GhostPay AI 👻

GhostPay AI is an invisible Web3 gasless payments and AI assistant platform. It allows users to perform blockchain transactions using conversational AI, abstracting away the complexity of RPCs, wallet signatures, and gas fees. Powered by the Universal Gas Fund (UGF), all gas fees are covered automatically, making Web3 completely gasless and seamless.

✨ Key Features

• 🤖 AI Transactions: Command your wallet in plain English. Our AI translates natural language prompts into secure blockchain calls (e.g., "Donate 5 USD" or "Transfer 10 USDC to vitalik.eth").
• ⛽ Gasless Payments: Say goodbye to native chain gas tokens. The Universal Gas Fund (UGF) handles 100% of network fees seamlessly via meta-transactions.
• 🏅 NFT Badge Minting: Mint achievement certificates, event logs, and participation badges gaslessly.
• 📊 Activity Dashboard: Review historic AI executions, sponsored gas credits, pending transactions, and an address book directory.
• 👁️ Smart Transaction Preview: See a transparent, human-readable cost breakdown and exact transaction details before confirming.
• 🔗 Cross-Chain Routing: Deploy transactions across Ethereum, Polygon, Arbitrum, and Base without switching networks in your wallet.
