A stablecoin is a cryptocurrency designed to maintain a stable value by being pegged to traditional assets like the U.S. dollar, euro, or gold. Unlike Bitcoin, which can fluctuate dramatically, stablecoins aim to combine the benefits of digital currency with price stability.
When people ask “what is a stablecoin,” the simplest answer is: it’s a digital version of traditional money that lives on the blockchain. Think of stablecoins as the bridge between volatile cryptocurrencies and stable fiat currencies. Need a refresher on what is decentralized finance? Check out our recent article here.
How Do Stablecoins Work?
Stablecoins maintain their stability through different backing mechanisms. Understanding what is a stablecoin means knowing these four main types:
Fiat-Backed Stablecoins
- What they are: Backed 1:1 by traditional currencies like USD
- Examples: USDC, USDT (Tether)
- How they work: For every stablecoin issued, one dollar is held in reserve
Crypto-Backed Stablecoins
- What they are: Backed by other cryptocurrencies (overcollateralized)
- Examples: DAI
- How they work: Use excess crypto collateral to maintain the peg
Algorithmic Stablecoins
- What they are: Use smart contracts and algorithms to control supply
- Examples: FRAX (note: Terra’s UST famously failed)
- How they work: Automatically mint or burn tokens to maintain price
Commodity-Backed Stablecoins
- What they are: Pegged to physical assets like gold
- Examples: PAXG
- How they work: Each token represents ownership of real-world commodities
Why Stablecoins Matter for Digital Payments
Stablecoins solve a critical problem in cryptocurrency: price volatility. Here’s why they’re becoming essential for digital commerce:
Key Benefits of Stablecoins

Real-World Stablecoin Use Cases
