# go-ethereum-hdwallet

> Ethereum HD Wallet derivations from [mnemonic] seed in Go (golang). Implements the [go-ethereum](https://github.com/ethereum/go-ethereum) [`accounts.Wallet`](https://github.com/ethereum/go-ethereum/blob/master/accounts/accounts.go) interface.

## Install

```bash

go get -u github.com/miguelmota/go-ethereum-hdwallet

```

## Documenation

[https://godoc.org/github.com/miguelmota/go-ethereum-hdwallet](https://godoc.org/github.com/miguelmota/go-ethereum-hdwallet)

## Getting started

```go

package main

import (

	"fmt"

	"log"

	"github.com/miguelmota/go-ethereum-hdwallet"

)

func main() {

	mnemonic := "tag volcano eight thank tide danger coast health above argue embrace heavy"

	wallet, err := hdwallet.NewFromMnemonic(mnemonic)

	if err != nil {

		log.Fatal(err)

	}

	path := hdwallet.MustParseDerivationPath("m/44'/60'/0'/0/0")

	account, err := wallet.Derive(path, false)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println(account.Address.Hex()) // 0xC49926C4124cEe1cbA0Ea94Ea31a6c12318df947

	path = hdwallet.MustParseDerivationPath("m/44'/60'/0'/0/1")

	account, err = wallet.Derive(path, false)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println(account.Address.Hex()) // 0x8230645aC28A4EdD1b0B53E7Cd8019744E9dD559

}

```

### Signing transaction

```go

package main

import (

	"log"

	"math/big"

	"github.com/davecgh/go-spew/spew"

	"github.com/ethereum/go-ethereum/common"

	"github.com/ethereum/go-ethereum/core/types"

	"github.com/miguelmota/go-ethereum-hdwallet"

)

func main() {

	mnemonic := "tag volcano eight thank tide danger coast health above argue embrace heavy"

	wallet, err := hdwallet.NewFromMnemonic(mnemonic)

	if err != nil {

		log.Fatal(err)

	}

	path := hdwallet.MustParseDerivationPath("m/44'/60'/0'/0/0")

	account, err := wallet.Derive(path, true)

	if err != nil {

		log.Fatal(err)

	}

	nonce := uint64(0)

	value := big.NewInt(1000000000000000000)

	toAddress := common.HexToAddress("0x0")

	gasLimit := uint64(21000)

	gasPrice := big.NewInt(21000000000)

	var data []byte

	tx := types.NewTransaction(nonce, toAddress, value, gasLimit, gasPrice, data)

	signedTx, err := wallet.SignTx(account, tx, nil)

	if err != nil {

		log.Fatal(err)

	}

	spew.Dump(signedTx)

}

```
