The classic Ethereum Hello World contract. mortal base with kill(), greeter with greet(). One of 111 identical deployments.
Historical Significance
The canonical first contract for Ethereum developers. The mortal + greeter pattern taught inheritance, constructors, and selfdestruct.
Key Facts
Description
The Greeter is Ethereum's Hello World - the first contract most developers deployed from the official tutorials. It inherits from mortal (which provides kill/selfdestruct) and stores a greeting string set at construction.
111 identical deployments of this bytecode exist, representing the wave of developers who followed the tutorial and deployed their own Greeter.
