DeFi (Decentralised Finance)

Financial services such as lending, trading and yield built on public blockchains via smart contracts instead of banks or brokers.

Definition

DeFi replaces intermediaries with smart contracts so users can lend, borrow, swap and earn yield directly from self-custodied wallets. It is permissionless and composable, meaning protocols plug into one another, which enables 'GambleFi' projects that blend betting with DeFi mechanics like liquidity pools and yield. DeFi carries substantial risks: smart-contract exploits, impermanent loss, scams and 'rug pulls', extreme volatility, and little or no consumer protection or recourse. Advertised yields are not guaranteed and often reflect high risk or unsustainable token emissions rather than safe returns.

Worked example

A GambleFi platform might let users deposit tokens into a liquidity pool that funds the 'house' side of bets, sharing in the casino's profits and its losses.

Why it matters

Explains the financial machinery behind newer crypto-gambling models; professionals must assess smart-contract, liquidity and regulatory risk.
