TradFi is short for “traditional finance.” It refers to the conventional financial system—institutions and structures that existed before the rise of crypto and decentralized finance (DeFi).

That includes things like:

Banks (retail and investment)

Stock exchanges

Asset managers and hedge funds

Central banks

Insurance companies

In contrast to DeFi, TradFi is typically:

Centralized (controlled by institutions)

Regulated by governments

Intermediary-based (you need banks, brokers, etc. to transact)

People often use “TradFi” when comparing it to crypto/DeFi, especially in discussions about:

Regulation vs decentralization

Trust in institutions vs trustless systems

Speed and cost of transactions
