Decentralized finance (DeFi) explained

DeFi uses blockchain smart contracts to provide financial functions such as trading, lending and asset management.

How it works

Instead of relying entirely on a traditional intermediary, users interact with protocols whose rules are partly encoded in software. Governance and front-end operators can still have significant influence.

What to check

Check contract controls, collateral rules, oracle dependencies, governance and audits before treating a protocol as autonomous.

  • Check contract controls
  • Understand collateral and liquidation rules
  • Identify oracle and governance dependencies

Limits and risks

DeFi adds smart-contract, oracle, liquidation and governance risk on top of normal market risk. High yields often compensate for risks that are not obvious from the headline rate.
