Description

One of 143 identical minimal ETH forwarders. The payable fallback loads the destination address from state slot 0 (set at construction) and forwards msg.value via .send(), wrapped in require() to revert if the send fails. No other functions, no configurable state beyond the single destination slot. Compiled with solc 0.4.17+commit.bdeb9e52 optimizer ON runs=200. Exact code match; only trailing 34-byte Swarm metadata differs.
