What is a stablecoin, and why does a dollar target not guarantee its value?

A stablecoin is a digital asset designed to track a reference value, sometimes the dollar. The word stable describes the mechanism's target, not a promise that losses cannot occur. Before relying on the name, understand how the peg is intended to work and who is responsible for it.

The same target, different mechanisms

Ethereum.org's explanation presents different stablecoin models, including mechanisms backed by assets or digital collateral. A similar target price therefore does not mean that every coin relies on the same arrangement.

Record the intended reference asset, the collateral described and who publishes information about the mechanism. Distinguish a general document from data relating to a particular date. A headline on an issuer's website is no substitute for reading the terms.

Ask about redemption, not just price

Who is entitled to redeem the token with the issuer, if anyone? Under what conditions, amounts and fees? Is what you see on a trading platform an opportunity to sell on the market or a direct redemption right? These are not necessarily the same action.

This is not a list of recommended issuers. A useful comparison asks each service the same questions and marks what remains unclear. Do not assume that one coin's terms apply to another.

The network and the risk do not disappear

When transferring, you also need to check which network the sender and recipient support. A coin's name alone does not specify the transfer method. Read the current instructions from the services involved before sending.

A peg target does not turn the product into a bank deposit or guarantee a particular price at every moment. When reading about a stablecoin, the central questions are who stands behind it, what the mechanism actually promises and what it does not.
