finally understand what an AMM is

I'd read about a hundred threads on DeFi and understood none of it. Building a liquidity pool in Python and watching slippage actually happen made it obvious in one lesson. The whale lesson right after is even better.

No wallets, no real money, no hype. Just how it actually works.

Dense. I had to redo the lending and liquidation lessons twice before it stuck. Worth it, but this isn't a casual one.

the yield question

The thing that stayed with me is the course keeps asking who is actually paying for the yield. Once you start asking that, a lot of crypto looks pretty different.
