Install and Initialize

Overview

Portkey injects a global JavaScript API into websites visited by its users using the window.Portkey provider object. This API allows websites to request users' AA accounts, read data from blockchains the user is connected to, and suggest that the user sign messages and transactions.

Installation

• NPM
• YARN

npm install @portkey/detect-provider

Basic Usage

import detectProvider from '@portkey/detect-provider';

// ES6 Async/Await syntax
const provider:IPortkeyProvider = await detectProvider();

// ES6 Promise syntax
detectProvider().then((provider:IPortkeyProvider) => {
  // do something with provider
  provider.request({method: ... })
}).catch((error:Error) => {
  // Handle error
});

Get Started

Quick Start

import detectProvider from 'detect-provider';

const provider = await detectProvider();

if (provider) {
  // From now on, this should always be true:
  startApp(provider); // initialize your app (startApp: This is a user-defined function.)
} else {
  console.log('Please install Portkey!');
}
// get accounts
const accounts = await provider.request({method:"requestAccounts"})
// {AELF:["AELF_Address"],tDVV:["tDVV_Address"]}

// get chain
const chain = await provider.getChain('AELF');

// status
const status =  await chain.getChainStatus();

// get contract
const tokenC = await chain.getContract('token contract address');

// Transfer
const req = await tokenC.callSendMethod('Transfer',accounts.AELF[0],{amount:100000,symbol:"ELF",to:'xxx'})

// GetBalance
const req = await tokenC.callViewMethod('GetBalance',{symbol: 'ELF',owner: "owner"})
