Stablecoins Explained: USDT, USDC, DAI and What's Next
Stablecoins are the backbone of crypto. Here's how they actually work.
What Makes a Stablecoin Stable
- Fiat-backed (USDT, USDC): 1:1 reserves in dollars. The company holds the cash
- Crypto-backed (DAI): Overcollateralized by crypto assets in smart contracts
- Algorithmic (UST, R.I.P.): No reserves, algorithm tries to keep peg. This failed spectacularly
The Big Three
| Coin | Backing | Risk |
|---|---|---|
| USDT | Fiat (claims 100%) | Transparency questions |
| USDC | Fiat (audited) | Very low |
| DAI | Crypto (overcollateralized) | Smart contract risk |
Why They Matter
- On/off ramps for trading
- Yield farming base asset
- Remittances and payments
- Store of value during volatility
What's Next in 2026
- RWA-backed stables (treasuries)
- Regional stables (EURC, etc.)
- Yield-bearing stablecoins
The stablecoin market is growing faster than almost anything in finance. Understanding the differences keeps you safe.
