Installation

go get github.com/study/crypto-accounts

Usage

Generate Address

package main

import (
    "fmt"
    "github.com/study/crypto-accounts/pkgs/address"
)

func main() {
    factory := address.NewFactory()

    // Generate Ethereum address from public key
    publicKey := []byte{...} // 64-byte uncompressed public key
    addr, err := factory.Generate(address.ChainEthereum, publicKey)
    if err != nil {
        panic(err)
    }
    fmt.Println("Ethereum address:", addr)
}

Validate Address

package main

import (
    "fmt"
    "github.com/study/crypto-accounts/pkgs/address"
)

func main() {
    factory := address.NewFactory()

    // Validate Bitcoin address
    isValid := factory.Validate(address.ChainBitcoin, "1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa")
    fmt.Println("Valid:", isValid)
}

HD Wallet Key Derivation

package main

import (
    "fmt"
    "github.com/study/crypto-accounts/pkgs/bip32"
    "github.com/study/crypto-accounts/pkgs/bip39"
)

func main() {
    // Generate mnemonic
    mnemonic, _ := bip39.NewMnemonic(128) // 12 words

    // Derive seed
    seed := bip39.NewSeed(mnemonic, "")

    // Create master key
    masterKey, _ := bip32.NewMasterKey(seed)

    // Derive BIP-44 path: m/44'/60'/0'/0/0 (Ethereum)
    key, _ := masterKey.Derive(bip32.HardenedKeyStart + 44)
    key, _ = key.Derive(bip32.HardenedKeyStart + 60)
    key, _ = key.Derive(bip32.HardenedKeyStart + 0)
    key, _ = key.Derive(0)
    key, _ = key.Derive(0)

    fmt.Println("Public Key:", key.PublicKey())
}
