Hey HN, I'm a 22 year old solo dev. Over the last 8 months, I wrote 315k lines of code to build an on-chain index fund platform.
The stack is FastAPI, React, Celery, Postgres, and Redis running on AWS for $70/month.
The core engine works by:
Aggregating up to 5,000 user orders every 30 seconds.
Routing them across DEX protocols for execution.
Settling into a single Gnosis Safe transaction to cut gas costs by 80%.
A custom blockchain scanner watches the network every 3 seconds with Redis deduplication to detect incoming deposits.
I built this entirely solo because I wanted a verifiable alternative to trusting centralized exchanges with custody. I'm hanging out in the comments and would genuinely love for you to roast the architecture or give feedback!
