🟢Quiz Questions:
Which stablecoin is an example of a crypto-collateralised model that uses over-collateralised debt positions?
🟢Choose one correct answer:
・USDS (formely DAI)
・USDT
・PYUSD
・FDUSD
🟢Answer:
USDS (formely DAI)
🟢Reason for choosing this answer:
USDS, formerly known as DAI, is a stablecoin that operates on a crypto-collateralized model. It is issued through the MakerDAO protocol and backed by over-collateralized debt positions, typically involving assets like Ethereum and other approved cryptocurrencies. This model requires users to lock in more collateral than the value of DAI they receive, ensuring stability even with crypto market volatility.
🟢Trivia:
DAI was one of the first decentralized stablecoins, and its over-collateralization mechanism makes it distinct from centralized stablecoins like USDT (Tether), which are backed by fiat reserves. This design offers more transparency and decentralization, appealing to users seeking a trustless system.
Daily Quiz on MAY 29
🟢Quiz Questions:
Which of the following accurately defines a fiat-collateralised stablecoin?
🟢Choose one correct answer:
・A token backed 1:1 by reserves of government-issued currency held in regulated bank accounts
・A token whose value floats freely with market demand
・A token backed solely by other volatile cryptocurrencies
・A token whose supply is balanced only by an algorithm without reserve assets
🟢Answer:
A token backed 1:1 by reserves of government-issued currency held in regulated bank accounts
🟢Reason for choosing this answer:
A fiat-collateralised stablecoin is designed to maintain a stable value by being fully backed by reserves of a fiat currency, such as USD or EUR. These reserves are held in regulated financial institutions, ensuring that each token issued can be redeemed for an equivalent amount of the fiat currency. This backing mechanism keeps the token price stable and directly pegged to the fiat currency it represents.
🟢Trivia:
One of the most well-known fiat-collateralised stablecoins is Tether (USDT), which claims to be backed 1:1 by U.S. dollar reserves. Other examples include USDC and BUSD. These stablecoins are widely used in cryptocurrency trading as a stable store of value and a medium of exchange.
Daily Quiz on MAY 28
🟢Quiz Questions:
“Slippage tolerance” sets an acceptable change in what?
🟢Choose one correct answer:
・Block Time
・Key Length
・Trade Price
・Fork Depth
🟢Answer:
Trade Price
🟢Reason for choosing this answer:
“Slippage tolerance” is a term commonly used in cryptocurrency and DeFi trading. It refers to the acceptable percentage difference between the expected price of a trade and the actual price at which the trade is executed. This setting helps traders manage the risk of price changes caused by market volatility or low liquidity during the execution of a transaction.
🟢Trivia:
On decentralized exchanges (DEXs) like Uniswap or PancakeSwap, slippage is a common issue due to the automated market maker (AMM) model. If the slippage tolerance is set too low, the trade may fail. If it’s set too high, traders might end up overpaying significantly, especially during high volatility or for low liquidity tokens.
Daily Quiz on MAY 27
🟢Quiz Questions:
Layer-2 rollups help DeFi primarily by lowering what?
🟢Choose one correct answer：
・Transaction Fees
・Token Decimal
・Node Counts
・Voting Quorum
🟢Answer:
Transaction Fees
🟢 Reason for choosing this answer:
Layer-2 rollups are designed to process transactions off the main Ethereum chain (Layer-1), aggregating many transactions into a single batch before posting back to Layer-1. This dramatically reduces the amount of data each individual transaction uses on the Ethereum blockchain, which in turn significantly lowers the gas fees users must pay. This cost-efficiency makes decentralized finance (DeFi) more accessible and scalable.
🟢 Trivia:
One popular type of Layer-2 rollup is the “zk-Rollup,” which uses zero-knowledge proofs to verify batches of transactions. Another type is the “Optimistic Rollup,” which assumes transactions are valid and only runs fraud proofs if challenged. Both aim to improve Ethereum’s scalability and user experience.
Daily Quiz on MAY 26
🟢Quiz Questions:
A bonding curve is used to manage what feature?
🟢Choose one correct answer:
・Gas Limits
・Token Supply
・Hash Rates
・Block Size
🟢Answer:
Token Supply
🟢Reason for choosing this answer:
A bonding curve is a mathematical curve that defines the relationship between the price and supply of a token. It is often used in decentralized finance (DeFi) and token economies to automatically adjust the token price based on demand and supply. When more tokens are bought, the price increases along the curve; when tokens are sold, the price decreases. This helps manage token issuance and ensures a dynamic, market-driven valuation.
🟢Trivia:
Bonding curves are especially popular in Initial DEX Offerings (IDOs) and NFT platforms, enabling automated market making and fundraising without needing traditional order books or centralized intermediaries. They can help bootstrap liquidity and incentivize early participation by pricing early tokens lower on the curve.
Daily Quiz on MAY 25
🟢Quiz Questions:
Chainlink mainly provides DeFi with what service?
🟢Choose one correct answer:
・Cold Storage

This interoperability bridges the gap between the Bitcoin and Ethereum ecosystems, enabling Bitcoin holders to participate in DeFi services such as lending, trading, and liquidity provision on Ethereum.
