### Question

Where should a CASP exchanging crypto-assets for funds or other crypto-assets publish the “firm price or method of determining the price of the crypto-assets" as required by [Article 77(2)](/mica/title-v-authorisation-and-operating-conditions-for-crypto-asset-service-providers-art.-59-85/chapter-3/article-77.md) of MiCA? Where should they publish the “information about the transactions concluded by them, such as transaction volumes and prices”, as required by [Article 77(4)](/mica/title-v-authorisation-and-operating-conditions-for-crypto-asset-service-providers-art.-59-85/chapter-3/article-77.md) of MiCA?

***

### Answer

CASPs providing the service of exchange of crypto-assets for funds or other crypto-assets should publish the information required under paragraphs 2 and 4 of Article 77 in a publicly available location (e.g. on their website) that is accessible to all without registration.

The quotations published under [Article 77(2)](/mica/title-v-authorisation-and-operating-conditions-for-crypto-asset-service-providers-art.-59-85/chapter-3/article-77.md) of MiCA should include all elements allowing a party to anticipate with certainty the price at which an exchange would be made.

The information published under Article 77(4) on executed transactions should remain available for a sufficient period of time. The information would typically be expected to be available until midnight of the following business day.

CASPs are strongly encouraged to align as much as possible with the format prescribed in the Commission Delegated Regulations on pre-trade and post-trade transparency and record keeping once these Regulations are finalised and made available.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.mica.wtf/eu-level/q-and-a/esma-qa-2181-publication-information-casps-providing-service-exchange.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
