DeFi, short for decentralized finance, is a financial system built on public blockchains (mainly Ethereum) that allows peer-to-peer financial services without relying on traditional banks or centralized intermediaries. It enables users to do many activities that banks support—like earning interest, borrowing, lending, buying insurance, trading assets—all powered by smart contracts that automatically execute transactions when conditions are met. Key features of DeFi:
- Open and accessible to anyone with an internet connection and a crypto wallet, without needing to open accounts or provide personal information.
- Peer-to-peer and pseudonymous transactions.
- Faster and often cheaper than traditional financial services.
- Transparent, since all transactions are recorded on the blockchain.
- DeFi applications (dApps) run decentralized protocols that automate financial operations.
DeFi aims to create a more open, fair, and global financial market by removing middlemen, reducing costs, and increasing access to financial products worldwide. Examples of DeFi services include decentralized lending platforms, exchanges, and stablecoins, all running on blockchain technology with smart contracts handling the logic and execution autonomously. In essence, DeFi recreates many traditional financial services in a decentralized digital form that is accessible globally 24/7, without the need for banks or brokers. It also embodies the vision of digital money from Bitcoin, expanded into a full- fledged alternative financial ecosystem. This makes DeFi a transformative innovation in the world of finance, promising more democratic access and efficiency compared to traditional systems. However, being relatively new, it also carries risks like technical bugs and security vulnerabilities.

With DeFi, people can earn interest, borrow, lend, trade assets, and more—automatically and transparently through smart contracts—without paperwork or central authority. It is open, pseudonymous, fast, and accessible globally with just an internet connection and a crypto wallet. DeFi aims to create fairer, more efficient financial markets by replacing centralized middlemen with decentralized applications on blockchain networks.
