🔥 The Problem

Gas fees are unpredictable. You want to:

• Swap tokens → but ETH gas is 45 Gwei
• Mint an NFT → but you don’t know if Polygon is cheaper
• Bridge funds → but you’re guessing the optimal chain

MiMoGas solves this in 3 seconds.

✨ Features

📊 Real-Time Gas Dashboard

• 15 EVM chains in one view — Ethereum, BNB, Polygon, Arbitrum, Optimism, Base, Avalanche, Gnosis, Fantom, Celo, zkSync Era, Linea, Scroll, Mantle, Polygon zkEVM
• Live gas prices fetched from Blockscout V2 API (free, no API key)
• ETH transfer cost calculator per chain
• Visual gas intensity bars (green = cheap, yellow = moderate, red = expensive)

🧠 MiMo AI Gas Advisor

• Xiaomi MiMo V2.5 analyzes real-time data and generates actionable advice
• “Best Now” / “Good Choice” / “Wait” recommendations
• Specific savings percentages (e.g., “Save 98% vs Ethereum”)
• Timing advice based on historical patterns

📊 Gas Price Ranking

• All chains ranked from cheapest to most expensive
• Visual comparison bars for instant understanding
• Filter by: Cheap (<1 Gwei) / Moderate / Expensive (>10 Gwei) / L2 only

🔄 Auto-Refresh

• Data refreshes every 60 seconds
• Always up-to-date for time-sensitive decisions

🎬 How It Works

1. Open the page → 15 chains load simultaneously
2. See gas prices → ranked, compared, visualized
3. Read AI advice → MiMo tells you where to transact now
4. Filter & compare → find the cheapest chain for your needs

That’s the entire UX.
