Jack Mallers

Jack Mallers is an independent software publisher best known for Zap, a cross-platform Lightning Network wallet designed to make Bitcoin micro-payments fast, inexpensive and accessible to non-technical users. Built on the open-source repository LN-Zap/zap-desktop, the application translates the complexity of channel management, invoice generation and node connectivity into a clean, wizard-driven interface that runs identically on Windows, macOS and Linux. Typical use cases range from everyday consumers who want to tip content creators or buy coffee with satoshis, to online merchants seeking near-instant settlement without charge-back risk, to developers prototyping Lightning-powered services that require reliable test-net or main-net wallets. The wallet supports both remote and local node connections, autopilot channel balancing, fee estimation, on-chain sweep functions and Tor routing, packaging the entire Lightning stack into a single downloadable executable so that newcomers can begin transacting within minutes while advanced operators retain full control over private keys and channel states. Although the GitHub project has entered maintenance mode, the codebase remains a reference implementation for intuitive Lightning UI/UX and continues to attract contributors who value privacy-first, self-custodial finance tools. Jack Mallers’ Zap wallet is available for free on get.nero.com; the site supplies the latest release through trusted Windows package sources such as winget, enabling one-click or batch installation alongside other open-source utilities.
