MynaWallet and Coincheck Partner on Web3 Identity Verification Infrastructure
Coincheck has entered into a strategic partnership with MynaWallet, a company providing a web3 wallet solution utilizing the Japanese government-issued My Number Card.
Prior to this collaboration, Coincheck Group N.V., which is Coincheck’s parent company, made an investment in MynaWallet.
MynaWallet is currently developing a service called “MynaWallet,” which aims to allow anyone to manage digital assets—such as cryptocurrencies, stablecoins, NFTs, and digital IDs—safely, securely, and with ease. The service is built on a unique position that combines the My Number Card, Decentralized Identifiers (DIDs), Verifiable Credentials (VCs), and web3 wallet functionality. MynaWallet is expected to play a key role in driving web3 adoption in Japan through public-private sector collaboration.
Furthermore, MynaWallet has been participating from an early stage in working groups and councils led by the Digital Agency and the Cabinet Secretariat, thereby strengthening its coordination with institutions involved in policy formation.
As a leading crypto asset exchange in Japan, Coincheck is positioned at the forefront of web3 infrastructure implementation in the private sector. Against this backdrop, we intend to promote the co-creation of public web3 infrastructure in Japan by bridging institutional design and real-world private use cases through our collaboration with MynaWallet.
