Historical Significance

One of the earliest contracts from the Oraclize team, deployed just 7 weeks after Ethereum mainnet launch. The deployer (0x0047A8033CC6d6Ca2ED5044674Fd421F44884dE8) went on to deploy the Oraclize oracle infrastructure, Ethereum's first production oracle service. This contract represents the very beginning of that development.

Context

Deployed in September 2015 during the Frontier era, compiled with Solidity v0.1.1, the earliest available compiler. At this time, smart contract development was in its infancy and developers like Thomas Bertani were experimenting with basic patterns like contract-to-contract calls that would later evolve into the Oraclize oracle architecture.

Description

A tiny proxy contract (147 bytes runtime) deployed by the Oraclize team (Thomas Bertani) on Sep 17, 2015. One of the earliest contracts from the deployer who would go on to build Oraclize, Ethereum's first oracle service.

The set(uint256) function forwards calls to a hardcoded target contract (0x9e0ae8ffd946d12d1d393c6f3bca0eecadc9428e) using early Solidity's raw string-based .call() pattern, where the function name 'set' is passed as a literal string rather than a keccak256 selector. The get() function simply returns the constant 255 (0xFF) without reading from storage.

A uint reserved variable at slot 0 suggests this was part of a larger contract hierarchy, possibly an early prototype of the Oraclize address resolver pattern. Uses inline state variable initialization for the target address rather than a constructor function.
