Algorithmic StablecoinTypes
A stablecoin that maintains its peg through algorithmic mechanisms—smart contracts that expand or contract supply—rather than holding collateral reserves.

Example

TerraUSD (UST) was an algorithmic stablecoin that maintained its $1 peg by allowing users to burn $1 of LUNA to mint 1 UST, and vice versa.

Asset-Referenced Token (ART)Regulation
Under MiCA, a crypto-asset that purports to maintain a stable value by referencing several currencies, commodities, or crypto-assets.

Example

A token pegged to a basket of USD, EUR, and gold would be classified as an ART under MiCA.

AttestationCompliance
An independent third-party verification that an issuer's stated reserves are accurate at a given point in time. Less rigorous than a full audit.

Example

Circle publishes monthly USDC reserve attestations from Deloitte confirming that reserve assets equal or exceed circulating USDC supply.

Audit (Reserve)Compliance
A formal examination of an issuer's financial records by a licensed accounting firm confirming that reserves are held as claimed, with opinion on financial statements.

Example

A full reserve audit would review bank statements, custody agreements, and legal ownership documentation—going beyond a simple attestation.

BurnMechanics
The process of permanently removing tokens from circulation, typically by sending them to a provably unspendable address. Used in stablecoin issuance cycles.

Example

When a user redeems 1,000 USDC for $1,000, Circle burns 1,000 USDC tokens and withdraws $1,000 from reserves.

CBDCDigital Money
Central Bank Digital Currency — a digital form of a country's fiat currency issued and backed directly by the central bank.

Example

The Digital Euro, Digital Yuan (e-CNY), and the UK Digital Pound are all active CBDC initiatives.

Circulating SupplyMarket
The total number of stablecoin tokens currently in existence and not locked or burned.

Example

If USDT has 120 billion tokens in circulating supply at $1 each, its market cap is $120 billion.

CollateralMechanics
Assets pledged to back a loan or to back the issuance of stablecoins. The value and quality of collateral directly affects the stability of a stablecoin.

Example

DAI uses ETH and other crypto assets as collateral, requiring users to lock up more than $1 of crypto to mint $1 of DAI.

Commodity-Backed StablecoinTypes
A stablecoin whose value is pegged to a physical commodity, typically gold, with each token representing ownership of a specific quantity of the commodity.

Example

Pax Gold (PAXG) pegs each token to one troy ounce of gold held in Brink's vaults in London.

Crypto-Collateralized StablecoinTypes
A stablecoin backed by other cryptocurrencies as collateral, typically requiring over-collateralization to absorb price volatility.

Example

DAI is the leading crypto-collateralized stablecoin, issued by MakerDAO and backed by ETH, WBTC, and other approved assets.

DAIExamples
MakerDAO's decentralized stablecoin, pegged to the US Dollar and backed by over-collateralized crypto assets via smart contracts on Ethereum.

Example

A user can lock $1,500 of ETH to mint $1,000 of DAI, maintaining a 150% collateralization ratio.

Death SpiralRisk
A self-reinforcing collapse mechanism in algorithmic stablecoins where falling stablecoin price triggers token minting, which dilutes governance token value, further undermining confidence.

Example

The May 2022 UST collapse is the defining example of a death spiral in practice.

DeFi (Decentralized Finance)Ecosystem
Financial services—lending, borrowing, trading—built on blockchain smart contracts, operating without centralized intermediaries.

Example

Aave allows users to deposit USDC and earn interest, while borrowers can take out stablecoin loans against crypto collateral.

DepegRisk
A situation where a stablecoin's market price deviates significantly from its target peg, typically by more than 0.5%.

Example

USDC depegged to $0.87 on March 11, 2023, following disclosure of $3.3B exposure to Silicon Valley Bank.

E-Money Token (EMT)Regulation
Under MiCA, a crypto-asset pegged to a single fiat currency. Issuers must be licensed e-money institutions or credit institutions in the EU.

Example

USDC EUR is classified as an EMT under MiCA; Circle holds an EU e-money license to issue it.

Fiat-Backed StablecoinTypes
A stablecoin whose value is maintained by holding fiat currency (or short-term equivalents like T-bills) in custody equal to or greater than circulating supply.

