TABLE token & identification

Tables are guaranteed unique across all chains based on a combination of developer and environment defined information.

Uniqueness & convention​

A table’s full "name" is in the format: {prefix}_{chainId}_{tableId}.

Tables are ERC721 TABLE tokens minted at a Tableland registry contract deployed on each respective chain. Every table has a unique name on both the chain it was minted on and across any chain that Tableland supports. The name is comprised of three parts:

  • prefix ⇒ Optionally defined by the table creator at the time of table creation (maximum 32 bytes in length).
  • chainId ⇒ Identifier assigned to the table under the hood, based on the chain the table was created on.
  • tableId ⇒ Unique identifier for a table, assigned by the Tableland "registry" contract upon table creation (a table is minted as an ERC721 token).

For example, a table name might look like healthbot_11155111_1—this means the table has a prefix "healthbot" and was minted on Ethereum Sepolia (chain ID of 11155111) as the first table on that chain (token ID of 1).

The TABLE Token​

For each of the contracts deployed above, a globally unique TABLE ERC721 token will be minted. Anyone can create and own a table. On-chain access controls can be established to make the table itself collaborative in nature, such as a shared ownership model where certain permissioned users can insert or update rows in the table itself.

At a minimum, a TABLE owner has permissions to do whatever they want with the table, such as inserting new rows, updating / deleting existing ones, or setting a table controller that manages table the access controls. For example, take a table minted on Ethereum that tracks user session data. The table metadata has a number of characteristics, including the table's name, description, schema, image, animation URL, and created time.

    ]
  }
}

All of this information is also rendered in an SVG representation as well as a Tableland Console panel that allows you to query the data at the animation URL.
