Owner-controlled deposit wallet. Sweeps ETH via collect() and ERC20 tokens via collectToken(address). Includes destroy() for deposit address cleanup.
Key Facts
Description
A simple forwarding wallet contract deployed en masse (13,600+ identical siblings) starting September 2017. The contract stores an owner address and provides functions to collect ETH, sweep ERC20 token balances to the owner, and selfdestruct. All mutating functions are owner-only via a modifier pattern. The contract accepts ETH via a payable fallback function.
Functions: collectToken(address) sweeps a token's full balance to owner, collect() sends all ETH to owner, destroy() selfdestructs to owner, owner() returns the owner address.
Near-exact source reconstruction: the compiled bytecode from soljson v0.4.12 with optimizer ON matches 669 of 670 runtime bytes. The 1-byte difference is in the code section, likely from a minor source detail (variable naming or whitespace) that affects the Solidity metadata hash.
Source Verified
Near-exact match: 669/670 runtime bytes identical. Compiler: soljson v0.4.12+commit.194ff033 optimizer ON. Source reconstructed from bytecode: 4 functions (collectToken, destroy, owner, collect) + payable fallback. All 61 v0.4.11-v0.4.12 nightlies tested. 1-byte gap from unknown source detail.
