Identical-runtime sibling. Standard ethereum.org tutorial token (Homestead, Mar 2016): name/symbol/decimals metadata, a public balanceOf mapping and an overflow
Historical Significance
The canonical 'create your own token' contract from the ethereum.org tutorial, one of the most-copied teaching contracts of the Homestead era.
Context
Compiled with soljson-v0.2.0 (optimizer ON); exact match of the 716-byte runtime. One of 212 byte-identical deployments.
Token Information
Key Facts
Source Verified
Exact runtime bytecode match. Runtime: 716 bytes (byte-for-byte), compiled with soljson-v0.2.0+commit.4dc2445e, optimizer ON. The on-chain creation (1408 bytes) appends ABI-encoded constructor args (initialSupply, tokenName, decimalUnits, tokenSymbol) to the init code; the 716-byte runtime is the shared cluster invariant.
Heuristic Analysis
The following characteristics were detected through bytecode analysis and may not be accurate.
Frontier Era
The initial release of Ethereum. A bare-bones implementation for technical users.
