Financial services built on blockchain technology, operating without traditional intermediaries.
Decentralized Finance (DeFi) is a blockchain-based ecosystem of financial services that operate without banks, brokers, or traditional intermediaries. DeFi platforms enable users to lend, borrow, trade, and earn yield through smart contracts instead of relying on centralized institutions.
DeFi makes financial services accessible, programmable, and globally available.
Core Principles of DeFi
Open access: Anyone with a crypto wallet can participate.
Transparency: All transactions are visible on-chain.
Non-custodial: Users maintain full control of their assets.
Programmability: Financial logic is encoded in smart contracts.
Interoperability: Protocols can integrate and build on each other.
Common DeFi Services
DEX trading: Swap tokens on decentralized exchanges.
Lending and borrowing: Earn interest or take collateralized loans.
Yield farming: Provide liquidity in exchange for rewards.
Staking: Secure networks and earn tokens.
Derivatives and synthetic assets: Trade price exposure without custody.
Stablecoins: Access on-chain dollar equivalents.
