Coincheck is a bitcoin wallet and exchange service headquartered in Tokyo, Japan, founded by Koichiro Wada and Yusuke Otsuka. It operates exchanges between bitcoin/ether and fiat currencies in Japan, and bitcoin transactions and storage in some countries worldwide.[1][2][3] In April 2018, Coincheck was acquired by Monex Group for 3.6 billion yen.[4]

History[edit]

Coincheck started in August 2014 and is operated by Coincheck, inc. (previously ResuPress, inc) (founded in 2012). As of August 2016, the exchange had over $160 million transactions per month.[5][6][7] There were then more than 2,200 merchants using their bitcoin payment solution, just in Japan.[8] Coincheck is a member of JBA (Japan Blockchain Association)[9] and is actively helping to build the Japanese bitcoin community's usage standards with the government.

In March 2016, the entertainment company DMM.com with a user-base of more than 19 million decided to use Coincheck's bitcoin payment processing solution.[10] Coincheck also partnered with SEKAI to support Chinese, Hong Kong, and Taiwan investors to buy Japanese real estate with bitcoin.[11][12] The company also supports the buying and selling of ether,[13] DAO,[14][15] LISK,[16][17] and Ethereum Classic.[18]

2018 hacking incident[edit]

In January 2018, Coincheck was hacked and approximately 500 million NEM tokens ($530 million) were stolen.[19][20] The currency was transferred through a total of nineteen accounts, one of which was found to have no connection with the hacker.[21]

The hack led two of Japan's crypto-currency trade groups to merge into a new self-regulatory organization.[22] The Financial Services Agency took administrative action by ordering Coincheck to improve its security practices,[23] but did not order the exchange to shut down out of a concern for the protection of its users.[24] Coincheck initially announced that it may not be able to compensate all users affected by the hack,[25] but then announced that it would repay all 260,000 users affected in Japanese yen using its own capital.[26]

The hack only involved NEM. Because the security breach was caused by the lack of strong security measures of Coincheck, the NEM development team refused to conduct a hard fork. Instead NEM is creating an automated tagging system. This automated system will follow the money and tag any account that receives tainted money.[22]
