Minima Wallet is a native Android application for managing keys and interacting with the Minima blockchain network. No node required. Built with Material Design 3, Navigation Drawer navigation, and biometric protection. How it works Seed Phrase → [locally] → Private Key + Address │ ┌─────────────────────┼─────────────────────┐ ▼ ▼ ▼ Request balance Get unsigned transaction Broadcast signed wallet.minima.global wallet.minima.global transaction (API) (API) wallet.minima.global │ (API) ▼ [locally, no internet] Sign transaction with private key 🔐 The private key never leaves the device. Signing happens locally without transmitting the key over the network. Only public data is sent via API: address, balance, unsigned and signed transaction. Features - 💰 Wallet: View balance, generate cryptographic keys and addresses, show address QR code - 📤 Send: Send transactions with token selector, scan QR code (camera or image file) - 🌐 Explorer: Built-in blockchain explorer with back/refresh navigation - 🔒 FutureCash: Lock funds until a future date with time-lock scripts - 📈 Maximize: Stake MINIMA for 1–12 months and earn guaranteed returns (0.5%–9%) - 🔑 Seed Phrase: Securely store and manage your seed phrase (BIP39) - ⚙️ Settings: Configure node URL, language (auto-detect system language) - 🔒 Biometrics: Fingerprint authentication on startup Working with API By default, the app uses the public API endpoint: https://wallet.minima.global/mdscommand_/cmd?uid=0xFFEEDD This UID is permanent and does not change. If the API URL field is left empty, this default endpoint will be used. To use your own API endpoint: 1. Make sure your server node has Public Wallet and MegaMMR enabled 2. Open the Public Wallet in your browser 3. Copy the full URL including the UID — it should look like: https://YOUR_IP:9003/mdscommand_/cmd?uid=YOUR_UID 4. Paste it into the Settings → API URL field ⚠️ Note: The UID will most likely change after a server restart. You will need to update the URL in the app settings. Example of a working API URL: https://spartacusrex.com:8888/mdscommand_/cmd?uid=0x12D2B61F...79C Working with Seed Phrase On first launch, you can enter a seed phrase for your wallet. A seed phrase can be any word, symbol, character, or combination of them — even a space counts as a valid phrase. - 🎲 You can generate a random 24-word phrase using the built-in generator - 💾 Press Save Phrase to store it encrypted with your fingerprint - 📝 Write your phrase down on paper! If you forget or lose it, nobody can recover it To view or change your saved phrase: 1. Go to Seed Phrase in the navigation menu 2. Authenticate with your fingerprint 3. Make changes if needed and press Save again 4. If no changes — simply navigate to the Wallet and continue using the app Working with Address The app works with one address number at a time. You can generate any address number associated with your seed phrase. - Address numbers range from 0 to 999,999,999 — that's how many deterministic addresses the app supports for a single phrase - 💡 Tip: Don't use excessively large address numbers to avoid confusion — keep it simple Security - No node required — the app works via the public API wallet.minima.global - Keys on-the-fly — private key is derived from the seed phrase each time and never stored - Offline signing — transactions are signed locally on the device, the key is never sent over the network - Seed phrase stored exclusively in Android Keystore encrypted storage (AES-256-GCM) - Key generation using SecureRandom (no java.util.Random) - Biometric authentication via BiometricPrompt - Cleartext traffic blocked via network_security_config.xml License This project is licensed under the MIT License.
