How DeFi Works

Course info

Most people use DeFi through interfaces - pools, swaps, dashboards - without ever seeing the system underneath. When things work, that’s fine. When they don’t, it’s confusing. And confusion is where most bad decisions start.

This course shows you what DeFi actually is, beneath the apps and features. Not as hype, not as “the future of finance,” but as a coordination system: who participates, how value moves, and why incentives exist in the first place.

You’ll learn how automated markets replace counterparties, how different roles interact, where power actually lives, and how risk appears - not as an event, but as a structural property of the system.

Skip this course, and DeFi stays a collection of tools.
Take it, and DeFi becomes a system you can reason about.

What You’ll Learn (to see the system clearly):

  • What DeFi is - and what it isn’t - beyond interfaces and slogans
  • The roles inside DeFi and how they interact
  • How automated markets work without buyers and sellers matching directly
  • The difference between protocols and platforms - and why it matters
  • How value flows through the system, and where risk quietly accumulates

What you gain isn’t confidence - it’s orientation. You stop guessing how things fit together.
