ArbiAgent is an AI-powered DeFi yield vault built on Arbitrum that helps users optimize their USDC allocation based on risk and market conditions. The platform combines an AI decision engine with smart-contract enforced rules, allowing the agent to analyze yield opportunities and recommend portfolio allocations while keeping fund execution under user authorization and on-chain constraints.

The current version integrates with Aave V3 and focuses on dynamic risk-based allocation. Our roadmap extends this architecture into a multi-protocol yield allocator that can compare protocols such as Aave and Morpho and automatically rebalance the vault's capital toward the most attractive risk-adjusted opportunities, while maintaining liquidity reserves and individual user ownership through vault shares.

During the hackathon, we simplified and strengthened the architecture of ArbiAgent. Initially, the project was designed around three separate risk modes — Conservative, Moderate and Aggressive. We decided to focus the current deployment on the Moderate strategy, implementing it as an independent vault with its own exposure limit and rebalance cooldown. The Conservative and Aggressive vaults remain planned as independent deployments.

We also moved from static/mock data toward a connected backend architecture. The frontend now communicates with our FastAPI backend and AI decision engine, which processes the vault and market data to generate allocation decisions. These decisions are signed using EIP-712 and verified by the smart contract before execution.

During the hackathon we also validated the complete flow on Arbitrum Sepolia: users can deposit USDC, receive ERC-4626 vault shares, execute an AI-generated rebalance into Aave V3, and withdraw funds with automatic liquidity recovery when capital is deployed.

The result is a functional end-to-end prototype that establishes the foundation for the next stage: expanding from a single Aave strategy into AI-driven multi-protocol yield allocation.

Bootstrapped / Pre-funding. ArbiAgent has not raised external funding yet. The project won 1st place in the General category at the ETH Lima Hackathon 2026, validating the technical execution and product direction. The prototype was built and deployed on Arbitrum Sepolia, with real on-chain transactions and Aave V3 integration. We are now seeking funding to continue development toward mainnet, multi-protocol yield allocation, security audits, and autonomous rebalancing.
