Usage

Connecting to Decimal Blockchain

You can provide your own Decimal node address to send transactions to the network, or you can use our gateways to do this and much more. Gateway URLs are provided below.

The following code can be used to generate mnemonic or use your mnemonic

const bip39 = require("bip39");
const mnemonic = bip39.generateMnemonic();

Example: Send a transaction

import { Wallet, Decimal, DecimalNetworks } from 'dsc-js-sdk' 

// connect decimal sdk to gateway or node
const decimal = await Decimal.connect(DecimalNetworks.devnet);

// get decimal wallet from mnemonic and set it to decimal instance
const decimalWallet = new Wallet(mnemonic);
decimal.setWallet(decimalWallet);

// prepare message
const msgSendCoin = {
  to: 'd01epqerywtrgalfl7qytgplptatt776qd65p64w6',
  coin: 'del',
  amount: '300'
}

// set transaction options
const options = {
  feeCoin: "", // network native coin by default (del/tdel)
  message: "memo",
  txBroadcastMode: "sync",
}

// create transaction sender
const sender = await decimal.transactionSender(); 
// send transaction
const res = await sender.sendCoin(msgSendCoin, options);

Different modes of sending transaction

...
// using our gateway to send transactions - the simpliest way
const decimal = await Decimal.connect(DecimalNetworks.devnet);

// pass the second parameter to specify mode (by default === false)
// in this case you will be using our node
const isNodeDirectMode = true;
const decimal = await Decimal.connect(DecimalNetworks.devnet, isNodeDirectMode);

// advanced users can use their own node rest and rpc endpoints
const nodeEnpoints = {
  rest: 'http://127.0.0.1:1317',
  rpc: 'http://127.0.0.1:26657'
}
const isNodeDirectMode = true;
const decimal = await Decimal.connect(DecimalNetworks.devnet, isNodeDirectMode, nodeEnpoints);
