Vault AI

This project is an AI-powered DeFi super app designed to simplify crypto investing, trading, and lending while providing on-chain credit scoring for flash loans. The platform acts as an intelligent crypto assistant, helping users make informed decisions on swaps, staking, lending, and borrowing, all while ensuring seamless onboarding with social login and Privy-powered wallets.

Users can query real-time DeFi data, including top trending coins, best-performing liquidity pools, validator rankings, and market insights. The AI engine analyzes on-chain and off-chain data to recommend profitable DeFi strategies, helping users maximize returns with minimal effort. The platform also enables one-click crypto purchases (onramp) and gasless transactions for an intuitive and beginner-friendly experience.

One of the core innovations is on-chain credit scoring, which evaluates a user’s transaction history, wallet activity, and reputation to determine eligibility for flash loans. This unlocks capital-efficient borrowing without requiring collateral, making DeFi lending more accessible.

The goal is to abstract away the complexity of DeFi, allowing both beginners and advanced users to effortlessly manage their crypto portfolios. Whether you want to swap tokens, stake assets, participate in yield farming, or take a flash loan, the AI-powered agent handles everything for you—securely and efficiently.

Key Features: 🔹 AI Crypto Assistant – Ask questions about trending coins, pools, validators, and market movements. 🔹 Smart Trading & Staking – AI suggests and executes swaps, staking, and yield farming strategies. 🔹 On-Chain Credit Score – Wallet-based reputation system for flash loans and DeFi borrowing. 🔹 Onramp & Wallet Abstraction – Buy crypto easily and get a Privy-powered wallet via social login. 🔹 DeFi Dashboard – Track portfolio performance, APYs, and market trends in one place. 🔹 Gasless & Automated Transactions – No need to worry about gas fees; everything is streamlined. 🔹 Multi-Chain & Cross-Chain Support – Interact with Ethereum, Solana, Layer 2s, and more seamlessly.

This project is built using Next.js, TypeScript, and TailwindCSS, providing a fast, scalable, and highly responsive frontend. The core functionality revolves around an AI-powered DeFi agent, which is powered by LangChain and LangGraphs to handle complex user queries, execute actions like swaps, staking, lending, and provide real-time market insights.

For user onboarding, we integrated Privy, enabling users to log in using social accounts (Google, Twitter, etc.) and automatically create a self-custodial wallet. This removes the friction of traditional Web3 onboarding, making the platform accessible to both beginners and experienced users.

To fetch real-time blockchain data, we utilize multiple APIs, including:

DeFi protocols for token prices, liquidity pools, and staking APYs. Validator APIs to rank and provide insights into staking opportunities. Flash loan and lending APIs to check interest rates and eligibility based on on-chain credit scores. For wallet interactions and on-chain execution, we use Coinbase OnchainKit, which simplifies smart contract interactions, transaction batching, and account abstraction. This allows users to swap, stake, and borrow seamlessly, even covering gas fees where possible.

One of the hacky yet innovative things we did was integrating an on-chain credit scoring model that evaluates transaction history, wallet activity, and DeFi interactions to determine a user’s creditworthiness for flash loans and undercollateralized borrowing. This adds a trust layer to DeFi lending, making it more accessible and capital-efficient.
