Bytecode verified via sibling
This contract shares identical runtime bytecode with a verified contract (0xb78b586c...) which has been verified through compiler archaeology.
Standard Truffle Migrations (unoptimized variant). Cluster of 31 identical deployments.
Key Facts
Description
One of 31 identical Truffle Migrations deployments compiled with solc 0.4.24 optimizer OFF. Public owner and last_completed_migration, restricted modifier, setCompleted(uint) and upgrade(address). Exact code match; only trailing 34-byte Swarm metadata differs.
Heuristic Analysis
The following characteristics were detected through bytecode analysis and may not be accurate.
Byzantium Era
First Metropolis hard fork. Added zk-SNARK precompiles, REVERT opcode, and staticcall.
