About

The problem it solves Managing smart contract wallets can be intimidating and complex, especially for users unfamiliar with blockchain technology. Traditional wallet apps often lack user-friendly interfaces, require manual token transfers, and offer little protection in case of private key loss. 💡 **What Can People Use It For?** AVASense simplifies wallet management through an AI-powered assistant and smart recovery features: 🔐 **AI-Assisted Wallet Operations** Users can interact via voice or chat to: - Ask Any Queries - Send tokens - Check balances - Check Coin Prices 🚀 **Quick Setup of Smart Wallets** Automatically creates or retrieves a user’s smart contract wallet with a single connection. 🧬 **Enhanced Security via Guardians** Add trusted guardians who can help recover the wallet if access is lost. 💬 **Natural Language Interface** Use simple, human-friendly commands instead of complex wallet interfaces. ✅ **How It Makes Things Easier & Safer** - Reduces reliance on manual operations. - Makes crypto wallet interactions feel like a conversation. - Protects users from permanent loss with a secure recovery system. - Bridges the gap between AI and DeFi in a practical, accessible way. ## ✨ Features ### 🔐 Smart Contract Wallet * Automatically creates a non-custodial smart wallet for users on the Avalanche Fuji C-Chain. * Ensures on-chain execution of token transfers and account recovery flows. ### 🤖 AI Chat/Voice Assistant * Integrated AI assistant lets users interact via **text or voice** to perform actions like checking balances, sending tokens, or initiating account recovery. * Built for accessibility and convenience, especially for new users. ### 👛 Token Transfer * Send any ERC-20 token supported by the wallet through a secure and verifiable smart contract method. * Token parsing is AI-assisted for ease of use. ### 📊 Real-time Wallet Dashboard * Visualize balances and token holdings. * Automatically fetches token balances from the blockchain and displays them cleanly. ### 🛡️ Guardian-Based Recovery System * Add or remove **guardians** for account recovery. * Initiate, confirm, and execute recovery flows. ### ⚙️ Settings Interface * Manage wallet settings such as guardians or view smart wallet address. * Allows fine-tuned control for power users. ### 🌐 Cross-Wallet Support * Built with **RainbowKit + Wagmi**, supporting **Core Wallet**, MetaMask, WalletConnect, and etc. ### 🚀 Deployed on Avalanche * Uses the **Fuji Testnet (C-Chain)** for fast, secure, and low-cost transactions.

How it's made

Challenges we ran into ## 🧱 Challenges I Ran Into Building **AVASense** involved integrating multiple complex technologies, and we encountered several key challenges: ### 🔌 1. **Wagmi & RainbowKit Compatibility Issues** While trying to configure getDefaultConfig() from RainbowKit, we encountered breaking changes and API mismatches due to version updates. **Solution:** We reviewed the latest docs, removed deprecated methods, and manually configured chains and providers using custom Wagmi + RainbowKit setup. ### 🧠 2. **Initializing Wallet Signer Properly** The signer was not initializing correctly from ethers.js, causing runtime errors like Signer not initialized. **Solution:** We refactored the logic to pass the signer from useWalletClient() in Wagmi, ensuring consistent signer access. ### 🔁 3. **Network Switching Between C-Chain IDs** Sometimes, wallets were connected to Avalanche Mainnet (43114) instead of Fuji Testnet (43113), triggering errors like network changed. **Solution:** We implemented a robust wallet_switchEthereumChain fallback to prompt network switch and added logic to handle unrecognized chain errors. ### 🔐 4. **Smart Wallet Deployment & Retrieval** Handling new wallet creation and detection based on user address was tricky, especially when the factory contract returned the zero address. **Solution:** We added conditional logic to check for an existing wallet, create one if needed, and wait for confirmation before interacting with it.
