# Tokenization
At a high level, the tokenization of carbon removal credits, or CORCs, via our Puro carbon bridge involves a few steps:
1. **Request Tokenization**: Provide details such as the serial numbers of the credits you want to bridge, the project name, and the destination address to Toucan. Further instructions on this are below.
2. **CORCs are Locked**: Upon tokenization, credits will be immobilized in an omnibus account within the Puro Registry for as long as the tokenized version exists.
3. **Toucan Mints a Batch NFT**: Toucan mints an NFT onchain that contains details about the tokenization event.
4. **Deliver TCO2 Tokens**: Toucan will fractionalize the Batch NFT into TCO2 tokens, each representing one CORC that has been tokenized. The TCO2 tokens will be delivered to the wallet address provided.
## Instructions to Tokenize
### 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: On-Ramp Assets to Toucan's Sales Channel in Puro Registry
The process of on-ramping transfers your Puro CORCs into Toucan's Sales Channel within the Puro Registry. Your assets must be in our Sales Channel to proceed with tokenization.
Also, each bridge user must be onboarded as a recognized “Trader” within the Sales Channel. The first time you use our bridge, follow step 2a so that Puro sets this up for you.
2a. For first time users (Puro account holders who have not yet on-ramped any assets to Toucan’s Sales Channel)
Send the following email to Puro. If you have any questions preparing this email, contact .

### Step 3: Submit Tokenization Request

Once your request is processed, the offchain CORCs will be batch-minted as an ERC-721 NFT. This NFT will then be fractionalized into ERC-20 TCO2 tokens and deposited into the onchain wallet you specified in the request form.
