n. — tokenomics metric; market valuation
Circulating supply refers to the total number of cryptocurrency tokens or coins that are publicly available and actively circulating in the market at a given point in time. It excludes tokens that are locked, reserved, vested, burned, or otherwise removed from active circulation. Circulating supply is the primary input used to calculate a cryptocurrency's market capitalization and serves as a key indicator of a token's liquidity profile and inflationary pressure.
Primary Formula
Market Cap = Circulating Supply × Current Price (USD)
Distinct from Total Supply (all minted minus burned) and Maximum Supply (hard protocol cap).
ANALYTICAL NOTE: For Bitcoin, the maximum supply is fixed at 21,000,000 BTC by protocol consensus. Discrepancies between circulating and total supply often indicate vesting schedules, team allocations, or treasury reserves. Data providers such as CoinGecko and CoinMarketCap may report differing circulating supply figures due to methodological differences in classifying locked tokens.
n. — valuation metric; market structure
Market capitalization (commonly abbreviated as market cap) is the total market value of a cryptocurrency's circulating supply, calculated by multiplying the current price per unit by the number of tokens in active circulation. It is the most widely used metric for ranking and comparing the relative size of cryptocurrency projects and is analogous to the equity market capitalization of publicly traded companies.
Formula
Market Cap = Circulating Supply × Price Per Token
Large-cap: >$10B · Mid-cap: $1B–$10B · Small-cap: $100M–$1B · Micro-cap: <$100M
ANALYTICAL NOTE: Market cap is a snapshot metric and does not reflect liquidity, trading volume, or the actual capital required to move the price. A token with low float and high price can exhibit a large market cap while remaining highly illiquid. Critics prefer Realized Cap — the sum of all UTXOs valued at the price when last moved — as a more conservative valuation baseline for Bitcoin.
n. — tokenomics metric; issuance accounting
Total supply is the total number of tokens that have been created (minted) and currently exist on a blockchain, minus any tokens that have been permanently destroyed (burned). It represents all tokens in existence regardless of whether they are actively circulating, locked in smart contracts, held in team or foundation wallets, or subject to vesting schedules. Total supply is always greater than or equal to circulating supply and less than or equal to maximum supply.
Accounting Identity
Total Supply = Minted Tokens − Burned Tokens
Always: Circulating Supply ≤ Total Supply ≤ Maximum Supply
ACCOUNTING NOTE: Projects with a large gap between total and circulating supply may face significant future sell pressure as locked tokens unlock over time — a dynamic known as token overhang. Forensic analysis of token distribution wallets can reveal whether "locked" tokens are genuinely inaccessible or merely held in team-controlled addresses with no binding smart contract restriction.
n. — tokenomics metric; protocol parameter
Maximum supply is the absolute hard cap on the total number of tokens that will ever exist for a given cryptocurrency, as defined by its underlying protocol or smart contract logic. Once the maximum supply is reached, no new tokens can be minted. Not all cryptocurrencies have a defined maximum supply; those without one are described as having an uncapped or infinite supply, though issuance rates may still be algorithmically controlled.
PROTOCOL NOTE: Bitcoin's maximum supply of 21,000,000 BTC is enforced by the protocol's halving schedule, which reduces the block subsidy by 50% approximately every 210,000 blocks (~4 years). The final satoshi is projected to be mined around the year 2140. Ethereum does not have a hard maximum supply cap; however, EIP-1559 introduced a base fee burn mechanism that can render ETH net deflationary under high network demand conditions.
n. — issuance mechanism; incentive alignment
Token vesting is a time-based release schedule that restricts the transferability of tokens allocated to founders, team members, advisors, and early investors for a defined period following a project's launch or token generation event (TGE). Vesting schedules are designed to align long-term incentives, prevent immediate sell pressure from insiders, and signal commitment to the project's development. Vesting is typically implemented via smart contracts that release tokens incrementally over a cliff-and-linear schedule.
STRUCTURAL NOTE: A common vesting structure includes a cliff period (e.g., 12 months during which no tokens are released) followed by a linear vesting period (e.g., monthly releases over 24–36 months). Investors and analysts scrutinize vesting schedules as a leading indicator of future sell pressure. Projects that obscure or modify vesting terms post-launch have been associated with exit scam patterns documented in The Vault.
n. — token economic model; supply mechanics
A deflationary token is a cryptocurrency designed with mechanisms that reduce the total supply over time, theoretically creating upward price pressure as scarcity increases relative to demand. The primary deflationary mechanism is token burning — the permanent, irreversible destruction of tokens by sending them to an unspendable address (a "burn address"). Additional deflationary mechanisms include buyback-and-burn programs, transaction fee burns, and protocol-level supply caps.
