satoshivault

SatoshiVault is a fully offline mnemonic management tool designed to help users keep their crypto assets private and secure. It supports BIP39 mnemonic generation and validation, and can derive a complete set of addresses with a single tap — including four BTC address types (Legacy, Nested SegWit, Native SegWit, and Taproot), EVM multi-chain addresses (Ethereum, BNB Smart Chain, Base, Polygon, Arbitrum, Optimism, and over a dozen more networks), TRON (TRX), and Solana (SOL). Each address is paired with a scannable QR code for convenient receiving or verification. All computations happen locally on the device; mnemonics and private keys are never uploaded. The app also provides password protection, lockout after repeated wrong attempts, full history management (single or bulk deletion, one-tap mnemonic copy), 18 built-in languages, and enforced update reminders at the 90-day and 180-day marks. It is a dependable, privacy-first vault for long-term crypto ownership.
