# Claim Issuer

These guides cover what a Claim Issuer does: attesting a fact about an identity by adding a signed claim to it, and withdrawing that attestation when it no longer holds. The claims a Claim Issuer adds are what makes an investor eligible for the assets that trust that issuer.

| Order | ID | Guide                                                                                                        | What it does                                                                        |

| 3     | 29 | [Bring an EAS attestation in as a claim](/guides/claim-issuer/29.-bring-an-eas-attestation-in-as-a-claim.md) | Makes an attestation that exists on EAS count as a claim, through the adapter.      |

The "Order" column is the order in which these operations are usually performed. The "ID" column is the permanent reference number of each guide. See [How guides are numbered](/guides/about-the-guides.md).

A Claim Issuer's own identity is created with [02 Deploy an ONCHAINID](/guides/identity/02.-deploy-an-onchainid.md), and its signing keys are managed with [22 Add and remove keys on an ONCHAINID](/guides/identity/22.-add-and-remove-keys-on-an-onchainid.md). An Issuer starts counting its claims with [04 Add a trusted Claim Issuer](/guides/issuer/04.-add-a-trusted-claim-issuer.md).

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.t-rex.network/guides/claim-issuer.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
