DeFi is an ecosystem of financial applications built on blockchain networks. Learn how smart contracts work, what opportunities they provide, and why more and more people are choosing decentralized finance over traditional banks.
What is DeFi?
Decentralized Finance (DeFi) is a collective term for financial products and services accessible to anyone who can use Ethereum — practically anyone with an internet connection. With DeFi, markets are always open and there are no centralized authorities that can block payments or deny access. Services that were previously slow and prone to human error are now automatic and more secure, as they are governed by code that anyone can inspect and verify.
How do smart contracts work?
Smart contracts are programs stored on the blockchain that execute automatically when predetermined conditions are met. They eliminate the need for intermediaries and ensure transparency of every transaction. Anyone can read the code of a smart contract and verify that it works exactly as promised. This is the foundation of trust in the DeFi ecosystem.
Advantages over traditional finance
DeFi offers numerous advantages: 24/7 accessibility, no geographic restrictions, full transparency through public code, lower fees compared to traditional financial institutions, and the potential for higher yields. Additionally, users maintain full control over their assets — there is no bank or institution that can freeze your funds.
