Think of DeFi like a vending machine. A regular bank is a cashier — you need to talk to a person who follows the bank's rules. DeFi is the vending machine — put in your money, get your item, no cashier needed. The rules are built into the machine (the smart contract).
With a regular bank savings account, you earn maybe 0.1% per year. On Aave (a DeFi app), you can earn 3–8% per year just by depositing your crypto — no forms, no minimum balance, no waiting period.
✅ Correct Answer: B
DeFi borrowing is like a pawn shop. You bring in something valuable (your ETH), the shop lends you cash (stablecoins), and if you don't pay back, they keep your ETH. Except this pawn shop has no human — a smart contract handles everything automatically, 24/7.
You deposit $1,000 of ETH on Aave. You can borrow up to $750 of USDC (75% LTV ratio). Meanwhile, your deposited ETH also earns interest. You now have $750 in your wallet AND your ETH is working for you.
| Platform | Type | Key Feature | Risk Level |
|---|---|---|---|
| Aave | Lending/Borrowing | Flash loans, variable & stable rates | Low–Medium |
| Compound | Lending/Borrowing | Simple UI, earns COMP token rewards | Low–Medium |
| MakerDAO | Stablecoin (DAI) | Borrow DAI against ETH collateral | Medium |
✅ Correct Answer: B
A liquidity pool is like a community swimming pool. Everyone chips in money to keep it filled. When people use the pool (make trades), they pay a small fee. That fee gets split among everyone who contributed water (liquidity). The more you contributed, the more of the fee you earn.
You add $500 of ETH + $500 of USDC to Uniswap's pool. Every time someone trades ETH for USDC (or vice versa), they pay a 0.3% fee. You get a tiny slice of every trade — 24/7, automatically, no effort required.
| DEX | Best For | Fee | Special Feature |
|---|---|---|---|
| Uniswap v3 | Most token pairs | 0.05–1% | Concentrated liquidity ranges |
| Curve Finance | Stablecoins | 0.04% | Ultra-low slippage on stable pairs |
| Balancer | Multi-asset pools | 0.1–1% | Up to 8 tokens in one pool |
✅ Correct Answer: B
Yield farming is like a farmer who grows whatever crop pays the most that season. When corn is most profitable, they grow corn. When wheat pays more, they switch. DeFi farmers move their money between protocols to always chase the highest yield — sometimes earning in 3 different ways at once.
Step 1: Lend USDC on Aave → earn 4% APY. Step 2: Take the interest-bearing aUSDC and deposit it into Curve → earn trading fees (extra 2%). Step 3: Stake your Curve LP tokens to earn CRV token rewards (extra 5%). Total: potentially 11% APY stacked from one asset.
| Strategy | Effort | Typical APY | Risk |
|---|---|---|---|
| Simple stablecoin lending (Aave) | Low | 3–6% | Low |
| LP in stablecoin pool (Curve) | Low–Med | 5–12% | Low–Med |
| LP + staking rewards (farming) | Medium | 10–50%+ | Medium–High |
| Yearn Finance vaults (auto-compound) | Very Low | 8–20% | Medium |
✅ Correct Answer: B
Impermanent loss is like putting equal weight on both sides of a seesaw. If one side (ETH) suddenly gets much heavier (price rises), the seesaw tips. To keep balance, your share of ETH shrinks and your stablecoin share grows. You miss out on some of ETH's rise — that "missed gain" is your impermanent loss.
You add 1 ETH ($2,000) + $2,000 USDC to a pool. ETH rises to $4,000. Instead of your 1 ETH being worth $4,000, the pool now shows you hold ~0.71 ETH + $2,828 USDC = $5,656. If you'd just held: $6,000. The $344 difference is your impermanent loss. But you also earned trading fees during this time, which may partially cover it.
✅ Correct Answer: B
Stablecoin Lending: Deposit USDC or USDT on Aave. Earn 3–6% APY with minimal price risk. Great starting point — your principal stays stable.
Stablecoin LP: Add USDC + USDT to a Curve Finance pool. Earn trading fees (~4–8% APY). Very low impermanent loss risk since both tokens are pegged to $1.
ETH/Stablecoin LP + Farming: Provide ETH + USDC liquidity on Uniswap, then stake LP tokens for extra token rewards. Higher potential returns (10–30%+), but exposed to impermanent loss and market swings.
| Check | What to Look For | Why It Matters |
|---|---|---|
| ✅ Audit | Certified by CertiK, Trail of Bits, OpenZeppelin | Reduces smart contract bug risk |
| ✅ TVL Age | Protocol has been live 1+ year with stable TVL | Battle-tested means fewer unknown bugs |
| ✅ TVL Size | $100M+ total value locked | Larger TVL = more community trust |
| ✅ Anonymous Team? | Team is public and known OR has strong community | Reduces rug pull risk |
| ✅ APY Sanity | Avoid 1000%+ APY promises from new projects | Unsustainable yields are often scams |
| ✅ Bug Bounty | Protocol offers rewards for finding bugs | Shows commitment to security |
✅ Correct Answer: B — Start slow, learn the ropes, then scale up.
