DeFi, short for decentralized finance, refers to a set of financial applications built on blockchains that aim to recreate services like lending, borrowing, and trading without relying on a traditional bank or broker in the middle. Instead, these services run on smart contracts, which are self-executing pieces of code that enforce the rules automatically.
For example, in a DeFi lending protocol, you might deposit cryptocurrency into a smart contract and earn interest, while someone else borrows against collateral they have deposited, all without either party needing to apply through a bank.
DeFi has grown quickly because it can operate continuously, across borders, without requiring approval from a central institution. At the same time, it carries real risks, including bugs in the smart contract code and the lack of a safety net like deposit insurance if something goes wrong.
Frequently Asked Questions
Is DeFi safer than a traditional bank?
Not necessarily. DeFi removes certain middlemen, but it introduces different risks, such as smart contract bugs and the absence of deposit insurance, so "different" is more accurate than simply "safer."
Do I need to know how to code to use DeFi?
No. Most DeFi applications have a regular website interface, similar to online banking, although understanding the basic risks before depositing funds is strongly recommended.
