DeFi, short for decentralised finance, is a set of financial services such as trading, lending and borrowing that run on public blockchains through smart contracts, instead of through a bank or a company's systems.

How it works

People connect a self-custody wallet to a DeFi app and interact directly with smart contracts. A decentralised exchange, for example, lets users swap one token for another from a shared pool of funds, with prices set by code rather than an order book run by a company.

Centralised (CeFi)

a company holds your funds, checks your identity and handles support.

DeFi

you keep control of your wallet and deal with code; there's usually no one to call if something goes wrong.

The risks

Bugs in smart contracts have led to large losses, prices can move very fast, and some projects are outright scams. Transactions generally can't be reversed, and in the UK crypto isn't covered by the Financial Services Compensation Scheme.
