Types of stablecoins

The GENIUS Act was signed by the President of the United States on July 18, 2025. MiCA is live in Europe. BlackRock is issuing tokenized money market funds. The stablecoin market sits at $300B+ in total market cap. For fintech builders, product teams, and business strategists, it has become essential to understand the different stablecoin models and their functionalities.

If you want to go deeper on the regulatory side, we've covered how stablecoin regulation works in a separate guide.

This guide covers all 8 major types: what they are, how they work, where they've broken, and what trade-offs come with each.

‍

What is a stablecoin?

Stablecoins are a type of crypto-asset (tokens on a blockchain) designed to keep a stable price. The name comes from the word "stable," which is exactly what they are meant to be.

Classic cryptocurrencies—like Bitcoin, Ethereum, and Solana—set their price only through supply and demand.

Stablecoins work differently: they are built by design to keep a fixed value compared to a specific asset. This "anchor" can be:

• The US Dollar
• The Euro
• Gold
• A mix of different assets

A simple example: If a stablecoin is linked to the dollar, its price should always stay at about $1.

How stablecoins maintain their peg

For a coin to be called a stablecoin, it must have a "stabilization mechanism"—a way to keep its value steady. The main ways to do this are:

• Real-world reserves (Fiat-backed): Backed 1-to-1 by traditional money like the US Dollar.
• Crypto collateral: Backed by other cryptocurrencies as security.
• Algorithmic models: Using code and math to automatically balance the supply.
• Financial/Synthetic strategies: Using complex trading tactics to stay stable.
• RWA-backed: Backed by "Real World Assets," such as Treasury bills or real estate.

Why companies launch their own stablecoins

The stablecoin market has become a vital part of the world’s financial infrastructure.

The USD-denominated segment now exceeds $225 billion in market cap, with yearly transaction volumes hitting $33 trillion. This growth continues even when the rest of the crypto market is volatile.

The main driver: payments

The biggest reason for this shift is how money moves.

• Traditional Banks: International payments take 3–5 business days and cost 3–5% in fees.
• Stablecoins: Transfers happen in minutes, 24/7, with very low fees.

For global SaaS companies, online marketplaces, and fintech companies, this means direct savings and faster access to their money.

Major players joining in

Because of these benefits, giants like PayPal, Stripe, and Meta are actively building their own solutions. A great example is Payoneer, which recently announced it is adding stablecoin features using Stripe’s "Bridge" infrastructure.

This allows businesses to:

• Accept payments in stablecoins.
• Hold funds in digital dollars.
• Withdraw to a bank account only when needed.

For many businesses, the question is no longer "What is a stablecoin?" but rather "How can we make it part of our payment system?"

The next frontier: stablecoins + AI agents

One of the most significant long-term drivers of stablecoin adoption is one that has nothing to do with human payments: autonomous AI agents conducting economic activity at machine speed.

As Jeremy Allaire (Circle CEO) argued at WEF 2026, we are heading toward a world where billions of AI agents conduct economic transactions continuously — purchasing compute, consuming APIs, settling contracts, trading data. These agents cannot use a credit card or initiate a bank wire for a $0.003 micropayment. They need a payment medium that operates at the speed of the internet, scales down to fractions of a cent, works globally without geographic or institutional restrictions, and provides cryptographically verifiable transaction finality.

Stablecoins — particularly programmable, on-chain dollar instruments — are the only payment infrastructure that meets these requirements today. New blockchain networks are being specifically engineered for “agentic compute,” designed to handle the financial and economic activity of an AI-native economy. Stripe and Shopify have already integrated USDC payment acceptance. Visa and Mastercard use USDC as internal settlement infrastructure. The foundation is being laid now for a payment system that will, in three to five years, need to process transactions between machines at a scale no legacy system was designed to handle.

8 Types of stablecoins

1 Fiat-backed stablecoins

Fiat-backed stablecoins are coins whose price is supported by a full supply of traditional currency.

To put it simply: For every token created, there is a real dollar, euro, or other currency held in the issuer's reserves. In this model, stability is achieved in the most direct way: real money kept in a bank or in government treasury bonds.

Examples: USDT (Tether), USDC (Circle), PYUSD (PayPal), EURC (Circle), EURS (Stasis Euro), GYEN, XCHF.

