Coincheck is a Japanese cryptocurrency exchange that was founded in 2014 by Koichiro Wada and Yusuke Otsuka. The exchange was created to provide a platform for buying and selling cryptocurrencies, including Bitcoin, Ethereum, and Ripple, among others. Coincheck quickly became one of the largest cryptocurrency exchanges in Japan, with over 1.7 million registered users by 2018.

Coincheck is headquartered in Tokyo, Japan, and has become a major player in the cryptocurrency industry. The exchange has been praised for its user-friendly interface and its commitment to security, with the company implementing a number of measures to protect its users' funds. However, Coincheck has also faced its fair share of challenges, including a major hack in 2018 that resulted in the loss of over $500 million worth of cryptocurrency.

Despite this setback, Coincheck has continued to grow and expand its services, with the exchange now offering a range of products and services, including a mobile wallet, a trading platform, and a cryptocurrency lending service. The company has also been working to improve its security measures, with the goal of becoming one of the most secure cryptocurrency exchanges in the world.
