DeFi (Decentralized Finance) means financial services without banks, brokers, or intermediaries. Instead, smart contracts on blockchains handle everything automatically.
What can you do with DeFi?
Swap tokens
Exchange one crypto for another without an exchange. Platforms: Uniswap, Jupiter, Curve.
Similar to using an exchange, but you keep custody of your funds.
Lend and borrow
Deposit crypto to earn interest, or borrow against your holdings. Platforms: Aave, Compound, Morpho.
Typical lending yields: 2-8% APY depending on the asset.
Provide liquidity
Supply pairs of tokens to decentralized exchanges and earn trading fees. This is how DEXs work — they use your deposited tokens to facilitate trades.
Warning: Providing liquidity comes with impermanent loss risk. Use our Impermanent Loss Calculator to understand the risk before depositing.
Stake
Lock up tokens to help secure a network and earn rewards. Use our Staking Calculator to estimate returns.
DeFi vs Traditional Finance
| Feature | DeFi | Traditional Finance |
|---|---|---|
| Availability | 24/7/365 | Business hours |
| Access | Anyone with a wallet | Requires KYC, credit checks |

| Regulation | Limited | Heavy |
| Insurance | Usually none | FDIC/SIPC protected |
The real risks of DeFi
Smart contract risk
The code could have bugs. Even audited contracts can be exploited. In 2025, DeFi hacks caused over $1 billion in losses.
Impermanent loss
When you provide liquidity, price changes can cause you to end up with less value than if you'd just held the tokens. Use our IL Calculator.
Rug pulls
Malicious developers can drain liquidity from a DeFi protocol. Check our Risk Scanner before interacting with any protocol.
User error
DeFi has no customer support. Wrong transaction? Wrong contract? Gone forever.
Should beginners use DeFi?
Honestly: not yet. Master the basics first:
- Understand crypto wallets
- Get comfortable with basic transactions
- Understand gas fees
- Learn to read what you're signing
When you're ready, start with simple staking on established protocols (Aave, Lido) with small amounts.