Example

Tether (USDT) is the largest fiat-backed stablecoin, claiming to hold primarily US Treasuries and cash equivalents.

Fractional ReserveMechanics
A banking practice where institutions hold only a fraction of deposits as liquid reserves. Some stablecoins have been accused of operating with fractional reserves.

Example

Under fractional reserve banking, a bank with $100 in deposits might hold $10 in reserves and lend out $90.

FSB (Financial Stability Board)Regulation
The G20-established international body that monitors and makes recommendations about the global financial system, including stablecoin regulation.

Example

The FSB published global standards for stablecoin oversight in 2020, which formed the basis for MiCA and other national frameworks.

GENIUS ActRegulation
The Guiding and Establishing National Innovation for US Stablecoins Act — US legislation establishing a federal framework for payment stablecoins.

Example

The GENIUS Act requires payment stablecoin issuers to maintain 1:1 reserves and obtain a federal or state license.

Hybrid StablecoinTypes
A stablecoin that combines multiple collateral types or stabilization mechanisms, such as both fiat reserves and algorithmic supply management.

Example

FRAX pioneered a hybrid model, partially collateralized by USDC and partially algorithmic, though it has since moved to full collateralization.

ISO 20022Technology
The international standard for financial messaging, increasingly adopted by SWIFT and central bank payment systems. Stablecoins designed for institutional use aim for ISO 20022 compatibility.

Example

Ripple's XRPL and several CBDC projects are building ISO 20022 compatible transaction formats to ease integration with traditional banking.

LiquidationRisk
The forced sale of collateral when its value falls below the minimum required level, used in crypto-collateralized stablecoin systems to maintain solvency.

Example

If a user has deposited $1,500 of ETH to mint $1,000 of DAI, and ETH's price falls enough to drop the collateral ratio below 150%, their position may be liquidated.

Liquidity PoolDeFi
A smart contract holding reserves of two or more assets that facilitates decentralized trading and lending without a traditional order book.

Example

The USDC/ETH pool on Uniswap allows users to swap between the two assets with fees paid to liquidity providers.

mBridgeProjects
A multi-central bank digital currency (CBDC) platform developed by the BIS Innovation Hub enabling direct cross-border settlements between participating central banks.

Example

mBridge allows participating central banks — including those of China, Hong Kong, UAE, and Thailand — to settle cross-border trades in seconds using wholesale CBDC.

MiCARegulation
Markets in Crypto-Assets Regulation — the European Union's comprehensive regulatory framework for crypto assets, including stablecoins, effective December 2024.

Example

Under MiCA, USDT was effectively delisted from EU exchanges in Q4 2024 as Tether had not obtained authorization.

MintMechanics
The process of creating new tokens, typically triggered when a user deposits collateral or fiat currency with a stablecoin issuer.

Example

When a user sends $1,000 to Circle and requests USDC, Circle mints 1,000 USDC and sends it to the user's wallet.

National Currency StablecoinTypes
A stablecoin pegged to a specific national currency other than the US Dollar, enabling digital payments in that currency on public blockchains.

Example

Circle's EURC is a Euro-pegged national currency stablecoin. Similar instruments exist for the Singapore Dollar (XSGD) and British Pound (GBPT).

Over-CollateralizationMechanics
Holding collateral worth more than the value of stablecoins issued, providing a buffer against collateral price declines.

Example

DAI typically requires 150–175% collateralization, meaning $1.50 of ETH must be locked for every $1 of DAI minted.

PegMechanics
The fixed exchange rate target a stablecoin aims to maintain against a reference asset, most commonly the US Dollar at 1:1.

Example

USDC maintains a $1 peg; any deviation triggers arbitrage — traders buy below $1 or sell above $1 to profit, restoring the peg.

Programmable MoneyTechnology
Digital currency that can execute code-defined conditions automatically, enabling use cases like escrow, conditional payments, and DeFi composability.

Example

A programmable stablecoin could automatically release payment to a supplier only when IoT sensors confirm goods have been received.

