Payable constructor that splits incoming ETH between Vitalik's two addresses; the 51-byte runtime stub embeds solc's swarm hash metadata.
Historical Significance
Third SplitOnDeploy deployed by Vitalik Buterin's personal deployer (0x1db3439a) on March 31, 2017. Uses a payable constructor (unlike the earlier 0.4.4 instances) and was compiled with solc 0.4.9–0.4.11, which introduced the swarm hash CBOR metadata suffix — making the deployed runtime 51 bytes instead of 12. The constructor and runtime logic match exactly; only the swarm metadata hash differs from the reconstructed source.
Key Facts
Source Verified
Compiled with solc 0.4.9-0.4.11, no optimizer. Constructor bytes + runtime logic are exact; trailing 32-byte swarm hash encodes original source file content.
