Description

This contract is the first of 144 identical ETH forwarders. A single payable fallback reads the destination address from state slot 0 (set at construction) and immediately forwards the received msg.value via .transfer(). No other functions. Compiled with solc 0.4.17+commit.bdeb9e52 optimizer ON runs=200. Exact code match; only the trailing 34-byte Swarm/CBOR metadata hash differs from source-formatting delta.
