Start here. Build the basics.

Step 1: Understand what you are looking at

Begin by separating the network, wallet, asset, contract, and interface. A single application screen can make these components look like one product, but each has a different job. Read What is DeFi? and describe an imaginary transaction in your own words before moving on.

Your first learning goal is simple: explain what is sent, what is received, and which rules determine the result. A phrase such as “earn yield” is not yet a complete explanation. Keep a notebook of definitions and questions you cannot answer.

Step 2: Learn authority before activity

Read the wallet security guide. Distinguish an address, a recovery credential, a website connection, a signature, and a token approval. These concepts are easier to examine calmly than when a transaction is waiting for confirmation.

Do not share private keys or recovery phrases. This site never needs them, and no guide here requires a wallet connection. Use the security hub to extend the review from your wallet to the application requesting authority.

Step 3: Pick one mechanism

Choose exchanges and liquidity, lending, staking, or stablecoins. Read its core explanation before comparing individual providers. Write a one-sentence description of what the activity does without using promotional words such as effortless or guaranteed.

A useful explanation names the asset, the source of any reward, and the exit. When several mechanisms are combined, draw them separately first. Understanding one layer is not proof that every layer built on top of it behaves similarly.

Step 4: Work through a paper example

Use the guide’s hypothetical numbers, then change one assumption. Try a different fee, asset price, debt balance, or compounding period. Notice which parts of the result change. The yield guide and lending example make their assumptions explicit so the arithmetic can be checked.

Paper examples are learning tools, not forecasts. A current quote, contract parameter, or redemption term must be verified separately for an actual deployment.

Step 5: Describe how the position ends

Work backward from the asset you would want at the end. Identify withdrawals, conversions, repayments, and any waiting period. Ask whether the normal exit is also available under stress. An operation that is easy to enter is not necessarily easy to reverse.

Use the DeFi risk checklist to organize evidence and unknowns. A decision not to proceed is a valid result of research. This educational site cannot determine a suitable financial action for your circumstances.
