## What Are Stablecoins and Why Do They Matter?
Stablecoins are cryptocurrencies designed to maintain a stable value by pegging to external assets like fiat currencies (e.g., the U.S. dollar) or commodities. They bridge the volatility gap between traditional finance and crypto, enabling seamless trading, remittances, and decentralized finance (DeFi) participation. Among the dozens of stablecoins, **Tether (USDT)** and **USD Coin (USDC)** dominate the market, collectively holding over $100 billion in circulation. But what sets them apart?
## Tether (USDT): The First-Mover Stablecoin
Launched in 2014, USDT is the oldest and most widely used stablecoin, with a market cap exceeding $95 billion. Operated by Tether Limited (affiliated with crypto exchange Bitfinex), USDT aims to maintain a 1:1 peg to the U.S. dollar.
### How USDT Works
– **Backing**: Tether claims USDT is backed by reserves including cash, cash equivalents, and other assets. However, its transparency has been questioned historically.
– **Use Cases**: Dominates trading pairs on exchanges like Binance; widely used in DeFi protocols.
– **Pros**: High liquidity, broad acceptance, and multi-chain support (ERC-20, TRC-20, etc.).
– **Cons**: Limited transparency until 2021, when Tether began publishing quarterly reserve reports.
## USD Coin (USDC): The Regulated Challenger
Introduced in 2018 by Circle and Coinbase, USDC has grown rapidly to become the second-largest stablecoin, with a market cap of over $32 billion. It’s known for regulatory compliance and transparency.
### How USDC Works
– **Backing**: Fully backed by cash and short-term U.S. Treasuries, attested monthly by accounting firm Deloitte.
– **Use Cases**: Preferred for institutional transactions, cross-border payments, and compliant DeFi projects.
– **Pros**: High transparency, regulatory oversight, and growing adoption in traditional finance.
– **Cons**: Slightly lower liquidity than USDT on some exchanges.
