+Ethereum wallet
+------
+
+This repository contains the golang code of a simple ethereum wallet and a RESTful API server can 
+get information from etherscan and node. 
+
+Contents
+--------
+- [Feature](#feature)
+- [Setup](#setup)
+- [Example](#example)
+- [Test](#test)
+
+Feature
+--------
+- create keystore
+- get address's balance(eth, erc20), transaction, nonce from node
+- estimate transaction's gas limit
+- get gasprice from node
+- get address's transaction history(eth, erc20) from etherscan api
+- send eth, erc20 from your address to another address
+- sign message, sign transaction
+- verify message
+
+Setup
+------
+
+## Setup config
+
+### config path
+
+Environment variable: ETHEREUM_WALLET_CONFIG_PATH
+
+if you don't set env, then default path is config.json in the current folder.
+
+### config.json
+
+#### Variable
+
+- `network(not necessary)`: defalut network, you can choose ropsten, rinkeby or mainnet.  
+- `ropsten, rinkeby, mainnet`: network's node_url and etherscan_api_url need to be set in here, `node_url`
+  is ethereum node's url, you can choose to use infura(https://infura.io/), `etherscan_api_url` is
+  etherscan's developer api url.  
+- `etherscan_api_key`: etherscan's api key, you can register at etherscan(https://etherscan.io/apis)
+- `server_url(not necessary)`: server's url when use start server command, default is set in http://127.0.0.1:8080  
+- `keyfile`: keystore's path, you can create keystore from cli create command  
+- `passphrase(not necessary)`: keystore's passphrase, it's a fast way to unlock keyfile, or you can input in terminal when cli need unlock wallet  
+- `address(not necessary)`: default query address  
+- `erc20_list`: erc20 token's list, you need provide token's decimals, name, symbol, I put some popular 
+  erc20 token in project's erc20_list.json file, user can add token you need in config file.
+
+#### Example
+```
+{
+{
+  "network": "ropsten",

+
+## Build 
+
+```shell script

+## Run
+
+### run server first
+```shell script
+./cli server start -network ropsten
+```
+
+### do what you want to do
+```shell script
+./cli
+```
+
+Example
+-------

+
+### NodeWallet wallet
+
+#### send ether to other address
+
+- The unit needs to be expressed in the form of wei
+
+```shell script
+./cli nodewallet sendether -keyfile "./keystore/test" -to "0x51bf0b41Ba5B034f158CF1233f16bA5450F9355B" -value 10000000000
