UTON Encrypted Hardware Wallet is the world's first open source project based on Ubuntu system with HD wallet technology. The cold wallet adopts a hot and cold separation scheme: cold end builds transactions and signatures, and hot end broadcasts transactions. The background service is implemented using Node.js, which uses non-blocking I/O processing and event-driven to effectively solve high concurrency problems.
