# CKB SDK Golang
[](https://github.com/ququzone/ckb-sdk-go/blob/master/LICENSE)
[](https://github.com/moovweb/gvm)
[](https://t.me/nervos_ckb_dev)
Golang SDK for Nervos [CKB](https://github.com/nervosnetwork/ckb).
## Get started
### Minimum requirements
| Components | Version | Description |
|----------|-------------|-------------|
| [Golang](https://golang.org) | ≥ 1.11.5 | Go programming language |
### Install
```bash
go get -v github.com/ququzone/ckb-sdk-go
```
## Basic Usages
### 1. Single input send transaction
```go
package main

if err != nil {
log.Fatalf("import private key error: %v", err)
}
systemScripts, err := utils.NewSystemScripts(client)
if err != nil {
log.Fatalf("load system script error: %v", err)
}
toAddress, _ := hex.DecodeString("bf3e92da4911fa5f620e7b1fd27c2d0ddd0de744")
