Your Myna Card, Your Wallet.
MynaWallet is a digital wallet that turns Japan’s My Number Card into a Web3 wallet. Users can create an account and sign in by simply tapping the card with a smartphone (NFC) or a reader, without managing private keys or complex passwords. It supports managing crypto assets, stablecoins, NFTs, and digital IDs, and leverages the government-backed Public Key Infrastructure (JPKI) for strong identity verification. It also uses zero-knowledge proofs to enable privacy-preserving, selective disclosure of attributes, and aims for fraud-resistant usage.
