# Detokenization

How to detokenize TCO2s into CORCs in the Puro Registry.

Similar to tokenization, the process of detokenizing requires that you hold a Puro.earth account and be onboarded as a "Trader" into the Toucan Sales Channel.

### Step 1: Onboard to Toucan's bridge

{% hint style="info" %}
If you've already done this, skip to step 2 below.
{% endhint %}

1. Go to the [Puro bridge onboarding and tokenization form](https://form.typeform.com/to/uwLStfFZ) and select the onboarding option.
2. Fill in the necessary details, which will include information about your organization and a prompt to accept the bridge’s Terms and Conditions.

### Step 2: Request that Puro Sets up Your Trader Account

{% hint style="info" %}
If you've already done this, skip to step 3 below.
{% endhint %}

This step requires that you send an email to Puro. They will submit a Trader Onboarding Proposal, which Toucan will then accept via Puro's API. Please use the format in the toggle below. If you have any questions about this email, contact us at <support@toucan.earth>

### Step 3: Submit Detokenization Request

# 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.toucan.earth/toucan/carbon-bridge/puro-carbon-bridge/detokenization.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.