🟢Trivia:
WBTC is governed by a decentralized autonomous organization (DAO) called the WBTC DAO, composed of numerous projects in the DeFi space. The Bitcoin backing each WBTC is held by custodians, and its creation or burning is handled by merchants who interact with users. This system ensures that each WBTC token is verifiably backed by actual BTC reserves.
Daily Quiz on MAY 21
🟢Quiz Questions:
Which concept allows DeFi apps to stack on each other?
🟢Choose one correct answer:
・Money Legos
・Money Stacks
・Financial Legos
・Financial Stacks
🟢Answer:
Money Legos
🟢Reason for choosing this answer:
The term “Money Legos” is widely used in the DeFi (Decentralized Finance) ecosystem to describe how DeFi protocols are composable. This means they can be combined like building blocks—just like Lego pieces—allowing developers to create more complex financial applications by stacking various DeFi tools and services.
🟢Trivia:
The “Money Legos” concept was popularized by Ethereum-based projects, especially during the DeFi boom of 2020. It underscores the open-source and interoperable nature of DeFi, where one application (e.g., lending) can be built on top of another (e.g., decentralized exchange) to create innovative financial products without the need for centralized intermediaries.
Daily Quiz on MAY 20
🟢Quiz Questions:
Providing ETH and USDC to Uniswap v3 is called what?
🟢Choose one correct answer:
・Plasma Staking
・Batch Finality
・Concentrated Liquidity
・v3 Mining
🟢Answer:
Concentrated Liquidity
🟢Reason for choosing this answer:
Uniswap v3 introduced the concept of concentrated liquidity, allowing liquidity providers (LPs) to allocate liquidity within custom price ranges. This innovation improves capital efficiency by letting LPs choose the price range where they want their assets (like ETH and USDC) to be active. Other options like “Plasma Staking” and “Batch Finality” are unrelated to liquidity provision, and “v3 Mining” is not an official term used for this function.
🟢Trivia:
With concentrated liquidity, LPs can earn more fees using less capital, but they also face a higher risk of impermanent loss if the market price moves out of their specified range. This system makes Uniswap v3 more flexible and powerful compared to its predecessors.
Daily Quiz on MAY 19
🟢Quiz Questions:
Yearn Finance is best known for offering what service?
🟢Choose one correct answer:
・Cross-Chain Bridge
・Yield Aggregation

Yield Aggregation
🟢Reason for choosing this answer:
Yearn Finance is a decentralized finance (DeFi) protocol built on Ethereum, and it is best known for its yield aggregation services. The platform automates the process of finding the best yield farming opportunities across DeFi protocols. It collects user deposits and allocates them across different DeFi strategies to maximize returns, hence the term “yield aggregator.”
🟢Trivia:
The core product of Yearn Finance is the “Vault”, where users deposit assets, and the protocol automatically implements strategies to generate the highest yield. Yearn Finance gained massive popularity in 2020 and its native token, YFI, was notable for having no premine and being distributed entirely to users, embodying decentralization.
Daily Quiz on MAY 18
🟢Quiz Questions:
Governance tokens mainly grant holders what power?
🟢Choose one correct answer:
・Miner Rewards
・Price Oracle
・Protocol Voting
・Gas Refunds
🟢Answer:
Protocol Voting
🟢Reason for choosing this answer:
Governance tokens empower holders to influence the future of a blockchain protocol by allowing them to vote on key decisions. This may include upgrades, fee structures, development fund allocations, or other essential protocol parameters. The purpose is to enable decentralized, user-driven governance without relying on a centralized authority.
🟢Trivia:
Representative governance tokens include Uniswap’s UNI and Compound’s COMP. UNI holders can vote on proposals concerning liquidity mining rewards, fee structures, and treasury usage. COMP holders participate in decisions about interest rate models or adding new assets to the platform.
In Xenea, the native token XENE also functions as a governance token. It is designed to be used in voting on Xenea Improvement Proposals (CIP), which may involve changes to network parameters and economic models such as the inflation rate. This framework empowers users and fosters true decentralized governance within the Web3 ecosystem.
Daily Quiz on MAY 15
🟢Quiz Questions:
“TVL” in DeFi means what?
🟢Choose one correct answer:
・Total Value Locked
・Transaction Verify Level
・Token Volume Limit
・Trustless Vault Ledger
🟢Answer:
Total Value Locked
🟢Reason for choosing this answer:
“TVL” stands for Total Value Locked, which refers to the total amount of assets that are currently staked or locked in a DeFi (Decentralized Finance) protocol. This metric helps assess the overall health, usage, and popularity of a DeFi platform, as it reflects the total capital committed by users.
🟢Trivia:
TVL is commonly used to compare DeFi platforms such as Uniswap, Aave, and Compound. A higher TVL often indicates higher user trust and platform liquidity. However, it’s important to note that TVL alone doesn’t guarantee the safety or profitability of a platform—it should be considered along with other metrics like user count, tokenomics, and smart contract audits.
