SeedArk is a fully offline BIP-39 mnemonic vault for storing recovery words from hardware wallets, cold wallets, and self-custody setups. It is not a wallet. SeedArk does not derive addresses, connect to blockchain RPC endpoints, send transactions, or provide buying, selling, swapping, lending, staking, or any financial operation. It does one job: store your mnemonics and optional passphrases as encrypted local records, so you can look them up when you need them. Core features • Fully offline by design: no account, no cloud sync, no remote server • Supports 12 / 15 / 18 / 21 / 24-word BIP-39 English mnemonics • Generate new mnemonics on device or enter existing ones manually • Validate BIP-39 wordlist membership and checksum during entry • Store optional passphrases with UTF-8 hex display for byte-level checking • Organize multiple records with names, chain tags, and notes • Search names, tags, and notes while excluding sensitive seed data • Unlock with an app password and optional Face ID fast path • Auto-lock after backgrounding or inactivity • Disable copy and share menus on sensitive views • Add defenses for third-party keyboards, dictation, screenshots, screen recording, and app switching • Export the full vault as an encrypted .wwbk file for migration or secondary backup Security model SeedArk encrypts the local vault with AES-GCM through Apple CryptoKit and derives password keys with Argon2id through swift-sodium / libsodium. Keychain items are limited to this device and never synchronize through iCloud Keychain. Data files use complete file protection and are excluded from system backups. SeedArk is not meant to replace your paper or steel backup. Your handwritten offline copy should remain the ultimate source of truth. SeedArk is a second layer for daily lookup, organization, migration backup, and local encrypted safekeeping. If you need a connected wallet, market data, trading, address derivation, or on-chain interaction, SeedArk is not that tool. If you need a restrained offline vault dedicated to mnemonic storage, that is exactly what it is built for.
