Getting Started

The best way to get started is to run through the tutorial.

Implicit Attributes

There are a few implicit attributes available:

  • name
  • symbol
  • contractAddress
  • ownerAddress
  • tokenId

tokenId is especially useful for defining attributes with a function origin like this:

<ts:attribute-type id="locality" syntax="1.3.6.1.4.1.1466.115.121.1.15">
  <ts:origins>
    <ts:ethereum function="getLocality" contract="EntryToken" as="utf8">
        <ts:data>
          <ts:uint256 ref="tokenId"/>
        </ts:data>
    </ts:ethereum>
  </ts:origins>
</ts:attribute-type>

This is written with the assumption that the getLocality() smart contract function expects a single uint256 argument representing the tokenId.

Here's another example with ERC721's ownerOf(uint256):

<ts:attribute-type id="owner" syntax="1.3.6.1.4.1.1466.115.121.1.15">
  <ts:origins>
    <ts:ethereum function="ownerOf" contract="MyToken" as="address">
        <ts:data>
          <ts:uint256 ref="tokenId"/>
        </ts:data>
    </ts:ethereum>
  </ts:origins>
</ts:attribute-type>