Daily Quiz on MAY 14
🟢Quiz Questions:
DAI, FRAX, and USDC are examples of what asset type?
🟢Choose one correct answer:
・Reward Points
・Stable Coins
・Privacy Coins
・Meme Tokens
🟢Answer:
Stable Coins
🟢 Reason for choosing this answer:
DAI, FRAX, and USDC are all categorized as stablecoins—a type of cryptocurrency designed to maintain a stable value, often pegged to a fiat currency like the US Dollar. Unlike other cryptocurrencies that can be highly volatile, stablecoins aim to provide price stability, making them useful for trading, remittances, and daily transactions.
🟢 Trivia:
Stablecoins can be categorized into three types:
1. Fiat-collateralized (e.g., USDC) – backed by reserves like USD held in a bank.
2. Crypto-collateralized (e.g., DAI) – backed by other cryptocurrencies.
3. Algorithmic (e.g., FRAX originally used a hybrid approach) – rely on algorithms to control supply and demand.
These assets are playing a vital role in bridging traditional finance and decentralized finance (DeFi).
Daily Quiz on MAY 13
🟢Quiz Questions:
A “flash loan” must be block. within one
🟢Choose one correct answer:
・Double Signed
・Partially Staked
・Time ocked
・Fully Repaid
🟢Answer:
Fully Repaid
🟢Reason for choosing this answer:
Flash loans are a unique feature of decentralized finance (DeFi) that allow users to borrow assets without collateral, under the condition that the loan is repaid within the same blockchain transaction (i.e., within one block). If the borrower fails to repay the loan in full within the block, the entire transaction is reverted, as if it never happened. Therefore, “Fully Repaid” is the correct answer.
🟢Trivia:
Flash loans are often used for arbitrage opportunities, collateral swaps, or refinancing purposes. However, they have also been exploited in DeFi hacks due to their speed and complexity. One notable case was the bZx protocol attack, where attackers manipulated asset prices within a single transaction using flash loans.
Daily Quiz on MAY 12
🟢Quiz Questions:
Which mechanism sets prices in automated market makers?
🟢Choose one correct answer:
・Sharding Ledger
・Trading Volume
・Total Value Locked
・Constant Product
🟢Answer:
Constant Product
🟢Reason for choosing this answer:
The pricing mechanism in automated market makers (AMMs) like Uniswap is based on the constant product formula, often represented as xy = k*, where x and y are the quantities of two tokens in a liquidity pool, and k is a constant. This ensures that as one token is bought and its supply decreases, its price increases in order to maintain the product constant. This model guarantees that the pool never runs out of either token, as price tends toward infinity as reserves dwindle.
🟢Trivia:
Uniswap was the first major decentralized exchange to popularize the constant product formula. This model laid the groundwork for a wide range of AMMs in the DeFi ecosystem. One interesting property of this formula is “slippage”—the more of a token you try to buy at once, the worse your rate becomes, due to the curve shape of the formula.
Daily Quiz on MAY 11
🟢Quiz Questions:
What risk is unique to providing a two-token pool?
🟢Choose one correct answer:
・Impermanent Loss
・Network Latency
・Hard Fork Risk
・Double Spending
🟢Answer:
Impermanent Loss
🟢Reason for choosing this answer:
Impermanent loss is a risk unique to providing liquidity in decentralized finance (DeFi), especially in two-token pools (like ETH/USDC) on automated market makers (AMMs) such as Uniswap. It occurs when the price ratio of the two tokens changes after you’ve deposited them, resulting in a potential loss when you withdraw them compared to simply holding the tokens.
🟢Trivia:
Impermanent loss isn’t actually realized until you withdraw your tokens from the pool. If the token prices return to their original ratio, the loss can disappear—hence the term “impermanent.” However, large price divergences can lead to significant and permanent losses if withdrawn at the wrong time. Some protocols, like Bancor and Curve, have introduced innovations to mitigate this risk.
Daily Quiz on MAY 10
🟢Quiz Questions:
Which term describes profits earned for supplying liquidity?
🟢Choose one correct answer:
・Liquidity Mining
・Gas Farming
・Token Burning
・Hash Staking
🟢Answer:
Liquidity Mining
🟢Reason for choosing this answer:
“Liquidity Mining” refers to the process where users provide liquidity to decentralized finance (DeFi) protocols (usually by depositing their tokens into liquidity pools), and in return, they earn rewards. These rewards can be in the form of transaction fees, interest, or additional tokens, and represent the “profits earned for supplying liquidity.” The other options relate to different aspects of blockchain and crypto systems but not directly to liquidity provisioning profits.
🟢Trivia:
The concept of liquidity mining gained popularity with the rise of DeFi platforms like Uniswap and Compound. It not only incentivizes users to provide liquidity but also helps projects distribute their tokens more fairly by rewarding early contributors. Some protocols even offer “double rewards” – native tokens plus governance tokens – for extra incentives.
Daily Quiz on MAY 9
🟢Quiz Questions:
What does “DEX” stand for in DeFi?
🟢Choose one correct answer:
・Digital Exchange
・Data Exchange
