Quiz: Token Economics
Question 1
At the most fundamental level, an ERC-20 token is best described as:
A) A digital coin stored in a user's wallet application B) An entry in a smart contract's mapping that tracks balances per address C) A file on the blockchain that represents ownership of an asset D) A cryptographic hash that proves ownership of value
Answer: B
Explanation: An ERC-20 token is a smart contract maintaining a mapping(address => uint256) — a data structure that maps addresses to balances. There is no "coin" or "file." The wallet application reads the mapping to display a balance, but the balance exists only as a storage slot in the contract. Understanding this is foundational to understanding everything else about tokenomics: the contract's code defines reality, and value is entirely external to the contract.
Question 2
Which ERC standard supports batch transfers of multiple token types in a single transaction?
A) ERC-20 B) ERC-721 C) ERC-1155 D) ERC-4626
Answer: C
Explanation: ERC-1155 introduces safeBatchTransferFrom, which allows transferring multiple token types (each identified by a unique ID) with different amounts in a single transaction. This dramatically reduces gas costs for applications like gaming where users may trade dozens of items at once. ERC-20 and ERC-721 only support single-token-type transfers per transaction. ERC-4626 is a vault standard that extends ERC-20.
Question 3
A token with a fixed maximum supply of 10 million tokens, all minted at deployment, is considering how to fund ongoing protocol development. What is the primary disadvantage of the fixed-supply model in this context?
A) Fixed supply makes the token a security under the Howey Test B) Fixed supply prevents the protocol from creating new tokens to incentivize future participants C) Fixed supply causes deflation, making the token unusable as a medium of exchange D) Fixed supply requires all tokens to be distributed at launch
Answer: B
Explanation: With a fixed supply, once all tokens are distributed, there are no new tokens to reward future contributors, liquidity providers, or ecosystem participants. This is why many fixed-supply tokens reserve a large allocation (often 25-40%) for future ecosystem incentives. Option A is incorrect because supply model alone does not determine Howey Test outcomes. Option C conflates fixed supply with deflation (fixed supply is neither inflationary nor deflationary — the total supply simply does not change). Option D is incorrect because tokens can be reserved in treasury for later distribution.
Question 4
In Ethereum's post-merge tokenomics, ETH becomes net deflationary when:
A) Validators stake more than 50% of total ETH supply B) The base fee burned via EIP-1559 exceeds the staking rewards issued C) The total supply reaches a predefined maximum D) Governance votes to reduce the staking reward rate
Answer: B
Explanation: Ethereum's post-merge economics has two competing forces: staking rewards (inflationary — new ETH is created) and EIP-1559 base fee burns (deflationary — ETH is destroyed). When network activity is high enough that burns exceed issuance, ETH is net deflationary. When network activity is low, ETH is net inflationary. This dynamic supply model ties supply to demand. The community calls net deflationary ETH "ultrasound money."
Question 5
Which of the following best describes the "velocity problem" in utility token economics?
A) Tokens move too slowly between wallets, reducing liquidity B) Tokens are used and immediately resold, suppressing market capitalization relative to economic activity C) Token transactions are too fast for governance to respond to market changes D) Token price volatility makes the token impractical for payments
Answer: B
Explanation: The velocity problem, formalized through the equation M x V = P x Q, states that when tokens change hands rapidly (high velocity), the market capitalization (M) required to support a given level of economic activity (PQ) is low. If users buy a utility token, use it instantly, and the recipient sells it instantly, the token's market cap is a fraction of the total economic activity it supports. Solutions include staking (removing tokens from circulation), burn-and-mint mechanics, and holding incentives.
Question 6
The Howey Test defines a security as a transaction involving all of the following EXCEPT:
A) An investment of money B) In a common enterprise C) Registration with a government securities regulator D) With an expectation of profits derived primarily from the efforts of others
Answer: C
Explanation: The Howey Test has four prongs: (1) investment of money, (2) in a common enterprise, (3) with an expectation of profits, (4) derived primarily from the efforts of others. Registration is not a prong of the test — it is the legal obligation that results from meeting the test. A token can be a security under the Howey Test regardless of whether it has been registered. Indeed, the SEC's enforcement actions are specifically against tokens that meet the Howey Test but were NOT registered.
Question 7
A token project distributes 40% to community via airdrop, 20% to treasury, 15% to team (4-year vest, 1-year cliff), 15% to contributors (2-year vest), and 10% to ecosystem. What is the approximate circulating supply immediately after launch (day 0)?
A) 40% — only the community airdrop is liquid B) 50% — community airdrop plus ecosystem fund C) 60% — community airdrop plus treasury D) 100% — all tokens exist even if some are locked
Answer: A
Explanation: On day 0, only the community/airdrop allocation (40%) is immediately liquid. The team tokens are locked by a 1-year cliff. The contributor tokens have a 6-month cliff. The treasury requires DAO governance votes to release. The ecosystem fund is released over 3 years. While all 100% of tokens technically exist on-chain, only 40% are freely circulating. The distinction between "total supply" and "circulating supply" is critical for understanding market dynamics and fully diluted valuation.
Question 8
The Beanstalk governance attack in April 2022 was possible because:
A) The protocol's smart contract had a reentrancy vulnerability B) An attacker used a flash loan to temporarily acquire enough governance tokens to pass a malicious proposal in a single transaction C) A 51% attack on the underlying blockchain allowed transaction reordering D) The protocol's admin keys were compromised through a phishing attack
Answer: B
Explanation: The Beanstalk attack exploited the fact that governance voting power was based on current token holdings, which could be temporarily obtained through a flash loan. The attacker borrowed enough governance tokens, voted to pass a malicious proposal that drained $182 million from the protocol, repaid the flash loan, and pocketed the difference — all in a single atomic transaction. This attack demonstrated the danger of governance systems that allow instant proposal execution without timelocks or snapshot-based voting.
