Kaspa Browser

KaspaBrowser is an Android web browser and decentralized network gateway built with Kotlin and Jetpack Compose (Material 3). It unifies standard Web browsing, decentralized peer-to-peer mesh discovery, cryptographic identity management, on-device local node hosting, and native Kaspa BlockDAG (KAS) wallet utilities into a streamlined mobile client.

KaspaBrowser is built on top of a Dual-Stack Hybrid Rendering Engine. It combines Android's hardware-accelerated Blink/Chromium WebCore with custom protocol interception layers, decentralized domain resolvers, local micro-node routing, and content shields.

Engine Specifications Core Rendering Engine: Android System WebView (Chromium/Blink WebCore with V8 JavaScript engine & Skia 2D rendering). Protocol Interception Layer: Custom WebViewClient request interceptor (shouldOverrideUrlLoading & shouldInterceptRequest) catching Web3 protocols (ipfs://, kas://, mesh://, dweb://, .kas, .hns, .eth, and P2P CID targets). Network Pipeline: Asynchronous OkHttp3 client with pure HTTP/3 (QUIC over UDP) transport layer, 0-RTT handshakes, zero head-of-line blocking, and connection migration (HTTP/2 removed). Decentralized DNS Engine: Multi-chain DoH & ledger resolver querying Handshake (HNS) PoW root chain, Kaspa Block DAG (KNS), ENS (.eth), EmerDNS, and OpenNIC directly. Cryptographic Verification Engine: Local in-browser SHA-256 message digest calculator certifying incoming payload streams as VERIFIED_TAMPER_PROOF and blocking tampered packets. Local Mesh Seeding Engine: Room SQLite database engine (AppDatabase / ContentDao) storing content-addressed blocks with isSeeding = true for peer mesh seeding and zero single point of failure during server outages. JavaScript & Web3 Bridge: @JavascriptInterface bridge enabling zero-knowledge account identity injection, Web3 dApp RPC calls, and local Kaspa wallet signing without exposing private keys. Privacy & Content Shield Engine: Real-time URL blocklist evaluator inspecting incoming DOM resources against ad-trackers and telemetry scripts before passing sanitized streams into the rendering pipeline.

🌟 Key Features 🌐 1. Dual-Stack Gateway & Web Browser Unified Protocol Handler: Seamlessly navigates standard web addresses (http://, https://) and decentralized Web3 protocols (ipfs://, hyper://, .kas, .mesh, and custom local peer endpoints). Dual-Stack DNS & Mesh Resolver: Automatically resolves local and peer nodes on local mesh networks before routing out to public gateways. Modern Web Engine: Powered by an integrated Android WebView equipped with safe file picker fallbacks, cookie isolation, progressive Web App (PWA) manifest auto-detection, and customizable desktop/mobile User Agents. Offline & Cache Mode: Offline browsing cache with granular cache-clearing controls. 🛡️ 2. Cryptographic Identity & Key Management Decentralized Accounts: Create, import, and manage hierarchical deterministic (HD) seed phrases and keypairs. Ed25519 & Secp256k1 Cryptography: Hardware-backed key derivation with cryptographic hashing (SHA-256, Blake2b). Account Backup & Export: Safe export of private keys and recovery phrases with PIN and biometric protection. 💰 3. Native Kaspa BlockDAG (KAS) Wallet Real-Time DAG Explorer & Balances: Query live UTXO balances, sompis denominations, and transaction histories across mainnet and testnet endpoints. Fast Transactions: Compose, sign, and broadcast KAS transactions directly to public and local Kaspa nodes. QR Code Scanner & Address Validation: Built-in address syntax validator for kaspa: and kaspatest: bech32 formats. 📡 4. P2P Mesh Radar & Local Node Hosting Live Mesh Radar: Discovers nearby nodes, peers, and local web services over Wi-Fi Direct, Local Area Networks (LAN), and NSD (Network Service Discovery). On-Device Micro Daemon: Host lightweight local web pages, decentralized documents, or P2P data packets directly from your phone. Peer Latency & Routing Metrics: Real-time ping, hops, bandwidth consumption, and signal strength auditing. 📊 5. Real-Time Traffic Audit & Privacy Shield Data Usage Analytics: Monitor upstream and downstream bandwidth in real time. Tracker & Script Protection: Built-in content shielding to mitigate intrusive tracking and reduce mobile data overhead. Live Traffic Logs: Detailed ledger of intercepted network calls, DNS queries, and decentralized gateway lookups. 📱 6. PWA Launcher & Desktop Integration Zero-Install Web Apps: Pin decentralized dApps and standard web apps directly to the Android Home Screen using Android Pin Shortcut APIs. Dynamic Icons & Standalone Viewing: Launches installed web apps in dedicated immersive views.
