Challenges we ran into

Natural Language Processing: We tried different models but had issues, so we switched to GPT, which worked well after a lot of testing.

Rust Smart Contracts: We didn't use a common template because our frontend was in Next.js, which has its own challenges with Rust. We worked to fix these issues.

Frontend in Next.js: Integrating wallets like Polkadot and Talisman was tough. We had to solve many problems to get wallet connections working in Next.js.

Gear Integration: Adding Gear to our frontend took a lot of time and effort, but it was necessary for our app to function correctly.
