Example

TradFi, CeFi, and DeFi in practice

A lending product at a bank, a crypto lender, and an on-chain lending protocol can all offer borrowing, but the enforcement and custody models differ completely.

Swap in your own product or market and the same tradfi, cefi, and DeFi logic should still hold; if it doesn't, you have found an assumption worth checking.

A tradfi, cefi, and DeFi example earns its place by changing what you would actually do next, not by sounding impressive.

RememberDecision rule: Classify the product by who holds assets and who enforces the rules.
