Sui Decompile Skill

Fetch decompiled source code for on-chain Sui Move packages via block explorers.

GitHub: https://github.com/EasonC13-agent/sui-skills/tree/main/sui-decompile

Suivision (Preferred)

May have official verified source code when available.

URL: https://suivision.xyz/package/{package_id}?tab=Code

Browser workflow:

1. browser action=open profile=openclaw targetUrl="https://suivision.xyz/package/{package_id}?tab=Code"
2. Click module tabs on the left if multiple modules exist
3. Extract code:

() => {
  const rows = document.querySelectorAll('table tr');
  const lines = [];
  rows.forEach(r => {
    const cells = r.querySelectorAll('td');
    if (cells.length >= 2) lines.push(cells[1].textContent);
  });
  return lines.join('\n');
}

Suiscan (Alternative)

URL: https://suiscan.xyz/mainnet/object/{package_id}/contracts

Browser workflow:

1. browser action=open profile=openclaw targetUrl="https://suiscan.xyz/mainnet/object/{package_id}/contracts"
2. Click "Source" tab (default may show Bytecode)
3. Click module tabs if multiple modules
4. Extract code:

() => {
  const rows = document.querySelectorAll('table tr');
  const lines = [];
  rows.forEach(r => {
    const cells = r.querySelectorAll('td');
    if (cells.length >= 2) lines.push(cells[1].textContent);
  });
  return lines.join('\n') || 'not found';
}

Multiple Modules

Packages like DeepBook (0xdee9) have multiple modules:

1. List module tabs from sidebar
2. Click each tab, extract code
3. Save to separate .move files

Examples

Use with Other Skills

This skill works great with the Sui development skill suite:

• sui-move: Write and deploy Move smart contracts. Use sui-decompile to study existing contracts, then use sui-move to write your own.
• sui-coverage: Analyze test coverage. Decompile a contract, write tests for it, then check coverage.

Typical workflow:

1. sui-decompile - Study how a DeFi protocol works
2. sui-move - Write your own contract based on learned patterns
3. sui-coverage - Ensure your code is well-tested

Server/Headless Setup

For running on servers without display (CI/CD, VPS, etc.), use Puppeteer with a virtual display to avoid headless detection:

# Install xvfb (virtual framebuffer)
sudo apt-get install xvfb

# Run with virtual display (avoids headless detection)
xvfb-run --auto-servernum node scraper.js

Puppeteer example:

const puppeteer = require('puppeteer');
