Historical Significance

DoucheCoin is a joke ticker on an otherwise unmodified tutorial token: transfers, third-party allowances and an approveAndCall hook for contracts that want to be notified when they are approved. The deployer minted 1,000,000 base units against 8 decimals into their own account and left no way to make more and no way to freeze anyone out. Its runtime sits 26 bytes away from the token at 0xfcaf204852781b57c23023aa28f21437f7303505, and every one of those bytes is a jump target or a reordered stack shuffle, which is the signature of one source compiled by two different builds.

Context

Deployed a month before the DAO exploit, at the peak of the 2016 token launch wave.
