# Minitel

[Minitel](http://minitel.app/) is an external transaction decoding system developed by Kiln that provides enhanced visibility before transaction approval.

{% hint style="info" %}
[minitel.app](http://minitel.app/) is the Kiln-hosted version running on Vercel. The source code is open source and can be self-hosted. Kiln is also working with partners to integrate it into their interfaces (e.g., Fireblocks). The audit report can be seen [here](https://github.com/kilnfi/minitel/blob/main/audits/Kiln%20-%20Minitel%20-%20Final%20Report.pdf) and on the Quantstamp website [here](https://certificate.quantstamp.com/full/kiln-minitel/934225af-0b19-4193-aac1-239a95d0ed17/index.html). 
{% endhint %}

The Kiln-hosted version offers dedicated Minitel instances for each blockchain ([full list](#kilns-self-hosted-minitel)) with easy navigation between these chain-specific instances.

Each chain-specific Minitel parses and decodes serialized transactions, providing **clearer visibility** by displaying transaction details in a human-readable format. The decoded data **includes warnings** for actions requiring special attention—such as modifying stake account authority.

In addition to presenting decoded transactions in JSON format, Minitel provides a **summary of the transaction's actions**. The **format varies by blockchain** to accommodate each chain's unique characteristics; for SOL, it shows an overview of each instruction.

To help users understand decoded transactions, Minitel offers an interactive **decode playbook**. The playbook's **sample mode** displays side-by-side examples of typical flows with clear, step-by-step breakdowns of each instruction—making it easier to verify transactions before signing. For each blockchain, it includes examples of supported operations (e.g., Solana: stake, deactivate, withdraw, merge, split).

# 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.kiln.fi/v1/kiln-products/more-tools/minitel.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.
