Stablecoin Types and Examples: A Practical List

Stablecoins are crypto tokens designed to track a reference value, usually one U.S. dollar. They are used for trading, transfers, savings products, and DeFi, but “stable” describes a design goal—not a promise that the market price cannot move. A token may trade above or below its target, and holders may not all have the same ability to redeem it.

The main types are classified by how they support that target:

• Fiat-backed: an issuer holds cash-like reserves and offers redemption under its terms.
• Crypto-backed: a protocol locks crypto collateral, often worth more than the stablecoins it creates.
• Commodity-backed: tokens represent claims linked to assets such as gold.
• Synthetic or hedged: financial positions or other mechanisms aim to track a currency without relying on a conventional cash reserve for each token.
• Algorithmic: rules adjust supply or incentives to defend a peg, sometimes with limited or no external collateral.

These categories can overlap. A token can use crypto collateral and governance mechanisms, for example, while a dollar-tracking token can also offer a separate yield-bearing version. Later sections compare well-known examples and explain what to check before using one. None should be treated as risk-free cash or as a bank deposit unless its legal terms specifically support that understanding.

Fiat-backed stablecoins are issued by a company or other organization that says it holds reserves to support tokens in circulation. Reserves may include cash, bank deposits, short-term government securities, or other assets, depending on the issuer. The issuer’s redemption policy, access requirements, and reserve disclosures matter as much as the advertised peg.

Common examples include Tether’s USDT and Circle’s USDC, both designed to track the U.S. dollar. PayPal USD (PYUSD) is another dollar-pegged token issued by Paxos. These are examples, not a ranking or an assurance that each is available in every country or on every network.

Before holding one, check:

1. Who issues it and which entity is responsible for redemption.
2. What assets back it, and how often reserve information is published.
3. Whether redemption is available to you, including minimums and eligibility rules.
4. Which blockchain and token contract you are using.

A reserve report is not necessarily the same as a full audit, and a token in a self-custody wallet does not automatically give every holder direct redemption rights. The issuer may also freeze tokens under its terms. Fiat backing can make a token’s mechanism easier to understand than some alternatives, but it still carries issuer, banking, regulatory, custody, and market-liquidity risks.

Crypto-backed stablecoins use digital assets as collateral. Because crypto prices can fall quickly, systems commonly require collateral worth more than the stablecoins issued against it. If collateral values fall too far, smart contracts or other mechanisms may liquidate positions to help cover the debt. Price oracles, liquidation incentives, and the market depth of the collateral all affect how well this process works during stress.

DAI and USDS are stablecoins associated with Sky, formerly MakerDAO. Their system uses collateral and protocol rules, rather than depending solely on a conventional company holding cash reserves. Sky’s ecosystem also includes sUSDS, a separate savings token that can provide a return under the protocol’s rules; that return is not guaranteed. BOLD, issued through Liquity V2, is another example: users can borrow it against supported crypto collateral, including ETH-related assets.

These examples do not all use identical collateral, borrowing, or governance arrangements. Read the current protocol documentation before depositing assets or relying on a redemption mechanism. Risks can include collateral depegging, oracle errors, liquidations, smart-contract bugs, governance changes, and a stablecoin trading below its target when demand or confidence falls. Overcollateralization is a buffer, not a guarantee. If you use a decentralized exchange such as Curve to swap stablecoins, also consider pool liquidity and whether the particular asset is temporarily off its peg.

Commodity-backed tokens aim to track the value of a physical asset, most often gold. Their price can move with the commodity rather than remain near one U.S. dollar, so they are asset-backed tokens but not necessarily dollar stablecoins. They may suit someone seeking blockchain-based exposure to a commodity, but that is a different use from keeping a dollar-equivalent balance for payments or trading.

PAX Gold (PAXG) and Tether Gold (XAUT) are familiar gold-token examples. Each has its own issuer, custody structure, terms, and processes for verifying backing or seeking redemption. Do not assume that holding a token gives you the same practical rights as possessing a gold bar. Redemption may have eligibility conditions, minimum quantities, fees, or delivery limitations; read the current terms rather than inferring rights from the token name.

Commodity tokens also have risks that dollar stablecoins do not share in the same way. Gold prices fluctuate, and a token’s market price can differ from the value of the underlying metal. Holders depend on the issuer and custodian, and may face legal, operational, and market-liquidity risks. A token’s reserves and redemption arrangements should be checked directly with its issuer. If your priority is a stable dollar price, a gold-backed token is not a substitute just because it is described as backed by an asset.

Synthetic or hedged dollar tokens aim to maintain a dollar-like value through financial positions, collateral, or a combination of mechanisms. They are not automatically backed by a bank account holding one dollar for every token, so their risks differ from those of a conventional fiat-backed stablecoin.

Ethena USDe is a prominent example of a synthetic dollar design. Its mechanism uses crypto assets and hedging positions, including short derivatives positions, rather than being a straightforward cash-reserve token. This creates exposure to the operation of the hedges, the venues and counterparties involved, collateral custody, funding conditions, and the ability to manage positions during volatile markets. The exact structure and risk controls can change, so check current project disclosures.

