Coincheck and KDDI Form Business Alliance!
PR TIMESCoincheck, Inc. announced that the conclusion of a business alliance agreement with KDDI CORPORATION has been completed.
In addition to telecommunications services, KDDI operates the smartphone payment service "au PAY," which has approximately 39.67 million members, giving it one of the leading customer bases in Japan in the financial payments field.
On the other hand, Coincheck provides Japan's largest customer base and a wide range of services as a crypto asset exchange service provider.
By combining the strengths of both companies, they state that it will be possible to expand access to digital assets, including crypto assets, for users in the au economic zone.
Through this alliance, they mention that they will aim for the creation of opportunities for more users to access digital assets in their daily lives, including collaboration with services such as au Jibun Bank and Ponta Points.
As the first initiative, a campaign for users who open a Coincheck account via au-related services will be implemented in the near future.
New Company "au Coincheck Digital Assets" Is Established
The new company, au Coincheck Digital Assets, was established with the purpose of realizing an environment where digital assets, beginning with crypto assets and stablecoins, can be used more familiarly, centering on a non-custodial wallet provided as a mini-app within au PAY.
Conventional non-custodial wallets had issues making it difficult for them to spread to users other than those well-versed in crypto assets, due to barriers such as initial introduction hurdles like creating a wallet, and complex processes like purchasing crypto assets at an exchange and sending them to the wallet.
At au Coincheck Digital Assets, by combining KDDI's touchpoints with consumers and Coincheck's know-how regarding crypto assets, they state that they will promote the creation of a new user experience that seamlessly connects crypto asset storage to daily utilization in the au economic zone.

New financial and economic mechanisms utilizing crypto assets and tokens based on blockchain are being formed globally.
In the midst of this major trend of transformation, we established au Coincheck Digital Assets to realize an environment where anyone can easily and safely touch digital assets.
While crypto assets and stablecoins have extremely large potential, there are certain hurdles to starting their use, and many customers find them difficult.
We want to move toward a society where these new values are not just for a limited number of people, but are used naturally in daily life.
By combining the customer base possessed by KDDI and au Financial Holdings with the digital asset expertise held by Coincheck, we will provide the flow of new value brought by blockchain in a form that anyone can use naturally.
