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.
