Byte-identical deployment of: The classic Frontier 'greeter' (Jan 2016): a mortal-derived contract storing a constructor-set greeting returned by greet(), with

Frontier EraVerified Source

Historical Significance

The greeter from the original Frontier release walkthrough, the first contract many early developers ever deployed.

Context

Compiled with soljson-v0.2.0 (optimizer OFF); exact match of the 542-byte runtime. One of 67 byte-identical deployments.

View verification proof

Exact runtime bytecode match. Runtime: 542 bytes (byte-for-byte), compiled with soljson-v0.2.0+commit.4dc2445e, optimizer OFF. The on-chain creation (908 bytes) appends the ABI-encoded greeting constructor string; the 542-byte runtime is the shared cluster invariant.
