Follow the topic.
Not the hype.
From your first definition to the questions behind a complex position, choose a learning path with a clear purpose.
01
DEXs & liquidity
Read swap quotes, understand pool mechanics, and compare trading costs with the outcome you actually receive.
02DeFi lending
Separate supplying from borrowing. Work through collateral, health factors, and the repayment path.
03Staking
Compare direct operation, pooled participation, liquid receipts, and their different exit mechanics.
04Stablecoins
Look behind the price target at backing, redemption, token identity, and the applications using the asset.
05Yield farming
Follow the source of rewards. Distinguish APR, APY, token incentives, and net economic returns.
06Security & risk
Review wallet permissions, contracts, dependencies, and the things a checklist cannot guarantee.

Stablecoins in DeFi: Backing, Redemption, and Depeg Risk
Look beyond a stable price target to examine reserves, collateral, redemption access, network identity, and exit routes.
DEX Swaps Explained: Slippage, Price Impact, and Fees
Learn to read a swap quote, calculate minimum received, compare total costs, and distinguish slippage from price impact.
Staking vs. Liquid Staking: Rewards, Control, and Exits
Compare validator operation, pooled participation, receipt tokens, redemption, and the extra layers added by DeFi use.
Liquidity Pools and Impermanent Loss, With an Example
Work through a two-asset pool example and compare inventory changes, fee income, and the alternative of simply holding.
Yield Farming: APR vs. APY and the Cost of Compounding
Use worked calculations to separate simple rates, compounding assumptions, token incentives, and a strategy’s net outcome.
A better order of operations
Read. Question.
Then decide.
You do not need to rush into a transaction to understand one. Use the site as a learning library, not a list of things you are supposed to buy.
01 / BUILD THE BASICS
Name the moving parts.
Separate the network, wallet, token, contract, and interface. Learn what each component does before combining them into a strategy.
Understand DeFi02 / FOLLOW THE VALUE
Ask where returns come from.
Identify the activity behind a reward and distinguish token quantities from their economic value. Keep the assumptions in every calculation visible.
Read yield calculations03 / PLAN THE EXIT
Know what could change.
Trace permissions, dependencies, and withdrawal steps. An attractive entry is only one part of understanding the complete operation.

Follow the beginner pathWhat is DeFi?
DeFi is a category of financial applications that use blockchain-based programs to coordinate activities such as token exchange and collateralized lending. It is not one app or a guarantee of decentralization. Read our beginner’s guide to DeFi for the layers and their roles.
Is DefiFortune.com an exchange or investment service?
No. This is an educational publication. You cannot deposit funds, connect a wallet, buy assets, or execute trades here. The guides explain mechanics and questions to research; they do not determine which financial decisions are suitable for you.
Are stablecoins risk-free?
A stable price target is not a complete risk assessment. Backing, redemption, controls, network identity, and the application holding an asset all matter. Our stablecoin guide explains these questions without recommending an issuer or promising that a target price will hold.
Does a high APY mean a better return?
Not on its own. A yield estimate needs context about compounding, fees, asset prices, incentives, and the period measured. The APR and APY guide uses hypothetical calculations to show why a larger percentage is not a complete economic comparison.
Which guide should I read first?
Begin with what DeFi means, then read the wallet security guide before investigating swaps, lending, or bridging. The beginner path links these ideas in order. Learning the terminology and practicing a paper example do not require a token purchase or a wallet connection.
Where do the explanations come from?
Articles link to a relevant primary source and distinguish illustrative calculations from current product information. Read the editorial policy for our approach to sources, uncertainty, and corrections. Check the exact deployment’s current documentation before relying on a protocol parameter.
Understanding risk is part of understanding DeFi.
Digital assets and DeFi activities can result in substantial or total loss. These guides are educational, not personalized financial advice.
