About this app

Merge Wallet is a self-custodial mobile wallet for Rootstock (RSK), the Bitcoin-secured smart contract platform. Take full control of your RBTC, RIF, USDRIF, and other RSK-based tokens with enterprise-grade security directly on your mobile device.

Key Features:
• Self-Custodial — You control your private keys. Your recovery phrase is encrypted and stored exclusively on your device. Merge never has access to your funds.
• RBTC & ERC-20 Support — Send, receive, and hold RBTC alongside RSK ecosystem tokens including RIF and USDRIF. Built-in token detection displays known assets automatically.
• NFT Tracking — Import and monitor your RSK-based NFTs (ERC-721). Check balances and ownership at a glance.
• PIN & Biometric Security — Protect your wallet with a 4-digit PIN secured by AES-256-GCM encryption. Optional biometric unlock for quick access.
• Recovery Phrase — 12/24-word BIP39 mnemonic backup. Import existing wallets or generate new ones. Clear seed-from-memory after backup confirmation.
• Transaction History — Browse recent transactions with status indicators. Tap to view on the RSK block explorer.
• Network Switching — Seamlessly switch between RSK Mainnet (Chain ID 30) and Testnet (Chain ID 31) for development and testing.
• Dark Mode — System, Light, or Dark theme support throughout the entire interface.
• Currency Conversion — Display balances in 12 fiat currencies with live CoinGecko price feeds.
• QR Codes — Generate receive QR codes and copy your address with one tap.
• Offline Detection — Graceful handling of network interruptions with clear user feedback.

Security Architecture:
• Keys derived via BIP39 mnemonic with BIP44 path m/44'/60'/0'/0/0
• Private keys never exposed to the JavaScript runtime unnecessarily
• Encryption key cleared from memory on app pause
• Native AES-256-GCM encryption plugin for PIN storage
• Transaction signing occurs internally — private key never leaves the secure module

Built with React 19, Vite 6, Tailwind CSS 3, and Capacitor 8 for a native mobile experience powered by RSK infrastructure.
