Get Native Token(NEO/GAS) and NEP5 Token from NEO blockchain

neon-js

This is a series of how you can start to build a decentralized app on the top of NEO. Before moving forward, I will guide you the fundamental aspect before we get started.

I am a full-stack javascript developer and one of the contributors for NEO blockchain project.

How To Get Started

NEO blockchain, programming tutorials, Javascript — 1

Get Native Token (NEO/GAS)

const Neon = require('@cityofzion/neon-js')
On Main Net
------------------------------------------
Neon
.default
.get
.balance('MainNet', 'Your Address')
.then(response => {
    response.assets.GAS.balance
    response.assets.NEO.balance
})
On Test Net
------------------------------------------
Neon
.default
.get
.balance('TestNet', 'Your Address')
.then(response => {
    response.assets.GAS.balance
    response.assets.NEO.balance
})

Get NEP5 Token from Binance

Fetch Binance NEP5 Token Balance(ONT)
1. Get ONT's script hash 
(Link to checkout all NEP5 script hash on Main Net)
ONT -> ceab719b8baa2310f232ee0d277c061704541cfb
2. Select the best RPC
(RPC monitor)
RPC endpoint -> https://pyrpc3.narrative.network:443
3. Binance Address
(Neon Scan)
Address -> AJzoeKrj7RHMwSrPQDPdv61ciVEYpmhkjk

Start to code
-----------------------------------------------
const Neon = require('@cityofzion/neon-js')
const rpcEndpoint = 'https://pyrpc3.narrative.network:443'
const address = 'AJzoeKrj7RHMwSrPQDPdv61ciVEYpmhkjk'
Neon
.api
.nep5
.getTokenInfo(rpcEndpoint, scriptHash)
.then(response => {
  response.name
  response.symbol
  response.totalSupply
  response.decimals
})
Neon
.api
.nep5
.getTokenBalance(rpcEndpoint, scriptHash, address)
.then(balance => {
  balance
})

Tip of the day

NEP5 is a smart contract standard if you want to do a ICO on the top of NEO.

Stay Tune

I will show you how to transfer native token(NEO/GAS) for my next tutorial.

I make one post on every Monday UTC+0 time zone, but if I have more than 500 claps, I make another post immediately.

Feel free to drop message to me if you want to suggest a topic for me.
