Basic ethereum.org token template with name, symbol, decimals, balanceOf, and transfer. One of 200 identical deployments.
Historical Significance
The entry-level token template that taught thousands of developers to create tokens on Ethereum.
Token Information
Key Facts
Description
The simplest token contract from the official ethereum.org tutorials. Implements basic token functionality: name, symbol, decimals, balanceOf mapping, and transfer with overflow checking. No approve/transferFrom (pre-ERC-20 standardization).
200 identical deployments make this one of the most widely used token templates from early 2016.
Source Verified
Exact runtime bytecode match. Native C++ solc v0.2.1 (webthree-umbrella v1.1.2), optimizer ON. 200 identical siblings.

Frontier Era
The initial release of Ethereum. A bare-bones implementation for technical users.
