Description

Deployed at block 55,365 on August 8, 2015 by 0x3D0768 - the same address that deployed the first successful HelloWorld contract on Ethereum (block 48,681). The greeting stored is 'Welcome to Walmart I love you!' - deployed using the canonical Frontier Greeter tutorial source with the greeting passed as a constructor argument. The bytecode is identical to the HelloWorld deployment; only the constructor arg differs.
