Deployed September 1, 2015 (11 years ago)Block 174,032

A third deployment of the msgExaminer that records its own creation message

Frontier EraVerified Source

Historical Significance

What msg and tx actually contain, written down by measurement rather than from the documentation. Recording the same globals at construction and again during a later call is the only way to see which of them change and which are fixed, and in 2015 the documentation for several of these was thin enough that measuring was the reliable route.

Context

Frontier era deployment by Cyrus Adkisson, from his Solidity teaching repository.

Description

Byte for byte identical to 0x46dce1955e40d23a6ed0b745b517ae08aa3086aa and 0xba575c0c66ec866a308dcd4cb3dbd3a83d78733f. It saves msg.data, msg.gas, msg.value, tx.gasprice and tx.origin at construction time and again around a send, so the two sets can be compared. Deployed 24 August 2015 and later destroyed.
