what's UN Wallet?
UN Wallet is a compact, self-custodial hardware wallet shaped like a standard bank card, weighing just 23 grams. It connects directly to smartphones via NFC tap, enabling multichain operations such as token swaps on BNB Chain, staking on Solana, bridging on Arbitrum, or minting on Base without cables, apps, or intermediaries. Private keys remain securely on the card, ensuring full user control with direct blockchain transactions. The design prioritizes privacy by avoiding databases or data collection, making it suitable for everyday crypto management across multiple ecosystems.
UN wallet now supports Polygon blockchain with send/receive and cross-chain swap functionality.
