10 carefully crafted crypto modules. Each topic includes Learn, Flashcard, and Quiz modes to build lasting Web3 knowledge.
What is Bitcoin: Digital Gold Explained
Bitcoin is the first decentralized cryptocurrency with a fixed supply of 21 million. Like digital gold — scarce, transferable, and censorship-resistant.
What is a Stablecoin: USDT/USDC Explained
Stablecoins are cryptocurrencies pegged to a fiat currency (usually $1 USD). They're the "cash" of crypto — used to avoid volatility, transfer funds cross-chain, and participate in DeFi.
What is DeFi: Decentralized Finance Explained
DeFi (Decentralized Finance) is a financial system without banks — lending, trading, and earning yield through smart contracts. Code is the rule, not institutions.
Gas Fees Explained: Blockchain Transaction Costs
Gas fees are the cost to execute operations on a blockchain — like fuel for transactions. Ethereum mainnet gas is expensive; Layer2 networks cut costs by 90%+.
What is Staking: Earning Yield on Crypto
Staking locks crypto in a network to help validate transactions, earning rewards in return. Like "deposit interest" but with higher potential yields and risks.
CEX vs DEX: Complete Exchange Comparison
CEX (Centralized Exchange) is convenient but requires trusting the platform; DEX (Decentralized Exchange) gives you asset control but requires more technical knowledge. Both are essential parts of the crypto ecosystem.

Layer2 is a scaling solution built on Ethereum that processes transactions off-chain and submits compressed results to mainnet — faster and 90%+ cheaper.
Crypto Wallet Security: Essential Protection Measures
Crypto asset security centers on protecting your private key and seed phrase. Once compromised, assets are permanently and irrecoverably lost. Understanding attack vectors and defenses is critical.
Airdrop Farming 101: How to Earn Crypto Airdrops
Airdrop farming means using protocols/exchanges early, then earning free token rewards when they launch. Arbitrum, Optimism and similar airdrops have rewarded early users thousands of dollars.
How to Evaluate Airdrop Projects: Filter Quality Opportunities
Not all airdrops are worth farming. Learning to filter quality airdrops — checking team, funding, TVL growth, stability scores — maximizes your return on time and gas fees.
