Stablecoins Explained

Stablecoins are cryptocurrencies designed to hold a steady value, usually pegged to a national currency such as the US dollar. They act as the cash layer of crypto: a place to sit between trades, a medium for payments, and the base currency of much of DeFi. This page explains the different types, how a peg is meant to hold, and what can make one fail.

Why stablecoins exist

The prices of Bitcoin, Ethereum and most altcoins move constantly. Stablecoins give traders and users a way to hold value on-chain without that volatility — settling trades, moving money between platforms, or earning yield, all while staying close to a fixed value. That makes them central to crypto market plumbing.

The three main types

How a peg holds — and breaks

A peg is only as strong as the mechanism behind it. Fiat-backed coins rely on the issuer holding enough high-quality, redeemable reserves. Crypto-backed coins rely on holding more collateral than the value issued. Algorithmic designs rely on market incentives alone, which is why several have failed dramatically. When confidence drops, a stablecoin can “depeg” — trade below its target — and may or may not recover.

What stablecoins are used for

• Trading: a neutral base pair to move in and out of positions.
• Payments & transfers: fast settlement without bank hours.
• DeFi: lending, borrowing and providing liquidity, covered under DeFi.

Reserves, attestations and transparency

A fiat-backed stablecoin is only as trustworthy as the assets behind it. Reputable issuers publish regular attestations or reports describing what backs the coin — typically cash and short-term government securities — and some are independently examined. As a holder, the questions worth asking are simple: what exactly are the reserves, who verifies them, and how quickly can the issuer honour redemptions? Opaque or unaudited backing is a meaningful risk, because the entire value proposition rests on the promise that each token can be redeemed for the asset it represents.

Regulation and oversight

Stablecoins sit at the boundary between crypto and the traditional financial system, so they attract particular regulatory attention. Frameworks emerging in several jurisdictions focus on reserve quality, redemption rights and issuer disclosure. The practical takeaway for users is that the rules around stablecoins are still developing and vary by region — the landscape we describe on our regulation page applies here in full.

Risks to keep in mind

“Stable” describes the design goal, not a guarantee. History includes stablecoins that lost their peg, most notably the 2022 collapse of an algorithmic stablecoin that was not backed by reserves and unravelled rapidly. Even asset-backed coins can wobble during stress if redemptions are doubted. Treat a stablecoin as a tool with its own counterparty and smart-contract risks rather than as a risk-free cash equivalent.

How people use stablecoins in practice

For many users, stablecoins are the connective tissue of the crypto market. Traders park funds in them to step out of a volatile position without converting all the way back to a bank account, then redeploy quickly when they see an opportunity. They are widely used as the unit of account on exchanges, where countless pairs are quoted against a stablecoin rather than a national currency. In DeFi, stablecoins are a core building block for lending, borrowing and providing liquidity. And because they move on public networks, they can settle cross-border transfers quickly, which is part of their appeal in regions with limited banking access.

Choosing and handling a stablecoin

If you decide to hold one, a few practical checks help. Prefer issuers that are transparent about reserves and redemption, understand which network a given token lives on so you do not send it incorrectly, and remember that holding a stablecoin still exposes you to the issuer and to the smart contracts you interact with. A stablecoin reduces price volatility; it does not remove the other risks that come with holding any crypto asset. Treat it as a useful tool with clearly defined limits rather than a perfect substitute for cash in a bank.

Key questions before holding one

If you are weighing whether to use a stablecoin, a short checklist cuts through the marketing. What backs it — cash and government securities, other crypto, or an algorithm with no reserves at all? Who verifies those reserves, and how often? How quickly and reliably can the token be redeemed for the asset it represents? Which network does it run on, so you transfer it correctly? And what would happen to your funds if the issuer or the underlying smart contract ran into trouble? Honest answers to these reveal how much trust a given stablecoin actually deserves. The strongest options are transparent on every count; the riskiest tend to be vague about exactly these questions.
