A stablecoin is a token that promises to be worth one unit of something else, usually a dollar. The promise is only as good as whatever is held to honour it.

## The cloakroom analogy

Think of a cloakroom ticket. The ticket is worth a coat because there is a coat on a hook with your number on it. If the cloakroom has sold more tickets than it has coats, the tickets are still printed and still look the same.

A stablecoin is the ticket. The reserve is the coat. Everything that matters is in the second half of that sentence.

## What is usually held

For the large dollar stablecoins, mostly short-dated government debt and cash at banks. Treasury bills maturing within three months make up the bulk, because they are the closest thing to cash that still pays something.

That is the conservative version. Other designs hold corporate debt, other crypto assets, or nothing at all beyond an algorithm, and those have failed more often.

## How to check

Issuers of the main dollar stablecoins publish attestations, usually monthly. An attestation is not a full audit. It is an accountant confirming that on a given date the reported holdings existed.

Read three things: the date, who signed it, and whether the total exceeds the tokens in circulation. If any of those is missing or vague, that is the finding.

## What an attestation does not tell you

Whether the reserve was adequate yesterday or will be tomorrow. Whether the bank holding the cash is sound. Whether the issuer can sell the assets quickly in a bad week.

Those are judgements the document cannot make for you.

## Why it matters even if you hold for an hour

Payment users often argue that short holding periods make reserves irrelevant. They do not. A peg breaks in minutes, and the hour you hold may be that hour.

If you are moving value regularly, use [an exchange that treats stablecoins as a settlement asset](https://collectnexchange.cy/services/stablecoin) rather than a venue that treats them as one more trading pair.

## The practical position

Hold the one with the clearest reserve reporting, not the one with the best yield. Yield on a stablecoin comes from somewhere, and that somewhere is usually risk that has been moved rather than removed.

Where you hold it matters as much as which one. [Collect & Exchange](https://collectnexchange.cy/) publishes what it holds and under which licence, and [somewhere the redemption path is written down](https://collectnexchange.cy/services/crypto-offramp) is worth more than a slightly better rate.
