Mitilena Air

Turn your Mitilena NFC card into a true hardware wallet — completely offline.

Mitilena NFC is a companion application designed for maximum security. It operates in an absolute digital vacuum: the app requires NO internet permission (verified in the Android Manifest) and has zero network traffic. Your private keys and mnemonic phrases never touch the internet, servers, or cloud storage.

This app requires a Mitilena license to operate (activated via NFC card, QR code, or manual entry).

KEY FEATURES:

🔐 WRITE TO CARD (Keys Mode)

Generate a secure BIP-39 mnemonic phrase (12 words).

Encrypt your mnemonic with a custom 6-12 character password using military-grade AES-256-CBC encryption (PBKDF2 with 100,000 iterations).
Write the encrypted data directly to your Mitilena NFC card as an NDEF text record.
Option to permanently lock the NFC card (read-only mode).

📲 READ CARD (Keys Mode)

Tap your NFC card and enter your password to instantly decrypt your data.
Derive addresses and private keys for 16 supported blockchains directly from the mnemonic.
Easily copy your addresses and keys using the secure Clipboard API.

✍️ TRUE OFFLINE SIGNING (Sign Mode - Requires Full License)

Prepare: Load an unsigned transaction (via text, QR code scan, or QR image upload). Verify the from/to addresses, amount, and network.
Sign: Enter your private key (via text, QR, NFC tap, or mnemonic derivation). The app signs the transaction offline and generates a signed hash and QR code.
Broadcast: Scan the signed QR code with your online wallet to safely broadcast the transaction.

🌐 SUPPORTED BLOCKCHAINS:
Full support for Bitcoin (UTXO), Ethereum (EVM), BSC, TRON, Solana, TON, XRP, Litecoin, Dogecoin, Zcash, Monero (key images), Ethereum Classic, Arbitrum, Polygon, Optimism, and Base.
(Note: L2 networks map to Ethereum during derivation).

UNCOMPROMISING SECURITY:

No Internet Access: Physically impossible to leak data.
Strong Encryption: AES-256-CBC and PBKDF2 (100k iterations).
License Verification: Ed25519 signature validation.

Standardized: Full compliance with BIP-39, BIP-32, and BIP-44.

Zero Trust: No accounts, no cloud, no tracking.
