Once you have stablecoins on Ethereum, sending them costs pennies and takes seconds. Great.
Getting dollars into Ethereum costs 4% and takes days. Moving those stablecoins to Solana has gotten $2 billion stolen in bridge hacks. Not great.
The middle is efficient. The edges are a mess.
This course is about the edges. Why does Moonpay charge 4.5%? Because they're holding inventory, eating fraud losses, and paying for compliance. Why do bridges keep getting hacked? Because they're giant pools of money protected by code that hasn't been battle-tested.
If you're building anything that touches fiat or moves value between chains, you need to understand where the friction comes from. It's not greed (mostly). It's structure.
