Go-BIP44

A Golang implementation of the BIP44 for Hierarchical Deterministic (HD) addresses. It currently only supports Bitcoin.

Should I use this in production?

This library is in very early stages. Please be aware that some bugs may exist.

Can I trust this code?

Do not trust. Verify.

Since this lib is in its early days, we recommend every user of this library audit and verify any underlying code for its validity and suitability. You can do so by using this tool.

Installation

go get -u github.com/motopig/go-bip44

Usage

New 24-word Mnemonic and Seed

// bitSize must be a multiple of 32
bitSize := 256
mnemonic, _ := bip44.NewMnemonic(bitSize)
seedBytes := m.NewSeed("my password")

Master key From Seed Hex - (Unstable yet)

xKey, _ := bip44.NewKeyFromSeedHex("your secret seed in hex format", bip44.MAINNET)

Master key From Seed bytes - (Unstable yet)

xKey, _ := bip44.NewKeyFromSeedBytes(seedBytes, bip44.MAINNET)

From base58-encoded Extended Key

ak, _ := bip44.NewAccountKeyFromXPubKey(xPubKey)

externalAddress, _ := accountKey.DeriveP2PKAddress(bip44.ExternalChangeType, 0, bip44.MAINNET)
internalAddress, _ := accountKey.DeriveP2PKAddress(bip44.InternalChangeType, 0, bip44.MAINNET)

Deriving P2PK addresses

coin	account	chain	address	path
Bitcoin	first	external	first	m / 44' / 0' / 0' / 0 / 0

xKey, _ := bip44.NewKeyFromSeedHex("your secret seed in hex format", bip44.MAINNET)
accountKey, _ := xKey.BIP44AccountKey(bip44.BitcoinCoinType, 0, true)

externalAddress, _ := accountKey.DeriveP2PKAddress(bip44.ExternalChangeType, 0, bip44.MAINNET)

coin	account	chain	address	path
Bitcoin	first	external	second	m / 44' / 0' / 0' / 0 / 1

xKey, _ := bip44.NewKeyFromSeedHex("your secret seed in hex format", bip44.MAINNET)
accountKey, _ := xKey.BIP44AccountKey(bip44.BitcoinCoinType, 0, true)

externalAddress, _ := accountKey.DeriveP2PKAddress(bip44.ExternalChangeType, 1, bip44.MAINNET)

coin	account	chain	address	path
Bitcoin Testnet	second	internal	first	m / 44' / 1' / 1' / 1 / 0

xKey, _ := bip44.NewKeyFromSeedHex("your secret seed in hex format", bip44.TESTNET3)
accountKey, _ := xKey.BIP44AccountKey(bip44.TestnetCoinType, 1, true)

externalAddress, _ := accountKey.DeriveP2PKAddress(bip44.InternalChangeType, 0, bip44.TESTNET3)
