Your past and future transactions, without being able to Wallets, where a wallet can import information about all This feature is commonly called watch-only To generate addresses offline, without having access to the One the coolest features of HD wallets is that it's possible res1: Boolean = true Generating new addresses without having access to the private key Your funds can be recovered from a secret phrase. segwitPath: SegWitHDPath = m/84'/0'/0'/0/0 // alternatively: val otherSegwitPath = Your private keys are encrypted and never leave your computer. xpub: ExtPublicKey = zpub6jftahH18ngZxzQCtNXS5q3ATT29MmsQHRH7jzhaJqCpfLxSgGWo1n7uKHLEDwPgTXuoBgPZXHYs7LEghsBGp6NVhppgtwcLL9EWzageFWi // you can now use the generated xpriv to derive further // private or public keys // this can be done with BIP89 paths (called SegWitHDPath in bitcoin-s) val segwitPath = omString( "m/84'/0'/0'/0/0") The blank label is needed to pass the true/false flag. To do so use the command importprivkey false for each key and importprivkey true for the last one.xpriv: ExtPrivateKey = Masked(ExtPrivateKeyImpl) val xpub = xpriv.extPublicKey While adding multiple keys you may want to avoid a time consuming rescan after each key. bip39Seed: BIP39Seed = Masked(BIP39SeedImpl) val xpriv = omBIP39Seed( ExtKeyVersion. So you could have as many wallets // from the same seed as you'd like, by simply giving them // different passwords. ![]() all MnemonicCode instances will give you a // valid BIP39 seed, but different passwords will give // you different seeds. MnemonicCode.words // the phrase the user should write down // res0: Vector = Vector(initial, cook, private, history, yard, agree, chicken, enough, stool, error, board, potato, frame, rather, link, hair, invest, hobby, multiply, tired, forget, between, path, swim) // the phrase the user should write down // the password argument is an optional, extra security // measure. mnemonicCode: MnemonicCode = Masked(MnemonicCodeImpl) the length of the entropy bit vector determine // how long our phrase ends up being // 256 bits of entropy results in 24 words val entropy: BitVector = MnemonicCode.getEntropy256Bits Use that to generate further private and public keys: import scodec.bits._ Here's aįull example of how to obtain a wallet seed, and then If you want to jump into the details of how this work,Ä«itcoin-S supports generating keys in this fashion. So different wallets can operate with the same standard. Seed can be used to generate an arbitrary amount of later Using the latest version of your Bitcoin software allows you to receive important stability and security fixes. Key generation has a root seed for each wallet, and this This is thanks to what's called HierarchicalÄeterministic key generation. ![]() In modern Bitcoin wallets, users only need to write downĪ sequence of words, and that sequence is a complete backup
