Description
Identical bytecode to 0xFF2947b1851bB16a7C8E71C6a8458D29600F9D6a, deployed one day later. Both share the same 1648-byte runtime bytecode — differing only in constructor arguments (the name field set at deployment).
This is a dual-send subcurrency with exchange-authorized transfers, compiled with soljson v0.1.1 (emscripten, no optimizer). Deployed 44 days after Ethereum mainnet launch.
