What Types of Stablecoins Are There? Four Categories, Examples, and How to Choose
Stablecoins are commonly grouped by what supports their price: fiat or liquid reserves, crypto collateral, algorithmic mechanisms, or commodities. Choosing among them requires checking the peg, reserves or collateral, redemption, liquidity, networks, and regulation.
For the basic concept, read what stablecoins are. For USDT, USDC, and DAI/USDS, see our dollar stablecoin comparison.
Four main types of stablecoins
| Type | Examples | Support mechanism | Key risks |
|---|---|---|---|
| Fiat or liquid-reserve backed | USDT, USDC, PYUSD, USA₮ | Issuer-managed reserve assets | Issuer, reserve, redemption, regulation |
| Crypto-collateralized | DAI, USDS, LUSD | On-chain collateral and liquidation | Collateral decline, liquidation, governance, smart contracts |
| Algorithmic | UST as a failed historical example | Supply or token incentives | Confidence collapse and death spiral |
| Commodity-linked | PAXG, XAUT | Commodity or related claims | Commodity price, custody, redemption, issuer |
Fiat or liquid-reserve-backed stablecoins
These tokens are issued against cash, short-term government securities, or other liquid assets. Examples include USDT, USDC, PYUSD, and USA₮.
- USDT: widely supported across exchanges and networks; review Tether’s latest reserves and redemption terms. See what USDT is.
- USDC: Circle publishes reserve and third-party assurance information; direct Circle Mint redemption is mainly for eligible institutions.
- USA₮: issued by Anchorage Digital Bank in collaboration with Tether and should not be treated as the same product as USDT.
BUSD is a useful historical case because new issuance stopped.
Crypto-collateralized stablecoins
These systems use on-chain collateral, often with overcollateralization, liquidation, and governance rules. DAI and USDS are part of the Sky Protocol ecosystem; Sky describes USDS as an upgraded version of DAI. Current collateral and conversion rules should be checked before use.
Algorithmic stablecoins
Algorithmic designs rely heavily on supply, arbitrage, or another token. The collapse of UST showed how quickly the mechanism can fail when confidence and liquidity disappear. Hybrid products such as FRAX should be classified using their current design rather than an old label.
Commodity-linked stablecoins
PAXG and XAUT track gold rather than one dollar. Their prices move with gold, and users must also review custody, redemption units, and issuer terms.
How should stablecoin rankings be read?
- Market cap shows scale, not guaranteed safety.
- Trading volume and depth affect slippage.
- Price deviations reveal pressure on the peg.
- Reserve or collateral quality and redemption rules shape risk.
- Network and platform support affect actual cost and usability.
Six checks before choosing a stablecoin

Also review stablecoin reserve evidence and depegging risk.
