Description

Deployed June 23, 2016 by Vitalik Buterin (0x1db3439a22ee7c4d034e9b26437d3960b5af0517). This is an empty Solidity contract: contract Empty {} with no storage, no constructor body, and no functions. The 10-byte runtime (60606040526008565b00) is the canonical empty-contract stub emitted by the solc 0.3.x series: the free-memory-pointer prologue followed by an empty dispatcher trampoline that halts.

Runtime bytecode reproduces byte-for-byte from the reconstructed source using solc 0.3.6 with the optimizer off. solc 0.4.0 emits a different tail, pinning this to the 0.3.x line. The contract name is not recoverable from an empty contract's bytecode, so a neutral placeholder name is used.
