Decentralized finance recreates financial services — lending, borrowing, trading — using smart contracts instead of banks or brokerages as the intermediary.
The Mechanics
DeFi protocols run on self-executing smart contracts (predominantly on Ethereum and similar platforms) that automatically handle lending pools, decentralized trading, and other financial functions without a central company controlling the process. This permissionless structure means anyone with a crypto wallet can access these services directly — but it also means none of the traditional consumer protections (FDIC insurance, dispute resolution, fraud reversal) that regulated traditional finance provides apply here.
Because DeFi smart contracts are generally immutable and irreversible once deployed, and there's no central authority to appeal to if something goes wrong, checking a specific protocol's security audit history and total value locked (a rough proxy for how much capital other users trust it with) matters more here than in almost any traditional financial product.
Someone New to DeFi: Understand there's no FDIC-style protection or dispute resolution — a fundamentally different risk profile than traditional finance.
Someone Evaluating a Specific DeFi Protocol: Check its audit history and total value locked before committing meaningful funds.
Approach DeFi the Way
- Understand there's no FDIC-style protection here.
- Check a protocol's audit history before committing funds.
- Start with small amounts while learning the mechanics.
