Fixed supply of 21 million units at eight decimals, all held by the deployer.
Context
Deployed in October 2016 during the Homestead era.
Token Information
Key Facts
Description
The whole supply is credited to the deploying account at creation and can only move through a single transfer call. There is no approval or allowance system, no minting and no owner. The constructor rejects any ether sent with the deployment and the fallback function throws, so the contract can never take custody of ether.
