Package: slip39
Creating Ethereum, Bitcoin and other accounts is complex and fraught
with potential for loss of funds.A BIP-39 seed recovery phrase helps, but asinglelapse in security
dooms the account (and all derived accounts, in fact).  If someone finds
your recovery phrase (or you lose it), the accounts derived from that
seed are /gone/.The SLIP-39 standard allows you to split the seed between 1, 2, or more
groups of several mnemonic recovery phrases.  This is better, but
creating such accounts is difficult; presently, only the Trezor supports
these, and they can only be created "manually".  Writing down 5 or more
sets of 20 words is difficult, error-prone and time consuming.Hardware Wallet "Seed" ConfigurationYour keys, your Bitcoin.  Not your keys, not your Bitcoin.---Andreas AntonopoulosThepython-slip39project (and theslip39-app) exists to assist in the safe creation,
backup and documentation of Hierarchical Deterministic (HD) Wallet seeds and derived accounts,
with various SLIP-39 sharing parameters.  It generates the new random wallet seed, and generates
the expected standard Ethereum account(s) (atm/44'/60'/0'/0/0by default) and
Bitcoin accounts (at Bech32 derivation pathm/84'/0'/0'/0/0by default), with wallet address and
QR code (compatible with Trezor and Ledger derivations).  It produces the required SLIP-39
phrases, and outputs a single PDF containing all the required printable cards to document the seed
(and the specified derived accounts).On an secure (ideally air-gapped) computer, new seeds can /safely/ be generated (withouttrusting this program) and the PDF saved to a USB drive for printing (or directly printed without
the file being saved to disk.).  Presently, =slip39= can output example ETH, BTC, LTC, DOGE, BSC,
and XRP addresses derived from the seed, to /illustrate/ what accounts are associated with the
backed-up seed.  Recovery of the seed to atrezor-model-tis simple, by entering the mnemonics
right on the device.We also support the backup of existing insecure and unreliable 12- or 24-word BIP-39 Mnemonic
Phrases as SLIP-39 Mnemonic cards, for existing BIP-39 hardware wallets like theledger-nano,
etc.!  Recover from your existing BIP-39 Seed Phrase Mnemonic, select "Using BIP-39" (and enter
your BIP-39 passphrase), and generate a set of SLIP-39 Mnemonic cards.  Later, use the SLIP-39 App
to recover from your SLIP-39 Mnemonic cards, click "Using BIP-39" to get your BIP-39 Mnemonic
back, and use it (and your passphrase) to recover your accounts to your Ledger (or other) hardware
wallet.Output of BIP-38 or JSON encrypted Paper Wallets is also supported, for import into standard
software cryptocurrency wallets.The SLIP-39 App for Generation and BackupDownload the SLIP-39 App fromslip39-downloadfor Windows (.msi) or macOS (.dmg).The Graphical User Interface (GUI) also supports Linux:$ python3 -m pip install slip39[gui]
