It can securely store a 12-word seed phrase, which is a common option for most hardware wallets and the default for many non-custodial software and Lightning wallets, or passwords up to 64 characters in length. Supported wallet brands include hardware wallets (Blockstream, Bitbox, Ledger, KeepKey, Coldcard, Passport by Foundation), software wallets (Green, Electrum, Exodus, Electrum, Samourai, Trust Wallet), and Lightning wallets (BlueWallet, Wallet of Satoshi, Phoenix, Zap, Breez). All of these wallets are non-custodial, meaning you retain full control of your private keys and seed phrases, making them compatible with Seed12 for securely storing and recovering your sensitive information. With Seed12, you can store any password up to 64 characters long. The Backup Core set includes both uppercase and lowercase letters. If you need numbers or special characters, you can purchase them separately. This approach helps us reduce waste, allowing you to buy only the modules you truly need. The letter tiles, separators, and fasteners are compatible between the Seed12 and Cryptosteel Capsule. All of these components have been redesigned for Seed12 and may look slightly different, but they will definitely fit both devices. However, the tiles from the Cassette are shaped differently and are tailored for a different storage system, so they are not compatible with the Capsule or Seed12. You can use a 12-word seed phrase with any hardware wallet that supports the BIP39 standard. These wallets, including Trezor, BitBox, Ledger, and Blockstream, are compatible with 12, 18, or 24-word phrases. You can easily restore a 12-word seed phrase on any BIP39-compatible hardware wallet, such as Trezor, BitBox, Ledger, or Blockstream, even if the wallet was initially set up with a 24-word seed.
