# 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).
