## What is TronWeb?



[TronWeb](https://tronweb.network) aims to deliver a unified, seamless development experience influenced by Ethereum's [Web3](https://github.com/ethereum/web3.js/) implementation. We have taken the core ideas and expanded upon them to unlock the functionality of TRON's unique feature set along with offering new tools for integrating DApps in the browser, Node.js and IoT devices.



To better support its use in TypeScript projects, we have rewritten the entire library in TypeScript. And to make the TronWeb API more secure and consistent, there are some breaking changes. Please check out [6.x API documentation](https://tronweb.network/docu/docs/intro/) for detailed changes so you can start using the new TypeScript version of TronWeb early. Any questions or feedback are welcome [here](https://github.com/tronprotocol/tronweb/issues/new).



**Project scope**



Any new TRON feature will be incorporated into TronWeb. Changes to the API to improve quality-of-life are in-scope for the project. We will not necessarily maintain feature parity with Web3.js going forward as this is a separate project, not a synchronized fork.

## Compatibility

- Version built for Node.js v14 and above

- Version built for browsers with more than 0.25% market share



You can access either version specifically from the dist folder.



TronWeb is also compatible with frontend frameworks such as:

- Angular

- React

- Vue.



You can also ship TronWeb in a Chrome extension.



## Recent History



For recent history, see the [CHANGELOG](https://github.com/tronprotocol/tronweb/blob/master/CHANGELOG.md). You can check it out for:

- New features

- Dependencies update

- Bug fix



## Installation



### Node.js

```bash

npm install tronweb

```

or

```bash

yarn add tronweb

```



### Browser



The easiest way to use TronWeb in a browser is to install it as above and copy the dist file to your working folder. For example:

```

cp node_modules/tronweb/dist/TronWeb.js ./js/tronweb.js

```

so that you can call it in your HTML page as

```

<script>

```



This project is also published on NPM and you can access CDN mirrors of this release (please use sub-resource integrity for any `<script>` includes).



## Testnet



Shasta is the official Tron testnet. To use it use the following endpoint:

```

https://api.shasta.trongrid.io

```

Get some Shasta TRX at https://www.trongrid.io/shasta and play with it.

Anything you do should be explorable on https://shasta.tronscan.org



## Your local private network for heavy testing



You can set up your own private network, running Tron Quickstart. To do it you must [install Docker](https://docs.docker.com/install/) and, when ready, run a command like



```bash

docker run -it --rm \

  -p 9090:9090 \

  -e "defaultBalance=100000" \

  -e "showQueryString=true" \

  -e "showBody=true" \

  -e "formatJson=true" \

  --name tron \

  trontools/quickstart

```

## Creating an Instance



First of all, in your typescript file, define TronWeb:



```typescript

import { TronWeb, utils as TronWebUtils, Trx, TransactionBuilder, Contract, Event, Plugin } from 'tronweb';

```



Please note that this is not the same as v5.x. If you want to dive into more differences, check out [migration guide](https://tronweb.network/docu/docs/6.0.0/Migrating%20from%20v5)



When you instantiate TronWeb you can define



* fullNode

* solidityNode

* eventServer

* privateKey



you can also set a



* fullHost



which works as a jolly. If you do so, though, the more precise specification has priority.

Supposing you are using a server which provides everything, like TronGrid, you can instantiate TronWeb as:



```js

const tronWeb = new TronWeb({

    fullHost: 'https://api.trongrid.io',

    headers: { "TRON-PRO-API-KEY": 'your api key' },

    privateKey: 'your private key'

})

```



For retro-compatibility, though, you can continue to use the old approach, where any parameter is passed separately:

```js

const tronWeb = new TronWeb(fullNode, solidityNode, eventServer, privateKey)

tronWeb.setHeader({ "TRON-PRO-API-KEY": 'your api key' });

```



If you are, for example, using a server as full and solidity node, and another server for the events, you can set it as:



```js

const tronWeb = new TronWeb({

    fullHost: 'https://api.trongrid.io',

    eventServer: 'https://api.someotherevent.io',

    privateKey: 'your private key'

  }

)

```



If you are using different servers for anything, you can do

```js

const tronWeb = new TronWeb({

    fullNode: 'https://some-node.tld',

    solidityNode: 'https://some-other-node.tld',

    eventServer: 'https://some-event-server.tld',

    privateKey: 'your private key'

  }

)

```



## Integrity Check



The package files will be signed using a GPG key pair, and the correctness of the signature will be verified using the following public key:



```
