# Blockchain pairing

### Purpose

Pairing a blockchain account to your Spacehall account enables communities to give you specific permissions related to your on-chain activity.

For example:

* A layer one blockchain community could only allow user interactions from users with a paired account on their blockchain.
* A  validator community could only allow user interactions from users who delegate to them on given chains.
* A DAO community could only allow user interactions with users who are part of their DAO.

### Pair a blockchain account.

1. Go to your account settings by clicking on your avatar in the top right corner and then "settings."

4. You're now presented with the details of the unique pairing transaction you need to execute to confirm the ownership of your account.

5. Using your favorite wallet, send a transaction from the blockchain account you're trying to pair using the information you got from point 4.

{% hint style="danger" %}
The transaction recipient should be the address of the account you are trying to pair. Do not copy the one in the screenshot.
{% endhint %}

{% hint style="warning" %}
Do not forget to set the memo. Verification will fail if absent.
{% endhint %}

5. Then click "Verify transaction." Once your transaction is found, your blockchain account will be automatically paired with your Spacehall account.
6. You can wait until the verification is done or close the modal, as it will continue in the background.