Pros

• Maximum price stability — the gold standard for payment use cases.
• Explicitly addressed by US GENIUS Act as "payment stablecoins".
• High Liquidity & Availability: As the most common type of stablecoin, they are widely accepted across almost all exchanges, DeFi protocols, and trading platforms.
• Transparency and Trust: Reputable issuers provide regular, often monthly, audits and attestations of their reserve assets (cash, U.S. Treasury bills), allowing users to verify backing.
• Financial Inclusion & Access: They offer individuals in countries with unstable fiat currencies access to dollar-like stability without needing a U.S. bank account.

Cons

• Fully centralized — issuers can freeze or blacklist addresses.
• Counterparty and Bank Risk: The reserves are usually held in commercial banks. If the bank fails or freezes assets, the stablecoin can de-peg and lose value.
• Dependent on regular audits and proof-of-reserves disclosures.
• KYC/AML Compliance Pressure: These tokens are subject to strict "Know Your Customer" and "Anti-Money Laundering" regulations, limiting anonymity.

2 Crypto-backed stablecoins

Crypto-backed stablecoins are coins secured by other cryptocurrencies rather than traditional money (fiat).

While the fiat-backed model relies on a dollar sitting in a bank, this model relies on crypto assets locked in a smart contract.

How the Mechanics Work:

1. The User locks up a cryptocurrency (like Ethereum or Bitcoin) inside a smart contract.
2. The Smart Contract then creates (mints) the stablecoin.
3. The Collateral is kept on-chain (on the network) and managed automatically by code.

Why "Extra Backing" (Overcollateralization) is Needed

Cryptocurrencies are volatile, meaning their prices can drop suddenly. To stay safe, these systems use overcollateralization:

• $100 of stablecoins are issued.
• $150–$200 of crypto assets are held as security.
• This provides 150–200% coverage.

If the price of the security drops too far:

• The position is automatically sold off (liquidated).
• The assets are used to cover the value.
• The system protects the stablecoin’s price.

This automatic "sell-off" is the key protection mechanism that keeps the coin stable even when the market is crashing.

Examples: DAI (MakerDAO), LUSD (Liquity), sUSD (Synthetix), crvUSD (Curve)

Pros

• Decentralization and Censorship Resistance: Unlike fiat-backed stablecoins, these are not reliant on bank accounts or custodians, making them harder to seize or freeze.
• Fully on-chain transparency — all reserves verifiable in real time.
• DeFi Interoperability: They are designed for the decentralized finance (DeFi) ecosystem, serving as a reliable unit of account for lending, borrowing, and liquidity provision.
• High Capital Efficiency: Users can maintain exposure to crypto assets while using them as collateral to generate liquidity.

Cons

• Capital-inefficient — requires locking more value than you borrow.
• Volatility and Liquidation Risk: Because the underlying collateral is crypto (ETH, WBTC), a sharp market drop can lead to automatic liquidations of user positions to maintain the peg.
• De-pegging Risk: In extreme market crashes, the liquidation engine might fail to keep up with the price drop, causing the stablecoin to lose its $1 peg.

3 Commodity-Backed

Commodity-backed stablecoins are digital tokens on a blockchain pegged to physical assets like gold, silver, oil, or real estate, providing intrinsic value and inflation protection. Primarily backed by gold, these tokens allow for fractional ownership and redemption for the underlying physical asset, typically stored in secure, audited vaults.

Examples: PAXG (Paxos Gold), XAUT (Tether Gold), DGLD

Pros

• Portfolio Diversification: They provide a way to diversify crypto portfolios, allowing users to move funds into safer, tangible assets during high market volatility.
• Inflation Hedge & Stability: Unlike fiat-backed stablecoins that depend on central bank policy, these tokens are backed by hard assets (gold, silver, oil), providing a superior hedge against inflation and currency devaluation.
• Fractional Ownership & Accessibility: They enable users to own small fractions of high-value commodities (e.g.$10 worth of gold) without needing to manage physical storage, insurance, or security logistics.
• On-Chain Liquidity & DeFi Utility: These tokens can be used as collateral in decentralized finance (DeFi) lending protocols, allowing investors to gain liquidity against their assets without selling the underlying commodity.

