Description

One of 177 identical owner-only ERC-20 sweep contracts. Two internal state slots: address owner at slot 0 and ERC20 token at slot 1. A single mutation SendTokens(uint256 amount) first checks msg.sender == owner (silently returns on mismatch — no revert) and then invokes token.transfer(owner, amount). Compiled with solc 0.4.15+commit.bbb8e64f optimizer ON runs=200. Exact code match; only trailing 34-byte Swarm metadata differs.
