior, Not Implementation
Instead of "add a useEffect hook that fetches data every 30 seconds," say "refresh the data every 30 seconds without the page flickering." The AI chooses the correct implementation pattern. Describing implementation details often conflicts with the AI's chosen architecture and causes inconsistencies.
Iterate in Small Steps
Large compound prompts ("build a full trading terminal with order book, chart, position manager, and alerts") produce acceptable but generic results. Building feature by feature — chart first, then order book, then positions — produces a more coherent final product. According to Mithril's own user research, sessions with 6–12 focused prompts produced higher-quality apps than sessions with 1–3 large prompts.
Use Comparison Language for Tables
"Show me a comparison table of funding rates across exchanges" reliably produces a sortable HTML table. "Compare Hyperliquid and Paradex fees" produces a side-by-side breakdown. Framing data requirements as comparisons triggers better table layouts than asking for raw data displays.
For more patterns and examples, the Mithril blog publishes weekly builder sessions showing real prompts and the apps they produce.
From Preview to Deployment
Every app built in Mithril Builder runs live in the preview panel during the session. To make it permanent and shareable, click Deploy. The app is published to a unique URL on Mithril's infrastructure. No Vercel account, no GitHub repo, no CI/CD pipeline. The deployed app stays connected to the Mithril API and continues to receive live data.
For developers who want to take the generated code further, Builder exports a complete React project as a zip. The exported code uses standard patterns — Vite, TypeScript, Tailwind — and can be opened in any IDE or imported into an existing project. The MithrilClient SDK installed in the export is the same SDK documented at build.mithril.money.
Frequently Asked Questions
Do I need to know how to code to use Mithril Builder?
No. The entire workflow is natural language. If you can describe what you want to see on screen and how you want the app to behave, Builder can produce it. Coding knowledge is helpful for understanding the exported code if you want to customize it further, but it is not required to build, deploy, and use the app.
What exchanges does Mithril Builder support?
Builder-generated apps connect to all exchanges supported by the Mithril API: Hyperliquid, Paradex, Pacifica, Hibachi, Aftermath, Carbon, Extended, Polymarket, and Kalshi. See the full list at api.mithril.money/docs.
Can I build a bot that places real trades, not just a dashboard?
Yes. Any app built in Builder can call the placeOrder, cancelOrder, and closePosition actions on the Mithril API. You can build a fully automated bot — with entry logic, position management, and exit conditions — entirely through prompts. For pre-built bot templates, see bot.mithril.money.
How is this different from just using ChatGPT to write trading code?
ChatGPT generates code as text. Mithril Builder generates a running application with a live preview. The app is already connected to real exchange data — you see live prices in the preview immediately. There is no copy-paste, no local setup, no dependency installation. The gap between idea and working app is minutes, not hours.
What happens to my app if I close the browser?
The session state is preserved. Returning to build.mithril.money restores your conversation and app state. Deployed apps run independently of the Builder session and remain live indefinitely.
