Decentralized finance lets you earn yield, lend assets, and trade without a bank. But the complexity and risk are real. These guides break down every major DeFi concept from first principles.
From understanding what DeFi is to managing the risks of advanced yield strategies — these guides build in sequence.
Decentralized finance explained from scratch. Smart contracts, on-chain protocols, self-custody, and how DeFi differs from CeFi platforms like Coinbase or Binance.
How proof-of-stake staking works, what APR you can realistically expect, the difference between native staking and liquid staking, and where the yield actually comes from.
How AMM liquidity pools work on DEXs like Uniswap and Aerodrome. What LP tokens represent, how fees are earned, and the mechanics of impermanent loss.
Moving liquidity across DeFi protocols to maximize yield. Strategies, the compounding math, the risks of chasing APY, and why most retail yield farmers underperform.
How Aave, Compound, and other lending protocols work. Supplying assets to earn interest, borrowing against collateral, liquidation thresholds, and health factor management.
Smart contract exploits, rug pulls, impermanent loss, oracle manipulation, liquidation cascades, and regulatory risk — every major DeFi risk category explained with real examples.
Centralized exchanges vary widely in their DeFi and staking offerings. Here's how the three Brian recommends compare.
| Feature | BTCC | Bitunix | MEXC |
|---|---|---|---|
| On-Exchange Staking | No | No | Yes |
| Yield / Savings Products | No | No | Yes — MEXC Earn |
| New Token / DeFi Launches | No | Limited | Yes — Kickstarter |
| Futures / Leverage Trading | Yes — 150× | Yes — 200× | Yes — 200× |
| Copy Trading | Yes | Yes | Yes |
| US Access | US-Friendly ✓ | Check availability | Check availability |
| Get Started | Open BTCC → | Open Bitunix → | Open MEXC → |
For on-chain DeFi (Aave, Uniswap, Lido, etc.) you will need a Web3 wallet such as MetaMask connected directly to the relevant blockchain. The exchanges above are centralized platforms — they do not provide access to on-chain DeFi protocols.
Common questions from people new to decentralized finance.
DeFi (Decentralized Finance) refers to financial services built on public blockchains — primarily Ethereum and competing chains — that operate through smart contracts rather than banks or brokerages. This includes lending, borrowing, trading, and earning yield without a central intermediary controlling your funds.
DeFi carries significant risks including smart contract bugs, protocol exploits, impermanent loss, liquidation, and rug pulls. Unlike bank deposits, DeFi funds are not insured. Understanding these risks before committing capital is essential — start with staking on established protocols before exploring higher-risk strategies. Read the DeFi Risks guide on this site before deploying any capital.
Staking involves locking a single token to help secure a proof-of-stake blockchain or earn protocol rewards — it is the simpler, lower-risk option with more predictable yields. Yield farming involves providing liquidity to DeFi protocols and moving capital between pools to maximize yield, which carries additional risks including impermanent loss and protocol risk.
DeFi yields vary enormously. Ethereum staking via Lido yields roughly 3–5% APR. Established lending protocols like Aave yield 2–8% on stablecoins. Liquidity pool farming can yield 10–50%+ but involves impermanent loss. Newer protocols advertising 100%+ APY typically carry extreme risk — the high yield compensates for that risk. Sustainable, low-risk yields are generally in the 3–10% range.
MEXC offers staking and yield products directly on the platform through MEXC Earn. Bitunix focuses primarily on futures and copy trading. BTCC is a futures-only exchange. For on-chain DeFi, you will need a Web3 wallet like MetaMask connected to protocols like Aave, Uniswap, or Lido — centralized exchanges do not provide direct access to these protocols.
