A Frontier-era Greeter contract with the message: 'Hello World!'
Historical Significance
One of many early Greeter deployments showing real developers learning Solidity on the live Ethereum network in 2015.
Key Facts
Description
Deployed during Ethereum's Frontier era using the canonical mortal+greeter tutorial source from the Solidity documentation. The greeting stored is 'Hello World!'. Verified as an exact bytecode match against the greeter-verification repo.
Source Verified
Creation TX matches: compiled Greeter base (692 bytes) + ABI-encoded greeting. soljson v0.1.1+commit.6ff4cd6a, optimizer OFF.
Heuristic Analysis
The following characteristics were detected through bytecode analysis and may not be accurate.
Frontier Era
The initial release of Ethereum. A bare-bones implementation for technical users.
