Problem
Cryptocurrency holders often need to manage assets across disparate blockchains while protecting private keys from phishing, password leaks, and single-point failures. Existing wallets typically rely on password‑based authentication and limited chain support, creating friction for users who want to engage in DeFi, NFT, and cross‑chain activities securely.
Solution
Open Wallet delivers a self‑custodial, multi‑chain wallet that combines Multi‑party Computation (MPC) key management with password‑less passkey authentication. The MPC protocol distributes secret shares across independent nodes, eliminating the need for a single secret stored on the device, while biometric verification adds an additional layer of user‑level protection. The wallet natively supports major EVM networks (Ethereum, Polygon, Optimism, Arbitrum, Base, Linea) as well as Bitcoin, TON, and Tron, enabling seamless asset transfers without external bridges. Integrated DeFi modules let users stake, farm, and provide liquidity, and an NFT gallery consolidates tokenized collectibles in one view. Real‑time portfolio analytics aggregate price feeds and on‑chain balances, delivering up‑to‑date performance metrics within the app. A lightweight SDK provides one‑click connection to dApps, preserving the user experience across the decentralized web.
Target Audience
The primary users are crypto‑savvy individuals, DeFi participants, and NFT collectors who require a secure, self‑custodial wallet capable of managing assets across multiple blockchains without compromising usability.
