MetaMUI Wallet

A next-generation, post-quantum wallet for identity-powered digital finance.



MetaMUI Wallet is the official asset and identity wallet natively connected to the MetaMUI Blockchain. Designed for secure, identity-based digital finance, it brings together digital assets, decentralized identity, and verifiable credentials in one simple application.



Post-Quantum Security

MetaMUI Blockchain is powered by a post-quantum cryptographic architecture using Falcon-512 digital signatures, designed to protect digital assets and identities against emerging cryptographic threats, including those posed by future quantum computers.



MetaMUI Wallet provides a seamless migration path for existing users. Your existing MetaMUI address is preserved, while the underlying digital signature is upgraded from Sr25519 to Falcon-512. There is no need to create a new address or manually transfer your assets to a newly created wallet. This address-preserving cryptographic migration enables existing users to transition to post-quantum security with minimal disruption.



Identity-Powered Digital Finance

Create an identity-based wallet in minutes and securely manage your digital assets through the MetaMUI Blockchain.



MetaMUI Wallet supports Verifiable Credentials (VCs), enabling you to securely prove your identity and other credentials. These credentials can be used for digital notarization, authentication, authorization, and verifiable proof of real-world events.



Manage Your Digital Assets

Connect directly to the MetaMUI Blockchain and maintain full control over your digital assets. Send assets globally, manage your holdings, and access identity-powered financial services through a secure and easy-to-use wallet.



Human & AI Commerce

MetaMUI Wallet is also a gateway to the broader MetaMUI ecosystem, supporting multiple digital assets, decentralized applications, identity services, and emerging use cases for both human and AI-driven commerce.



Built with simplicity and security in mind, MetaMUI Wallet makes advanced blockchain and post-quantum technology accessible to everyone.
