The problem Crosschain Donation solves

CrossChainDonate makes decentralized fundraising accessible, transparent, and cross-chain ready.

Why it matters:
Most donation platforms are centralized and lack transparency.

Blockchain donations can be intimidating, especially for non-technical users.

Sending funds across chains (e.g., from Ethereum to Avalanche) is usually complex, involving multiple bridges or risky steps.

What people can use it for:
✅ Simple, transparent donation platform on Avalanche
✅ Donate in native AVAX or send funds cross-chain via Chainlink CCIP
✅ AI-powered assistant helps users understand the donation process in plain English
✅ Real-time donation history increases trust
✅ Supports causes like Education, Health, and Environment

In short:
CrossChainDonate simplifies blockchain philanthropy — safer, beginner-friendly, and cross-chain compatible.

Challenges I ran into

✅ Challenges I ran into
This project involved combining multiple advanced Web3 technologies under tight hackathon timelines:

Key challenges:
🚧 Cross-Chain Complexity:
Setting up Chainlink CCIP, configuring supported networks, and ensuring tokens safely moved between Sepolia and Avalanche Fuji took significant time. Documentation helped, but testing cross-chain flows was non-trivial.

🚧 AI Agent Integration:
ElizaOS was new, and configuring a custom AI persona, running the AI agent locally, and exposing it to the frontend required trial and error.

🚧 Frontend & Backend Coordination:
Keeping smart contracts modular (separating Donation logic from CCIP receiver) while ensuring seamless user experience meant extra coordination between contracts and the frontend.

How we overcame it:
Leveraged Chainlink's CCIP starter kits and faucet tools

Customized ElizaOS character to align with donation use-case

Modularized contracts to keep CCIP logic cleanly separated

Iterative testing across Sepolia and Avalanche

Styled the frontend to make the experience approachable for all users
