+### Token Standard
+
+Tag\_type 'token standard' is a set of tags that define the token standard of an address!
+
+| tag\_name      | description                           | blockchains |
+| -------------- | ------------------------------------- | ----------- |
+| erc-20         | An erc-20 address                     | ethereum    |
+| erc-721        | An erc-721 address                    | ethereum    |
+| erc-1155       | An erc-1151 address                   | ethereum    |
+| erc-4626       | An erc-4626 address                   | ethereum    |
+| erc-6551       | An erc-6551 address                   | ethereum    |
+| erc-6551 owner | A token address that owns an erc-6551 | ethereum    |
+
+Want to know the difference in behaviors of erc-721's vs. erc-1155's? Leveraging the 'token standard' tag\_name will make this segmentation and subsequent analysis trivial!
+
+The code below will find all erc-721s that are on Ethereum! 
+
+```sql
+select 
+  distinct address
+from crosschain.core.address_tags 
+where 
+    tag_type = 'token standard' 
+    and tag_name = 'erc-721'
+    and creator = 'flipside'
+```
+
 ### Contract
 
 Tag\_type 'contract' is a group of tags that call out contract addresses! \
