Author: GeekCash Team
Latest version: 1.1.1

Block and Transaction Real-Time Broadcasting
===============

A client library to connect to Multiple RPC in JavaScript. This's library support all coins based Dash.

## Get Started

```
npm i smart-rpc
```
	
## Listen multiple rpc
```js
var SmartRPC = require('smart-rpc');

var options = [{
    id: 'GeekCash',
    socket: 'tcp://127.0.0.1:12345',
    listen: 1,
    rpc: {
        url: 'http://127.0.0.1:6888/',
        method: 'POST',
        auth: {
            username: 'user',
            password: 'password'
        },
    }
},
{
	id: 'Dash',
    socket: 'tcp://127.0.0.1:56789',
    listen: 1,
    rpc: {
        url: 'http://127.0.0.1:9998/',
        method: 'POST',
        auth: {
            username: 'user',
            password: 'password'
        },
    }

}];

SmartRPC.listen(options);

SmartRPC.on('error', function (rpc, error) {        
	console.log('error', rpc.id, error);
});

SmartRPC.on('hashblock', function (rpc, val) {        
	console.log('block', rpc.id, val);
});

SmartRPC.on('block', function (rpc, val) {        
	console.log('block', rpc.id, val);
});

// SmartRPC.on('rawtx', function (rpc, val) {
// 	console.log('rawtx', rpc.id, val);
// });

SmartRPC.on('tx', function (rpc, val) {
	console.log('tx', rpc.id, val.txid);
});

## rpc client
```js

var option = {
    id: 'GeekCash',
    socket: 'tcp://127.0.0.1:12345',
    listen: 1,
    rpc: {
        url: 'http://127.0.0.1:6888/',
        method: 'POST',

            username: 'user',
            password: 'password'
        },
    }
};

var client = SmartRPC.create(option);

```
```js

client.on('ready' function(){
    console.log('Daemon is Ready!');

});
```

```js

// Returns hash of block in best-block-chain at index provided.

// Arguments:
