Supported Wallets

Automatically Supported Wallets

These wallets do not require you include any plugins. They run Scatter Protocols inside of their wallet and mimic our existing APIs.

Does your wallet support Scatter Protocols? Issue a Pull Request on the README.md and add it here.

dapp supported blockchains	platform	wallet
EOSIO, Tron, Ethereum	Scatter Desktop	Desktop
EOSIO, Ethereum	Scatter Extension	Desktop
EOSIO	TokenPocket	Mobile
EOSIO	MEET.ONE	Mobile
EOSIO	imToken	Mobile
EOSIO	PocketEOS	Mobile
EOSIO	MoreWallet	Mobile
EOSIO	NOVAWallet	Mobile

Plugin Supported Wallets

These wallets require a plugin to support. ScatterJS will mutate standardized blockchain library requests for you into their required formats.

dapp supported blockchains	wallet	platform	plugin
EOSIO	Lynx	Mobile	`scatterjs-plugin-lynx`

Installation

To use ScatterJS you must have at least the core. From that point forward you can mix-match the plugins you require.

blockchain library	installation command
eosjs	`npm i -S scatterjs-core scatterjs-plugin-eosjs eosjs@16.0.9`
eosjs2 (@20+)	`npm i -S scatterjs-core scatterjs-plugin-eosjs2 eosjs@20.0.0-beta3`
tronweb	`npm i -S scatterjs-core scatterjs-plugin-tron tronweb`
web3	`npm i -S scatterjs-core scatterjs-plugin-web3 web3`

Instantiation

As early as you can in your project, instantiate both ScatterJS and your selected plugins.

Nodejs

import ScatterJS from 'scatterjs-core';
import ScatterEOS from 'scatterjs-plugin-eosjs'

ScatterJS.plugins( new ScatterEOS() );

Vanilla

<script src="scatterjs-core.min.js"></script>
<script src="scatterjs-plugin-eosjs.min.js"></script>

<script>
    ScatterJS.plugins( new ScatterEOS() );
</script>

Multiple Plugins

import ScatterJS from 'scatterjs-core';
import ScatterEOS from 'scatterjs-plugin-eosjs'
import ScatterTron from 'scatterjs-plugin-tron'
import ScatterLynx from 'scatterjs-plugin-lynx'

ScatterJS.plugins( new ScatterEOS(), new ScatterTron(), new ScatterLynx() );

Build the network object

Networks tell Scatter which blockchain nodes you're going to be working with.

const network = ScatterJS.Network.fromJson({
    blockchain:'eos',
    chainId:'aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906',
    host:'nodes.get-scatter.com',
    port:443,
    protocol:'https'
});

Connect to an available wallet

Once you are connected you can then call API methods on ScatterJS

ScatterJS.connect('MyAppName', {network}).then(connected => {
    if(!connected) return false;
    // ScatterJS.someMethod();
});

You can see full scatterjs-core API docs here

Getting Blockchain Accounts

Login with the network passed into ScatterJS.connect

ScatterJS.login().then(...);

Login with multiple networks

ScatterJS.login({accounts:[network1, network2]).then(...);

Logout

ScatterJS.logout().then(...);

After a successful login, the "Identity" will be available at ScatterJS.identity. If a user refreshes the page and has already logged in, the ScatterJS.identity property will be auto-filled.

Get blockchain accounts from the identity

Because accounts are nested within the Identity there is an easy method for fetching them.

Using the helper

const account = ScatterJS.account('eos')
// Result: {name:'...', authority:'active', publicKey:'...', blockchain:'eos', chainId:'...'}

const account = ScatterJS.account('eth')
// Result: {address:'...', blockchain:'eth', chainId:'1'}

const account = ScatterJS.account('trx')
// Result: {address:'...', blockchain:'trx', chainId:'1'}

From the Identity

const account = ScatterJS.identity.find(x => {
    return x.blockchain === 'eos';
});

Using Blockchain Wrappers

Blockchain wrappers wrap the actual blockchain libraries (eosjs, tronweb, web3, etc) that you pass in. That way you don't have to relearn any APIs or be forced to use any specific version.

You can click on the libraries here below to go directly to their respective githubs.

eosjs@16.0.9 ( scatterjs-plugin-eosjs )

import Eos from 'eosjs';
const eos = ScatterJS.eos(network, Eos, eosjsOptions);

const result = await eos.transfer(...);

eosjs@20.0.0-beta3 ( scatterjs-plugin-eosjs2 )

import {JsonRpc, Api} from 'eosjs'
const rpc = new JsonRpc(network.fullhost());
const eos = ScatterJS.eos(network, Api, {rpc, beta3:true}));
<br/>
const result = await eos.transact({...});

tronweb

import TronWeb from 'tronweb';
const httpProvider = new TronWeb.providers.HttpProvider(network.fullhost());
let tron = new TronWeb(httpProvider, httpProvider, network.fullhost());
tron.setDefaultBlock('latest');
tron = ScatterJS.trx(network, tron);

const result = await tron.trx.sendTransaction(...)

web3

import Web3 from 'web3';
const web3 = ScatterJS.web3(network, Web3);

const result = await web3.eth.sendTransaction(...)

NodeJS and babel/webpack issues.

If you're having trouble packaging or compiling your project you probably need to add a babel transpiler.

npm i -D @babel/runtime <-- run this command and it should compile.

If you're using eosjs beta3

const eos = scatter.eos(network, Api, { rpc, beta3:true })

What now?

Head over to the Scatter Developer Documentation to learn about all the amazing things you can do with Scatter.

There's also a lot more information about proper setup in the Setting up for Web Applications section which will help you get the most out of ScatterJS, and make sure you aren't exposing your users to malicious non-Scatter plugins.
