What's New • Organize with tags — add custom tags to any wallet and filter your list instantly • Blockchain networks — assign a network to each wallet with recognizable chain icons (Ethereum, Bitcoin, Solana, Polygon, BNB, Avalanche, Arbitrum, Optimism, Base, and more) • Smarter seed entry — wallets are now validated against the BIP-39 standard (word count, wordlist, and checksum) so you catch typos before saving • Duplicate detection — get warned if you try to save a recovery phrase you've already stored • Encrypted backup & restore — export your wallets to a password-protected, encrypted file and import them back on any device • Add notes to any wallet for extra context • Refreshed design throughout — redesigned Home, wallet details, and add-wallet screens with polished light and dark themes Thanks for using CryptoWarden! If the app helps keep your seed phrases safe, we'd love a rating.
