ENTITY

# asset

An asset represents anything that is fungible. It can be more than money,
like resources in a game.

```signature
entity asset {
 key id: byte_array;
 key name: text;
 key symbol: text;
 decimals: integer;
 key issuing_blockchain_rid: byte_array;
 mutable icon_url: text;
 index type: text;
 mutable total_supply: big_integer;
 key uniqueness_resolver: byte_array = x"";
}
```

`key id: byte_array;`
:   Unique identifier for an instance of this entity

`key name: text;`
:   Display name of the asset. Need not be unique.

`key symbol: text;`
:   Symbol of this asset, typically an all caps string of
    three or four letters. Used for display purposes and
    need not be unique.

`decimals: integer;`
:   Number of decimals used by this asset, which will affect
    how to interpret a balance of this decimal. E.g.,
    10000 with decimals 1 would be interpreted as 1000,0 while
    10000 with decimals 2 would be interpreted as 100,00

`key issuing_blockchain_rid: byte_array;`
:   The rid of the blockchain that is issuing this asset if this
    is a cross chain asset. For non-cross chain assets, this field
    will be the same as this blockchain's RID.

`mutable icon_url: text;`
:   A URL to an icon for this asset. Used only for display
    purposes in UI applications.

`index type: text;`
:   The type of asset. Defaults to ASSET\_TYPE\_FT4

`mutable total_supply: big_integer;`
:   Integer representing the total supply of this asset.
    Can change as assets is minted/burnt.

`key uniqueness_resolver: byte_array = x"";`
:   Attribute that contains additional data to discern assets that are
    registered with the same name and symbol.
