The Address Book app makes it easy to assign human-readable names to Ethereum addresses.
To add a new address to your Address Book, click the "New entity" button.
In the panel, input the name you want to assign to an address. You can label your new entity as either an Individual or an Organization. The Address must be a valid Ethereum address.
Once the transactions been created, navigate to the Voting app to cast your vote on adding the new entity to your Address Book.
Once the vote's been enacted, the new entity should appear on your Address Book.
To remove an existing entity, click on the menu icon associated to the entity you want to remove and click “Remove”.
If an entity is neither an individual nor an organization, you can create an entity with a “Custom type”, or in other words, a user-defined category, which can be reused across other entities.
To set up a custom type, the option can be selected from the “Type” dropdown menu. After doing so, an additional input appears right below where you can input the name. After an entity with this type gets created, the type will be reusable.
To make any modifications to an existing entity, click on the menu icon associated to the entity and choose “Update”. This will open a panel where a new "Name" or "Type" can be defined.
