The problem AVASense 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.

Challenges I 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.
