The problem CrossMind solves

.# 🌉 CrossMind – AI-Powered Cross-Chain DeFi Investing

CrossMind is an AI-powered, cross-chain, non-custodial DeFi investment platform that simplifies crypto investing for everyday users. It combines the intelligence of Zoya, an autonomous agent built on ElizaOS + AWS Bedrock, with secure, scalable onchain execution using Chainlink CCIP.

---

🎯 Problem

DeFi today is:

• Complex and fragmented across multiple chains and protocols
• High-risk, with poor UX and technical onboarding barriers
• Idle capital sits untouched due to fear and friction

---

💡 Solution

CrossMind solves this with:

• Zoya: An AI investment agent that chats with users in natural language, understands their goals, and generates personalized strategies
• Smart contracts: Non-custodial, audited vaults and execution modules
• Chainlink CCIP: To enable secure cross-chain investment and rebalancing
• AWS Bedrock (via ElizaOS): For AI inference, risk reasoning, and strategy simulation

---

🛠️ How It Works

1. User connects wallet and chats with Zoya (built with ElizaOS + AWS Bedrock)
2. Zoya analyzes:
   • User risk profile
   • Market conditions
   • Real-time yield sources
3. Zoya generates an optimal DeFi strategy (e.g., 40% Aave lending, 60% QuickSwap LP)
4. Smart contracts execute the strategy across chains using Chainlink CCIP
5. The user receives a transparent, trackable, yield-optimized portfolio

🧠 AI Agent Architecture (Zoya + ElizaOS + AWS Bedrock)

Zoya is built using:

• ElizaOS: Agent framework that enables tools, memory, and context persistence
• AWS Bedrock: Provides foundation models like Claude, Titan for reasoning
• Retrieval-Augmented Generation (RAG) and real-time APIs for onchain data lookup

Zoya Capabilities

• Understand user intents like: “invest $500 conservatively”
• Explain strategy options, tradeoffs, and risks
• Auto-adapt portfolios based on live yield/risk shifts

🧱 Onchain Smart Contract Stack

Deployed on Avalanche Fuji and Ethereum Sepolia, featuring:

• CrossMindVault: Strategy-based asset vault
• StrategyManager: Maps user profiles to yield protocols
• CrossChainExecutor: Executes instructions across chains using CCIP
• AdapterRegistry: Manages protocol-specific adapters (e.g., Aave, QuickSwap)

Challenges we ran into

🐞 Challenges I Ran Into

🤖 ElizaOS + AWS Bedrock Integration Issue

While building the Zoya AI agent, we ran into a critical issue integrating ElizaOS with AWS Bedrock. The Bedrock inference was not properly resolving through the ElizaOS agent orchestration layer, causing broken message flows and timeouts during prompt execution.

🛠️ How We Solved It

We identified the issue was related to Bedrock invocation compatibility within ElizaOS's hosted tooling. We raised a detailed issue on the official ElizaOS GitHub repository, and thanks to their quick support and collaborative debugging, the issue was resolved within the hackathon window.

✅ Outcome

Once resolved, Zoya was able to:

• Successfully route user input through ElizaOS
• Generate prompt completions via AWS Bedrock models like Claude
• Return real-time strategy suggestions seamlessly

This enabled us to deliver a fully functional AI + Web3 integration and deploy a working version of CrossMind end-to-end.
