### 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! \
