DeFi in plain language

Decentralized finance (DeFi) refers to financial services — lending, swapping, staking, liquidity provision — built on public blockchains using smart contracts instead of traditional intermediaries.

Users typically interact through wallet-connected apps. Transactions are visible on-chain, but code bugs, oracle failures, and governance changes can cause losses.

Common DeFi building blocks

Automated market makers (AMMs) pool assets for swapping. Lending protocols let users deposit collateral and borrow against it. Yield farming and staking integrations add reward layers on top.

Yield comes with risk: impermanent loss, liquidation, protocol exploits, and token devaluation are all documented failure modes.

Before you connect a wallet

Read what permissions you grant. Revoke unused token approvals periodically. Start with amounts you can afford to lose while learning.

Official docs and audit reports help — but audits are not guarantees. Treat every new protocol as experimental until you understand its mechanics.
