9. What are staking, stablecoins, lending, and DeFi?

2–3 minute lesson · Fictional practice · New York / U.S. · Reviewed October 26, 2026

What is it?

These are different activities. A stablecoin aims to track a reference value; it is not automatically an insured deposit. Staking supports certain networks, while lending puts assets into a credit arrangement. A wallet can display access to a third-party product without the wallet itself paying or guaranteeing interest. DeFi protocols such as Aave and Morpho have market-specific terms and risks. Access to an interface is not proof that a product is permitted for a New York resident.

Why care?

To know what creates a return and what can be lost.

When would I use it?

Before enabling earn, supply, borrow, collateral, or a token approval.

Worked example

Fictional debt is $500 against collateral worth $1,000: LTV is 50%. If collateral falls to $625 with debt unchanged, LTV becomes 80%. A product's own liquidation rules determine what happens; these figures are not a safe borrowing recommendation.

How to practice

Identify the actual protocol, asset, chain, rate source, fees, liquidity, collateral rules, and location terms. Compare APR with APY and distinguish a variable quote from a guarantee.

The result to aim for

You can explain the risk behind a yield and recognize liquidation exposure.

One useful step now: Understanding the vocabulary now does not require depositing or borrowing.