Question 9
Which of the following is a valid mitigation for the voter apathy problem in DAO governance?
A) Increasing the minimum token holding required to vote B) Making all voting mandatory with penalties for non-participation C) Enabling delegation so token holders can assign their voting power to informed delegates D) Restricting voting rights to the founding team
Answer: C
Explanation: Delegation addresses voter apathy by allowing token holders who lack time or expertise to assign their voting power to delegates who actively follow proposals. This maintains decentralized governance while improving participation quality. Option A would worsen apathy by excluding small holders. Option B is impractical in pseudonymous systems and could be considered coercive. Option D is centralization, not a solution to governance apathy.
Question 10
A "fair launch" token distribution is characterized by:
A) Tokens being sold at a fair market price determined by an auction B) No pre-mine — no tokens allocated to founders, investors, or insiders before public distribution C) Equal distribution of tokens to every wallet address on the network D) Distribution through a regulated securities offering with full disclosure
Answer: B
Explanation: A fair launch means there is no pre-allocation of tokens to any privileged party. Bitcoin is the purest example — Satoshi published the code and anyone could mine from block 1. Yearn Finance (YFI) conducted a fair launch where all tokens were distributed through liquidity mining with zero team allocation. The advantage is legitimacy; the disadvantage is that the development team receives no direct funding, which can hamper long-term development.
Question 11
In a vesting schedule with a 12-month cliff and 48-month total duration, what happens at month 13?
A) 1/48 of the total allocation becomes available B) 12/48 (25%) becomes available at the cliff, then 1/48 vests for month 13 C) The full allocation becomes available because the cliff has passed D) Nothing — tokens only vest at the end of the 48-month period
Answer: B
Explanation: At month 12 (the cliff), 12/48 = 25% of the total allocation vests at once. From month 13 onward, an additional 1/48 (~2.08%) vests each month. So at month 13, the beneficiary has access to 13/48 (~27.08%) of their total allocation. The cliff creates a "step function" at month 12 where a large chunk unlocks at once, followed by smooth linear vesting. This cliff unlock is why major token unlock dates create predictable selling pressure.
Question 12
Which scenario best illustrates "mercenary capital" in DeFi?
A) A venture capital firm that invests in a protocol's token sale and holds for five years B) A liquidity provider who deposits capital into a pool purely to farm token rewards, then withdraws and sells when rewards decrease C) A developer who contributes code to a protocol in exchange for a token grant with a 4-year vesting schedule D) A governance delegate who votes on every proposal to earn participation rewards
Answer: B
Explanation: Mercenary capital describes liquidity providers who are attracted purely by token incentives (liquidity mining rewards), with no long-term commitment to the protocol. They deposit capital when rewards are high, sell the reward tokens immediately, and withdraw their capital when rewards decrease — leaving the protocol with less liquidity and a depressed token price. This was a pervasive pattern in DeFi 2020-2022 and is the primary argument against simple liquidity mining programs.
Question 13
ERC-4626 standardizes:
A) Non-fungible token metadata formats B) Cross-chain token bridge interfaces C) Yield-bearing tokenized vault deposits and withdrawals D) Token governance and voting mechanics
Answer: C
Explanation: ERC-4626 is the Tokenized Vault Standard, which provides a standard interface for yield-bearing vaults. Before ERC-4626, every lending protocol (Aave, Compound, Yearn) had its own proprietary interface for deposits, withdrawals, and share-to-asset conversions. ERC-4626 standardizes these operations, making vault tokens composable across the DeFi ecosystem. It extends ERC-20 with functions like deposit, withdraw, convertToShares, and convertToAssets.
Question 14
A token has strong utility (required to pay for a genuinely useful service), was distributed via a free airdrop to past users, and is governed by a fully decentralized DAO with no centralized team. Under the Howey Test, the WEAKEST prong for calling this token a security is:
A) Investment of money B) Common enterprise C) Expectation of profits D) All prongs are equally weak
Answer: A
Explanation: The "investment of money" prong is weakest because the tokens were distributed via a free airdrop — recipients did not pay anything. If there is no investment of money, the first prong fails, and the token is unlikely to be a security regardless of the other prongs. The strong utility weakens the "expectation of profits" prong (users may buy for utility, not profit). The decentralized DAO weakens the "efforts of others" prong (there is no centralized team whose efforts drive value). But the free distribution most directly undermines the Howey analysis.
Question 15
Which of the following supply models is most vulnerable to a "death spiral" where declining demand causes accelerating token devaluation?
A) Fixed supply with no burn mechanism B) Inflationary supply where new tokens fund user rewards that attract new users C) Deflationary supply with aggressive burn on every transfer D) Dual-token model with a capped governance token and an uncapped utility token
Answer: B
Explanation: An inflationary model where emissions fund user acquisition rewards is most vulnerable to a death spiral. The mechanism: growth slows, so fewer new users arrive, so token demand decreases, so the price drops, so the dollar value of rewards drops, so even fewer new users are attracted, so the price drops further. Each step reinforces the next. This is precisely what happened to Axie Infinity's SLP token. Fixed supply (A) cannot death-spiral because no new tokens are created. Aggressive burn (C) may reduce liquidity but does not create a reflexive doom loop. Dual-token (D) isolates the governance token from the utility token's volatility.