Cons

• Centralization & Counterparty Risk: These tokens depend on a central custodian to hold the physical asset, meaning a hack, bankruptcy, or seizure of the storage facility could lead to a total loss of value.
• Physical Storage & Audit Complexity: Unlike digital or fiat, physical commodities require secure, audited storage, insurance, and complex, often delayed, verification processes.
• Price Volatility: Unlike fiat-backed coins, commodity-backed tokens are not pegged to a stable dollar value; they fluctuate with the spot price of the commodity (e.g., gold price drops), which can cause loss of purchasing power.
• Regulatory Uncertainty: They must comply with both digital asset regulations and traditional commodity trading regulations, which are complex and vary by jurisdiction.

4 Algorithmic stablecoins

Algorithmic stablecoins are "stable" coins that try to stay at $1 using only smart code and incentives — no real dollars or big crypto piles as backup. The $1 peg typically refers to the US dollar, which is the most common target for stablecoin issuers. The system automatically creates or burns tokens to balance supply and demand. Famous example: Terra's UST, which famously collapsed in 2022 in a huge “death spiral”. Most are super risky and lost trust after that crash — in 2026, pure ones are rare and not popular. Hybrids (part algo + part collateral) are safer but still experimental.

Examples: AMPL (Ampleforth), UST/LUNA (collapsed May 2022), FRAX (partial algorithmic component)

UST/LUNA: what actually happened

May 2022. TerraUSD (UST), then an $18B stablecoin, lost its peg in what appeared to start with coordinated large-scale selling. The dual-token mechanism kicked in — the protocol minted massive amounts of LUNA to absorb selling pressure. LUNA got flooded. LUNA price crashed. Which made UST's backing weaker.

LUNA lost 96% of its value in a single day. The Terra ecosystem lost approximately $40B total. It directly influenced MiCA's decision to exclude algorithmic stablecoins from the regulatory category.

Pros

• Highly capital-efficient — no 1:1 or 150% collateral requirement
• Fully decentralized in pure implementations
• Theoretically unlimited scalability

Cons

• Death Spiral Risk: If market confidence drops, the algorithm may trigger a feedback loop where selling pressure forces more selling, reducing the token’s value toward zero, as seen with TerraUSD (UST).
• De-pegging Vulnerability: Unlike asset-backed coins, algorithmic coins rely on market incentives to maintain parity. High volatility or bank-run scenarios can cause them to lose their $1 peg, as experienced by Ethena's USDe and UST.
• High Complexity and Governance Risk: These systems are technologically complex, creating risks for smart contract failures or flaws in the economic design.

5 Hybrid stablecoins

Hybrid stablecoins are coins that use several stabilization methods at once. They don't rely on just one source of backing. Instead, they combine:

• Fiat (traditional money)
• Crypto collateral (digital assets)
• RWA (Real-World Assets like Treasury bills)
• Algorithmic tools (math-based supply control)

The idea is simple: don't put all your eggs in one basket.

Examples: FRAX (algorithmic + USDC collateral), GHO (Aave protocol-backed), crvUSD (Curve's LLAMMA mechanism)

Pros

• Enhanced Stability: By combining collateral backing with algorithmic adjustments, these tokens provide a more robust peg to their target asset (e.g., US dollar) than purely algorithmic counterparts.
• Capital Efficiency: Because they are not always required to be 100% collateralized, they can be more capital-efficient than traditional, fully backed stablecoins.
• Automatic Algorithmic Adjustments: They use algorithms and smart contracts to manage supply and demand, allowing for rapid stabilization in response to market volatility.

Cons

• High Technical and Conceptual Complexity: Hybrid models combine multiple mechanisms (e.g., collateralization + delta-neutral hedging), making them difficult for users to fully understand and evaluate.
• Liquidity and Redemption Challenges: During times of market stress, redeeming hybrid stablecoins for fiat can be more difficult than with traditional, fully backed, fiat-collateralized coins.
• Regulatory Uncertainty: As a newer, more complex class of assets, hybrid stablecoins may face stricter regulatory scrutiny or, as the EU's MiCA framework suggests, forced adjustments to their design.

6 RWA-Backed (Real-World Assets)

RWA-backed stablecoins are a type of digital asset where the price stays stable because it is backed by tokenized investments from the traditional financial world. Instead of just keeping cash in a bank, the issuer holds high-quality assets like U.S. Treasury bonds, money market funds, or other secure financial instruments.

These assets are "tokenized," meaning they are turned into digital versions that live on the blockchain.

