What MynaWallet does
MynaWallet Inc. (マイナウォレット株式会社) is a Tokyo-based Web3 fintech startup that operates a digital asset wallet linked to Japan's My Number Card national identity system. The company was founded on June 26, 2023 (originally as a42x Inc. before rebranding in December 2024) and is headquartered in FINOLAB, Otemachi, with a headcount of 1–10 employees led by CEO Tachibana Hiroyuki (橘博之). The core product, MynaWallet, is a consumer wallet app available on iOS and Android that uses My Number Card NFC authentication via the Japanese Public Key Infrastructure (JPKI) to perform KYC and enable Web3 access. The technical stack includes Account Abstraction (ERC-4337), Zero Knowledge Proofs for privacy, sponsored gas fees through a Paymaster, and multi-chain support across Ethereum, Polygon, Avalanche, Base, Optimism, and Arbitrum. The company also operates a KYC-verified Mini Apps Platform for third-party service distribution.
The business model centers on a free consumer wallet with planned monetization through MynaPay (an in-development payment solution), QR code payment functionality, and platform fees from the Mini Apps ecosystem. Strategic partnerships span crypto-native firms (Coincheck Group, JPYC, Coinbase/Base), major payment networks (Sumitomo Mitsui Card, JCB, Digital Garage), regional financial institutions (Resona Holdings, Shizuoka Financial Group), and hardware developers (Sharp Corporation). The company has achieved ISO/IEC 27001:2022 certification (April 2025) and JPKI Platform Operator Ministerial Approval (October 2025), and has raised ¥200M (~US$1.3M) in seed funding from gmjp holdings and Coincheck Group in June 2025. Active pilots include an education deployment with Chiba Institute of Technology covering 240 students and a local government initiative with Yamakoshi District in Nagaoka City.
Revenue mechanics are not yet disclosed; the company is pre-monetization with general availability of the consumer app launching in July 2026 and MynaPay still in development. Customer concentration risk is moderate given the partnership-mediated revenue model rather than direct enterprise or SMB sales.

MynaWallet product offering
Product offeringCore offering
MynaWallet is a non-custodial digital asset wallet that uses Japan's My Number Card and JPKI (公的個人認証サービス) for identity verification. Users tap their My Number Card on a smartphone to create a KYC-verified wallet without seed phrases or pre-installed apps, enabling them to send/receive tokens and stablecoins, manage NFTs, and access Web3 services across Ethereum, Polygon, Avalanche, Base, Optimism, and Arbitrum. The company is also developing MynaPay for NFC tap and QR stablecoin payments at retail locations.
Product overview
MynaWallet offers a suite of products centered on the マイナウォレット (MynaWallet) digital asset wallet — a non-custodial KYC-enabled wallet that turns Japan's My Number Card into a web3 wallet via NFC tap. The core マイナウォレット app connects to multiple blockchain networks (Ethereum, Polygon, Avalanche, Base, Optimism, Arbitrum) and supports tokens, stablecoins, and NFTs. Over this core wallet, the マイナペイ (MynaPay) module adds QR code and NFC tap payment capabilities for in-store stablecoin settlements. A ミニアプリ (Mini Apps) platform enables third-party services to embed within the MynaWallet app, building on its KYC-verified user base. Together, the products form a vertically integrated stack: My Number Card authentication → non-custodial wallet → payment rails → third-party service ecosystem.

MynaWallet competitors and assessment
Company assessmentDirect peers
- Magic Labs: Wallet/identity infrastructure offering email-based social recovery and embedded wallets for Web3 apps. Comparable to MynaWallet in pursuing passwordless, recovery-friendly onboarding flows and in serving as a wallet SDK for third-party services via mini-app patterns.
- MetaMask (Consensys): The leading self-custodial Web3 wallet globally, supporting Ethereum and multiple EVM chains with seed phrases and now exploring smart account features. Directly comparable to MynaWallet in core function (non-custodial digital asset management, multi-chain) but differs in authentication mechanism (seed phrase / hardware / social recovery vs. My Number Card JPKI) and in KYC posture.
- Phantom: Consumer-first Web3 wallet initially focused on Solana and now multi-chain, with built-in swap, staking, and fiat on-ramp. Comparable to MynaWallet in consumer UX-first positioning and multi-chain support, but without a government-ID authentication mechanism or KYC-verified user layer.
- Safe (formerly Gnosis Safe): Smart contract wallet built on Account Abstraction that pioneered multisig and now social-recovery flows for institutions and DAOs. Closest comparable to MynaWallet in AA-based account architecture and recovery mechanisms, though Safe targets crypto-native users rather than government-ID-verified consumers.
- Privy: Embedded wallet infrastructure for developers, providing turnkey self-custodial wallets with social login and AA-based flows. Closely comparable to MynaWallet's planned SDK/API mini-app platform approach, targeting developers who want to embed wallet functionality without building it from scratch.
- Trust Wallet: Mobile-first non-custodial wallet with broad chain support (EVM and non-EVM) and in-app dApp browser. Comparable to MynaWallet as a mobile-first multi-chain non-custodial wallet targeting mainstream consumers, though without government-ID authentication or KYC at the wallet layer.
Regional players
- bitFlyer: Major Japanese cryptocurrency exchange with broad retail and institutional coverage in Japan. Comparable as a regulated Japanese crypto venue that could either partner with or compete against MynaWallet by adding wallet features, and serves as a benchmark for Japanese crypto regulatory expertise.
- SBI VC Trade: Cryptocurrency exchange subsidiary of SBI Holdings, one of Japan's largest financial conglomerates. Comparable as a domestic Japanese crypto venue with deep financial-institution ties, capable of building wallet infrastructure that competes with or complements MynaWallet's regional-bank distribution strategy.
Emerging players
- Dynamic: Wallet-based authentication and embedded wallet platform enabling login with Web3 wallets and email/social. Comparable to MynaWallet's authentication-and-mini-app platform thesis, though Dynamic focuses on using wallets as identity for apps rather than issuing KYC-verified wallets backed by national IDs.
Broad incumbents
- Coincheck Group: Japan's leading cryptocurrency exchange by app downloads (six consecutive years) and a strategic investor in MynaWallet's seed round. Comparable as the dominant Japanese on-ramp to crypto assets and a natural distribution partner, while operating as a hosted VASP rather than a non-custodial wallet.
