VoxSol

Elevator Pitch

Talk to your Solana wallet. Voice-powered DeFi with Gemini AI and real on-chain swaps.

Inspiration

Managing a crypto wallet shouldn't require staring at complex interfaces. I wanted to create something that felt as natural as asking Siri or Alexa for help - but for Solana DeFi. What if you could just say "swap 0.5 USDC to SOL" and have it happen?

What it does

VoxSol is a voice-first Solana wallet copilot. You can:

• Check your portfolio balance by speaking
• Execute real token swaps on Solana devnet
• View live price charts
• Get AI-powered responses that understand DeFi context

Everything is non-custodial - you connect your own wallet and sign every transaction yourself.

How I built it

• Frontend: Next.js 14 with Tailwind CSS for a sleek, dark-themed UI
• AI Chat: Gemini API processes natural language and understands DeFi commands
• Voice Input: Web Speech API for speech-to-text
• Voice Output: ElevenLabs API for natural text-to-speech responses
• Blockchain: Solana devnet with @solana/web3.js for real on-chain transactions
• Wallet: Phantom, Solflare, Backpack integration via wallet adapter
• Swap Execution: Custom vault that handles USDC ↔ SOL swaps at market rates

What I learned

• How to integrate voice interfaces with Web3 applications
• Building AI agents that understand financial context
• Working with Solana transactions and token transfers

What's next

• AI Agent Allowance: Set spending limits for autonomous trading
• Yield Vaults: One-click deposits into yield strategies
• Mainnet deployment with Jupiter integration
