# 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)
}
```
