Deployed March 24, 2016 (10 years ago)Block 1,209,730

The canonical SimpleStorage (Homestead, Mar 2016): a single uint with set(x) and a constant get() getter, the opening example of the Solidity documentation.

Homestead EraVerified Source

Historical Significance

The 'hello world' of Solidity: the first example from the official documentation, storing and returning a single integer.

Context

Compiled with soljson-v0.1.5 (optimizer OFF); exact match of both the 151-byte runtime and 167-byte creation bytecode. One of 18 byte-identical deployments.
