Preface

In today’s highly volatile and fast-paced crypto market, stablecoins are a safe haven for traders, institutions, DeFi protocols, and everyday users. They offer a stable store of value amid rapid market shifts. From leveraged trading and liquidity mining to cross-chain transfers, stablecoins are the backbone and foundational unit of daily crypto transactions.

What Are Stablecoins?

Stablecoins are cryptocurrencies pegged to stable assets like the US dollar or gold. They are designed to provide price stability on the blockchain. Depending on their issuance method and collateral structure, stablecoins fall into three categories:

1. Fiat-Collateralized

Backed by real-world assets (e.g., USD) and managed by a centralized entity.

• Advantages: High stability, clear and direct price anchoring
• Risks: Requires trust in the issuer; higher regulatory risk

2. Crypto-Collateralized

Overcollateralized with crypto assets (such as ETH) and issued via smart contracts.

• Advantages: Highly decentralized
• Risks: Collateral asset price volatility can trigger liquidations

3. Algorithmic

Maintains price stability through liquidity dynamics and burn mechanism, without any physical or crypto collateral.

• Advantages: Fully decentralized, experimental, and innovative
• Risks: Most previous projects have not succeeded or are no longer active

Major Global Stablecoins

1. USDT (Tether)

• Type: Fiat-collateralized
• Issuer: Tether Ltd.
• Stabilization Mechanism: 1:1 peg to the US dollar
• Key Features: Largest market capitalization, highest liquidity
• Use Cases: CEX trading, on-chain transfers, collateral for margin trades

2. USDC (USD Coin)

• Type: Fiat-collateralized
• Issuer: Backed by Circle and Coinbase
• Stabilization Mechanism: Fully backed by US Treasury bills, cash, and equivalents
• Key Features: Strong regulatory compliance, preferred by businesses and financial institutions
• Use Cases: Business payments, DeFi payments, and stable pools for trading pairs

3. DAI

• Type: Crypto-collateralized
• Issuer: MakerDAO (fully decentralized protocol)
• Stabilization Mechanism: Created through overcollateralization with ETH and other assets
• Key Features: The first prominent decentralized stablecoin
• Use Cases: DeFi lending, yield pools, collateral for margin trades

Stablecoin Use Cases and Value

1. Decentralized Finance (DeFi)
   Most DeFi protocols—including lending platforms, DEXs, and liquidity pools—rely on stablecoins for pricing and settlement, which enables accurate price benchmarks and risk management.
2. International Transfers and Payments
   Compared to traditional banks, cross-border transactions using USDT or USDC offer faster speed and significantly lower fees. Settlements occur in real time without being limited by banking hours.
3. Safe-Haven Crypto Asset
   During periods of intense market volatility, converting holdings into stablecoins provides a hedge against risk and serves as a safe haven for major market participants.
4. Financial Infrastructure in Emerging Markets
   In countries experiencing hyperinflation or unstable local currencies, stablecoins offer a reliable alternative for daily savings and transactions, preserving value amid economic uncertainty.

Potential Risks of Stablecoins

While stablecoins deliver convenience and stability, it’s crucial to watch for these risks:

• Reserve Audit Issues: Tether has faced scrutiny over whether its dollar reserves are adequate
• Regulatory Risk: U.S. and European regulators are increasingly tightening stablecoin oversight
• Varied Decentralization: Some stablecoins are vulnerable to asset freezes or censorship controls
• Depegging Risk: Especially for algorithmic stablecoins, which are more susceptible to losing their peg

Future Trends in Stablecoin Development

As blockchain technology continues to mature and regulatory clarity emerges, stablecoins are on track for several clear evolutionary paths. Central bank digital currencies (CBDCs), led by national central banks, are expected to coexist with traditional stablecoins and could reshape their market roles. Meanwhile, DeFi-native, decentralized stablecoins—like GHO and crvUSD—are gaining ground thanks to greater trustlessness and composability. The rise of cross-chain and Layer 2 technologies is enhancing stablecoin usability and interoperability, particularly against the backdrop of rapid advances in rollups and modular blockchain ecosystems.

Stablecoins backed by real-world assets (RWAs) are also gaining momentum. In the future, we may see diversified stablecoins pegged to other currencies or commodities such as gold. Stablecoins will represent more than just digital dollars—they will form a foundational element of Web3 financial infrastructure.
