🎯 How It Works

The extension connects directly to the HyperEVM RPC endpoint to fetch real-time gas prices and displays them in three tiers:

• 🚶 Normal: Current network gas price (base fee)
• 🏃 Fast: Base price + 25% premium for faster confirmation
• ⚡ Instant: Base price + 50% premium for immediate confirmation

USD costs are calculated using live HYPE token prices from CoinGecko API with smart caching to respect rate limits.

🔒 Privacy & Security

Minimal Permissions

• storage: Store gas price data locally
• alarms: Schedule background updates
• No tracking permissions: We don't collect any personal data

Privacy-First Design

• ✅ No user tracking or analytics
• ✅ No personal data collection
• ✅ Local data storage only
• ✅ Open source and auditable
• ✅ Minimal API calls with smart caching

Network Requests

The extension only makes requests to:

• https://rpc.hyperliquid.xyz/evm - HyperEVM RPC for gas prices
• https://api.coingecko.com/api/v3/simple/price - HYPE token price (cached for 60 seconds)

🏗️ Technical Details

Gas Price Calculation

// Formula for USD cost estimation
const gasLimit = 46000; // Standard ERC20 token transfer
const costInHype = (gasPriceGwei * gasLimit) / 1000000000;
const costInUsd = costInHype * hypePrice;

Caching Strategy

• Gas prices: Updated every 5 seconds via Chrome alarms
• HYPE price: Cached for 60 seconds to respect API limits
• Local storage: Persistent across browser sessions