ECONOMIC NOTE: Ethereum's EIP-1559 (August 2021) introduced a base fee burn that has rendered ETH net deflationary during periods of high network activity. BNB employs a quarterly burn mechanism tied to Binance exchange revenue. Critics note that aggressive deflationary tokenomics can incentivize hoarding over utility, and that "burn" mechanisms are sometimes used as marketing tools without meaningful economic impact when the burned quantity is negligible relative to total supply.
n. — market structure; trading mechanics
Liquidity in cryptocurrency markets refers to the ease with which a digital asset can be bought or sold at a stable price without causing significant price impact. A highly liquid market is characterized by tight bid-ask spreads, deep order books, and high trading volume, enabling large transactions to be executed with minimal slippage. Liquidity is a function of both the number of market participants and the depth of capital committed to market-making activities.
MARKET STRUCTURE NOTE: In decentralized finance (DeFi), liquidity is provided by liquidity providers (LPs) who deposit token pairs into automated market maker (AMM) pools in exchange for a share of trading fees. Liquidity is measured by Total Value Locked (TVL) in DeFi protocols. Thin liquidity is a primary risk factor in smaller-cap tokens and is frequently exploited in price manipulation schemes such as pump-and-dump operations.
n. — DeFi protocol; decentralized exchange mechanism
An Automated Market Maker (AMM) is a type of decentralized exchange (DEX) protocol that uses algorithmic pricing formulas and on-chain liquidity pools to facilitate token swaps without requiring a traditional order book or centralized counterparty. Instead of matching buyers and sellers directly, AMMs price assets according to a mathematical invariant maintained by the liquidity pool. The most widely adopted model is the constant product formula (x × y = k), pioneered by Uniswap.
Constant Product Formula (Uniswap v2)
x × y = k
Where x and y are the reserves of two tokens, and k is a constant. Price is determined by the ratio of reserves.
PROTOCOL NOTE: AMMs were popularized by Uniswap (launched 2018) and subsequently adopted by SushiSwap, Curve Finance, Balancer, and others. Curve Finance introduced the stableswap invariant, optimized for assets of near-equal value (e.g., stablecoin pairs). Liquidity providers in AMMs are exposed to impermanent loss — a divergence loss relative to simply holding the underlying assets — when token prices diverge significantly.
n. — DeFi metric; protocol health indicator
Total Value Locked (TVL) is the aggregate value of all digital assets deposited and actively utilized within a decentralized finance (DeFi) protocol or ecosystem at a given point in time. TVL encompasses assets committed to liquidity pools, lending protocols, yield vaults, staking contracts, and other smart contract-based financial instruments. It is the primary benchmark metric for measuring the adoption, scale, and relative dominance of DeFi protocols.
ANALYTICAL NOTE: TVL is denominated in USD and is subject to double-counting when assets are deposited across multiple protocols. DeFiLlama is the primary data aggregator for cross-chain TVL. TVL peaked across the DeFi ecosystem at approximately $180 billion in November 2021 before declining sharply during the 2022 bear market. TVL alone is an insufficient measure of protocol quality; it must be evaluated alongside revenue, user activity, and security audit history.
n. — DeFi strategy; liquidity incentive mechanism
Yield farming (also known as liquidity mining) is the practice of deploying cryptocurrency assets across one or more DeFi protocols to generate returns in the form of interest, trading fees, and governance token rewards. Yield farmers actively optimize their capital allocation across protocols, often using leverage and complex multi-step strategies to maximize annual percentage yield (APY). The practice was catalyzed by Compound Finance's launch of COMP token distribution in June 2020, which initiated the "DeFi Summer" period of explosive protocol growth.
RISK NOTE: Yield farming carries compounded risks including smart contract vulnerabilities, impermanent loss, liquidation risk (when using leverage), governance token price volatility, and protocol rug pulls. Advertised APYs are frequently unsustainable and decline rapidly as more capital enters a protocol. The SEC has indicated that certain yield farming arrangements may constitute unregistered securities offerings depending on the structure of token rewards.
n. — valuation metric; forward-looking market cap
Fully Diluted Valuation (FDV) is the hypothetical total market capitalization of a cryptocurrency if its entire maximum supply were in circulation at the current market price. FDV represents the theoretical upper bound of a project's market cap, assuming all tokens — including those locked, vested, reserved, or yet to be minted — were immediately available and priced at the current rate. It is a forward-looking metric used to assess the potential dilution risk faced by current token holders.
Formula
FDV = Maximum Supply × Current Price Per Token
A high FDV-to-Market-Cap ratio indicates significant future token unlocks and potential sell pressure.
VALUATION NOTE: A large disparity between FDV and market cap is a key due diligence signal. For example, a token with a $500M market cap but a $10B FDV implies that 95% of the supply has yet to enter circulation — representing substantial future dilution. Sophisticated investors use the FDV/TVL ratio as a relative valuation metric for DeFi protocols, with ratios below 1.0 historically considered undervalued.
n. — portmanteau; economic design discipline
Tokenomics is a portmanteau of "token" and "economics" referring to the study and design of the economic systems, incentive structures, and supply-demand mechanics governing a cryptocurrency or digital token. A project's tokenomics encompasses its total and maximum supply, issuance schedule, distribution model, utility mechanisms, governance rights, burn mechanisms, vesting schedules, and the behavioral incentives encoded into its protocol. Well-designed tokenomics align the interests of all stakeholders — developers, investors, users, and validators — toward the long-term health of the network.
