IntentFi

Problem Statement

IntentFi - AI-Powered Cross-Chain Trading Intent Platform IntentFi is an innovative decentralized finance (DeFi) platform that revolutionizes automated trading by allowing users to express their trading strategies in natural language and have them executed automatically across multiple blockchain networks using Chainlink's Cross-Chain Interoperability Protocol (CCIP).Core Concept The platform bridges the gap between human trading intuition and automated execution by leveraging artificial intelligence to interpret user intentions and convert them into executable smart contracts. Users can simply describe what they want to do (e.g., "buy ETH when the price exceeds $3000" or "take profits if my portfolio gains 20%") and the system automatically creates and deploys the corresponding trading logic across multiple blockchains.Key FeaturesNatural Language ProcessingUsers communicate with the AI agent using everyday language through asi1.ai No need to understand complex smart contract programming Supports multiple intent types: price-based, time-based, and risk management strategies 2. AI-Powered Recommendation EngineIntegrates with Claude AI for intelligent market analysis Provides confidence scores and detailed reasoning for each recommendation Sophisticated fallback system ensures functionality even when external AI services are unavailable Real-time news sentiment analysis influences trading decisions 3. Cross-Chain Execution via Chainlink CCIPUtilizes Chainlink's Cross-Chain Interoperability Protocol for seamless multi-blockchain operations Enables secure message passing and token transfers between different networks Supports major networks including Ethereum, Polygon, Arbitrum, and Flow blockchain Automatic chain selection based on gas costs and liquidity optimization 4.
