Ten thousand units at two decimals, with allowances that are set but never granted.
Context
Deployed in June 2016 during the Homestead era.
Token Information
Key Facts
Description
It keeps an allowance mapping and honours it in transferFrom, but exposes no function that writes to it, so no holder can ever authorise a spender and transferFrom can never succeed. The whole supply is credited to the deploying account at creation and nothing can mint more. Sending ether to it throws.
