- To recover your Bitcoin wallet without a BitBox01, enter the wallet backup text and password in the above boxes, click ‘generate’ and import the recovery key into the Electrum software wallet.
- To recover Ethereum without a BitBox01, enter the wallet backup text and password in the above boxes, click ‘generate’ and enter an Ethereum private key into MyEtherWallet. The order of private keys corresponds to the order of public addresses when ‘viewing’ a wallet in MyEtherWallet.
- To load your own wallet into a BitBox01, put the PDF file on the micro SD card inside a folder named ‘digitalbitbox’ in the root directory. Then, insert the SD card into the BitBox01, and load your wallet using the desktop app. High quality randomness is crucial! Otherwise a thief may be able to guess your key and take your coins.
- A wallet is generated from the backup text and password using a modified BIP39 procedure. In particular, PBKDF2 strengthening is done twice (22,528 total rounds) for stronger protection.
- Standard wallet addresses are generated following the BIP32 and BIP44 specifications.
- The BIP32 extended master private key is m.
- BIP 44 specifies the following standard:
- m / purpose’ / coin_type’ / account’ / change / address_index
- Purpose is set as follows:
- Legacy (P2SH) = 44’
- Segwit (P2PSH) = 49’
- Native Segwit (P2WPKH) = 84’
- Coin_type is set in accordance to SLIP-44:
- Bitcoin = 0
- Testnets = 1
- Litecoin = 2
- Ethereum = 60
- BitBoxApp currently only supports a single account, therefore wallets created via the BitBoxApp will use 0 for the account field.
- Wallets created with other wallet software have a different account field number.
- 0 for normal receive addresses
- 1 for internally generated change addresses
- Addresses are numbered from index 0 in sequentially increasing manner.
- The tool generates Ethereum keys m/44’/60’/0’/0/0 through m/44’/60’/0’/0/19.