Because the underlying assets (like government bonds) earn interest in the real world, these stablecoins can often pass that profit back to the holders automatically. This makes them work like a "digital deposit" or a "blockchain savings account"—offering both price stability and a way to grow your funds.

Examples: USYC (Circle/Hashnote), USDY (Ondo Finance), BUIDL (BlackRock), RLUSD (Ripple)

Pros

• Higher Stability & Security: Unlike crypto-collateralized options, RWA stablecoins are backed by tangible assets, reducing risk during market downturns.
• Yield Generation: Holders can directly earn income from underlying, yield-bearing assets (e.g., tokenized U.S. Treasuries).
• Regulatory Alignment: These stablecoins are generally more compatible with legal and compliance frameworks.
• Access to Traditional Finance (TradFi): They provide crypto-native investors with exposure to real-world markets like commodities or real estate.

Cons

• Regulatory Uncertainty & Fragmentation: Operating globally is difficult due to varying, evolving legal frameworks regarding securities and banking laws.
• Asset Volatility & Default Risk: If the real-world assets (e.g., real estate, loans) decline in value, the stablecoin can depeg. There is also a risk of underlying asset defaults.
• Custodial & Operational Risks: Managing keys and securing physical assets (gold, real estate) presents significant technical, custodial, and audit challenges.
• Access Restrictions: Some RWA tokens are restricted to whitelisted investors or specific regions, limiting accessibility.

7 Synthetic stablecoins

Synthetic stablecoins (often called synthetic dollars) are a type of stablecoin that maintains a price of $\approx \$1$ without direct dollar deposits in a bank or massive crypto collateral like DAI. Instead, they use financial "tricks" (delta-neutral strategies, hedging, futures) on crypto markets to "synthesize" a stable dollar.

The process looks like this: you take ETH (or BTC), stake it (to generate yield), and then open an equivalent short position on ETH futures.

• If ETH goes up: you lose on the short but gain from the staking value.
• If ETH goes down: you profit from the short but lose on the staking value.

As a result, the fluctuations balance each other out (delta-neutral), and the position’s value stays at $\approx \$1$.

It’s essentially a "self-balancing" dollar that exists purely on crypto markets and generates yield (from funding rates and staking rewards).

Examples: USDe (Ethena) — delta-neutral ETH/BTC hedging via perpetual futures

Pros

• High Capital Efficiency: They often use over-collateralization or hedging strategies (delta-neutral) to create stable value without needing a 1:1 reserve of traditional fiat currency.
• Yield Generation: They can offer attractive yields derived from on-chain mechanisms like liquid staking or hedging fees, attracting investors looking for higher returns than traditional stablecoins.
• Asset Exposure (Synthetic Tokens): They allow users to gain exposure to real-world assets (commodities, forex, stocks) directly on-chain without directly owning the underlying asset.

Cons

• Peg stability depends on sustained futures market liquidity
• Negative funding rate environments can compress or eliminate yield
• Liquidity and Redemption Challenges: During a bank run or market shock, synthetic stablecoins can suffer from liquidity crises, making it difficult for users to redeem their tokens for the underlying value.

8 Yield-Bearing

Yield-bearing stablecoins are digital assets that generate passive income for holders through underlying reserve investments like U.S. Treasuries, DeFi lending, or staking.

Examples: sUSDC, USYC-style tokens, tokenized money market fund shares (BlackRock BUIDL, Franklin OnChain)

Pros

• Passive Income Generation: Investors earn yield without having to actively manage or lock up assets in separate, complex DeFi protocols.
• DeFi Integration: They are highly composable, allowing for easy use within lending, borrowing, and liquidity pools.
• Enhanced Yield Opportunities: Certain, such as Ethena's USDe, can offer high APYs (sometimes 7–19%) through strategies like delta-neutral funding rates.

Cons

• Heightened Risk and Depegging: Unlike 1:1 backed stablecoins, the mechanisms generating yield can fail, causing the token to lose its $1 peg.
• No Deposit Insurance/Regulatory Issues: These instruments often lack deposit insurance and are subject to, or may soon be, strict regulatory scrutiny, with some jurisdictions (like the EU) prohibiting yield on payment stablecoins.
• Liquidity and "Run" Risk: In times of market stress, these stablecoins can suffer from "runs" if investors simultaneously attempt to redeem, causing potential redemption freezes.
