Prompt2Loan

Prompt2Loan is an AI-native, cross-chain DeFi platform that enables users to obtain crypto-backed loans and move liquidity seamlessly across chains, powered by AAVE v3, Li.Fi, and intelligent agents. The platform is designed for production use, combining institutional-grade architecture with a clean, mobile-first user experience.

Prompt2Loan follows a modular Web3 architecture optimized for scalability and security.

Base: Primary execution layer for lending, borrowing, and payments. AAVE v3: Core liquidity and lending protocol. Li.Fi: Cross-chain routing, quoting, and execution. AI Agent Layer: Decision support, automation, and UX abstraction.

AI Agent (LangChain + LangGraph): Prompt2Loan includes a transaction-native AI Agent built with LangChain and LangGraph, designed to convert natural language intent into safe, executable DeFi transactions.

The agent never signs or broadcasts transactions. Instead, it prepares validated transaction payloads that are returned to the frontend for explicit user approval.

Agent Overview

• LLM: LLaMA 3.1 (AWS Bedrock)
• Framework: LangChain + LangGraph
• Memory: Thread-based session memory
• Execution Model: Tool-only responses

• Borrow USDC

Swaps & Cross-Chain Transfers (Li.Fi)

• Token swaps on Base
• Bridging to supported L1s and L2s
• Optional destination address
• Automatic ERC-20 allowance checks
