Ethereum Symbol (Ξ)
The Ethereum symbol is commonly represented by the uppercase Greek letter Xi (Ξ, U+039E) or by the stylized diamond octahedron logo. Ethereum's native cryptocurrency is Ether (market ticker: ETH), which powers smart contracts on the Ethereum blockchain.
Cryptocurrency Standards & Typography Notice
ETH is an open-market digital asset ticker, not an official ISO 4217 fiat currency code. The glyph Ξ (GREEK CAPITAL LETTER XI) is an ordinary letter borrowed from standard historical alphabets, not an official standalone currency sign.

Typography & International Usage Guidelines
Ethereum is a decentralized software network, not a sovereign national currency, and has no official ISO 4217 standard currency code. The market ticker is ETH. Ether can be divided into 18 decimal places; the smallest unit is 1 Wei (10^-18 ETH), with gas fees priced in Gwei (10^-9 ETH).
Common Mistakes to Avoid
- Claiming ETH is an ISO 4217 currency code (ETH is a digital asset market ticker).
- Believing Ξ was designed as a currency symbol (it is the standard Greek letter Xi, U+039E).
- Confusing the platform name (Ethereum) with the currency name (Ether).
Historical Background & Monetary Evolution
Ethereum was proposed in late 2013 by programmer Vitalik Buterin and officially launched on July 30, 2015. While the Ethereum Foundation uses an octahedron diamond as its visual brand logo, typography communities and developers adopted the Greek uppercase letter Xi (Ξ, U+039E) as a text glyph because its four horizontal bars resemble a stylized 'E' reflecting decentralized layer architecture. Note that Ξ is an ordinary Greek alphabet character, not a dedicated Unicode currency mark.
