Sumokoin (SUMO)

Sumokoin (SUMO) is a privacy-focused cryptocurrency that forked from Monero, created to offer highly confidential transactions with enhanced default anonymity settings. The project’s name references sumo wrestling, and its visual identity uses a circular emblem format that has been distributed across cryptocurrency logo directories and the project’s official channels.

Design and History

Sumokoin was introduced as a fork of Monero, with the project describing itself as “Digital Cash For Highly-Confidential Transactions.” The GitHub repository for the project, maintained by Sumokoin Projects, documents the coin’s development from 2017 onward and identifies the coin symbol as SUMO. The project’s official website is sumokoin.org, which serves as the primary distribution point for the brand’s assets. [1]

The Sumokoin logo is available in PNG and SVG formats through multiple cryptocurrency logo directories, which host the mark for use across exchanges, wallets, and informational sites. These directories consistently present the logo as a square or circular icon, reflecting the standard format used across the cryptocurrency industry for token identification. [2] [3]

The mark has remained consistent across the directories that host it, with no evidence of a major visual overhaul since the project’s launch.

Meaning and Symbolism

The Sumokoin name and branding draw from sumo wrestling, a connection reinforced by the project’s Japanese-language name, スモコイン, which appears in the official GitHub repository. The project’s unit denominations also follow this theme, with the smallest unit called a “Sumoshi” and larger units named “Sumokun” and “Sumosan.” [1]

The logo’s appearance as a circular emblem is consistent with the icon format used broadly across cryptocurrency branding, but the project has not published an official brand guideline explaining the design intent.

Typography and Design

The Sumokoin logo is distributed as a vector SVG file, allowing for scalable reproduction across digital and print applications. The mark is also offered in PNG format at multiple sizes, including large (250×250), standard (64×64), small (50×50), and thumbnail (25×25) variants, which are commonly used for exchange listings and wallet interfaces. [3]

The project has not published a formal brand style guide, and the available evidence does not support claims about specific font choices or exact color specifications beyond what is visible in the distributed logo files.
