What Is a Stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value, typically by being pegged to a reserve asset such as the US dollar. While coins like Bitcoin and Ethereum can swing sharply in price, a stablecoin aims to stay at or near a fixed value (for example, 1 USDT ≈ $1).
Stablecoins bridge traditional finance and crypto: they offer the price stability of fiat money with the speed, global reach, and programmability of blockchain. They're widely used for trading, payments, savings, and as a safe harbor during volatility.
How Do Stablecoins Stay Stable?
| Type | How the Peg Is Maintained | Example |
|---|---|---|
| Fiat-backed | Reserves of cash/equivalents held 1:1 | USDT, USDC |
| Crypto-backed | Over-collateralized with crypto | DAI |
| Algorithmic | Algorithms adjust supply to hold the peg | (higher risk) |
| Commodity-backed | Backed by gold or other assets | PAXG |
How Are Stablecoins Used?
Trading — a stable base pair to move in and out of volatile assets.
Payments and remittances — fast, low-cost global transfers.
Savings — holding value without exposure to crypto volatility.
DeFi — lending, borrowing, and yield without price swings.
Why Do Stablecoins Matter?
Stability — avoid crypto volatility while staying on-chain.
Speed and cost — settle globally in minutes, often cheaply.
Accessibility — dollar-like access for people without bank accounts.
DeFi backbone — core liquidity across decentralized finance.
Risks to Understand
Stablecoins are only as reliable as their backing and design. Fiat-backed coins depend on the issuer actually holding sufficient reserves; algorithmic models have failed dramatically in the past. Regulatory scrutiny is also increasing. "Stable" is a goal, not a guarantee — a peg can break.
Stablecoins and Trust Wallet
Trust Wallet supports major stablecoins like USDT and USDC across multiple networks (such as ERC-20, BEP-20, and TRC-20), so you can store, send, receive, and swap them with ease. As a non-custodial wallet spanning 100+ blockchains, you keep full control of your keys — just always confirm you're using the correct network when sending stablecoins, since the same coin can exist on several chains.