ANALYTICAL FRAMEWORK: Forensic analysis of tokenomics examines: (1) supply concentration — what percentage of tokens are held by insiders; (2) unlock schedules — when and how locked tokens enter circulation; (3) utility — whether token demand is driven by genuine protocol usage or speculative incentives; (4) governance — whether token holders have meaningful control; and (5) sustainability — whether the protocol's revenue model can support its token price without relying on continuous new capital inflows, a hallmark of Ponzi dynamics.
n. — token category; price-stability mechanism
A stablecoin is a class of cryptocurrency designed to maintain a stable value relative to a reference asset — most commonly the U.S. dollar — through one of several collateralization or algorithmic mechanisms. Stablecoins serve as the primary medium of exchange and unit of account within DeFi ecosystems, enabling participants to transact, lend, and earn yield without exposure to the price volatility of non-pegged cryptocurrencies. The three primary stablecoin architectures are: (1) fiat-collateralized (e.g., USDC, USDT); (2) crypto-collateralized (e.g., DAI); and (3) algorithmic (e.g., the failed TerraUSD/UST).
REGULATORY NOTE: Stablecoins are under active regulatory scrutiny globally. The U.S. Congress has debated multiple stablecoin bills requiring reserve audits and redemption guarantees. The EU's MiCA regulation (effective 2024) imposes reserve, redemption, and operational requirements on stablecoin issuers. The collapse of TerraUSD (UST) in May 2022 — which erased approximately $40 billion in market value within 72 hours — accelerated regulatory urgency and is documented in full in The Vault.
n. — DeFi risk; liquidity provision mechanics
Impermanent loss is the temporary reduction in value experienced by a liquidity provider (LP) in an automated market maker (AMM) pool relative to simply holding the same assets outside the pool. It occurs when the price ratio of the two tokens in a liquidity pool diverges from the ratio at the time of deposit. The loss is termed "impermanent" because it is only realized upon withdrawal; if prices return to their original ratio, the loss disappears. However, in practice, impermanent loss frequently becomes permanent when LPs withdraw during periods of price divergence.
Impermanent Loss Approximation
IL ≈ 2√r / (1 + r) − 1 where r = price ratio change
2x price change ≈ 5.7% IL · 5x price change ≈ 25.5% IL · 10x price change ≈ 42.5% IL
QUANTITATIVE NOTE: Concentrated liquidity AMMs (e.g., Uniswap v3) amplify both fee income and impermanent loss exposure within defined price ranges. LPs must ensure that accumulated trading fees exceed impermanent loss to achieve net positive returns. Stablecoin-to-stablecoin pools (e.g., USDC/USDT on Curve) experience near-zero impermanent loss due to minimal price divergence between assets.
n. — supply reduction mechanism; on-chain operation
A token burn is the deliberate and permanent removal of a quantity of cryptocurrency tokens from circulation by sending them to a provably unspendable wallet address — commonly referred to as a burn address or null address — from which they can never be retrieved. Because the private key to a burn address is mathematically impossible to derive, any tokens sent to it are irreversibly destroyed, reducing the total supply. Token burns are a primary mechanism for implementing deflationary tokenomics.
TECHNICAL NOTE: On Ethereum, the canonical burn address is 0x000...dEaD. On Bitcoin, unspendable outputs are created using OP_RETURN scripts. Proof of burn is verifiable on-chain by any observer. Scheduled burns (e.g., Binance's quarterly BNB burns) are distinct from protocol-level burns (e.g., Ethereum's EIP-1559 base fee burn), which occur automatically with every transaction. The economic impact of a burn is proportional to the burned quantity relative to total supply.
n. — trading mechanics; price impact
Slippage is the difference between the expected price of a trade and the actual executed price, caused by market movement or insufficient liquidity between the time a trade is initiated and when it is confirmed on-chain. In AMM-based DEXs, slippage is a direct function of trade size relative to pool depth: larger trades consume a greater proportion of pool reserves, moving the price along the bonding curve and resulting in a worse execution price. Slippage tolerance is a user-configurable parameter in DEX interfaces that sets the maximum acceptable deviation from the quoted price.
TRADING NOTE: High slippage tolerance settings (e.g., >5%) are frequently required for low-liquidity tokens but expose traders to sandwich attacks — a form of MEV (Maximal Extractable Value) exploitation in which a bot detects a pending transaction, front-runs it with a buy order, and back-runs it with a sell order, profiting from the price movement caused by the victim's trade.
