1. What is a Stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value, typically pegged to a fiat currency such as the US Dollar (USD). Unlike Bitcoin or Ethereum, whose prices fluctuate significantly, stablecoins aim to maintain a stable value around $1 USD.
2. Types of USD 1 Stablecoins
| Stablecoin | Type | Issuer | Notes |
|---|---|---|---|
| USDT (Tether) | Fiat-collateralized | Tether Ltd | One of the oldest and most widely used; backed by USD reserves and other assets. |
| USDC (USD Coin) | Fiat-collateralized | Circle & Coinbase | Fully backed by USD, highly regulated, and audited regularly. |
| BUSD (Binance USD) | Fiat-collateralized | Binance & Paxos | US-regulated; 1:1 USD peg; widely used on Binance exchange. |
| DAI | Crypto-collateralized | MakerDAO | Backed by crypto assets (like ETH) in smart contracts; value maintained algorithmically. |
| TUSD (TrueUSD) | Fiat-collateralized | TrustToken | Fully backed by USD, transparent, with regular audits. |
| GUSD (Gemini Dollar) | Fiat-collateralized | Gemini Exchange | US-regulated, audited, pegged 1:1 to USD. |
3. How They Maintain $1 Value
- Fiat-collateralized: Issuer holds USD or equivalent reserves; each stablecoin = 1 USD.
- Crypto-collateralized: Over-collateralized with cryptocurrencies; smart contracts automatically stabilize value.
- Algorithmic: Supply adjusts automatically based on demand to maintain $1.
4. Uses
- Quick transfers without crypto volatility.
- Trading and hedging against crypto price swings.
- DeFi applications like lending, staking, and liquidity pools.
