FrontierContract #3,202Exact Bytecode MatchEdit this contract

Deployed November 2, 2015 (10 years ago)Block 477,409

The classic Frontier 'greeter' (Nov 2015): a mortal-derived contract storing a constructor-set greeting returned by greet(), with an owner-only kill().

Frontier EraVerified Source

Historical Significance

An early-Frontier deployment (block 477,409, Nov 2015) of the canonical greeter walkthrough, built with the v0.1.5 compiler.

Context

Compiled with soljson-v0.1.5 (optimizer OFF); exact match of the 542-byte runtime. One of 18 byte-identical deployments; a distinct compiler build from the v0.2.0 greeter cluster.

View verification proof

Exact runtime bytecode match. Runtime: 542 bytes (byte-for-byte), compiled with soljson-v0.1.5+commit.23865e39, optimizer OFF. The on-chain creation (908 bytes) appends the ABI-encoded greeting constructor string; the 542-byte runtime is the shared cluster invariant.
