Decentralised Finance in Plain English"},"content":{"rendered":"<p>DeFi, short for decentralised finance, is a catch-all term for financial services built as open software on public blockchains. Instead of a bank or broker in the middle, smart contracts hold the rules, and anyone with a wallet can use them \u2014 no account application, no gatekeeper.<\/p>\n<h2>What you can do<\/h2>\n<ul>\n<li><strong>Trade<\/strong> tokens on decentralised exchanges that match users directly through liquidity pools.<\/li>\n<li><strong>Lend and borrow<\/strong> through protocols that let you earn interest on deposits or borrow against collateral.<\/li>\n<li><strong>Earn yield<\/strong> by providing liquidity or staking, though returns come with real risks.<\/li>\n<\/ul>\n<h2>Why it matters<\/h2>\n<p>DeFi is open and composable: applications can plug into one another like building blocks, and the code is public for anyone to inspect. That transparency and permissionless access are its biggest strengths \u2014 you do not need anyone&rsquo;s approval to participate.<\/p>\n<h2>The risks<\/h2>\n<p>Those same properties cut both ways. Smart-contract bugs can be exploited, and there is often no customer-support line or refund if something goes wrong. Prices can move fast, &#8220;yields&#8221; can be unsustainable, and some projects are outright scams. Self-custody also means you are responsible for your own keys and mistakes.<\/p>\n<p>Explore the DeFi tokens we track on our <a href=\"\/defi-tokens\/\">DeFi hub<\/a>.
