Coinone is a South Korean cryptocurrency exchange founded in 2014, operating under the Korean name 코인원 (Coinone) with its official website at coinone.co.kr.[1] The brand’s visual identity was developed by Korean designers Chamin Hong and Ruth Seok, who created a distinctive blue-and-white gradient system for the blockchain trading platform.[2]

Design and History

The Coinone brand identity was designed by Chamin Hong and Ruth Seok, with the project documented in design showcases around 2020.[3] Ruth Seok worked as a brand designer at Coinone in Seoul, South Korea, during the period the identity was created.[4]

The identity is described in design publications as a blue-and-white gradient visual system, noted for its strong visual presence and comprehensive brand extensions.[2] The design has also been featured in roundups of minimalist logo work, where it is cited as an example of a brand identity built on simple, scalable forms.[5]

Meaning and Symbolism

Documented symbolism for the Coinone mark is limited. The identity relies on a typographic wordmark treatment, placing the brand name at the center of the visual system. [2]

Typography and Design

The Coinone wordmark uses a clean sans-serif letterform, consistent with the minimalist approach documented in design reviews of the identity.[5] The full identity system includes extensive brand applications, with the gradient and wordmark carried across digital and print touchpoints.[2]
