Build a Blockchain Explorer UI with AI

TL;DR: Replay uses video analysis and Gemini to rapidly generate a functional Blockchain Explorer UI, understanding user intent beyond just visual elements.

The race to build the next generation of Web3 interfaces is on. But manually coding complex UIs, especially for blockchain explorers, is a slow and error-prone process. Traditional screenshot-to-code tools fall short because they lack the crucial understanding of user behavior and application logic. We need a faster, smarter way to translate ideas into working code.

The Problem: Manual UI Development for Blockchain Explorers#

Building a blockchain explorer UI from scratch is a daunting task. It requires:

• •Understanding complex blockchain data structures.
• •Designing intuitive interfaces for displaying transactions, blocks, and addresses.
• •Implementing robust error handling and data validation.
• •Ensuring performance and scalability for handling large amounts of data.

This process often involves countless hours of manual coding, debugging, and iteration. Even with component libraries and UI frameworks, the sheer complexity of blockchain data makes it challenging to build a user-friendly and functional explorer.

The Solution: Behavior-Driven Reconstruction with Replay#

Imagine being able to generate a fully functional blockchain explorer UI simply by recording a video of yourself interacting with a prototype or even a competitor's explorer. That's the power of Replay. Replay is a video-to-code engine that uses Gemini to reconstruct working UI from screen recordings. Unlike traditional screenshot-to-code tools, Replay understands what users are trying to do, not just what they see. This "Behavior-Driven Reconstruction" approach unlocks unprecedented speed and accuracy in UI development.

Key Advantages of Replay#

• •Video as Source of Truth: Replay analyzes video, capturing user behavior and intent.
• •Multi-Page Generation: Generates complete, multi-page applications from a single video.
• •Supabase Integration: Seamlessly integrates with Supabase for data storage and retrieval.
• •Style Injection: Allows you to inject your own CSS or Tailwind styles.
• •Product Flow Maps: Automatically generates flow maps to visualize user journeys.

Building a Blockchain Explorer UI: A Step-by-Step Guide#

Let's walk through the process of building a basic blockchain explorer UI using Replay.

Step 1: Record Your Workflow#

Record a video demonstrating the desired functionality of your blockchain explorer. This could involve:

• •Navigating to different pages (e.g., transaction details, block details, address information).
• •Searching for specific transactions or blocks.
• •Filtering data based on different criteria.

The clearer and more comprehensive your video, the better the resulting code will be.

💡 Pro Tip: Speak clearly while recording. Narrating your actions helps Replay better understand your intent.

Step 2: Upload to Replay#

Upload your video to the Replay platform. Replay will automatically analyze the video and generate the corresponding code.

Step 3: Review and Customize the Generated Code#

Once Replay has finished processing the video, you can review and customize the generated code. Replay provides a visual editor where you can make changes to the UI, adjust styling, and add custom logic.

typescript
// Example generated code for fetching transaction details
const fetchTransactionDetails = async (transactionHash: string) => {
  try {
    const response = await fetch(`/api/transactions/${transactionHash}`);
    const data = await response.json();
    return data;
  } catch (error) {
    console.error("Error fetching transaction details:", error);
    return null;
  }
};

Step 4: Integrate with Your Blockchain Data Source#

Integrate the generated UI with your blockchain data source. This could involve connecting to a blockchain API or querying a database containing blockchain data.

Step 5: Deploy Your Blockchain Explorer#

Deploy your blockchain explorer to a hosting platform of your choice.

Comparison with Existing Tools#

How does Replay stack up against existing UI development tools?

As you can see, Replay offers a unique combination of speed, accuracy, and ease of use that is unmatched by traditional UI development tools.

Addressing Common Concerns#

How accurate is the generated code?#

Replay's accuracy is significantly higher than screenshot-to-code tools because it analyzes video and understands user behavior. However, the accuracy of the generated code depends on the quality of the input video. Clear, well-defined videos will result in more accurate code.

⚠️ Warning: While Replay strives for perfection, manual review and adjustments are often necessary, especially for complex UIs.

Can Replay handle complex blockchain data structures?#

Yes, Replay can handle complex blockchain data structures. However, you may need to provide additional context or guidance to Replay to ensure that it correctly interprets the data. This can be done through code customization or by providing more detailed video examples.

What if I don't have a video to start with?#

You can create a simple prototype or even use a competitor's website as a starting point. Record a video of yourself interacting with the prototype or website, and Replay will generate the corresponding code.

📝 Note: Be mindful of copyright restrictions when using competitor websites as inspiration.

Advanced Features: Supabase Integration and Style Injection#

Replay offers several advanced features that can further accelerate your UI development process.

Supabase Integration#

Replay seamlessly integrates with Supabase, a popular open-source alternative to Firebase. This allows you to easily store and retrieve blockchain data using Supabase's powerful database and authentication features.

Style Injection#

Replay allows you to inject your own CSS or Tailwind styles into the generated UI. This gives you complete control over the look and feel of your blockchain explorer.

html
<!-- Example of injecting Tailwind CSS -->
<link href="https://cdn.jsdelivr.net/npm/tailwindcss@2.2.19/dist/tailwind.min.css" rel="stylesheet">

<div className="bg-gray-100 p-4 rounded-md shadow-md">
  <h2 className="text-xl font-semibold mb-2">Transaction Details</h2>
  {/* ... */}
</div>

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced features and usage. Check the Replay pricing page for the latest details.

How is Replay different from v0.dev?#

While v0.dev is a powerful AI code generation tool, Replay distinguishes itself by using video input and focusing on behavior-driven reconstruction. This allows Replay to understand user intent and generate more accurate and functional UIs, especially for complex applications like blockchain explorers. Replay captures the process of using an interface, not just the static end result.

What kind of blockchain explorers can I build with Replay?#

You can build a wide range of blockchain explorers with Replay, from simple transaction viewers to complex analytics dashboards. The only limit is your imagination!

What are the limitations of Replay?#

Replay is still under active development, and there are some limitations. It may not be able to handle extremely complex UIs or highly customized components without manual intervention. However, the Replay team is constantly working to improve the accuracy and capabilities of the platform.
