The journey wasn't exactly smooth sailing. Here are the main hurdles we faced:
Gas Limits on Mainnet: The biggest headache came when trying to deploy to mainnet. Stylus is still under development, and we hit some gas limit issues that weren't apparent during local testing. We had to pivot to testnet deployment to keep development moving forward. The issue was with the amount of gas required being substantially higher than the required for deployment, $150 worth of ETH compared to $1.5.
Complex State Management: Building a system that handles user shares, multiple asset types, and maintains the right allocation ratios was tricky. We had to be super careful with the math to ensure users always get their fair share during withdrawals.
Protocol Integration: Since we were working on testnet, we couldn't just plug into existing DeFi protocols. We had to create our own test versions of swap pools and lending protocols to simulate the full functionality. This meant extra development work to create these mock contracts.
Risk Management: Designing the allocation strategy wasn't just about writing code - it required careful thought about risk profiles and how to balance potential returns with stability. We ended up using AI agents to help generate optimal distributions, which was an interesting solution to a complex problem.

5. Testing Edge Cases: The rebalancing function was particularly challenging to get right. We had to account for scenarios like partial fills, failed swaps, and making sure the contract always maintains the target allocation ratios even when dealing with leftover ETH.
   These challenges pushed us to think creatively and ultimately led to a more robust solution, even if it meant making some compromises along the way.
