Solution

We built Pooleth using Next.js 15, React 18, and TypeScript with OpenAI's Realtime API for natural voice interactions.Privy handles wallet authentication and embedded wallets, while Ledger integration via Ledger DMK allows to securely store funds for long term storage directly through voice command.The Adamik API gives us unified blockchain access across 10+ EVM chains without managing multiple RPCs.Circle's CCTP enables seamless USDC bridging between networks.We used a multi-agent architecture which includes:Pooleth Agent: Voice interface and intent recognitionSupervisor Agent: Blockchain operation execution, connection to Privy and LedgerTreasury Manager: Portfolio analysis and strategic recommendationNotable technical achievements:Voice-to-blockchain pipeline converting natural language to DeFi operationsSingle address working across all EVM chainsReal-time multi-chain portfolio aggregationSeamless AI recommendations to executable transactionsPrivy signature approval and Ledger device getAddress and signEthereumTransactionHacky parts & limitations (hackathon reality!):Yield rates for lending pools are currently mocked.CCTP bridging works smoothly but Privy's transaction modal doesn't display bridge-specific details (amount, source/destination chains) - ideally needs a custom bridge confirmation UIThis approach still lets users manage complex DeFi operations through simple voice commands, making crypto portfolio management as easy as having a conversation.
