Glossary: Stablecoins
Stablecoins are tokens designed to track a reference asset, often the U.S. dollar. Their reserves and redemption rules vary, and a stablecoin can lose its peg.
What is a Stablecoin?
Stablecoins are tokens designed to maintain a value relative to a reference asset, commonly a fiat currency. Fiat-backed, crypto-collateralized, commodity-backed, and algorithmic designs carry different risks; a peg is not guaranteed.
Stablecoins Explained
Regular crypto is volatile. The price of Bitcoin or Ethereum can swing 20% in a single day, which makes it difficult to use for everyday transactions or as a reliable store of value.
A stablecoin solves that problem. It is designed to track a reference value, but stability is not guaranteed. Fiat-backed, crypto-collateralized, commodity-backed, and algorithmic designs have different risks, and a stablecoin can depeg.
Think of it as the calm, predictable version of crypto. You get the benefits of blockchain, fast transfers, no banks, global access, without the price rollercoaster.
What a Stablecoin Means For
Audience | Use Case |
|---|---|
Crypto traders and investors | Park value in a stable asset during market volatility without converting back to fiat and leaving the crypto ecosystem |
DeFi users and protocols | Use stablecoins as the base currency for lending, borrowing, and liquidity provision without exposure to price volatility |
Businesses and individuals in emerging markets | Access a stable dollar-denominated asset without needing a US bank account or exposure to local currency inflation |
Examples
A trader moves funds into USDC during a market downturn to preserve value while staying on-chain and ready to redeploy when conditions improve.
A DeFi protocol uses stablecoins as the primary collateral and borrowing asset in its lending markets, reducing liquidation risk for users compared to volatile collateral.
A freelancer in a high-inflation economy receives payment in USDT instead of local currency, protecting their earnings from devaluation while keeping funds accessible.
A protocol uses a stablecoin as the unit of account for its treasury, ensuring that operational expenses can be planned and met without exposure to token price swings.

FAQs
What are the main types of stablecoins?
There are three main types: fiat-backed stablecoins held in reserve, crypto-backed stablecoins overcollateralized with on-chain assets, and algorithmic stablecoins that use code-based mechanisms to maintain their peg.
Are stablecoins truly stable?
Most maintain their peg under normal conditions. But stablecoins can depeg during extreme market stress, liquidity crises, or if the underlying backing mechanism fails, as seen with algorithmic stablecoin collapses.
How should USDC and USDT be compared?
Both are widely used dollar-referenced stablecoins, but their issuers, reserve disclosures, redemption terms, chain deployments, liquidity, and regulatory treatment differ. Check current issuer reports and the specific chain and venue; these details can change.
Are stablecoins regulated?
Regulation is evolving rapidly. Several jurisdictions including the US and EU are actively developing stablecoin-specific frameworks that would require issuers to meet reserve and disclosure standards.
Can you earn yield on stablecoins?
Some lending and liquidity protocols pay returns on stablecoin deposits, but returns are not guaranteed. Risks can include depegging, smart-contract failure, liquidation, liquidity constraints, and counterparty or bridge exposure.
