Overview

OneGate is a modern wallet for the Neo N3 ecosystem. It focuses on providing a smooth cross-platform experience for wallet creation and import, asset management, NFT viewing, dApp interaction, and authentication workflows.

Built with C#, XAML, and .NET MAUI 10, OneGate is designed to share a single codebase across multiple platforms while still keeping a native app experience.

Features

• Create a new wallet locally
• Import wallets via mnemonic, WIF / raw private key, or NEP-2
• Manage NEO / GAS and other NEP-17 assets
• View and transfer NEP-11 NFTs
• Built-in dApp launcher and wallet authorization flow
• Opt-in encrypted DApp remote debugging interface for trusted remote debuggers on the same LAN, with QR pairing, persistent trust, explicit approval and optional method-specific results for requests selected by OneGate policy, logs, traces, JavaScript evaluation, and visible-WebView screenshots
• Support for NEP-20, NEP-21, and related dAPI workflows
• Support for neo: and neoauth: deep-link flows
• QR code scanning for wallet and dApp actions
• Address book / contacts support
• Biometric protection for sensitive operations
• Screen-security handling for private-key and password related flows
• Multi-language UI support
• Light / dark theme support

Remote debugging is hidden behind Developer Tools and is off by default. Its app-side pairing and session protocol is not tied to a specific debugger: the OneGate Codex plugin provides the first compatible remote debugger implementation, while other debugging tools can implement the same interface in the future. Real-app sessions accept HTTPS DApp URLs only. In a remotely started DApp session, explicit approval from the trusted remote debugger replaces the ordinary in-app confirmation on every network. Disabling Developer Tools disconnects remote debuggers and closes remote sessions without silently deleting the user’s trust list.
