Bytecode verified via sibling
This contract shares identical runtime bytecode with MyToken (0xcae62d22...) which has been verified through compiler archaeology.
Identical token code to 0xCAe62D22E8480b230d7aD93039167a0FfA7A2B8B, deployed four minutes later with the same 200,000 supply. No transfer was ever made.
Context
Deployed 23 October 2015 at 12:34 UTC by 0xB1a2B43A7433dd150BB82227eD519Cd6b142d382, four minutes after 0xCAe62D22E8480b230d7aD93039167a0FfA7A2B8B and with the same constructor argument of 200,000. Public balanceOf mapping, a lower case balanceof function returning the same slot, transfer returning false on an insufficient balance, unindexed Transfer event, runtime 625 bytes. One call reached it after deployment and it emitted no events.
Source recovered by compiling against solc v0.1.6+commit.d41f8b7c with the optimizer off, reproducing both the deployed runtime and the creation bytecode exactly.
