What Is DeFi?
Decentralized Finance (DeFi) recreates financial services — lending, trading, borrowing, earning interest — using smart contracts on a blockchain instead of banks or brokers.
Anyone with a wallet can use these services permissionlessly, with no account approval and no intermediary holding the funds.
Smart Contracts as the Backbone
Every DeFi protocol is built from smart contracts: self-executing code deployed on-chain. The contract holds the rules and often the funds.
Because the logic is transparent and runs deterministically, users can audit exactly how a protocol behaves before trusting it.
