unsu is a crypto wallet that works in any browser. No apps, no extensions, no accounts.
UNSU offers a streamlined and highly accessible browser-based cryptocurrency wallet designed for effortless everyday use across many networks (i.e. Ethereum, Base, and Arbitrum, Arc networks).
Operating entirely client-side, it requires no downloads, browser extensions, accounts, or logins, while keeping your private keys and funds securely under your control within the browser. Users can simply visit unsu.com, enter their secret recovery phrase, and immediately send or receive digital assets using intuitive ENS names such as alice.unsu.eth, traditional addresses, or convenient QR codes for quick scanning and sharing.
Highly configurable by design, UNSU allows developers and advanced users to easily add new chains or custom assets by editing the network configuration in the source code, and it supports bridging assets between supported chains for seamless cross-network transfers.
This makes UNSU particularly practical for mobile phones and any device with a modern web browser, enabling smooth transactions whether at home, on the go, or introducing newcomers to cryptocurrency without technical barriers. Available on both mainnet and testnet for safe practice, it serves as an ideal lightweight solution for regular transfers and interactions rather than long-term cold storage.
The project is fully open source under the MIT license at github.com/anton-io/unsu, with a clean, modern web implementation that supports easy local development and community contributions. For those seeking frictionless crypto interactions that feel as simple as using any web application, UNSU delivers a professional, reliable, and inclusive experience directly in the browser.
UNSU is a elegantly minimalistic cryptocurrency wallet engineered for universal accessibility, built with a lean stack that prioritizes simplicity, security, and portability. At its core, the frontend leverages vanilla JavaScript combined with ethers.js for client-side wallet operations, deriving private keys directly from a secret recovery phrase using secure keccak256-based methods entirely within the browser, ensuring private keys never leave the user's device.
This architecture, paired with a lightweight Flask Python backend for serving static files and proxying ENS resolution, results in exceptionally minimal dependencies, allowing the wallet to run seamlessly on any modern web browser, including mobile phones and tablets, without installations or extensions.
ENS integration powers intuitive address handling by enabling human, readable names like alice.unsu.eth for both sending and receiving, with robust resolution and reverse lookup supported through an external gateway API and local fallback for reliability.
The application is highly configurable: network definitions, RPC endpoints, chain IDs, and supported assets are centralized in the frontend configuration, making it straightforward for developers to add new chains or custom tokens. Bridging capabilities between supported networks like Ethereum, Base, and Arbitrum are facilitated through ethers.js transaction handling and can leverage emerging interoperability tools such as Circle's Arc ecosystem features and Arc Kit for enhanced cross-chain asset transfers.
This design philosophy—minimal dependencies and a focus on browser-native execution—ensures UNSU operates reliably anywhere with web access, serving as a practical, everyday tool for quick, frictionless transactions on mainnet or testnet. Fully open source under the MIT license at github.com/anton-io/unsu, it invites contributions while maintaining a professional, secure foundation for inclusive cryptocurrency adoption.