Proof of Reserve (PoR)Compliance
A cryptographic or audit-based method of verifying that a stablecoin issuer holds assets equal to its liabilities, making reserve verification transparent.

Example

Chainlink's Proof of Reserve service provides automated, on-chain verification of off-chain collateral for several stablecoins.

Real World Asset (RWA)Emerging
Tokenized representations of physical or traditional financial assets—real estate, bonds, receivables—on a blockchain.

Example

Ondo Finance tokenizes US Treasury bills, creating on-chain RWAs that earn yield while maintaining dollar-denominated value.

RedemptionMechanics
The process of exchanging stablecoin tokens for the underlying collateral or fiat currency from the issuer.

Example

Circle allows institutional clients to redeem USDC for USD bank transfers. Retail users typically sell on secondary markets.

ReserveMechanics
The assets held by a stablecoin issuer to back circulating tokens. Quality, liquidity, and transparency of reserves determine a stablecoin's trustworthiness.

Example

Tether's reserve includes US Treasury bills, reverse repos, money market funds, and a small percentage of 'other investments' including BTC.

SeigniorageEconomics
The profit from issuing currency — the difference between the currency's face value and the cost to produce it. Algorithmic stablecoins use seigniorage as their stability mechanism.

Example

In the Terra system, LUNA holders received seigniorage when UST demand grew — as new UST was minted, LUNA was burned, creating scarcity and value.

Smart ContractTechnology
Self-executing code deployed on a blockchain that automatically enforces the terms of an agreement without requiring a trusted intermediary.

Example

The DAI stablecoin is governed entirely by smart contracts — the MakerDAO protocol automatically liquidates under-collateralized positions.

Stablecoin TrilemmaEconomics
The theoretical impossibility of simultaneously achieving all three desirable stablecoin properties: price stability, capital efficiency, and decentralization.

Example

Fiat-backed stablecoins achieve stability and capital efficiency but sacrifice decentralization. DAI achieves decentralization and stability at the cost of capital efficiency.

SWIFTTraditional Finance
Society for Worldwide Interbank Financial Telecommunication — the messaging network used by banks for cross-border payment instructions. Stablecoins are often positioned as a faster, cheaper alternative.

Example

A SWIFT wire transfer from London to Tokyo takes 2–5 business days; the same transfer using USDC on-chain takes under 10 seconds.

Systemic RiskRisk
The risk that a failure in one part of the financial system cascades to other parts, potentially triggering a broader crisis.

Example

The 2022 Terra collapse demonstrated systemic risk — UST's failure triggered losses at Three Arrows Capital, Celsius, Voyager, and ultimately contributed to the broader crypto bear market.

TerraUSD (UST)History
The algorithmic stablecoin issued by Terraform Labs, pegged to the USD via the dual-token LUNA mechanism. Collapsed in May 2022.

Example

UST reached a market cap of $18.7 billion before its collapse to near-zero in May 2022.

TokenizationEmerging
The process of representing ownership of a real-world asset as a digital token on a blockchain.

Example

BlackRock's BUIDL fund tokenizes US Treasury shares on Ethereum, allowing institutions to hold T-bill exposure as on-chain tokens.

Travel RuleCompliance
A FATF requirement that obligates virtual asset service providers to share originator and beneficiary information for transfers above a threshold.

Example

Under MiCA and FATF guidance, a stablecoin transfer above €1,000 must include the sender's name, account number, and address in the transaction metadata.

USDCExamples
USD Coin — a regulated, US-dollar-backed stablecoin issued by Circle. Reserves consist entirely of cash and short-term US Treasuries.

Example

USDC is MiCA-compliant and used as the primary stablecoin on Coinbase's Base blockchain.

USDT (Tether)Examples
The world's largest stablecoin by market cap, issued by Tether Limited. Has faced scrutiny over reserve transparency and quality.

Example

With ~$120B in circulation, USDT accounts for over 60% of the total stablecoin market cap.

Wholesale CBDCDigital Money
A digital central bank currency designed for use by financial institutions (banks, settlement systems) rather than the general public.

Example

Project mBridge uses wholesale CBDC to settle interbank claims between participating central banks in real time, eliminating correspondent banking delays.
