# Equipping Permissions

You must grant your hero permission to  equip items. This is a single on chain action that you only need to do once for the same hero.

This is a necessary component of composable NFTs.

## How to check permissions:

You can view these permissions using the [etherscan.io](https://etherscan.io/tokenapprovalchecker) approval checker. You will need to enter your address in the search box to see its approvals.

The permission for a Pixel War Hero will be on the ERC-1155 tab and will look like this:

## Recommendations

***This is not specifically Pixel War related, but is a general recommendation.***

It is a good idea to check what permissions you have granted. You may see various permissions under the tabs: ERC-20, ERC-721, and ERC-1155.

* Check each of these tabs to see if they have open permissions.
* You may see permissions that you have granted - such as [Opensea](https://opensea.io) under the ERC-20 tab or Pixel War under the ERC-1155 tab.
* If you see permissions that you don't remember granting or no longer want, you can revoke them using the revoke button.
* There is a small gas fee associated with revoking permissions.
