💫 Getting Started

Import the library:

import PWRJS from "@pwrjs/core";
import Wallet from "@pwrjs/core/wallet";

// or
const PWRJS = require('@pwrjs/core');
const Wallet = require('@pwrjs/core/wallet');

Create a new instance

const pwrjs = new PWRJS('https://pwrrpc.pwrlabs.io');

Generate a new random wallet:

const wallet = Wallet.newRandom(12);

Import wallet by Seed Phrase:

const seedPhrase = "your seed phrase here";
const wallet = Wallet.fromSeedPhrase(seedPhrase);

Get wallet address:

const address = wallet.getAddress();

Get wallet seed phrase:

const seedPhrase = wallet.getSeedPhrase();

Get wallet balance:

const balance = await wallet.getBalance();

Transfer PWR tokens:

const recipientAddress = '0x...';
const pwrAmount = '1000000000'; // 1 PWR = 10^9
await wallet.transferPWR(recipientAddress, BigInt(pwrAmount));

Sending a transcation to the PWR Chain returns a Response object, which specified if the transaction was a success, and returns relevant data. If the transaction was a success, you can retrieive the transaction hash, if it failed, you can fetch the error.

try {
    const response = await wallet.transferPWR(recipientAddress, BigInt(pwrAmount));

    if (response.sucess) {
        console.log('Transcation Hash: ' + response.hash);
    }
} catch (e) {
    console.log(e);
}

Send data to a vida:

const vidaId = BigInt('123');
const data = new TextEncoder().encode('Hello world');

try {
    const response = await wallet.sendVidaData(vidaId, data);
    if (response.sucess) {
        console.log('Transcation Hash: ' + response.hash);
    }
} catch (e) {
    console.log(e);
}

Other Static Calls

Get RPC Node Url:

Returns currently set RPC node URL.

const url = await pwrjs.getRpcNodeUrl();

Get Fee Per Byte:

Gets the latest fee-per-byte rate.

const fee = await pwrjs.getFeePerByte();

Get Balance Of Address:

Gets the balance of a specific address.

const balance = await pwrjs.getBalanceOfAddress('0x...');

Get Nonce Of Address:

Gets the nonce/transaction count of a specific address.

const nonce = await pwrjs.getNonceOfAddress('0x...');

Broadcast Txn:

Broadcasts a signed transaction to the network.

const signedTransaction = '...';
const broadcast = await pwrjs.broadcastTxn(signedTransaction);