The word “synthetic” is sometimes used loosely. It does not by itself tell you whether a token is overcollateralized, whether holders can redeem directly, or what happens if a hedge fails. Compare the actual mechanism, not just the label. Ask what backs the token, where those assets or positions are held, how the peg is maintained, and what losses holders could face under stress. A synthetic token can trade close to a dollar for long periods and still carry risks that are not present in the same form for a cash-backed token.

Algorithmic stablecoins rely substantially on software rules, supply adjustments, incentives, or linked tokens to keep a target price. Some designs also hold collateral, so “algorithmic” and “collateralized” are not always mutually exclusive labels. The key question is whether there are assets with credible value behind the token and whether holders have a workable way to redeem or exit when demand falls.

The collapse of TerraUSD (UST) is a cautionary example. Its mechanism depended heavily on a relationship with the LUNA token. When confidence and market conditions deteriorated, the design failed to maintain its dollar target, demonstrating how a feedback loop can intensify losses rather than restore the peg. UST is a historical example, not a stablecoin to treat as a current dollar equivalent.

A token may also describe itself as “algorithmic” while holding some reserves or using multiple mechanisms. Evaluate the specifics: the quality and liquidity of collateral, whether redemptions depend on another volatile token, and how the system behaves when many holders try to exit at once. A target price and automated rules do not create a guarantee of solvency. If the project’s mechanism is difficult to explain in plain language, or its reserve and redemption information is unavailable, treat that uncertainty as a material risk rather than assuming the peg will hold.

Yield-bearing stablecoins combine a stable-value target with a return mechanism, or they offer a separate token that accrues yield against a stablecoin. It is important to distinguish the underlying stablecoin from a deposit, receipt, or savings token. The second token may represent a claim on a protocol position, and its value or redemption terms can differ from those of the underlying asset.

For example, USDS is a dollar stablecoin associated with Sky, while sUSDS is a savings token within the same ecosystem. The latter’s return depends on protocol parameters and does not turn it into a bank deposit or a guaranteed-interest product. Other yield strategies may involve lending, staking, Treasury exposure, or hedging, each with distinct legal and technical risks.

Before choosing a yield-bearing product, identify where the return comes from. Is it paid by borrowers, generated by a protocol, linked to market rates, or supported by token incentives? Check whether the rate can change, whether withdrawals can be delayed, and whether the token can lose its peg. Additional risks may include smart-contract vulnerabilities, custodians, counterparties, and changing rules. A displayed rate is not a promise of future income, and higher advertised returns can reflect higher or less obvious risks. Compare the product’s terms with simply holding its underlying stablecoin.

No stablecoin type is best for every purpose. A useful comparison starts with how the token maintains its target and what you need to do with it. A token may have deep trading liquidity but limited direct redemption for an individual; another may be decentralized but rely on volatile collateral and protocol governance.

Type	Example	What to check
Fiat-backed dollar	USDT, USDC, PYUSD	Issuer, reserves, redemption terms, freezes
Crypto-backed dollar	DAI, USDS, BOLD	Collateral, liquidation rules, oracles, governance
Commodity-backed	PAXG, XAUT	Commodity price, custody, redemption conditions
Synthetic or hedged dollar	USDe	Hedge structure, counterparties, collateral, exits
Algorithmic design	TerraUSD (UST), historical	Reliance on incentives or linked tokens; failure history
Yield-bearing version	sUSDS	Source of yield, variable rates, withdrawal and contract risk

These labels describe broad mechanisms, not safety scores. Even two tokens in the same category can differ sharply in transparency, liquidity, network support, and user rights. A stablecoin’s current market price, circulating supply, and available trading depth change over time. Check those in a current market interface, and use the issuer or protocol’s own documentation for reserves, collateral, and redemption details. Do not infer that similar tickers or names mean two tokens are interchangeable.

Start with the job the token needs to do. For a payment or transfer, consider whether the recipient supports the exact stablecoin and network, the transaction cost, and whether the issuer can freeze or block tokens. For DeFi, check the pool or lending market’s supported contract, liquidity, collateral rules, and liquidation terms. Protocols such as Aave V3 and SparkLend can support stablecoin lending markets, but depositing a token introduces smart-contract and market risks beyond simply holding it.

Use this checklist before sending or depositing funds:

1. Verify the asset. Confirm the issuer or protocol and the exact token contract; names and tickers can be copied.
2. Verify the network. The same stablecoin may exist on multiple chains. Sending to an unsupported network can make funds difficult or impossible to recover.
3. Read the mechanism. Identify the backing, redemption route, and what could interrupt either one.
4. Check the price and liquidity. A peg can weaken, and a thin market can make a large swap costly.
5. Protect access. Use secure wallet practices and understand that self-custody also means responsibility for keys and transactions.

A DEX such as Uniswap can provide swaps, but it does not guarantee a token’s peg or the quality of its reserves. Avoid relying on a single label such as “fully backed.” Read current disclosures, consider your local rules, and only use products whose risks and redemption terms you understand.
