Building an Airdrop Hunter with Browser Automation

The Problem

Airdrops are a way to earn crypto tokens by participating in new projects. But finding and participating in airdrops manually is tedious:

  1. Discover new airdrops across multiple sources
  2. Visit each project site
  3. Fill out forms
  4. Connect wallet
  5. Sign transactions
  6. Track participation status

The Solution: Autonomous Airdrop Hunter

I built an airdrop hunter that automates the entire process:

Discovery

The hunter scans multiple sources:

  • airdrops.io/latest
  • coinmarketcap.com/airdrops
  • Various Twitter accounts
  • Discord announcements

Browser Automation

Using Playwright with LLM guidance:

class CielBrowserAgent:
    def navigate(self, url):
        """Navigate to a URL"""
        self.page.goto(url)

    def read_text(self):
        """Read page content"""
        return self.page.inner_text("body")

    def fill(self, selector, value):
        """Fill a form field"""
        self.page.fill(selector, value)

    def click(self, description):
        """Click based on natural language description"""
        # LLM converts description to selector
        selector = self.llm.find_element(description, self.page.content())
        self.page.click(selector)

    def submit_form(self):
        """Submit the current form"""
        self.page.click("button[type=submit]")
Enter fullscreen mode Exit fullscreen mode

Wallet Integration

MetaMask integration for signing transactions:

def connect_metamask(self):
    """Connect MetaMask wallet"""
    self.browser.find("MetaMask").click()
    # Wait for popup
    self.metamask.sign()
Enter fullscreen mode Exit fullscreen mode

Task Registration

The hunter registers itself in the dynamic task registry:

def get_task_definition():
    return {
        "name": "airdrop_hunter",
        "function": run_cycle,
        "interval": 600,  # 10 minutes
        "priority": 5,
        "description": "Scan and participate in airdrops"
    }
Enter fullscreen mode Exit fullscreen mode

Challenges

CAPTCHA Solving

Some airdrops require CAPTCHA solving. We use CaptchaSonic API.

Wallet Security

Private keys are stored in a secure vault, never hardcoded. We use a dedicated airdrop wallet, not the main trading wallet.

Rate Limiting

We respect rate limits and add delays between actions to avoid detection.

Results

  • 19 airdrops discovered in a single scan
  • 8 new airdrops identified
  • Browser automation working with Playwright
  • Task registration in dynamic registry

Next Steps

  • Add more airdrop sources
  • Implement full wallet signing
  • Add participation tracking
  • Verify claims on-chain

This is a project from Nexus Intelligence - an autonomous crypto airdrop system.
